Manual talk:Installation

Anyways mediawiki
doesnt seem to work with addon domains. The website is nationofshadows.com but the directory is root/public_html/nationofshadows. Can someone help me out. When i open the localsettings.php it says "This file is part of MediaWiki and is not a valid entry point". I dont understand what is going on. I am so upset cause I actually had to upgrade my server software which meant thsadasat i had to move my ENTIRE website including all 5 of my domains to a different box for the sole purpose of getting mediawiki. And now i cant install just cause it is on an addon domain!

Conclusion: MediaWiki does not play well with others.^_^


 * I'm experiencing the same problem, I think. I've installed mediawiki to test.domain.tld, and it doensn't work. I'll try to re-install it in the www-space now. 62.233.4.3 08:53, 27 November 2006 (UTC)

Uploading images: Which function actually makes the upload?
Hi,

I have massive problems with safe mode and uploading images to my wiki. I did create the directories and made them 777. I did apply the changes to the LocalSettings.php. But I still get errors like Could not copy file "/tmp/php8DaiV2" to "/home/ws/ry149/.public_html/wiki/images/Cutplane_snapshot.png".' I have no idea what could cause this error.

Now I am looking for the function call that actually makes the upload of chosen file to the /tmp/somename file. I only find the function that copies/moves the tmp file to the correct named file.

I use Wiki 1.5.3. I found the function 'function processUpload' in 'SpecialUpload.php'. This functions comments made me think that this is the function I am looking for. But I can't find the part that uploads the local file to tmp/somename.

Please please please...

Someone an idea?

Thanks, K.B.

I also have similar problems. For you I would make sure that your server isn't running in safe-mode. Also there may be imagemagick issues. Personally i get " Warning: shell_exec has been disabled for security reasons in /home/.iroquois/zorlac/sporewiki.com/includes/Image.php on line x" when it tries to create thumbnails. Safe-mode is off, chmodding is correct, path to imagemagick is correct. -Zorlac

Where can I go for help??
Hi,

I really need help upgrading my version of MediaWiki. I was wondering if there's a forum I can go to for help? The thing I find about this Wiki, and in general - there's just no central place for help. Am I meant to post questions here, or where? It's all so disorganised.

Anyway, my problem is that I've just upgraded from 1.4 ro 1.5rc4 because we need good user management. Now, there's very little documentation about upgrading, and what there is implied that this was possible, and that the data itself would just be upgraded fine.

So I backed up my database and then did the upgrade. The upgrade worked, except now all my data is gone. The little info there is on upgrading did not say this was going to happen!! So my question now is, how do I restore my data? I've got it in SQL statements and an XML file.

But I'm guessing I can't just run those SQL INSERT's to restore it because the structure has changed.

What do I do?

thanks if anyone reads this. (86.128.156.139 12:55, 15 September 2005 (UTC))

I have set up a forum MediaWiki Users It's brand new but hopefully some knowledgeable people will find it and contribute. As for your DB, you might be able to use phpmyadmin to restore it. -TS

Troubleshooting
If you cannot use the install script for some reason, follow these steps

Can't Even Get Started
Okay, so I've unzipped the mediawiki file and uploaded all of the files to my hosting server. I don't see any "config" file or anything that looks like a directory (just regular files). I am not a programmer by any definition, so maybe I just don't know what to look for. When I click over to the /wiki folder in my brower, I'm told I don't have permission to look at the page.

Help!! (email@tonyfleming.org)
 * I'm on the same boat. I also want My very own wiki site but we need a tutorial ([mailto:Eddie@EddieSegoura.com Eddie@EddieSegoura.com]) -- EddieSegoura 10:25, 1 January 2006 (UTC)

- Try changing the permissions in the window where you uploaded the files to the server. Right click on the file (where it's hosted) and selected properties (or attributes). There will be an area where you can check boxes, giving permissions.

Running in a subdomain
I found that installation itself was fine, but due to the way redirects work, I haven't been able to get the wiki to be addressable from both the subdomain and the subdirectory of my site.


 * http://wiki.mydomain.com    needs $wgScriptPath= "";
 * http://www.mydomain.com/wiki needs $wgScriptPath= "/wiki";

So the two aren't compatible. If I choose the latter configuration, I get page not found from the subdomain. If I choose the former, I get bad wiki links in the subdirectory.

I have the same problem. Anyone know how to work around this?

Questions about installation (apache and domains for languages at webhost)
Two questions about installation, and thanks very much to anyone who can help! I want to upload mediawiki on a domain provided by a web host, which will be paid for. But I am less than an amateur about installing things like MediaWiki, and could use really some help.


 * 1) It says on the Installation page that you first need MYSQL, and PHP, and Apache. The web hosts I am considering all say they have MYSQL and PHP, but none of them mention Apache. Once I have the domain thru my web host, can I upload Apache myself? How?
 * 2) I want to start with more than one language domain, like in Wikipedia. To do that, when I purchase space from my webhost, must I purchase a license for more than one domain? Or are the language domains really subdomains?
 * 3) Is there some sort of easy step-by-step guide for "regular" people like me who purchase space on a web server, and have never set up a website before?

Thanks!
 * Apachee is the name of the web server. The webhost you are using is probably already running apachee. If they are not you will need to move to one that is running apachee. I imageing you could get MediaWiki to work on other servers but it would not be worth the effort.
 * Language domains can be just subdomains. Yoiu should be able to use either in exactly the same way.
 * This guide is the only such guide i know.

Minimum system requirements

 * Question from 129.42.208.182 moved from Help page:

How much RAM does PHP require on a unix webhost ?

Installation goes nowhere
I successfully went throught all steps of the installation process. In the end the install tutorial even said " installation succesfull, now visit your wiki!" But when I do visit the wiki nothing happens. I mean, really nothing, the page loads, stop and it seems I am still in the same page I was before. I tested in a pc (Firefox & ie) and a mac (safari & mozilla). Only safari did something different that was to give me the following error message:

Safari can't open the page. Safari can't open the page: "http://www.wanderingabout.com/kiwi/index.php/Main_Page" because it could not load any data from this location.

I am completely lost, any tip? If it helps, the only warning output was about my "register globals" being activated which seemed a minor security issue, and the information that the problem persisted even afetr I changed folder permissions (chmod) back o normal.. --Avsa 20:05, 14 Mar 2005 (UTC)

After Installation Missing images
I went through the installation process without problems. Uploaded the latest cur file and the Wikimedia Commons images used on the English Wikipedia. Everything works except that the images don't display. I know there is something simple I've missed and would appreciate any hints. Thanks

Moving an installation
How does one go about moving an installation of MediaWiki to a new location on a server? Can I assume that I can move the entire directory and that I'll then need to make changes to my database? If so, what are the changes necessary?

In my specific case, I am running a wiki at http://www.blisteredavalon.com/wiki/index.php, which can currently be accessed through the redirect domain http://pcpedia.blisteredavalon.com. I have decided I want to change http://pcpedia.blisteredavalon.com to a fully hosted subdomain and run the wiki from there, instead (now that I know how to add a fully hosted subdomain to my site).

Galatea 17:46, 23 Mar 2005 (UTC)

> It seems to me like f it works with your redirect from the http://pcpedia.blisterredavalon.com/ URL, moving it to the same FQDN shouldn't hurt it. I'm about to try moving mind from one FQDN to another, and if it works, I'll let you know.

.htaccess
my hosting "company" does not allow .htaccess files to used. all such changes must be made through a web interface. What do I need to do to make MediaWiki work? GigaClon

My miserable experience
I have previously installed Wikimedia on my Windows desktop on top of EasyPHP. Everything went very smoothly. Today I decided to try to install Wikimedia on our SuSE server. I expected it to me pretty easy. No such luck. The information here about installing Apache, PHP, MySQL etc is woefully inadequate. I've spent most of the day hacking around and am getting pretty close - I'm at config/index.php, but cannot access the MySQL database... User:Very Frustrated 13:04, 7 May 2005 (UTC)
 * Update: Actually a lot of the problems I encountered were a consequence of me installing the wrong versions of Apache and MySQL on SuSE. I got different results depending on whether I use the SuSE graphical packing managemnt tool or the shell RPM command.  SuSE seems to be not very joined up in this respect.  Once I got the right packages installed then the Wikimedia install was nice and smooth. User:Very Happy Now 10:13, 10 Jun 2005 (UTC)

Move or copy LocalSettings.php?
The install process says "To complete the installation, move config/LocalSettings.php to the parent directory.". But this wiki page says to copy it.

>You can copy it or move it, as far as I know, and since copying it is less destructive, it's what I did. The LocalSettings.php that the Wiki uses is the one in the parent directory.

Move is just as good, it suggests to remove the config/ directory for added security anyway

You can place it in the root and if you have access to the httpd.conf, setup a symlink.
Create a symlink from what to where?!?

What I tried which works: 1) download the tar file to /tmp, 2) create the document root for the (virtual) web server (or use /usr/local/www/data), 3) unpack the directory, 4) symbolic link from 'wiki' to 'mediawiki-VERSION'.: cd /usr/local/www/virtuals/mediawiki.example.com tar xvfz /tmp/mediawiki-1.6.8.tar.gz ln -s mediawiki-1.6.8 wiki

The statement about httpd.conf doesn't seem to be anything to do with the symbolic link -- you only need to change httpd.conf if you need to tell your web server software (presumed to be Apache) about your new virtual server.

When I do this again I might try just renaming the directory: mv mediawiki-1.6.8 wiki

Hope this helps someone.

Jonathan.

Help needed
Okay, I need alittle help on this one. The server is Lycos. PHP 4.3.10 MySQL 4.0.18 Upload and post max size 50MB. Max execution 30MB, Memory limit 16MB. These functions are disabled, but they claim I should be able to run Mediawiki:

I checked, and the file wiki/includes/Defines.php does exist. So what´s going on here? -- Redge (Talk) 17:56, 30 May 2005 (UTC)


 * I have the same issue, and I think I see what it means. I don't know how to fix it however.

The script has a comment saying require_once breaks if a directory in the path is not readable, and tries to work around it with a set_ini changing te include path - which is disabled, so no workaround. Apart from moving files around, I don't see a solution. Here's the relevant bit of config/index.php $IP = dirname( dirname( __FILE__ ) ); $sep = (DIRECTORY_SEPARATOR == "\\") ? ";" : ":"; ini_set( "include_path", ".$sep$IP$sep$IP/includes$sep$IP/languages" );
 * 1) Relative includes seem to break if a parent directory is not readable;
 * 2) this is common for public_html subdirs under user home directories.
 * 3) As a dirty hack, we'll try to set up the include path first.

mysql permissions
Given that the mysql user and password are within the LocalSettings.PHP file, what should I change the permissions to after the initial setup?

> 400 and making the owner the user that runs the web server should work. Possibly 600 if it needs to change it but I doubt it.

need troubleshooting help
I installed per the instructions, and all seemed to go fine. However, when I use the wiki I find that I can only save edits as an anonymous user. When I log in as a user, even a sysop, I can no longer save my edits. I can not save any user preferences either. It seems I can no longer update anything in the database once I've logged in. When I log out, I can again save edits.

Any ideas? I'm stumped.

I have the same exact problem and if you fix it I'd greatly appreciate if you could let me know on my talk page. Thanks, I'll be searching too and let you know if I find anything. Shashe 23:35, 21 October 2005 (UTC)

System requirements / software requirements
This page should probably include details of minimum and recommended software requirements. From attempting an installation I know that

WARNING: PHP 4.3.2 or higher is recommended. Older versions from 4.1.x up may work but are not actively supported.

I'm getting similar errors. It looks like the program's looking for the /maintenance directory inside index.php, which fails. Perhaps one of the mirrors has a bad version of the file? I'm going to try downloading from a different mirror and see if that will work.

Downloading from a different mirror worked.

bypassing mysql root user
is there a way to bypass requiring a mysql root user on the first install screen? i've created a database already as well as a new user/pass specifically for mediawiki, but it wants to recreate the same database. $$\frac{aack}{aaahh}$$

Installation Error Message "No input file specified"
I have tried to set up the following combination - mediaWiki 1.4.7 on PHP 5.0.4 with MySQL 4.1.13 on IIS 6.0 (Windows 2003 Server). However, when I actually try to access the wiki for the first time I get redirected to index.php/Main_Page (which is good), but then get an almost-blank page with the message:

"No input file specified"

I can run PHP scripts and can send queries to the MySQL database (so I don't think there are any problems there). I only get the error after I have been told that everything is set up, and after having copied the LocalSettings.php file into the parent directory.

Can anyone give me any guidance on what is going wrong? I have looked at permissions, and have set it so that IUSR can "Read & Execute" and "Write" to the entire mediawiki tree, but I cannot get away from the message. I have also tried installing 1.5beta4, which appears to install fine, but gives exactly the same message at the end. --Sf-andrew 18:56, 9 August 2005 (UTC)

'''Solution: It appears that my setup requires "ugly URLs"! This means the following in LocalSettings.php:
 *  # $wgArticlePath     = "$wgScript/$1"; 
 *  $wgArticlePath     = "$wgScript?title=$1"; 

'''Another Question On This Topic: I am having the same problem with the "No input file specified" error on the index.php in my root wiki directory. I am running WIMP (PHP 5.2, MySQL 5.0.27 on IIS 5). I enabled "ugly URLs" on the auto install page and double checked LocalSettings.php per above. I have this set up in ISAPI mode. Any other ideas what may be causing this problem?

Thanks, Jay

Yet Another Question about this error message  I got the same error message when I first tried browsing the directory. I had followed the windows installation info and put the mediawiki in a directory outside of the webroot and created a virtual directory. When I finally moved the files to the web root, the "no input" message went away and the install sailed through. Could we have a path problem here? I'm not familiar enough with IIS to be sure what is happening. 24 January 2007

What sould I do?Thank you

Hello, Same problem on Lycos FR. thank you for helping us ...

Installation of Help: files
This is probably not the right place for this request, but MediaWiki really needs a (simple?) documented process for populating the Help: namespace in a new installation. Oh, and a set of help pages to go with it that don't have links to other namespaces that are not present in a standard installation -- this Meta-wiki's help pages would be a good starting point, but they do contain many links outside of the Help: namespace and to pages that are only relevent here.

Clarify database creation step
In step 3, about creating a database, the second paragraph says

"If you have root access, the setup file will ask you for the root password and automatically setup the database for you. See MySQL config for more details."

This is the first reference to "the setup file". It's not clear to me if this means that there's a step coming up which will do this automagically or if there's some other script (this setup file) to be run.


 * I, too, have questions about this step.


 * I have a MySQL server and an Apache server, running on two separate computers. Now I would like to install the MediaWiki software on the Apache server.  I do not want to install MySQL on the same machine; I want MediaWiki to connect to my existing MySQL server.  I also do not want to allow the wiki software to use the MySQL username root (except possibly during the creation of the wiki database).


 * Can I configure MediaWiki (1.4.9) – before or during installation – to use a host different from localhost as its db server? How?
 * --Verdlanco\(talk) 13:52, 26 September 2005 (UTC)


 * Never mind – I think I found the answer in the configuration settings index.
 * I have added a line to the documentation in case someone else has the same questions as I had.

How to add an initial administrator user?
I created the database before running the install script. How can I add an administrator now? Either through the site or directly in the database? -- anon


 * I also had problems with the initial set up of the first administrator user. It's supposed to happen automatically, but for me something went wrong too. Could be there's a bug there, but maybe I just did something stupid.


 * Anyway I suppose the first tip would be to go to your 'Special:ListUsers' page, that's wiki URL/index.php?title=Special:Listusers  ...It should list your administrator user, with "(Bureaucrat, sysop)" by the name.


 * I had the problem that I was unable to login with that user. Requesting it to email the password is the first thing to try I suppose, but for me this was not working (don't think any email features are going to work for me). I got around this by making a temporary security loophole, modifying includes\SpecialUserLogin.php -- Harry Wood 10:14, 10 October 2005 (UTC)

question about problem with installing
Notice: I had a problem while installing. I filled in the form as desired and with the right database password but still got an error that the database password was wrong. The problem was the encoding the browser used (utf-8) and special characters in the password. After changing the encoding to ISO-8859-15 everything worked fine. (But I am not sure whether this is a problem of the browser, the server or the media wiki)

You might see:

"Sorry! The wiki is experiencing some technical difficulties, and cannot contact the database server." This isn't a particularly useful debug output and you might spent ages chasing your tail, but check your version of php and mysql. There is a basic incompatability between the php-4 and mysql-4. in terms of password authentication.The mysql client within php4 used an older method of encryption. The capability to use older style sql passwords exists via an "old_password" function, but that defeats the improved security. At present I haven't found a solution - other than moving to php-5 which I think is a little drastic. Surely this is a config setting?

As a workaround, after you get the above error log into mysql and reset the password created using the "old_password" function (Documented at http://dev.mysql.com/doc/mysql/en/old-client.html):

set password for wikiuser@'%' = OLD_PASSWORD('YOUR_PASSWORD'); set password for wikiuser@localhost = OLD_PASSWORD('YOUR_PASSWORD'); set password for wikiuser@localhost.localdomain = OLD_PASSWORD('YOUR_PASSWORD');

Re-run the web page and it should now work.

Questions about chmodding
Question - The LocalSettings.php file is created by the web server with a+w permissions. Is it a security risk to leave it writeable by all users, or even the web server?

Guess? - Mine was just created 644, maybe this was changed/fixed or specific to your os / apache setup?

I believe it is not a security risk. If the permission is not 644, for instance 600 or so, then the web server would not be able to read the wiki's configuration. (the webserver runs with the permission "other")


 * If you move it instead of copying it, then it will be writable by the web server. It may indeed be safer, especially on a multiuser server without safe mode restrictions, to make it owned and writable only by yourself. It must however be readable by the web server or the system doesn't work. --brion 03:52, 27 Feb 2005 (UTC)

Question: I just installed the newest stable Mediawiki. After moving LocalSettings.php to the root directory its permissions is 666. This permissions is probably risky but in the article it is not mentioned what permissions LocalSettings.php should have. Does anyone know?
 * ...and does anyone know how to change these permissions?

Question: Do you mind: You will need to set the permissions (chmod) the config directory to 600 (instead of 0600) ? --AmbroiseIngold 09:43, 8 Apr 2005 (UTC)

Historically, the chmod command used octal notation, so the leading 0 was significant. More recent versions of chmod will do the right thing without the leading 0. Actually, what he probably should have written instead was 0700. If you use 0600, the directory is not executable to the owner. 0700 is read+write+execute for owner. For directories this means that the owner is able to change current dir to it.


 * Also, nowadays, if you use a non-zero digit for the first of four, that controls the SUID/SGID/sticky settings. I don't know just how it worked back in the all-octal days, if they needed a fifth digit in there when they were setting S*ID bits or what. But the extra isn't purely a useless holdover these days. -- John Owens 20:54, 2005 August 1 (UTC)

It's still producing 0666/rw-rw-rw for me in 1.5beta4, so given others' statements that they got 644, I'd imagine it probably depends purely on your umask setting for the user your webserver runs as. And I do feel that there should be a note to check its permissions right alongside the note to move LocalSettings.php into the wiki root. --John Owens 20:54, 2005 August 1 (UTC)


 * My LocalSettings.php is also 666 (ooh, how devilish!); does anyone know how I can change this? Say's I'm not allowed like...

I found a nice way round this:

cp LocalSettings.php LocalSettings1.php

touch LocalSettings.php

chmod 644 LocalSettings.php

more LocalSettings1.php &gt; LocalSettings.php

more LocalSettings.php    (to check all is well)

rm LocalSettings1.php

What should the permissions be on the other folders? There are currently 755, but are then accessible online. Should I create a .htaccess file? Thanks!

Index.php
I've uploaded my files, created my MySQL database, and chmoded the config directory... then I got to www.mysite.com/wiki and there's a link that forwards me to the config directory.

Which then tells me that index.php is not found, even though I'm looking directly at it should I tab over to my FTP client.

Is this a common problem? Is there just something I did wrong in the installation? Or something set-up wrong in general?

reply
Your host may be using php4 by default. I am trying to install this on a 1and1 account (without luck yet) and had to add an .htaccess file specifying to use php5. This solved my problem. See http://faq.1and1.com//scripting_languages_supported/php/9.html

I`m receive this warning during installing Wiki & then Thumb`s don't created
Warning: shell_exec has been disabled for security reasons in /config/index.php on line 1320

Hosting support service advice use GD library, how make instalation or configuration Wiki to use GD?

Or repair automatic Thunbnail creation using comand?

$wgUseImageMagick = false; file: includes/image.php find (it is around line:1065 and line:1052): $conv = shell_exec( $cmd ); change with: $conv = exec( $cmd );
 * To use PHP's GD library, add following line to LocalSettings.php:
 * If you change shell_exec command used in Mediawiki with exec command, you don't get any warnings and can able to create thumbs with ImageMagick:

Most instructions assume that you do your own hosting
...and do not address issues when someone else is hosting. For example, how do you back up mysql through phpAdmin?

Using diff3 on Windows/IIS
I managed to get a working installation of MediaWiki (1.5.3) on my webserver, but I am unable to get the diff3 utility to work properly. I have set the path to the GnuWin32 utility in LocalSettings.php, and played around with permissions in that directory to no avail. I continue to get these errors on the edit conflict page: Warning: popen(C:\Program Files\GnuWin32\bin\diff3.exe -a --overlap-only "C:\WINDOWS\TEMP\mer1E.tmp" "C:\WINDOWS\TEMP\mer1D.tmp" "C:\WINDOWS\TEMP\mer1F.tmp",r) [function.popen]: No error in F:\wiki\mediawiki\includes\GlobalFunctions.php on line 812

Any ideas?

Works ok with me, this line in LocalSettings.php: $wgDiff3 = 'C:\www\GnuWin32\bin\diff3.exe';

And thats where I downloaded.

I did set permission for diff3.exe to EVERYONE, since for some reason my computer doesn't have the ISUR_XXX and the WUSR_XXX accounts. Maybe because its a company machine. But diff then works.

?Recommended Hosts?
I am currently running MediaWiki on a webserver host that does not support ImageMagik, dvips, make, gmake... I am desperate to enable texvc. Can anybody recommend a good webhost for MediaWiki with all this support. Further, it would be nice to synchronize my online database with that on my home computer (using something like Webyog). Do any hosts allow this? Many thanks, Joejk2 15:15, 6 January 2006 (UTC)

How can I install MediaWiki on my PC?
I downloaded MediaWiki, PHP, MySQL, etc, and i want to istall it on my personal computer so that only people on my network at home can use it. How can i do that? 84.109.89.71 00:35, 10 January 2006 (UTC)

Not to be flip - but just read & follow the instructions! Installing on your home pc is not really different from a server install - its just that the server is in your house not at some remote location! Last nite I installed all this to my daughter's laptop (Win XP). I DID find a bug in the specific combination of Apache 2.2 with PHP 5. The cure is a ZIP file containing the relinked php5apache2.dll file. THEN I also found, on the mysql site, a replacement extension file - php_mysql.dll + libmysql.dll. AND you need the file vcredist_x86.exe from the Microsoft web site. Sorry but I can't remember the HERO who figured this out and made a note somehere in my internet travels late last nite... But aside from this version specific glitch, this should all take just a half hour or so... Good luck & enjoy!! Mark --24.195.14.18 23:02, 11 July 2006 (UTC)

Terrible TERRIBLE FAQ
This Installation guide needs a TOTAL rewrite as it assumes developer knowledge of a fairly high level.

We need a guide for normal people who know how to upload files, what their server adress is and all that but havn't got a clue what to do when it says "If this doesnt work just create a MySQL DB and make a local user on it". WTF???

Please PLEASE rewrite this guide so a non-developer can understand it. It doesnt take dev- knowledge to admin a small wiki so it shouldnt take dev-knowledge to install it in the first place.

I agree whole heartedly. This is a good program that I have seen in practice on other sites but I cannot troubleshoot the problems that this installation guide does not address or address poorly/too advancedly. I really agree with the poster of this message. Raj O Mac 06:27, 10 February 2007 (UTC)

Installer not working
I upolad all the files, I am presented the "You'll have to set the wiki up first!" link, then "INTERNAL SERVER ERROR" when I try to access the "config/index.php" page.

My site is hosted by aruba.it ... anyone has already installed mediawiki on aruba?

Thx

Memory limit
Hi, on my hosting there is PHP limit set to 6MB. Installer fails. Is it at least possible to run wiki under these conditions? If so, how do I manually set up the wiki.

MediaWiki has a problem

Sorry! This site is experiencing technical difficulties.Try waiting a few minutes and reloading.(Can't contact the database server: )

What is the problem?

After moving localsettings - Internal Server Error
In short I am able to successfully install Wikimedia without problems. I then move the 'localsettings' file into the main directory and the problems occur. Once this is done I get a '500 Internal Server' error.

As far as I can see the URL redirects from /wiki to /wiki/index.php?title=Main_Page so it should be working. The index.php and localsettings.php files have CHMOD 755. I'm using the latest version of the software and PHP version 5.0.5.

Hopefully someone can point me in the right direction, cheers. Brollachan 09:24, 25 April 2006 (UTC)


 * Try setting the LocalSettings.php permissions to 777; some hosts seem to need that, despite the security risk. // Pathoschild (talk/map) 11:48, 25 April 2006 (UTC)
 * Tried without sucess. As far as I can tell the server doesn't work if the file is CHMOD 777, as when index.php was 777 it wouldn't redirect the url to the main page. Probably worth mentioning that the internal server error page also states "Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request." on its last line. Brollachan 12:14, 25 April 2006 (UTC)
 * According to my webhosts the server is a 64bit linux machine and you need to talk to the autheoprs of your scripts if there is a problem as they should have a updated code for 64 bit. Hope this new bit of infor may be of some use, as I'd really like to get it working. Brollachan 18:47, 7 May 2006 (UTC)

Web and Google access to subdirectories
Once installed, how to make the subdirectories unaccessible to the web viewers and google indexing? Thanks, Justin

Lighttpd
I'm currently running the software on my lighttpd server, and it runs fine. I'm only running 1.5.6, I will upgrade tonight or tomorrow and reply with my results, but I don't see why it can't run the newest version. The main point of this is I'm asking/requesting that it gets added to the Prerequisites space.

Update: The newest version as of writing this (1.6.7) is installed and working on my lighttpd server.

To complete the installation, move config/LocalSettings.php to the parent directory.
To complete the installation, move config/LocalSettings.php to the parent directory. Uh! I tried to copy and move it to all possible places and it still don't change.... Do i need to have the index.php in the config file too?

Tried it in:

/public_html /public_html/config /public_html/wiki

edit: I tried it in /public_html/wiki/mediawiki-1.6.7. And then it worked, but the only thing who appears is this: �‹�

for my installations (at least) I simply moved the LocalSettings.php from from the directory it starts in (which is inside /config) to the SAME directory as the one holding the /config directory. For example, if the directory structure is: c:\wiki\config\LocalSettings.php then move it to: c:\wiki\LocalSettings.php - see - just up one level...

hope that helps.. Mark --24.195.14.18 23:06, 11 July 2006 (UTC)

Bad description concerning "Run the installation script"
I urgently recommend rewriting of that section. It says: "Use your browser to visit the wiki directory on your webserver to run the installation script. If you installed into public_html/wiki, this will probably be something similar to  http://www.yourdomain.com/wiki . Depending on how you uploaded the files, you may need to visit  http://www.yourdomain.com/wiki/config  instead."

This is quite irritating (if not wrong) and incomplete.
 * First of all, it is not even mentioned, which file the installation script actually is. You can't expect a newbie to just know that. Thus, it has to be mentioned that it is the index.php in config-subdirectory.
 * Additionally, not every website is by default configured to use "index.php" as default document - especially not on windows servers. In that cases,  http://www.yourdomain.com/wiki </tt> as well as  http://www.yourdomain.com/wiki/config </tt> brings you nowhere.
 * If you installed into public_html/wiki,  http://www.yourdomain.com/wiki </tt> will most probably not run the installation script, as this is located in the config subdirectory. So either the correct URL will most probably be  http://www.yourdomain.com/w--~iki/config(/index.php) </tt> or  http://www.yourdomain.com/config(/index.php) </tt> if the website points directly to the wiki root directory

As to "knowing" that the script to be run is index.php - no, actually you DO NOT need to know that! Because if the server is properly set up, pointing to the /wiki/config directory will AUTOMATICALLY cause that file to load/run! Because part of the PHP installation is to tell the server to do that... like it normally would for index.htm or index.html... If your server's PHP installation uses something other than index.php (let's say START.HERE instead) then you'd need to modify the wiki's files/structure accordingly - renaming index.php (which is actually standard I think) to START.HERE - which would be a maintenance issue I should think...

Your last point is not completely true tho - on my LINUX box I think the wiki automatically pushed me from wiki to wiki/config... on my windows pc, I manually had to go to /config to run it...

enjoy! Mark

User Names
Having finally got Apache and MySQL running reasonably reliably, I'm at the point of entering initial setup details for my new wiki database. I had the idea that the installation script would create an initial user for me, and that that was why it was asking me to specify passwords and usernames at this stage. Unfortunately it seems to want these details already defined, and frankly I'm at a loss how to do it. If someone has explained this already in the text above I do apologise - but I'd be very grateful if someone could give me it step-by-step. Thank you - Fimbulvetr 13:05, 21 July 2006 (UTC)

Version 1.6.2 problems I encountered (ENGINE/TYPE and KEY TOO LONG)
I hope this is the correct place. I don't know whether these apply to the current version, or whether this is the correct place.

1. In maintenance/tables.sql (the mysql4 ones) it says ENGINE=InnoDB in several places. Because I'm using an old version of mysql I had to change each ENGINE= to the older TYPE= for it to work.

2. In the same file it gave "key too long" error for the job table. I think this is because the utf-8 thing uses 3 bytes per character so it goes over the limit. Anyway, doing a bit of maths, it seemed to work when I changed the relevant line to KEY (job_cmd(248), job_namespace, job_title(248)).

Hope this helps. Jonathan1 20:21, 23 August 2006 (UTC)

Languages folder
Can I remove some files in Languages folder? Especially MessagesAf.php, MessagesAr.php ... MessagesZh_tw.php. I think I need only files for (one!) my language (cs) and perhaps english files, too. Thanks. J. Cerny

Not recognizing MySQL
When I enter my info at the localhost/wiki/config/index.php page, it only lists postgresql as a possible db. I have mysql installed, so why isn't it recognized? Also, the installation won't even work with the postgresql db on my localhost server. (In other words, as my db server, I put "localhost", and it says it can't connect. The postmaster is running.) What am I doing wrong? Thanks, ElAmericano 02:00, 3 September 2006 (UTC)

Well, it's still not recognizing that I have mysql, but I'm at least getting past it not connecting to the postgresql db. Now I get the following:

Installation error message
When I attempt to install v1.6.8, I get the following error: Parse error: parse error, unexpected '.' in /home/zippee/descendantsofjulia-www/wiki/includes/OutputPage.php on line 957

I am using a hosted server that passes all of the installation requirements when the install script runs. I think this must be a naming convention problem, but I'm not sure. Any ideas would be greatly appreciated. Thanks!

It is now fixed! In the spirit of helping others, I don't know the specific fix, but what I did was go ahead and delete my folder on the server, and then recopied the software to a new folder on my hosted server. It is now working. Obviously, this error must be generated by the installation script when there are missing files.

Installation Timeout
Hey y'all...

I'm trying to install mediawiki on Awardspace.com (a server I have read decent reviews about, including mention of running mediawiki). I hit the initial configuration page, enter all the info, then it goes away to do its thing. Problem is, the server times out...

Error Code 1460: timeout Background: The gateway could not receive a timely response from the website you are trying to access, a DNS server, or another gateway server. This might indicate that the network is congested or that the website is experiencing technical difficulties.

I've tried this several times over the last 6 days...same issue, so not congestion, reasonably sure its not tech difficulties...

I'm wondering if it could be due to the line in the Environment check:

PHP's memory_limit is 16M. If this is too low, installation may fail! Attempting to raise limit to 20M... ok

But I could be talking rubbish...I just don't know.

Anyone have any ideas ay all? I would be really really grateful...if it's not against policy, my email address is: [mailto:eclective@gmail.com eclective@gmail.com]

Failed to open stream
Sorry if this has already been asked, but I didn't see anything that addressed my issue, so...

I'm attempting to install MediaWiki 1.6.8 on a server running PHP 4.4.2 and MySQL 4.1.21. I get this error message when attempting to do so:

Warning: main(install-utils.inc): failed to open stream: No such file or directory in /home/www/wiki.thecrimsondawn.org/config/index.php on line 43

Fatal error: main: Failed opening required 'install-utils.inc' (include_path='.:/home/www/wiki.thecrimsondawn.org:/home/www/wiki.thecrimsondawn.org/includes:/home/www/wiki.thecrimsondawn.org/languages') in /home/www/wiki.thecrimsondawn.org/config/index.php on line 43

I am wondering whether it has something to do with the fact that I'm attempting to install it to a subdomain. I also have a feeling it's getting the path wrong as the path to my wiki directory is /home/public_html/wiki.

I don't really know PHP, but if there's a line that needs to be changed somewhere in config/index.php or something, I can do that.

I also made sure that the config directory is writeable, so it isn't that. -- Amber 17:30, 6 October 2006 (UTC)

Explanation of Caching options
I've used MW before and now going for a more serious site! ;) I've never changed any caching options (or used caching software) and I think it would be sueful to have an explanation of the ways to speed up the MW process that we can do. On the installation page it says "Couldn't find Turck MMCache, eAccelerator or APC. Object caching functions cannot be used." (And nicely gives a link to their project pages) but there's nowhere easy that explains the advantages and disadvantags of using them with MW. Just my 2 pence --172.200.182.161 16:35, 17 October 2006 (UTC)

Installion guide does not explain how to specify turck mmcache server/port
I have installed turck mmcache but what do input for server and port? I tried localhost:80 with no success. "Shared memory caching: Memcached servers: Didn't get correct memcached response from localhost:80"

Server/Port Problem
I have eAccelerator installed, but MW fails to recognise it. As far as I can tell, eAccelerator does not use a port. It is frustrating that a good wiki engine (MW) comes with so lousy information and without a decent documentation. phom 2007-2-7

Added passage about missing table prefix
My shared host is pair.com. This was the output of a successful install after I applied the prefix hack. My small wiki farm employed many symlinks. My default config page did not present the database table prefix. That's now explained on the main page.

My box is a Windows XP Professional SP2, running Apache 2.0.54, MySQL 5.0.27 and PHP 5.13.

Other applications requiring PHP or MySQL work properly, so the setup of these pieces of software should be OK. However, the installer keeps complaining about the problem about creating a record in a table with a default value...

Any ideas? Is MediaWiki ready for MySQL 5 or should I use MySQL 4?

Jose.

Well, it's myself again, answering my own question...

I dediced to google for "BLOB/TEXT column ... can't have a default value" and found this:

http://bugs.mysql.com/bug.php?id=19498

This page states that MySQL 5.0.18 had a bug: it allowed a BLOB/TEXT, NOT NULL field to have a '' default value. This is exactly what the installer is trying to do, create a field with these characteristics.

I have MySQL 5.0.27 and looks like that bug was corrected, so the attempt to create a BLOB/TEXT, NOT NULL field with a '' default value is simply refused by the db server.

Bad luck. At least the files /maintenance/tables.sql and /maintenance/mysql5/tables.sql need to be patched to avoid this.

Jose.

changed LocalSettings.php does not work
The installation was succesfull. After enabling image uploads, and thus only changing false into true, de LocalSettings.php doesn't work anymore.

Avonts 16:11, 14 January 2007 (UTC)
 * I found what the problem is thanks to our friends of the Mediawiki-mailinglist. I was editing the LocalSettings.php-file with Windows Notepad. When saving the file, Notepad inserted an invisible character at the beginning of UTF-8 files (the "byte order mark" or BOM).
 * The BOM character, unfortunately, breaks PHP files because it gets sent to output before any of the code is run. So it's necessary to save the file as UTF-8 _without_ BOM, if you have the option available. Now I'm using jEdit.

Most webserver hosts will NOT give their clients ssh access to their server OR give them the root pass to the mysql database stuff.PLEASE write a install guide that takes into account the following: If anything the code NEEDS to be rewriten to take into account the above.
 * cpanel
 * lack of access to ssh or the actual server itself
 * lack of linux experence

Config Directory Unwritable
I really have no idea what this means...how does one change the owner to apache and where does that code go?


 * Config directory unwritable: If you have changed the permissions for the config directory and still get an unwritable error try changing the owner to apache.

* chown -R apache:apache /var/www/html/mediawiki/*

Cant install the WIKI
Hello I loaded the Wiki up and then I opened the index.html, but i always come to https://www.configtools.de/xml/config;jsessionid=39947F541243361789908C60311E900D.TC164b!!!!!!!

WHY???!!!!!! ITS FUCKING WRONG!!! I CANT INSTALL IT! WHAT SHOULD I TYPE INTO configtools.de ??!??!?!

Warning: $wgSecretKey key is insecure, generated with mt_rand. Consider changing it manually.
This message seems to appear during every installation.

I have two problems with this message:
 * 1) What is the actual security risk? I found out that mt_rand is based on the Mersenne Twister, and that this random number generator is insecure because it is possible to predict the all random values from a short sequence (about 600) of generated random numbers. There seem to be calls to mt_rand at many locations in the code. Therefore: How would an attack look like that exploits this vulnerability, i.e. gets a sequence of consecutive random values, and what is the benefit for the attacker?
 * 2) What can I do to avoid the security risk? Assuming that the security threat is real, what I have to do to change $wgSecretKey manually?

Failed opening required './LocalSettings.php'
I get the following error:


 * Warning: require_once(./LocalSettings.php) [function.require-once]: failed to open stream: Permission denied in /home/plantsa/public_html/includes/WebStart.php on line 86


 * Fatal error: require_once [function.require]: Failed opening required './LocalSettings.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/plantsa/public_html/includes/WebStart.php on line 86

It's a fresh install, the whole process went smoothly, then I made my changes in localsettings, and went to run it, and get this error. I don't even know what to begin looking at. The only one thing not really in place yet is that the domain name I plan to use is not up yet. But when I try running it using the IP number I get this error. Is that the cause or is there something else I should look at. The path it is looking for the file at seems nonsensical to me. Thanks! Raffi

-- I had the same problem ... turned out that I needed to change permission for LocalSettings.php to "chown www LocalSettings.php"

Installation fails - Wiki 1.7.1 under Kubuntu-6.06 using Postgres-8.1
The description is fine except the following update line.

echo 'update pg_ts_cfg set locale=`$LANG` where ts_name=`default` and prs_name=`default`'| psql wikidb

if the line 'update' in the above box does not work try the following in the psql shell:

psql wikidb update pg_ts_cfg set locale = current_setting('lc_collate') where ts_name = 'default'; \q

I found that in http://www.postgresqlforums.com/forums/viewtopic.php?f=35&p=178 after googling "tsearch postgres wiki"
