MySQL Database Authentication Problem

 * MediaWiki: 1.12.0
 * PHP: 5.2.4
 * MySQL: 5.0.24a
 * URL: Company Intranet

In the Database Config section of installation, MediaWiki asks for the MySQL database name, username, and password.

I provide all of this information, but then I click the install button, I keep getting an error telling me to check the username and password. I don't get it. I followed installation instructions explicitly.

My MySQL commands are as follows: mysqladmin -u root -p create wikidb mysql -u root -p -e "GRANT ALL PRIVILEGES ON wikidb.* TO wikiuser IDENTIFIED BY 'wiki_password'" mysql -u root -p -e "SET PASSWORD FOR wikiuser = OLD_PASSWORD('wiki_password')" mysql -u root -p -e "FLUSH PRIVILEGES" Where I've changed "wikiuser" and "wiki_password" to something more appropriate. The syntax is fine, and no typos exist. I enter the information letter for letter in the Database Config section, and I still receive the password authentication error, and for the life of me, I cannot figure out why.

(RESOLVED) Upgrading to MW 1.12 without shell access

 * MediaWiki: 1.12.0
 * PHP: 5.1.6 (apache2filter)
 * MySQL: 4.1.20
 * URL: http://en.wiki-products.org

I updated the english version of our wiki from Version 1.11 to 1.12. Since we don't have shell access and "proc_open" is disabled by our hosting company, there was only "Alternative 2" left. So I copied all the files of the 1.12-version into the existing folders of our wiki. In that way old files were replaced but things like extensions and images were kept. Everything worked fine but after running the installation there was a fatal error when browsing the wiki. It said: "Fatal error: Call to undefined method ParserOptions::enableLimitReport in /home/httpd/vhosts/wiki-products.org/subdomains/en/httpdocs/includes/Article.php on line 3172". Since i didn't know what to make of that, I replaced "Article.php" with the old 1.11-version (lucky me, I did the back-up before) and now things seem to be running fine again. However, before I go on to upgrade the much larger (and more important) german version of our wiki, I would like to be sure, that this is the way to do it and that no further problems will emerge from this. Thanks for helping!

Once installed via ftp, I cannot continue configuration thru /config/index.php

 * MediaWiki: v1.12.0
 * PHP: PHP5
 * MySQL: 5.0.45
 * URL: http://wiki.php5.ict-idcollege.nl/

Hi,

I've installed MediaWiki on the Host (MediaWiki v1.12.0, PHP5, MySQL 5.0.45) of our school. 'Feel a bit a newb (which I am) but I do hope someone can help me with this. Anyway, I have installed via ftp, and can get to the index.php script in public_html by entering the above URL. All directories and scrips seem to be in place, I've set the file attributes of the /config folder to '777'.

I then get to see the initial index.php in the root. Once I click on the 'Please set up the wiki first.' link (which should redirect me to /config/index.php), I get to the 'Admin' login screen of my Host. Does this somehow ring a bell to you?

Thanks for your help in this. Erik Coolen, The Netherlands (ecoolen@ict-idcollege.nl) —82.169.26.209 11:22, 23 July 2008 (UTC)

I tried the upgrade of MediaWiki on my computer (before to do it on the real server). I used the Alternative #2, because I don't have shell access on the final server. Whatever, everything seems to go well (no error message during the "installation"), but the wiki is then unavailable : there is only one white page without errors. What's the problem then ? What can I do ? :-(

Hi all,

after upgrading my Mediawiki from 1.7.1 to 1.13 I can't use any HTML tags within the $wgSiteNotice variable. Only output I get is the raw text I inputted like

  

Localsettings.php is the same as before the update. I also updated the ParserFunctions extension but I'm not sure if my problem is connected to this extension. Did I forget to update any other files?

Any ideas? Every kind of help is appreciated!

Maziminke 15:32, 18 September 2008 (UTC)


 * $wgSiteNotice started taking wikitext instead of raw HTML in MediaWiki 1.9 "for consistency with editable MediaWiki:Sitenotice and MediaWiki:Anonnotice." It seems like it went back and forth between wikitext and HTML in past versions, so you could make a request on bugzilla if you think the current functionality isn't sufficient. —Emufarmers(T 23:20, 18 September 2008 (UTC)
 * Thanks for your help. This totally explains the behavior but is a bad message for me since it means recoding lots of code.
 * You mentioned to put a request to mediawiki's bugzilla system but do you think anyone will care for a single user's opinion? What do you think about implementing a switch to enable/disable HTML at $wgSiteNotice? Since both functionalities should be somehow implemented this would be a nice way to keep HTML working when updating!?
