Manual:Config script/zh

An English native speaker may translate the German version that is up-to-date.

Once you have uploaded/installed MediaWiki on web server, the first thing you need to do is complete the basic setup by running the supplied configuration script. This script allows you to tell MediaWiki the information it needs in order to get the wiki up and running.

Opening the MediaWiki installation form
In the following examples, it is assumed that your website is located at  which is physically located on your server at. You will need to adjust the examples to use the appropriate locations for your situation.


 * 1) Use your web browser to browse to the main wiki page.  This is   inside the web-accessible folder that you installed MediaWiki into, and is typically   (e.g. , assuming you installed MediaWiki to  ). (You should not have used   if you want to use it as a Short URL).
 * 2) You will see the version of MediaWiki installed and a link to "Please set up the wiki first." Click on the link to begin the configuration script. For reference (in case you want to go there directly), this is located in the wiki's   directory (so using the example above you would go to  ).
 * 3) If the script spots any configuration errors then it will not allow you to continue. See below for details about the error messages you might encounter, and what to do if you do.
 * 4) If all the tests pass, you will be presented with a form to fill in the information that MediaWiki now requires.
 * 1) If all the tests pass, you will be presented with a form to fill in the information that MediaWiki now requires.

Using the config script
Follow the instructions on the form to fill in the required entries (refer to the following table if you're uncertain what to enter) and after that click on the "Install MediaWiki!" button. The script will now populate the database and write a configuration file.

After the setup script has finished running successfully, a file called  is created in the mw-config (config for older versions) directory. This file contains all the information needed by MediaWiki to run. Since it stores the specified database user's password in plain text, it is strongly suggested that you create a wiki specific database account (i.e. not root). (see Database username in the table below)


 * 1) Move this file to the main wiki directory (if you installed MediaWiki to /home/example/web/w, move it there).
 * 2) Set stringent permissions on the LocalSettings.php file.
 * 3) * Set chmod 600 and chown (Owner read and write, no other permissions).

Once you have done the above, your wiki should be ready to use. Browse to the address you installed it to (in our example http://www.example.com/w/index.php ) and start editing!

Installation errors
When you run the config script it makes various checks of your system, and tells you if there are any problems.
 * After installation if your server is redirecting to a non-existant url try and go back and hit stop before the page redirects and grab Localsettings.php.

Add the following line after $wgSitename:


 * Parse error: parse error, expecting `T_STRING' in [...]\wiki\includes\Namespace.php on line 52
 * Make sure you have the appropriate version of PHP for the version of MediaWiki you are installing.
 * Attempting to connect to database server as wikiuser...failed with error [2004] Can't create TCP/IP socket (10106).
 * Often found in the internet that you should turn on named pipes in the MySQL configuration, but this did not help me (this appeared under Win2000 with MySQL 5.0)
 * "Warning: main [function.main]: open_basedir restriction in effect. File(/convertLinks.inc) is not within the allowed path(s):"
 * Apparently the include path sometimes needs to be set. Put [ php_value include_path '/var/www/vhosts/yourhost.com/httpdocs/pathtowiki'  ] in you .htaccess file.
 * (MediaWiki 1.10.1&1.11.2) After 'Running the script' 1. The text is: 'Setup has completed, your wiki is configured.' Selecting 'your wiki' opens a new screen with the address: http://localhost:8080/mediawiki/index.php and the error '404: The page cannot be found'.
 * Path to php5isapi.dll is incorrect. In IIS manager go to web sites right click on web site go to properties then go to home directory tab and then click on configure find php in the list and then click edit and fix the path (C:\progra~1\php\php5is~1) Should be ("C:\program files\php\php5isapi.dll")
 * Warning: getrusage is not supported in this PHP build
 * We do function_exists checks for getrusage, so if you see this error message, probably means you should file a bug.

 * If there is MySQL 'DB connection refused' error, it is possible the default port in Apache's PHP file ('php.ini') is incorrect.


 * Your system has a combination of PHP and libxml2 versions which is buggy and can cause hidden data corruption in MediaWiki and other web apps. Upgrade to PHP 5.2.9 or later and libxml2 2.7.3 or later! ABORTING (http://bugs.php.net/bug.php?id=45996 for details).
 * Well as the error says, either upgrade one, or downgrade one.

Warning: $wgSecretKey key is insecure, generated with mt_rand. Consider changing it manually.
 * What about the $wgSecretKey e.g.

a) what is this and b) what is the solution ?

Answer: It means your system doesn't support /dev/urandom so the key was generated with mt_rand. You can manually edit the wgProxyKey field in LocalSettings.php.
