The MySQL database engine is the most commonly-used database backend for MediaWiki. Since it is the relational database management system used by the Wikimedia Foundation wiki farm in its own websites, it is well-supported in MediaWiki.

Change wikiuser and wikidb to the username and database name for your wiki ($wgDBuser and $wgDBname). When prompted, enter your password.

Installation[edit | edit source]

Further information: Manual:Installing MediaWiki#Create a databaseManual:Installing MediaWiki#Create a database

Basically, if MySQL is installed, the installation script can create a database for you. Just supply the script with your mysql root password (by default blank).

Avertissement Avertissement: Leaving the MySQL root password blank can seriously compromise the security of the MediaWiki installation. You should modify the password if you haven't already.

Note Note : If you are installing MediaWiki on an ISP server, you might have to share a db with some other applications, which increases the risk of a conflict between database tables required by MediaWiki with pre-existing tables. To solve this problem you can instruct MediaWiki to use a table prefix, so that all tables of MediaWiki begin with this prefix. Alternatively, if your ISP allows, use different databases for each application that resides on the server.

Maintenance[edit | edit source]

Multiple maintenance scripts are included in the /maintenance/ directory of your MediaWiki installation. Some of these scripts are provided to refresh parts of the database as one-time operations.
