MediaWiki database layout

MariaDB/zh

The MariaDB database engine is one of the most commonly-used database backends for MediaWiki. Since MariaDB is the relational database management system used by the Wikimedia Foundation websites, it is well-supported in MediaWiki.

See Compatibility#Database for a list of supported versions.

Connecting to MariaDB

If using a MariaDB 10.3 or earlier:

 mysql -u wikiuser -p my_wiki

将wikiuser和my_wiki更改为您的Wiki的用户名和数据库名称（$wgDBuser 和$wgDBname ）。出现提示时，输入密码。

Installation

更多信息请参见Manual:Installing MediaWiki#Create a database

If MariaDB is installed, the installation script can create a database for you. Just supply the script with your RDBMS root password (by default, blank).

警告：

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

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

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.
