Making the wiki fast


See <tvar|1></> ''

Setting administrative rights
MediaWiki is a permissions-based wiki system. That means that users will only be able to perform the actions they are allowed to do.

As declaring permissions individually for every user would be tedious and impractical, several <tvar|rights></> are pre-defined in MediaWiki.

You are also allowed to declare new user groups, as your needs require.

Individual contents>Special:MyLanguage/Extension:Contents</>|extensions may also require creating new user rights.

Regardless of how they are created, user groups are fully customizable, by modifying the <tvar|GroupPermissions></> associative array in your <tvar|LocalSettings></> file.



Sysop (Administrator)
The most common use. A user marked as 'sysop' can delete and undelete pages, block and unblock IPs and use a shortcut revert-to-previous-contributor's-revision feature in contribs, see <tvar|m-admin></> for more information.

Bureaucrat
Users in this group can change user rights through <tvar|spec-ur>Special:UserRights</>.

Bot
A registered bot account. Edits by an account with this set will not appear by default in Recent changes; this is intended for mass imports of data without flooding human edits from view. (Add <tvar|hidebots>&hidebots=0</> to list changes made by bots e.g. [<tvar|1>http://en.wikipedia.org/w/wiki.phtml?title=Special:Recentchanges&hidebots=0</> like this])

Installing extensions


See <tvar|1></> ''

Extensions are compilations of PHP code that add new features or enhance functionality of the main MediaWiki core.

Localisation


See <tvar|1></> ''

If you simply want to change the language of a wiki on a per-user basis, this can be done via <tvar|spec-pref>Special:Preferences</>. If you selected the wrong language when setting up the wiki simply change the $wgLanguageCode in <tvar|LocalSettings></>.

Maintenance scripts


See <tvar|1></> ''

MediaWiki has some maintenance script to help doing administrative tasks.

Update MediaWiki


See <tvar|1></> ''

Back up


See <tvar|1></> ''

It is important to make regular backups of the data in your wiki. This includes the database, uploaded files and extensions.

Importing a database dump


See <tvar|1></> ''

If you want a local copy of a Wikimedia wiki, see the overview at <tvar|meta-dd>meta:Data dumps</> and the [<tvar|d>http://download.wikipedia.org/</> download site].

Converting (importing) existing content


See <tvar|1></> ''

Some scripts exist to import data from other wiki engines.

On-wiki customizations


See <tvar|1></> ''

Much of the appearance and messaging of MediaWiki is determined by messages that administrators can edit like regular wiki pages.
