MediaWiki: Upgrading

BACKUP FIRST! Manual:Backing up a wiki
You can easily create a dump file(export/backup) of a database using the phpMyAdmin tool.
  • Consider making the Wiki read-only before creating the backup - see Manual:$wgReadOnly. This makes sure all parts of your backup are consistent (some of your installed extensions may write data nonetheless).
Developer hub
Sysadmin hub
From the command line, or an SSH shell or similar, change to the maintenance directory and execute the update script: $ php update.php Use this command instead: /usr/local/php53/bin/php update.php

Read-Only Mode

The following two examples show the $wgReadOnly setting to add to your LocalSettings.php file to lock the database while you upgrade.

$wgReadOnly = 'This wiki is currently being upgraded to a newer software version.';
$wgReadOnly = "We are upgrading MediaWiki, please be patient. This wiki will be back in a few hours.";

Using Git

Git downloads

You can download code directly via Git from the MediaWiki source code repository (browse code) or download a snapshot. To get the latest version of an extension, for instance, just clone the git master.

For example, if you have shell access to your server, you may do this to download the Validator extension:

cd extensions
git clone
