What is a Wikifarm?
Types of Wikifarms
The standard Debian MediaWiki structure
Recreating (moving over) your first MediaWiki instance
We'll assume you've followed the other tips in this wiki. Most notably, you've taken all steps described in the article on "how to Place MediaWiki inside a Virtual Host". The steps are simple
Move the Wiki configuration within /etc
Your Wiki config file will be /etc/mediawiki/LocalSettings.php, and the settings for Apache2 will be in /etc/mediawiki/apache.conf. We'll create a subdirectory under /etc/mediawiki that hosts the configuration of your Wiki. Suppose we name the subdirectory after the Wiki we're handling, in this example the SaruWiki. Furthermore, suppose that you also have an AdminSettings.php file. If you don't: no worries! Just skip the steps involved with that file!
cd /etc/mediawiki mkdir SaruWiki mv LocalSettings.php SaruWiki mv AdminSettings.php SaruWiki mv apache.conf Saruwiki
Note: make sure that after moving the files, the owner and permissions are the same. Moving a file while you are root has the effect of changing ownership to root. LocalSettings.php must be owned by user:group www-data:www-data in order for Apache2 to be able to read the file. The AdminSettings.php file, if it exists, must be owned by root:root and NOT be readable by world (permissions 600) because it should contain the MySQL "root" username and password, with which maintenance scripts can perform their tasks if you instruct them to (while you are root, of course). To keep the Wiki running, we're going to need to tell Apache2 where the two files went to. In this case:
- change the path to apache.conf in the Include statement in the site declaration (e.g. in /etc/apache2/sites-available/000-saruman.biz, change the Include line to
Include /etc/mediawiki/SaruWiki/apache.conf
- change the symlink in /var/lib/mediawiki that points to LocalSettings.php; and if you have one, change the AdminSettings.php symlink as well:
cd /var/lib/mediawiki unlink LocalSettings.php ln -s /etc/mediawiki/SaruWiki/LocalSettings.php unlink AdminSettings.php ln -s /etc/mediawiki/SaruWiki/AdminSettings.php
If you now restart Apache2, your Wiki will still work - but the two primary configuration files have moved over to a dedicated spot.
