This documentation covers the "new" MediaWiki package of 1.27+. Documentation for the "old" package which was unmaintained, had security issues, etc. can be found in the page history. Additionally, the old mediawiki-extensions* packages are no longer supported.
The new package is available in jessie-backports and will be included in stretch. Ubuntu Xenial and Trusty users can use a PPA by the same maintainer.
There are some more details at https://www.mediawiki.org/wiki/User:Legoktm/Packages.
Status
* pkg-mediawiki-devel list at Debian
*mediawiki-distributors list
Specified versions will be maintained as long-term supported (LTS), with support from MediaWiki developers and the distro packagers.
Debian changes to MediaWiki
We change a few things about MediaWiki to fit in with what Debian expects. Files can be found in the following places:
/usr/share/mediawiki - MediaWiki core files
/etc/mediawiki/LocalSettings.php - expected location of ?LocalSettings.php. You can also put other configuration files in this directory.
/var/lib/mediawiki - Main directory that the webserver will read from. Most core files from /usr/share/mediawiki are symlinked into this directory, and the ?LocalSettings.php file as well.
Installation
# apt install mediawiki
If you use Apache, MediaWiki will automatically be configured to serve it at http://localhost/mediawiki/. You can then visit that in your webbrowser, and go through MediaWiki's web installer.
If you use a different webserver, you'll need to manually configure it to use PHP to serve /var/lib/mediawiki.
The web installer will prompt you to download a ?LocalSettings.php file. You should save it to /etc/mediawiki/LocalSettings.php.
