Media Wiki Configuration

System Configuration

OSGeo uses a Mediawiki instance as our main wiki ( The configuration of the mediawiki instance is documented here (in Trac) instead of in the regular wiki so that we have a decent chance of seeing this info if the wiki is down.

  • Primary Maintainer: Martin Spott (Martin.Spott at (osgeo userid: "martin").
  • Host: "osgeo2" - the secondary system at Peer1 (ssh to or
  • Configuration Location: /var/www/wiki_osgeo

It appears we also host the fossgis wiki (/var/www/wiki_fossgis).

User Map Project

To maintain a Usermap of the OSGeo wiki, a UserLocalization Extension has been integrated into the wiki by Christian Willmes (c.willmes at (user: christian): here

Installation of the Mediawiki Extension:

  • installation of a Postgres/PostGIS on the server
  • integration of the Extension into the Wiki

More information about the UserLocalization Extension can be found at:

Wiki Down Recovery

If the wiki stops operating it may be helpful to restart apache, and/or mysql.


$ sudo /etc/init.d/httpd restart
$ sudo /etc/init.d/mysql restart


To keep anonymous users from editing the wiki, add/change in LocalSettings.php:

$wgGroupPermissions['*']['edit'] = false;
$wgGroupPermissions['user']['edit'] = true;

This will prevent anonymous users (users who aren't logged in) from editing the wiki. See also MW FAQ
