Cli config

This config is very difficult to handle. It is much easier to use the configuration with browser.

php maintenance/install.php

Configuration with browser

Make the folder /var/www/mediawiki served by httpd.

Then open the url : http://domain.com/mw-config

At the end, you have to download the LocalConfig.php file.

Put it in the folder /var/www/mediawiki.

BEWARE : if you have enabled the accelerated cache, you have to add this line to the LocalConfig.php file :

$wgSessionCacheType = CACHE_DB;

Note : if you don't, the wiki can work but it would be impossible to log in or to create any account.
