What do I need to add to config.php

[محروم.كوم]

The only basic problem right now, is the config.php.
The settings I need to know about are these:
$config['Database']['dbname']
$config['MasterServer']['username']
$config['MasterServer']['password']


I get a repetitive error, and I've been trying to fix it all day. __DEFINE_LIKE_SHARE__
