When you encounter an error such as
Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /path/to/geeklog/system/databases/mysql.class.php on line 112then this means just what the error message says: Geeklog could not establish a connection to the MySQL server.
Cannnot connect to DB server
$_DB_host(in your db-config.php) is not correct.
$_DB_hostcontains the name of your MySQL server. And if that doesn't help, ensure that the MySQL server is really running (which, unless it's your own server, means that you should be talking to your hosting service).
$_DB_hostsetting is correct, check that the socket is correct, i.e. that MySQL is using the socket that PHP expects. Compare the "socket" entry in MySQL's my.cnf config file with the output you get from phpinfo() (you can use the /admin/install/info.php file that ships with Geeklog to get the phpinfo() output). This usually only happens when you installed either PHP or MySQL yourself.
