Hey there.

Problem is in your post

Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (11)

You need to check if your MySQL server runs, and if it runs - seemed in other place than it was before installation. So you will need to edit path to mysql in inc/header.inc.php file
