It looks like mysql is not running or the credentials are wrong. Was mysql pre-installed on this server or did you use a minimal install?
Lets try to start mysql:

hi
tnx
that was correct, the mysql was stoped...
i fixed it with these commands:

root@ns1:/root#
rm -rf /var/lib/mysql/mysql.sock
root@ns1:/root#
service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
root@ns1:/root#

There must have been an unclean shutdown of the box or mysqld service if the socket still existed when it was stopped. Is the login working now?
