MySql: ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (111)

Tried several ways and finally solved it through the following way

sudo gksu gedit /etc/mysql/my.cnf
modified

#bind-address = 127.0.0.1

to

bind-address = localhost

or
if your MySQL server IP is 65.55.55.2 then entire block should be look like as follows:
bind-address = 65.55.55.2

and restarted

sudo /etc/init.d/mysql restart
it worked
