I have trouble with mysql on linux

I am having error after entering password for mysql on linux mint.
Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2).

I went to the stackoverflow and read about above error but unable to understand what it is being said.
Any one please explain me how to fix it in easy steps .Before this error i had been able to use Mysql database comfortably.

click me!

What that guy is suggesting is pretty simple, and if you don’t get it working, the easiest solution would be to uninstall your current MQSL and install it again from what I have read.
