How to solve Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’

Hi Friends today I got an error when using mysql I was not able to login as a root user . Actually I have used mysql long before and now when I try to relogin it showed me some error like this ” Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ ” . I dont know the exact reason for why it had happened . But I was able to solve through web research on this query . The steps I had followed are :-

 

(1) To check the my.cnf file is correctly configured I used this command : –

 

socket=/var/lib/mysql/mysql.sock
 
(2) To check if the mysql runs with the commands we can use this : -
 
mysqladmin -u root -p status
 
 (3) If this had worked then u have to change the access to your mysql folder . And this can done by following this command :-
 
sudo chmod -R 777/var/lib/mysql/


By  FOLLOWING THIS STEP I WAS ABLE TO SOLVE MY PROBLEM .
