Answer 1

There is another chance of you to get this particular error if you modify the max_connections in my.cnf file.

I also faced the same error which did not let me log in to MySQL server. In my case the problem was, I had to increase the max_connections size in

/etc/mysql/my.cnf

to

set-variable = max_connections = 5000

Due to this reason next day when I stared MySQL server it threw this error

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Removing the set-variable = max_connections = 5000 segment from my.conf file did the trick. After removing that particular segment following command was used. MySQL server started up and running like previously.

sudo /etc/init.d/mysql start
