Issue with MySql Server connection

Question

I was able to connect to MySQL server a few days back but since today I am getting an error while connecting through the command line. Below is the error from the command line:

[user@localhost ~]$ sudo mysql -u root -p
[sudo] password for user: 
Enter password: 
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)

Answer 1

Try to restart the mysqld server and then login:

sudo service mysqld restart
mysql -u root -p

If that doesn't not work then try the following:

sudo pkill mysql
sudo pkill mysqld
restart mysql
sudo service mysql restart

now you should be able to log in

mysql -u root -p
