One day I faced issue with mysql.sock file. I found Can’t connect to local MySQL error. I solved the issue with following commands.
[root@localhost ~]# mysqladmin -u root shutdown
mysqladmin: connect to server at ‘localhost’ failed
error: ‘Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)’
Check that mysqld is running and that the socket: ‘/var/lib/mysql/mysql.sock’ exists!
Using following command I checked the mysql directory.
[root@localhost ~]# ll /var/lib/mysql/
I did not find the mysql.sock file there.
[root@localhost ~]# cd /var/lib/mysql/
Created file in that location.
[root@localhost mysql]# touch mysql.sock
Gave the executabe permission the sock file.
[root@localhost mysql]# chmod +x mysql.sock
Changed the permission to mysql user
[root@localhost mysql]# chown mysql:mysql -R *
After that restarted the machine
[root@localhost mysql]# /etc/init.d/mysqld start
Starting mysqld: [ OK ]
[root@localhost mysql]# mysql -uroot
