Solution for mysql. sock not found in Linux

The following information is displayed:

Got an error: Connection error: Can't connect to local MySQL server through socket '/var/lib/mysql. sock'

The sudden disappearance of mysql. sock is a common problem. If MySQL is installed for the first time, you only need to find out where mysql. sock is.

The preceding error message, mysql. sock, should be in/var/lib/mysql/. If not, click:

# Find/-name mysql. sock

Find out where to put it, and then try again:

# Mysqladmin-S/find the path/mysql. sock-u root {parameter}

That... What should I do if I suddenly disappear or cannot be found?

You have to restart mysql. the tarball installation can be restarted through mysqld or mysqladmin, And the rpm installation can be performed through service mysql restart. However, when mysql. sock does not exist, it may be impossible to restart mysql. If it does not work, you have to first:

# Ps-aux | grep mysql

Then we cut down the pid.

# Kill the pid

Are you sure you have killed all of them?

# Ps-aux | grep mysql

Make sure that none of mysql is in it, and then execute mysqld or service mysql start.
