Mysql yi güncellediğimde şöyle bir hata verdi ve baslamıyor .

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!
Unable to reset root MySQL password. at /scripts/securemysql line 154.

MySQL manager or server PID file could not be found! [FAILED]

ne yapabiliriz ?
