How to completely delete mysql from Centos

1. MySQL installed in yum Mode

$ Yum remove mysql-server mysql-libs compat-mysql51

$ Rm-rf/var/lib/mysq

$ Rm/etc/my. cnf

Check whether there is any mysql software:

$ Rpm-qa | grep mysql

If yes, continue to delete it. The deletion method is yum remove + [name ].

2. mysql installed in rpm Mode

A) Check whether mysql is installed with an rpm package in the system:

[Root @ localhost opt] # rpm-qa | grep-I mysql
MySQL-server-5.6.17-1.el6.i686
MySQL-client-5.6.17-1.el6.i686

B) uninstall mysql

[Root @ localhost local] # rpm-e MySQL-server-5.6.17-1.el6.i686
[Root @ localhost local] # rpm-e MySQL-client-5.6.17-1.el6.i686

C) delete the mysql Service

[Root @ localhost local] # chkconfig -- list | grep-I mysql
[Root @ localhost local] # chkconfig -- del mysql

D) Delete the scattered mysql folder.

[Root @ localhost local] # whereis mysql or find/-name mysql

Mysql:/usr/lib/mysql/usr/share/mysql

Clear all related mysql directories and files
Rm-rf/usr/lib/mysql
Rm-rf/usr/share/mysql

Rm-rf/usr/my. cnf

After completing the steps above, mysql should have been completely uninstalled.
