RPM-style installation of MySQL

A) Check to see if MySQL is installed in the RPM package on 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 MySQL service

[root@localhost local]# chkconfig--list | Grep-i MySQL
[Root@localhost local]# chkconfig--del MySQL

d) Delete the distributed MySQL folder

[[email protected] local]# Whereis MySQL or find/-name mysql

MySQL:/usr/lib/mysql/usr/share/mysql

Empty all directories and files related to MySQL
Rm-rf/usr/lib/mysql
Rm-rf/usr/share/mysql

Rm-rf/usr/my.cnf

With these steps, MySQL should have been completely uninstalled.
