This article introduces several methods to completely uninstall MySQL under CentOS and shares them with you. The details are as follows:

1: check whether MySQL is installed:

Method 1:

[root@localhost usr] # yum list installed mysql*Loaded plugins: fastestmirrorLoading mirror speeds from cached hostfile * base: mirrors.yun-idc.com * extras: mirror.neu.edu.cn * updates: mirrors.yun-idc.comInstalled PackagesMySQL-client.x86_64 5.6.27-1.el6 installedMySQL-devel.x86_64 5.6.27-1.el6 installedMySQL-server.x86_64 5.6.27-1.el6 installed [root@localhost usr] #

Method 2 (- I: case-insensitive):

[root@localhost usr] # rpm-qa | grep-I mysqlMySQL-server-5.6.27-1.el6.x86_64MySQL-client-5.6.27-1.el6.x86_64MySQL-devel-5.6.27-1.el6.x86_64 [root@localhost usr] #

2: uninstall MySQL:

Uninstall 1:

[root@localhost usr] # yum remove mysql mysql-server mysql-libs compat-mysql51 [root@localhost usr] # rm-rf / var/lib/mysql [root@localhost usr] # rm / etc/my.cnf

If mysql-devel (other add command) is installed, uninstall it as follows:

The copy code is as follows:

[root@Tony_ts_tian init.d] # yum remove mysql mysql-devel mysql-server mysql-libs compat-mysql51

Note (for example):

Mysql-5.5.39-1.el6.remi.x86_64

Mysql-libs-5.5.39-1.el6.remi.x86_64

Compat-mysql51-5.1.54-1.el6.remi.x86_64

Mysql-server-5.5.39-1.el6.remi.x86_64

Uninstall 2 {continue, 1Pol 2 choose one (here for introduction):}:

[root@localhost mysql] # rpm-aq | grep-I mysqlMySQL-server-5.6.27-1.el6.x86_64MySQL-client-5.6.27-1.el6.x86_64MySQL-devel-5.6.27-1.el6.x86_64 [root@localhost mysql] # rpm-e MySQL-server-5.6.27-1.el6.x86_64 [root@localhost mysql] # rpm-e MySQL-client-5.6.27-1.el6.x86_64 [root@ Localhost mysql] # rpm-e MySQL-devel-5.6.27-1.el6.x86_64 [root@localhost rc.d] # cd / var/lib/ [root@localhost lib] # rm-rf mysql/

Note: delete the MySQL database directory (key), otherwise password will not update (default installation, if custom installation path and link path ln-s... Please delete it. )

Rm-rf / var/lib/mysql

[root@localhost usr] # whereis mysqlmysql: / usr/lib64/mysql [root@localhost usr] # rm-rf / usr/lib64/mysql

Note: find /-name mysql

Note: clear all directories, files and other configurations and settings related to mysql. If so, delete it. It must also be considered that other software will not affect it.

Rm-rf / usr/lib/mysql

Rm-rf / usr/share/mysql

Uninstall 4:

[root@localhost usr] # rm-rf / usr/my.cnf [root@localhost usr] # rm-rf / root/.mysql_sercret

Uninstall 5 (self-starting service):

[root@localhost usr] # chkconfig-- list | grep-I mysql [root@localhost usr] # chkconfig-- del mysqld

Delete here and see your own settings: mysql/mysqld
