How to uninstall mysql completely in CentOS, I believe many inexperienced people are helpless about this, for this reason this article summarizes the causes and solutions of the problem, through this article I hope you can solve this problem.

Check if MySQL is installed.

Mode 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

Unloading 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 is installed (the same as add command), uninstall is:

[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

Unload2 {Continue, 1, 2 Select one (here is an 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 MySQL database directory (key), otherwise password will not be updated (default installation, if custom installation path and link path ln -s …please delete.)
