首先檢視mysql服務狀態

[[email protected] data]# service mysql status
MySQL is running                                       [SUCCESS]

如果mysql正在執行中停止mysql服務，否則不用停止

[[email protected] data]# service mysql stop

檢視有哪些mysql的rpm包

[[email protected] ~]# rpm -qa | grep -i mysql
MySQL-devel-5.5.62-1.el6.x86_64
mysql-libs-5.1.71-1.el6.x86_64
MySQL-server-5.5.62-1.el6.x86_64
MySQL-client-5.5.62-1.el6.x86_64
MySQL-shared-compat-5.5.62-1.el6.x86_64
MySQL-shared-5.5.62-1.el6.x86_64
 

分別執行解除安裝各個rpm包命令

[[email protected] ~]# rpm -e MySQL-server-5.5.62-1.el6.x86_64
[[email protected] ~]# rpm -e MySQL-devel-5.5.62-1.el6.x86_64
[[email protected] ~]# rpm -e MySQL-client-5.5.62-1.el6.x86_64
[[email protected] ~]# rpm -e mysql-libs-5.1.71-1.el6.x86_64
[[email protected]
 
 ~]# rpm -e MySQL-shared-5.5.62-1.el6.x86_64
[[email protected] ~]# rpm -e MySQL-shared-compat-5.5.62-1.el6.x86_64

檢視mysql相關資料夾

[[email protected] ~]# find / -name mysql
/var/lib/mysql
/var/lib/mysql/mysql
/usr/lib64/mysql

刪除相關資料夾

[[email protected] ~]# rm -rf /var/lib/mysql
[[email protected]
 
 ~]# rm -rf /usr/lib64/mysql

到此解除安裝完成
