**1： 检查是否安装了MySQL组件。**

[root@DB-Server init.d]# rpm -qa | grep -i mysql
    MySQL-devel-5.6.23-1.linux_glibc2.5
    MySQL-client-5.6.23-1.linux_glibc2.5
    MySQL-server-5.6.23-1.linux_glibc2.5

如上所示，说明安装了MySQL 5.6.23这个版本的client、server、devel三个组件。

**2： 卸载前关闭MySQL服务**

[root@DB-Server init.d]# service mysql status
     MySQL running (25673)[  OK  ]
    [root@DB-Server init.d]# service mysql stop
     Shutting down MySQL..[  OK  ]
    [root@DB-Server init.d]# service mysql status
     MySQL is not running[FAILED]

**3. 收集MySQL对应的文件夹信息**

[root@DB-Server init.d]# find / -name mysql
    /etc/rc.d/init.d/mysql
    /etc/logrotate.d/mysql
    /var/lock/subsys/mysql
    /var/lib/mysql
    /var/lib/mysql/mysql
    /usr/include/mysql
    /usr/include/mysql/mysql
    /usr/bin/mysql
    /usr/share/mysql
    /usr/lib64/mysql

**4： 卸载删除MySQL各类组件**

[root@DB-Server init.d]# 
    [root@DB-Server init.d]# rpm -ev MySQL-devel-5.6.23-1.linux_glibc2.5
    [root@DB-Server init.d]# rpm -ev MySQL-server-5.6.23-1.linux_glibc2.5
    You have new mail in /var/spool/mail/root
    [root@DB-Server init.d]# rpm -ev MySQL-client-5.6.23-1.linux_glibc2.5
    [root@DB-Server init.d]#

**5：删除MySQL对应的文件夹**

[root@DB-Server init.d]# whereis mysql
    mysql:
    [root@DB-Server init.d]# find / -name mysql
    /var/lib/mysql
    /var/lib/mysql/mysql
    /usr/lib64/mysql
    [root@DB-Server init.d]# rm -rf /var/lib/mysql
    [root@DB-Server init.d]# rm -rf /var/lib/mysql/mysql
    [root@DB-Server init.d]# rm -rf /usr/lib64/mysql
    [root@DB-Server init.d]#

**6：删除mysql用户及用户组**

[root@DB-Server ~]# more /etc/passwd | grep mysql
    mysql:x:101:501::/home/mysql:/bin/bash
    [root@DB-Server ~]# more /etc/shadow | grep mysql
    mysql:!!:16496::::::
    [root@DB-Server ~]# more /etc/group | grep mysql
    mysql:x:501:
    [root@DB-Server ~]# userdel mysql
    [root@DB-Server ~]# groupdel mysql
    groupdel: group mysql does not exist
    [root@DB-Server ~]#

**7：确认MySQL是否卸载删除**

**　　**

[root@DB-Server init.d]# rpm -qa | grep -i mysql
