本文详细介绍了一种彻底卸载MySQL的方法，包括停止服务、删除安装目录、清除配置文件及用户组等步骤。

1、检查mysql服务
[root@jdap01 ~]# ps -ef |grep mysql

root 11357 15693 0 09:25 pts/1 00:00:00 grep mysql
root 16356 1 0 Apr21 pts/1 00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe –datadir=/usr/local/mysql/data –pid-file=/usr/local/mysql/data/jdap01.pid
mysql 16478 16356 0 Apr21 pts/1 00:08:03 /usr/local/mysql/bin/mysqld –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data –plugin-dir=/usr/local/mysql/lib/plugin –user=mysql –log-error=/usr/local/mysql/data/jdap01.err –pid-file=/usr/local/mysql/data/jdap01.pid

2、查看进程
[root@jdap01 ~]# /usr/local/mysql/support-files/mysql.server status

MySQL running (16478) [ OK ]

3、关闭mysql进程

[root@jdap01 ~]# /usr/local/mysql/support-files/mysql.server stop

Shutting down MySQL.. [ OK ]

4、关闭之后再查看进程

[root@jdap01 ~]# /usr/local/mysql/support-files/mysql.server status

MySQL is not running [FAILED]

5、查找mysql的安装目录

[root@jdap01 ~]#

whereis mysql
mysql: /etc/mysql /usr/local/mysql

或者
[root@jdap01 ~]# find / -name mysql

/var/lock/subsys/mysql
/home/mw/weblogic/wlserver_10.3/server/db/mysql
/home/mw/weblogic/wlserver_10.3/server/ext/jdbc/mysql
/etc/mysql
/etc/rc.d/init.d/mysql
/usr/local/mysql
/usr/local/mysql/data/mysql
/usr/local/mysql/include/mysql
/usr/local/mysql/bin/mysql

6、删除当时安装的mysql目录

[root@jdap01 ~]# rm -rf /usr/local/mysql

7、删除一些配置文件

[root@jdap01 ~]# rm -rf /etc/my.cnf

8、删除mysql用户以及用户组

[root@jdap01 ~]# id mysql

uid=501(mysql) gid=501(mysql) groups=501(mysql)

[root@jdap01 ~]# userdel mysql
[root@jdap01 ~]# id mysql

Id: mysql: No such user 到此，删除mysql成功！！！
