来源整理于 https://www.cnblogs.com/wanghuaijun/p/6398240.html

虚拟机CentOS6.8下

先执行命令查看目录是否存在mysql 文件夹:  cd  /usr/local    再输入ll  

若存在

执行删除命令   rm -rf /usr/local/mysql

清空相关mysql的所有目录以及文件
rm -rf /usr/lib/mysql
rm -rf /usr/share/mysql

rm -rf /usr/my.cnf

删除mysql服务

[root@localhost local]# chkconfig --list | grep -i mysql
[root@localhost local]# chkconfig --del mysql

 

 

 

 

yum方式安装的mysql

 

1、yum remove mysql mysql-server mysql-libs compat-mysql51

2、rm -rf /var/lib/mysql

3、rm /etc/my.cnf

 

查看是否还有mysql软件:
rpm -qa|grep mysql

如果存在的话,继续删除即可。

 

rpm方式安装的mysql

 

 

a)查看系统中是否以rpm包安装的mysql:

 

[root@localhost opt]# rpm -qa | grep -i mysql
MySQL-server-5.6.17-1.el6.i686
MySQL-client-5.6.17-1.el6.i686

 

b)卸载mysql

[root@localhost local]# rpm -e MySQL-server-5.6.17-1.el6.i686
[root@localhost local]# rpm -e MySQL-client-5.6.17-1.el6.i686

c)删除mysql服务

[root@localhost local]# chkconfig --list | grep -i mysql
[root@localhost local]# chkconfig --del mysql

d)删除分散mysql文件夹

[root@localhost local]# whereis mysql 或者 find / -name mysql

 

mysql: /usr/lib/mysql /usr/share/mysql

清空相关mysql的所有目录以及文件
rm -rf /usr/lib/mysql
rm -rf /usr/share/mysql

rm -rf /usr/my.cnf

 

 

本文介绍了CentOS下MySQL的彻底卸载的几种方法,分享给大家,具体如下:

1:查看MySQL是否安装:

方式1:

[root@localhost usr] # yum list installed mysql*

  * updates: mirrors.yun-idc.com
Installed Packages
MySQL-client.x86_64  5.6.27-1.el6  installed
MySQL-devel.x86_64  5.6.27-1.el6  installed
MySQL-server.x86_64  5.6.27-1.el6  installed
[root@localhost usr] #

[root@localhost usr] # rpm -qa | grep -i mysql

MySQL-client-5.6.27-1.el6.x86_64
MySQL-devel-5.6.27-1.el6.x86_64

2:卸载MySQL:

卸载1:

3
[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

如果装了mysql-devel(其他一样add command),卸载为:

 

复制代码 代码如下:

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

 

 

注(例如):

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

[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/

注:删除MySQL数据库目录(关键) ,否则password不更新(默认安装,如果自定义安装路径和链接路径ln -s ……请删除。)
  rm -rf /var/lib/mysql

卸载3:

?
1

3
[root@localhost usr] # whereis mysql
mysql: /usr/lib64/mysql
[root@localhost usr] # rm -rf /usr/lib64/mysql

注:find / -name mysql

注:清空相关mysql的所有目录以及文件和其他配置和设置等。如果有,则删除。也必须考虑其他软件不去影响。

rm -rf /usr/lib/mysql

rm -rf /usr/share/mysql
