#查看当前安装mysql情况
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -qa|grep -i mysql

mysql-community-common-5.5.61-2.el6.x86\_64  
mysql-community-client-5.5.61-2.el6.x86\_64  
mysql-community-server-5.5.61-2.el6.x86\_64  
mysql-libs-5.1.73-8.el6\_8.x86\_64  
mysql-community-libs-5.5.61-2.el6.x86\_64

显示有如上几个,挨个卸载

[root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -ev mysql-community-common-5.5.61-2.el6.x86_64

报如下错误：  
error: Failed dependencies:  
mysql-community-common(x86-64) >= 5.5.8 is needed by (installed) mysql-community-libs-5.5.61-2.el6.x86\_64  
mysql-community-common(x86-64) = 5.5.61-2.el6 is needed by (installed) mysql-community-server-5.5.61-2.el6.x86\_64

重试如下命令：

[root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -ev mysql-community-common-5.5.61-2.el6.x86_64 --nodeps
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rmp -ev mysql-community-client-5.5.61-2.el6.x86_64 --nodeps
    bash: rmp: command not found
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -ev mysql-community-client-5.5.61-2.el6.x86_64 --nodeps
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -ev mysql-community-server-5.5.61-2.el6.x86_64 --nodeps
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -ev mysql-libs-5.1.73-8.el6_8.x86_64 --nodeps
    warning: /etc/my.cnf saved as /etc/my.cnf.rpmsave
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -ev mysql-community-libs-5.5.61-2.el6.x86_64 --nodeps

卸载完毕，再检查一下

[root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -qa|grep -i mysql
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]#

删除对应文件

[root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# find / -name mysql
    /var/lib/mysql
    /var/lib/mysql/mysql
    /usr/share/mysql
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rm -rf /var/lib/mysql/
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rm -rf /var/lib/mysql/mysql
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rm -rf /usr/share/mysql

配置文件也需要手动删除

[root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rm -rf /etc/my.cnf

再次确认

[root@iZwz97hxl5q1kwu1lhn5cwZ suntree]# rpm -qa|grep -i mysql
    [root@iZwz97hxl5q1kwu1lhn5cwZ suntree]#

搞定
