1、查看MySQL是否安装

 方式1:

[root@localhost usr]# yum list installed mysql*  
Loaded plugins: fastestmirror  
Loading mirror speeds from cached hostfile  
 * base: mirrors.yun-idc.com  
 * extras: mirror.neu.edu.cn  
 * 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]#  

  方式2( -i  :不区分大小写):

[root@localhost usr]# rpm -qa | grep -i mysql  
MySQL-server-5.6.27-1.el6.x86_64  
MySQL-client-5.6.27-1.el6.x86_64  
MySQL-devel-5.6.27-1.el6.x86_64  
[root@localhost usr]#   

  2、卸载MySQL

 

卸载1:

[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:

[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
卸载2{继续,1,2选择一种(此处为介绍):}:

[root@localhost mysql]# rpm -aq | grep -i mysql  
MySQL-server-5.6.27-1.el6.x86_64  
MySQL-client-5.6.27-1.el6.x86_64  
MySQL-devel-5.6.27-1.el6.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:

[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
卸载4:

[root@localhost usr]# rm –rf /usr/my.cnf  
[root@localhost usr]# rm -rf /root/.mysql_sercret   

  卸载5(自启服务):

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

  

此处删除看自己设置:mysql/mysqld
