\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#CentOS7下MySQL的卸载\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

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
