linux下卸载通过rpm安装的mysql

郑全

1、查找以前是否装有mysql

命令：rpm -qa|grep -i mysql
可以看到如下图的所示：

 

rpm -qa|grep -i mysql

MySQL-client-advanced-5.6.21-1.el6.x86_64
MySQL-server-advanced-5.6.21-1.el6.x86_64
mysql-connector-python-2.0.2-1.el6.noarch
mysql-workbench-commercial-6.2.3-1.el6.x86_64
MySQL-test-advanced-5.6.21-1.el6.x86_64

 

 

 

说明之前安装了：
MySQL-client-advanced-5.6.21-1.el6.x86_64
MySQL-server-advanced-5.6.21-1.el6.x86_64
mysql-connector-python-2.0.2-1.el6.noarch
mysql-workbench-commercial-6.2.3-1.el6.x86_64
MySQL-test-advanced-5.6.21-1.el6.x86_64

 

2、停止mysql服务、删除之前安装的mysql

删除命令：rpm -e –nodeps 包名
# rpm -ev MySQL-server-advanced-5.6.21-1.el6.x86_64 MySQL-client-advanced-5.6.21-1.el6.x86_64
   mysql-connector-python-2.0.2-1.el6.noarch mysql-workbench-commercial-6.2.3-1.el6.x86_64
   MySQL-test-advanced-5.6.21-1.el6.x86_64

3、查找之前老版本mysql的目录、并且删除老版本mysql的文件和库

find / -name mysql
查找结果如下：
[root@localhost ~]# find / -name mysql
/var/lib/mysql
/var/lib/mysql/mysql
/usr/lib64/mysql

删除对应的mysql目录
rm -rf /var/lib/mysql
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
具体的步骤如图：查找目录并删除

rm -fr /opt/mysql
rm -fr /apps/mysql-utilities-commercial-1.5.2-py2.7/
rm -fr /var/lib/mysql3309
rm -fr /var/lib/mysql3308
rm -fr /var/lib/mysql3307
rm -fr /usr/lib64/mysql
rm -fr /usr/etc/mysql
rm -fr /usr/share/mysql
rm -fr /usr/lib/python2.6/site-packages/mysql

rm -fr /var/lib/mysql

 

注意：卸载后/etc/my.cnf不会删除，需要进行手工删除
 rm -rf /etc/my.cnf

4、再次查找机器是否安装mysql

rpm -qa|grep -i mysql
无结果，说明已经卸载彻底、接下来直接安装mysql即可
