linux卸载MySQL

Linux卸载MySQL 找出以前是否装有mysqlrpmm -qa|grep -i mysql显示器安装前：MySQL-server-5.6.22-1.el6.i686MySQL-client-5.6.22-1.el6.i686

二 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-5.6.22-1.el6.i686rpm -ev MySQL-client-5.6.22-1.el6.i686

如果提示依赖包错误，请使用以下命令尝试rpm -ev MySQL-client-5.6.22-1.el6.i686 --nodeps

若提示错误：error: %preun(xxxxxx) scriptlet failed, exit status 一是用以下命令尝试：rpm -e --noscripts MySQL-client-5.6.22-1.el6.i686

三 查找旧版本的mysql目录，删除旧版本的mysql文件和库find / -name mysql

搜索结果如下：find / -name mysql

/var/lib/mysql/var/lib/mysql/mysql/run/lock/subsys/mysql/etc/selinux/targeted/active/modules/100/mysql/usr/lib64/mysql/usr/share/mysql/usr/lib/mysql/usr/local/mysql

删除相应的mysql目录rm -rf /usr/lib/mysqlrm -rf /usr/local/mysqlrm -rf /usr/lib64/mysqlrm -rf /run/lock/subsys/mysqlrm -rf /etc/selinux/targeted/active/modules/100/mysql…

四 卸载后/etc/my.cnf不会被删除，rm需要手动删除 -rf /etc/my.cnf

五 再次检查机器是否安装mysqlrpmm -qa|grep -i mysql
