卸载linux系统自带的mysql

【注：绿色为屏幕打印内容】

【注：红色为前台输入内容】

由于redhat Enterprise 5中自带一个mysql的版本，如果在安装linux前未选择mysql的安装此步就可跳过，因为我当时安装了现在将其卸载，步骤如下：

       a.查找已安装的myslq版本：
        #rpm  -qa | grep  mysql（注意大小写，如果mysql不行就换MySQL）
出现：

        [root@oracle2 ~]# rpm  -qa | grep  mysql

         mod_auth_mysql-3.0.0-3.1

         mysql-connector-odbc-3.51.12-2.2

         mysql-5.0.45-7.el5

         php-mysql-5.1.6-23.el5

         mysql-server-5.0.45-7.el5

         mysql-devel-5.0.45-7.el5

         libdbi-dbd-mysql-0.8.1a-1.2.2

         mysql-bench-5.0.45-7.el5

 

卸载后/var/lib/mysql中的数据及/etc/my.cnf不会删除，如果确定没用后就手工删除
　　rm -f /etc/my.cnf
　　rm -rf /var/lib/mysql

 

然后输入卸载命令（yum -y remove m...）：

[root@oracle2 ~]# sudo yum -y remove mysql-5.0.45-7.el5

 

出现如下提示：

 

[root@oracle2 ~]# sudo yum -y remove mysql-5.0.45-7.e15

到此，Linux下自带的mysql已经完全卸载，此时，再输入：
[ysong@sva_rec mysql]$ rpm  -qa | grep  mysql
[ysong@sva_rec mysql]$
 
显示系统已经没有mysql服务。
