安装了virtualmin/webmin后，使用 yum 安装 mysql 报错

原因：是安装virtualmin/webmin，自动安装了i386,x86_64版本的mysql，导致无法更新。

[root@webhosting999 ~]# rpm -qa|grep mysql --查看已安装的Mysql
mysql-5.0.77-4.el5_5.3
mysql-server-5.0.77-4.el5_5.3
mysql-devel-5.0.77-4.el5_5.3
mysql-5.0.77-4.el5_5.3
php-mysql-5.1.6-27.el5
mysql-devel-5.0.77-4.el5_5.3

使用 update php 5.2.14-jason 更新：

Error Summary

卸载mysql-5.0.77-4.el5_5.3.i386 --请先备份好数据库，以免操作失误，导致数据丢失。

[root@webhosting138 ~]# rpm -e --nodeps mysql-5.0.77-4.el5_5.3.i386

[root@webhosting138 ~]# rpm -e --nodeps mysql-server-5.0.77-4.el5_5.3.i386

再次运行#yum update -y php --按照update php 5.2.14-jason下部分操作。

如果不行（phpMyAdmin无法检查到php-mysql扩展），就先卸载全部的mysql，先安装mysql，在执行更新php。

#rpm -e 卸载mysql，具体先查询安装的mysql版本

#yum install -y mysql*5.1.50

注意：升级完成后要记得'mysql_upgrade'，否则无法webmin正常使用mysql
