rhel源更换为centos源

0x00.

YUM是RedHat Linux在线安装更新及软件的工具，但是这是RHEL5的收费功能，如果没有购买Redhat的服务时不能使用RHEL的更新源的，会提示注册。

由于CentOS是从RedHat演化而来的免费Linux版本，因此可以利用CentOS的yum更新源来实现RHEL5的YUM功能。配置方法如下：

0x01.删除rhel自带的yum包：

rpm -aq | grep yum |xargs rpm -e --nodeps

0x02.安装yum：

wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-3.2.29-69.el6.centos.noarch.rpm wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm wget http://mirrors.163.com/centos/6/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
