rhel6.3使用centos的Yum源

由于RHEL的yum在线更新是收费的，如果没有注册的话是不能使用的，即不能在线安装软件。在这种情况下，想使用RHEL系统，还想用yum源来在线安装软件，有没有办法？答案是有办法，请往下看！
1、删除RHEL原有的yum
rpm -aq|grep yum|xargs rpm -e --nodeps #删除
2、下载新的yum安装包 #这里我们使用CentOS的yum源
下载地址;http://mirror.centos.org/centos-6/6/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
http://mirror.centos.org/centos-6/6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
http://mirror.centos.org/centos-6/6/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm
http://mirror.centos.org/centos-6/6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
3、安装yum软件包

[root@localhost src]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
warning: python-iniparse-0.3.1-2.1.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY

#注意：以下两个安装包要放在一起同时安装，否则会提示相互依赖，安装失败。
[root@localhost src]# rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

4、更改yum源 #我们使用网易的CentOS镜像源
