1、查看当前系统版本和内核版本

[root@mdadm ~]# uname -a

Linux mdadm.lvmadm 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

[root@mdadm ~]# cat /etc/redhat-release 

Red Hat Enterprise Linux Server release 6.4 (Santiago)

2、测试网络的联通性

[root@mdadm ~]# ping www.baidu.com

PING www.a.shifen.com (115.239.211.112) 56(84) bytes of data.

64 bytes from 115.239.211.112: icmp_seq=1 ttl=54 time=43.5 ms

64 bytes from 115.239.211.112: icmp_seq=2 ttl=54 time=43.3 ms

3、正式开始

    总共需要安装3个包包，可以从163的mirror服务器下载

1. yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm 

2. yum-metadata-parser-1.1.2-16.el6.x86_64.rpm 

3. yum-3.2.29-60.el6.centos.noarch.rpm

[root@mdadm ~]#cd /etc/yum.repos.d/

[root@mdadm yum.repos.d]# vim CentOS6-Base-163.repo

用命令g/$releasever/s//6/把文件里面的$releasever全部替换为版本号，即6最后保存。

4、测试yum

[root@mdadm yum.repos.d]#yum clean all

[root@mdadm yum.repos.d]#yum makecache

[root@mdadm yum.repos.d]#yum install vim*

# yum install vim*    #测试域名是否可用

至此，Redhat6可以使用CentOS的yum源在线安装软件了。
