引言：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

   wget 

         wget 

         wget 

         wget 

3、安装yum软件包

   rpm -ivh  python-iniparse-0.3.1-2.1.el6.noarch.rpm

         rpm -ivh  yum-metadata-parser-1.1.2-14.1.el6.i686.rpm

         rpm -ivh  yum-3.2.27-14.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm

  

   注意：最后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。

4、更改yum源  #我们使用网易的CentOS镜像源

   cd /etc/yum.repos.d/

   wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo

   vi CentOS6-Base-163.repo  #编辑文件

   把文件里面的$releasever全部替换为版本号，即6 最后保存！

或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可（已经修改好）

1 # CentOS-Base.repo

2 #

3 # The mirror system uses the connecting IP address of the client and the

4 # update status of each mirror to pick mirrors that are updated to and

5 # geographically close to the client. You should use this for CentOS updates

6 # unless you are manually picking other mirrors.

7 #

8 # If the mirrorlist= does not work for you, as a fall back you can try the

9 # remarked out baseurl= line instead.

10 #

5、yum clean all     #清理yum缓存

            yum makecache     #将服务器上的软件包信息缓存到本地,以提高搜索安装软件的速度

            yum install vim*  #测试yum是否可用

 

至此，Redhat6可以使用CentOS的yum源在线安装软件了！
