RedHat 6.0使用CentOS YUM源更新的方法

黑夜

　由于Redhat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Redhat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redhat原有的yum源

1. # rpm -aq | grep yum|xargs rpm -e --nodeps
   
2. 
   

复制代码

2、下载新的yum安装包 　　这里我们使用CentOS的yum源

1. # wget http://mirror.centos.org/centos/6.0/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
   
2. # wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-metadata-parser-1.1.2-14.1.el6.i686.rpm
   
3. # wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-3.2.27-14.el6.centos.noarch.rpm
   
4. # wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-plugin-fastestmirror-1.1.26-1.el6.noarch.rpm

复制代码

[b]3、安装yum软件包

1. # rpm -ivh  python-iniparse-0.3.1-2.1.el6.noarch.rpm
   
2. # rpm -ivh  yum-metadata-parser-1.1.2-14.1.el6.i686.rpm
   
3. # rpm -ivh  yum-3.2.27-14.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm
   

复制代码

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

1. 
   
2. # cd /etc/yum.repos.d/
   
3. # wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo
   
4. # vi CentOS6-Base-163.rep.noarch.rpm

复制代码

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）

3. #
   
4. # The mirror system uses the connecting IP address of the client and the
   
5. # update status of each mirror to pick mirrors that are updated to and
   
6. # geographically close to the client. You should use this for CentOS updates
   
7. # unless you are manually picking other mirrors.
   
8. #
   
9. # If the mirrorlist= does not work for you, as a fall back you can try the
   
10. # remarked out baseurl= line instead.

5、清理yum缓存

1. # yum clean all
   
2. # 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
   
3. # yum install vim* #测试域名是否可用

复制代码

温馨提示：163的版本不可以低于机器版本，要不是会出现问题的，最好可以用 Fedora的版本
