redhat6.3下配置使用cenos yum源

8700

1、删除redhat原有的yum源

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

2、下载新的yum安装包（CentOS的yum源）

注：rmp包版本可能有更新，如出现无法下载的情况，请自行网上找到相对应的高级版本下载使用

# wget http://mirror.centos.org/centos/ ... -2.1.el6.noarch.rpm

# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm

# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm

# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

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  此处使用网易的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）

:%s/$releasever/6/g

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

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

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

# unless you are manually picking other mirrors.

#

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

# remarked out baseurl= line instead.

5、清理yum缓存

# yum clean all

# 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*    #测试域名是否可用

　　到此，Redhat6.3就可以使用CentOS的yum源在线安装软件了！
