1、删除Centos 或者redhat原有的yum源

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

2、重新从网上获取yum的安装包

以root登陆到Centos6 系统,默认目录已经切换到 /root

分别执行以下四条命令：

# wget http://mirror.centos.org/centos/6.0/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

# wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-metadata-parser-1.1.2-14.1.el6.i686.rpm

# wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-3.2.27-14.el6.centos.noarch.rpm

# wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm

即可把需要的软件全部下载本地 /root目录下

 

3.安装软件包

# 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

*****后面两个软件包要一起执行，否则会出现依赖关系找不到的情况。*****

4、更改yum源，使用网易的镜像站。

切换目录到 /etc/yum.repos.d/目录下

# 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）。 

 

# CentOS-Base.repo

#

# 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.

#
