redhat6.4配置centos6 yum替换

1、卸载掉系统redhat自带的yum

rpm -qa |grep yum |xargs rpm -e --nodeps

2 下载相关的centos yum插件

主要有python-iniparse-0.3.1-2.1.el6.noarch.rpm

yum-3.2.29-40.el6.centos.noarch.rpm

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

yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

其中版本号和安装的系统版本，以及时32位系统和64位系统有关系

下载地址：http://mirrors.163.com/centos/

在linux可以使用命令直接下载到本地也可以

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
注意：如果下载不了可能是小版本号有变化，可以直接下载后在上传到linux服务器

3 安装下载的yum包（如果没权限可以先修改权限 chmod 777 *）

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

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

rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

最后两个需要一起安装，有相互依赖关系

4 下载配置文件CentOS6-Base-163.repo

# cd /etc/yum.repos.d/

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

5 修改CentOS6-Base-163.repo ，将其中的$releasever 更改为centos的版本

vi CentOS6-Base-163.repo

：%s/$releasever/6

# 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.

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

至此，Redhat6可以使用CentOS的yum源在线安装软件了。
