RedHat Enterprise Linux 6.X 使用Centos 6 的yum源

思路：卸载redhat自带yum，然后下载centos的yum，安装后修改配置文件1、首先到http://mirrors.163.com/centos下载软件包x86 地址：http://mirrors.163.com/centos/6/os/i386/Packages/x86_64 地址：http://mirrors.163.com/centos/6/os/x86_64/Packages/必要下载的软件包有（以64位系统为例）：a python-iniparse-0.3.1-2.1.el6.noarch.rpmb yum-3.2.29-40.el6.centos.noarch.rpmc yum-metadata-parser-1.1.2-16.el6.x86_64.rpmd yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm下载命令：

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpmwget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpmwget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpmwget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

[注] :版本不一定要最新的2、卸载RedHat自带的yum rpm -qa | grep yum | xargs rpm -e --nodeps注：a、xargs是一条Unix和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令，以避免参数列表过长的问题 b、--nodeps 强制卸载,不管依赖性3、安装下载的centos的yum包：rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpmrpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpmrpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm[注] :最后2个需要一起安装，否则会出现依赖性错误4、到http://mirrors.163.com的centos帮助文档中下载CentOS6-Base-163.repo文件，存放到/etc/yum.repo.d中wget http://mirrors.163.com/.help/CentOS6-Base-163.repo5、编辑CentOS6-Base-163.repo文件，将其中的$releasever更改为centos的版本号下面是修改好的：[align=center]

# 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.
