RedHat Enterprise Linux 6.4使用Centos 6的yum源

搜鞥都哦

　　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.rpm
　　b  yum-3.2.29-40.el6.centos.noarch.rpm
　　c  yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
　　d  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.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] :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.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

[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.repo
　　5、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：
　　# 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.
　　#
　　#

　　6、yum clean all 清除原有缓存
　　7、yum makecache  获取yum列表
　　出现下面提示，表示yum更改完成：
