rhel 6.3 yum源更新为centos 6.4 的yum 源

beebe_3

　　由于rhel 6.3 的yum自己的源有诸多的限制，很多需要的软件是无法安装的，所以要更新为centos或freebsd的yum源，以便安装软件，不然各种软件之间的依赖关系搞死你！
　　本文参考：http://zhouxuguang.blog.运维网.com/1053090/896087
　　首先先卸载rhel 自带的yum
　　rpm -qa |grep yum|xarges rpm -e --nodeps
　　然后从网易的镜像站下载如下四个包，我把它放到了/home/yum目录下
　　wget http://mirrors.163.com/centos/6.4/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6.4/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6.4/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
wget http://mirrors.163.com/centos/6.4/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
wget http://mirrors.163.com/centos/6.4/os/i386/RPM-GPG-KEY-Centos-6
完了安装yum rpm 包
  rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm --nodeps
　　rpm  -ivh yum * --nodeps
　　然后把 mv /etc /yum .repos.d/rhel.repo  /etc /yum .repos.d/centos .repo
　　打开配置文件 vim/etc /yum .repos.d/centos .repo
　　以下是配置文件：
# 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.
#
