RedHat Enterprise Linux 6.4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.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.## [base]name=CentOS-6 - Base - 163.combaseurl=http://mirrors.163.com/centos/6/os/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=osgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #released updates[updates]name=CentOS-6 - Updates - 163.combaseurl=http://mirrors.163.com/centos/6/updates/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updatesgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that may be useful[extras]name=CentOS-6 - Extras - 163.combaseurl=http://mirrors.163.com/centos/6/extras/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extrasgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that extend functionality of existing packages[centosplus]name=CentOS-6 - Plus - 163.combaseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplusgpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #contrib - packages by Centos Users[contrib]name=CentOS-6 - Contrib - 163.combaseurl=http://mirrors.163.com/centos/6/contrib/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contribgpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

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：Metadata Cache Created 欢迎转载，请注明出处，谢谢！
