rhel使用CentOS做为yum更新源
由于rhel没有注册码，之前一直用DVD做更新源，但是rhel又不能从官网上更新，怎么办呢，想想就使用CentOS的更新源吧：
首先把rhel自带的文件备份：
[root@test yum.repos.d]# cp rhel-debuginfo.repo rhel-debuginfo.repo.bak
[root@test yum.repos.d]# mv rhel-debuginfo.repo CentOS-Base.repo
[root@test yum.repos.d]# vi CentOS-Base.repo
[base]
name=CentOS-5-Base
repo=os
baseurl=http://centos.ustc.edu.cn/centos/5/os/$basearch/
gpgcheck=0
gpgkey=http://centos.ustuc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
[updates]
name=CentOS-5-Updates
baseurl=http://centos.ustc.edu.cn/centos/5/updates/$basearch/
gpgcheck=0
gpgkey=http://centos.ustuc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
[addons]
name=CentOS-5-Addons
baseurl=http://centos.ustc.edu.cn/centos/5/addons/$basearch/
gpgcheck=0
gpgkey=http://centos.ustuc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
[extras]
name=CentOS-5-Extras
baseurl=http://centos.ustc.edu.cn/centos/5/extras/$basearch/
gpgcheck=0
gpgkey=http://centos.ustuc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
[centosplus]
name=CentOS-5-Plus
baseurl=http://centos.ustc.edu.cn/centos/5/centosplus/$basearch/
gpgcheck=0
gpgkey=http://centos.ustuc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
[contrib]
name=CentOS-5-Contrib
baseurl=http://centos.ustc.edu.cn/centos/5/contrib/$basearch/
gpgcheck=0
gpgkey=http://centos.ustuc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
[root@test yum.repos.d]# rpm --import /etc/pki/rpm-gpg/RPM*
把虚拟机联网然后测试一下
[root@test yum.repos.d]# yum list
[root@test yum.repos.d]# yum install mysql

OK，成功了～～～～
如果要使用其他的更新源可以把配置文件中的baseurl中的更新网址换成其他的,比如
mirrors.163.com但是要注意路径和版本号～
国内比较好的CentOS更新源有163,sina，中科大等，如果有错误请自己看下错误日志，及把rhel自带的yum卸载安装CentOS的yum软件试试。
