Rhel 5 升级为centos 5 并配置yum源
开发一台测试服务器原来用的是RHEL5,安装啊，更新包一点都不方便，整成CentOS 5吧，方便使用。
1.卸载掉原yum包
rpm -e yum-rhn-plugin-0.4.3-1.el5 yum-updatesd-3.0.1-5.el5
yum-3.0.1-5.el5 yum-metadata-parser-1.0-8.fc6 pirut-1.2.10-1.el5.noarch
rpm -e redhat-release-5Server-5.0.0.9 redhat-release-notes-5Server-5 –nodeps
2.下载安装CentOS中的yum包
mkdir yum
cd yum/
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-3.2.8-9.el5.centos.1.noarch.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-updatesd-0.9-2.el5.noarch.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-2.el5.x86_64.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/centos-release-5-2.el5.centos.x86_64.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/centos-release-notes-5.2-2.x86_64.rpm
rpm -Uvh *.rpm
3.导入RPM-GPG-KEY
rpm –import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
4.修改一下源，改成centos.ustc.edu.cn，我用着速度很爽。
yum update/install
搞定
