rhel使用yum时出现：This system is not registered with RHN
解决方法：换成centos的yum
1.卸载rhel的默认安装的yum包
查看yum包
rpm -qa|grep yum卸载
rpm -qa|grep yum|xargs rpm -e --nodeps2.下载新的yum包
wget http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-3.2.22-37.el5.centos.noarch.rpm
wget http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-16.el5.centos.noarch.rpm
wget http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm并且安装
rpm -ivh yum-*注意：yum和yum-fastestmirror相互依赖，所以同时安装即可。
3.下载yum的配置源
wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo4.修改配置源
把CentOS-Base.repo里面的url改成网易的yum源 http://mirrors.163.com/centos/5/os/i386/（有什么软件包，可以很清楚的看见）5.全部更新
把修改后的CentOS-Base.repo复制到/etc/yum.repos.d/目录下
