rhel5 没有注册不能使用yum？

linux rhel5版本由于没有注册，导致yum无法使用，可以使用centos的yum来解决这个问题
首先卸载系统的yum

一、删除redhat5自带的yum

rpm -qa|grep yum|xargs rpm -e –nodeps

二、安装centos5.4光盘中的或从官方下载

wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/yum-3.2.22-20.el5.centos.noarch.rpm
wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm
wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm

wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/python-elementtree-1.2.6-5.x86_64.rpm
wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/python-sqlite-1.1.7-1.2.1.x86_64.rpm
wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/rpm-python-4.4.2.3-18.el5.x86_64.rpm
wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/python-urlgrabber-3.1.0-5.el5.noarch.rpm

wget http://mirrors.163.com/centos/5.4/os/x86_64/CentOS/m2crypto-0.16-6.el5.6.x86_64.rpm

rpm -ivh m2crypto-0.16-6.el5.6.x86_64.rpm
rpm -ivh python-*
rpm -ivh rpm-python
rpm -ivh yum-*

注意同时安装

三、下载配置

cd /etc/yum.repos.d/

wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo
