redhat

错误原因

在使用未注册的 RedHat Linux 企业版时。使用yum命令会出现如下提示：

[root@localhost ~]# yum install httpd
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
Setting up Install Process
No package httpd available.
Nothing to do

解决方案

而这种情况可以使用CentOS的yum来代替掉系统本身的yum 脚本如下：

#!/bin/sh
rpm -qa | grep yum | xargs rpm -e --nodeps
wget  http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
wget  http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
wget  http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
rpm -ivh yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
rpm -ivh yum-3.2.22-39.el5.centos.noarch.rpm
wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo
mv CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo
rm -f yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
rm -f yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
rm -f yum-3.2.22-39.el5.centos.noarch.rpm
rm -f CentOS-Base.repo

将上面的脚本保存为：redhat_use_centos_yum.sh

点击这里直接下载 redhat_use_centos_yum.sh 然后直接运行这个脚本即可。

一键脚本

如果闲麻烦也可以依次输入下面几条指令来下载并执行我已经写好的脚本，同样可以达到目的：

wget http://www.leelib.com/wp-content/uploads/2012/04/redhat_use_centos_yum.sh
chmod 777 redhat_use_centos_yum.sh
sudo ./redhat_use_centos_yum.sh

现在再试试yum命令是否已经没有了 This system is not registered with RHN. 提示，并且可以正常使用了呢！ :)
