前言

在redhat系统中，使用yum命令下载安装包的时候报错：This system is not registered to Red Hat Subscription Management.You can use subscription-manager to register

提示需要注册付费

更换yum源

1、卸载系统自带的yum源

rpm -qa|grep yum|xargs rpm -e --nodeps 卸载
rpm -qa|grep yum 查看

2、下载安装国内的yum源

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

安装yum源

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh --force python-urlgrabber-3.9.1-11.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm 
rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

3、更改repo文件

备份自带repo文件

cd /etc/yum.repos.d  切换到文件路径
mv rhel-source.repo rhel-source.repo.bak 备份

下载配置repo文件

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo    需在/etc/yum.repos.d路径下操作
vim CentOS6-Base-163.repo 修改配置
:1,$s/$releasever/6    全文替换releasever为6

4、生成缓存

执行命令需保证服务器可以联网，不然会报错，提示无法访问镜像源

yum clean all
yum makecache
