【LINUX日记】RedHat7 配置国内yum源

1.卸载之前的yum，移除与原yum的依赖

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

2.下载yum包

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/rpm-4.11.3-43.el7.x86_64.rpm  
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm  
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-10.el7.noarch.rpm   
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-167.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-53.el7.noarch.rpm 

备注：最新的安装包名字有可能不同，需要登到 http://mirrors.163.com/centos/7/os/x86_64/Packages/去寻找最新的安装包名字，再进行下载

3.强制替换安装

rpm -ivh yum-3.4.3-167.el7.centos.noarch.rpm yum-metadata-parser-1.1.4-10.el7.x86_64.rpm python-urlgrabber-3.10-10.el7.noarch.rpm yum-plugin-fastestmirror-1.1.31-53.el7.noarch.rpm --nodeps --force

4.下载CentOS 7的repo文件

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

下载后需要全文替换$releasever为7

5.显示已配置的源
yum repolist
