使用CentOS配置Redhat server7.0的yum源

首先删除原来的yum

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

rpm -aq|grep
python-iniparse|xargs rpm -e --nodeps

第二步：下载centos的rpm安装包

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-154.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.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/yum-plugin-fastestmirror-1.1.31-42.el7.noarch.rpm
第三步：安装rpm包

rpm -ivh *.rpm --nodeps

第五步：新建repo文件，这里命名为rhel.repo,编辑文件，写入下面内容

[base]

name=CentOS-$releasever - Base

baseurl=http://mirrors.163.com/centos/7/os/$basearch/

gpgcheck=1
http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7
#released updates

[updates]

name=CentOS-$releasever - Updates

baseurl=http://mirrors.163.com/centos/7/updates/$basearch/

gpgcheck=1
http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7
[extras]

name=CentOS-$releasever - Extras

baseurl=http://mirrors.163.com/centos/7/extras/$basearch/

gpgcheck=1

gpgkey=http://mirrors.163.com/centos/7.2.1511/os/x86_64/RPM-GPG-KEY-CentOS-7

[centosplus]

name=CentOS-$releasever - Plus

baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/

gpgcheck=1

enabled=0

然后执行 yum clear all

yum update 测试
