Centos7 配置163yum源

1、首先删除redhat原有的yum ，因为redhat 原本的yum 没有注册为redhat用户是用不了的。

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

2、下载163yum源包

这里需要查看版本号和系统类别：(参考 Linux下 RabbitMQ的安装与配置-3）
       

 cat /etc/redhat-release
 arch

然后找到对应的yum源（本人这里是百度的，实在不知道怎么查，有知道求分享）

wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-3.4.3-150.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm

3、安装下载的rpm包(也可以逐条安装）

rpm -ivh *.rpm

4、创建文件vim /etc/yum.repos.d/rhel-debuginfo.repo并写入（参考redhat7.3配置163 yum源）

[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/7.3.1611/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7
 
 
#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/7.3.1611/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7
 
 
[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.163.com/centos/7.3.1611/extras//$basearch/

gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7
 
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.163.com/centos/7.3.1611/centosplus//$basearch/
gpgcheck=1
enabled=0

6、 yum clean all
7、 yum update 测试。(时间稍长，需要确认)

8、 安装 epel 源

yum install epel-release
