redhat7.3配置163 yum源

       redhat 的更新包只对注册的用户生效，因此咱们须要本身手动更改为CentOS 的更新包，CentOS几乎和redhat是同样的，因此无需担忧软件包是否可安装，安装以后是否有问题。

一、首先删除redhat原有的yum ，由于redhat 本来的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

二、下载163的yum 安装包

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

三、安装下载的rpm包

rpm -ivh *.rpm

四、建立文件/etc/yum.repos.d/rhel-debuginfo.repo并写入

[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/
gpgcheck=1
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

六、 yum clean all
七、 yum update 测试。

八、 安装 epel 源

yum install epel-release
