redhat7.3配置163 yum源

       redhat 的更新包只對註冊的用戶生效，所以我們需要自己手動更改成CentOS 的更新包，CentOS幾乎和redhat是一樣的，所以無需擔心軟體包是否可安裝，安裝之後是否有問題。

1、首先刪除redhat原有的yum ，因為redhat 原本的yum 沒有註冊為redhat用戶是用不了的。

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

2、下載163的yum 安裝包

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

rpm -ivh *.rpm

6、 yum clean all
7、 yum update 測試。

8、 安裝 epel 源

yum install epel-release
