RHEL7.3-yum源配置

1.首先刪除redhat原有的yum ，因爲redhat 原本的yum 沒有註冊爲redhat用戶是用不了的，輸入如下命令行：

rpm -e yum --nodeps

2.下載163的yum 安裝

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/yum-plugin-fastestmirror-1.1.31-40.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

3.安裝下載的rpm包

rpm -ivh *.rpm

4.編輯文件/etc/yum.repos.d/rhel-debuginfo.repo並寫入，刪除自帶的.repo文件
