Redhat7.2配置免費yum源（簡單五步輕松搞定）

步驟一：清除redhat原有的yum源

步驟二：下載下傳163的yum包

wget http://mirrors.163.com/centos/7.2.1511/os/x86_64/Packages/yum-3.4.3-132.el7.centos.0.1.noarch.rpm

wget http://mirrors.163.com/centos/7.2.1511/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm   wget http://mirrors.163.com/centos/7.2.1511/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

wget http://mirrors.163.com/centos/7.2.1511/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm

步驟三：安裝下載下傳的yum包

步驟四：建立檔案/etc/yum.repos.d/rhel-Base.repo并寫入（複制我的即可）
