5.安装 DAG 的 GPG key
rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
6.编辑 /etc/yum.repos.d/ 路径下的 .repo 文件，通过添加以下文本行来创建 priorities：
priority=N
对应于每个安装源入口，N 是一个从 1 到 99 的整数。
建议的配置是(CentOS-Base.repo文件)：
[base], [addons], [updates], [extras] ... priority=1
[centosplus], [contrib] ... priority=2
7.yum install nload 安装成功，说明安装好RPMForge 了
其他没有安装RPMforge的服务器安装nload提示
