you’ll get a warning, but it will proceed based on the flags that you set. warning: rpmforge-release-0.5.2-1.el6.rf.x86_64.rpm : Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY

接下来最最重要的就是设置优先级了：
Now you need to edit /etc/yum.repos.d/CentOS-Base.repo and add these priorities to the bottoms of each of the following repo sections:
复制代码
[base]
priority=1
[updates]
priority=1
[extras]
priority=1
Save your changes on this file and edit the rpmforge.repo file. You’ll only need to edit the one repository section.
[rpmforge]
priority=5
Save your changes and you’re finished.
