- # The mirror system uses the connecting IP address of the client and the
- # update status of each mirror to pick mirrors that are updated to and
- # geographically close to the client. You should use this for CentOS updates
- # unless you are manually picking other mirrors.

- # If the mirrorlist= does not work for you, as a fall back you can try the
- # remarked out baseurl= line instead.

附：增加RPMforge源
1，download the rpmforge package:
http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
2，Install DAG's GPG key
sudo rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
如果上面出現錯誤，確認下：
sudo rpm -K rpmforge-release-0.5.2-2.el6.rf.*.rpm
3，sudo rpm -i rpmforge-release-0.5.2-2.el6.rf.*.rpm
4，試試看：sudo yum install htop
開始更新系統：
yum update
