附：增加RPMforge源

1，download the rpmforge package:

2，Install DAG's GPG key

sudo rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

如果上面出现错误，确认下：

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，试试看：sudo yum install htop

 

开始更新系统：

yum update
