centos yum 源

# 備份

# mv /etc/yum.repos.d/CentOS-Base.repo{,.bak}

# 修改

# vi /etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo   

#   

# 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，确認下：

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
