CentOS 5.5 yum 更新国内镜像,centosyum

搜狐的开源镜像http://mirrors.sohu.com/ 感觉蛮快的 不错！！

按以下步骤进行：

1、备份并清空 /etc/yum.repos.d/CentOS-Base.repo

echo "" > /etc/yum.repos.d/CentOS-Base.repo

或者(如果第一次使用的话)

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.DEFAULT

2、下载CentOS中文更新镜像配置文件，按照需要修改一下，如你的发行版为4那就把centos5改成centos4即可。然后：

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

a

粘贴配置文件的内容

以下为本人修改并校验的更新：

# CentOS-Base.repo

#

# This file uses a new mirrorlist system developed by Lance Davis for CentOS.

# 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.
