更改yum镜像站点为中国站点地址

使用yum安装软件,升级系统是非常方便的。但如果网速不行,或在学校(就像首师大)访问国外网成问题的,升级起来慢死。这样,最好更改yum镜像站点为中国站点地址,

很多人选择CentOS源于他的开源、免费、可升级。我选择他最看重最后一点—可升级。开源不用说,linux嘛;免费,哈我是一个提倡盗版者;可升级这点可就是CentOS的绝对优势了,你可以像使用正版红帽一样!I love Red Hat,So I love CentOS.

    闲话少叙,奔主题。使用yum安装软件,升级系统是非常方便的。但如果网速不行,或在学校(就像首师大)访问国外网成问题的,升级起来慢死。这样,最好更改yum镜像站点为中国站点地址,这里推荐[url]http://centos.ustc.edu.cn/centos/[/url]。中国科技大学的镜像站点。(瞧人家多NB,人家那也是大学,再看…)。

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

    如下:

# 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.

#

简单的说就是把mirrorlist注释掉,将baseurl改成ustc.edu.cn的镜像地址。

我实验没问题,有问题希望交流。
