CentOS 修改yum源为国内源

CentOS 修改yum源为国内源

修改yum源的方法有两种，很多朋友喜欢修改yum.repos.d这个文件进行更改，deepvps感觉这个方法不是太好，以下这个方法就方便多了。

在CentOS系统中，可以直接通过yum来安装组件，但系统默认的yum源速度往往不尽人意，都连接海外的，为了在国内达到快速安装的目的，就要需要修改yum源，可以使用
http://mirrors.163.com/   http://mirrors.sohu.com 这2个国内源。

执行以下命令就可以了

cd /etc/yum.repos.d

mv CentOS-Base.repo CentOS-Base.repo.bak

wget http://mirrors.163.com/.help/CentOS-Base-163.repo
或

wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
运行yum makecache生成缓存

搞定。

更改centos yum 成中国镜像加快yum速度

163的开源镜像地址 http://mirrors.163.com/.help/CentOS-Base-163.repo
不同版本见http://mirrors.163.com/.help/centos.html


sohu的开源镜像地址 http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
不同版本见http://mirrors.sohu.com/help/centos.html

中国科技大学 http://centos.ustc.edu.cn/CentOS-Base.repo
不同版本见 http://lug.ustc.edu.cn/wiki/mirrors/help/centos (亲试ok)

如果使用上面YUM源的话,最好把里面的 mirrorlist 注释掉,否则系统会启动 fastesmirror 插件自动检查的,并不一定会使用这个yum源的.

我用的是中国科技大学的速度不错。

法一：直接下载源文件

CentOS USTC mirror 这个镜像不错，大家更新可用这个

#yum -y install wget

#cd /etc/yum.repos.d

#mv CentOS-Base.repo  CentOS-Base.r
4000
epo.save

#wget http://centos.ustc.edu.cn/CentOS-Base.repo
注意：如果为第一次安装的新系统的话，则需要先安装wget这个下载软件，不然没有办法下载ＣentOS-Base.repo这个文件的。

法二：手动创建源文件

更改yum镜像站点为中国站点地址,推荐http://centos.ustc.edu.cn/centos/。(中国科技大学)

#cd /etc/yum.repos.d/

#mv CentOS-Base.repo CentOS-Base.repo.bak

#vi CentOS-Base.repo

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

使用说明

首先备份CentOS-Base.repo

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

下载对应版本的CentOS-Base.repo, 放入/etc/yum.repos.d/

这是CentOS 5的:

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.
