设置centos5更新源

CentOS 安装完毕，首先应该修改更新源，并升级到最新的系统。

国内速度较快的经常使用更新源：

http://mirror.be10.com/centos/

http://centos.candishosting.com.cn/

http://ftp.sjtu.edu.cn/centos/

http://ftp.hostrino.com/pub/centos/

http://mirrors.ta139.com/centos/

http://ftp.iasi.roedu.net/mirrors/centos.org/centos/

首先备份CentOS-Base.repo，而后再编辑 yum 的配置文件

实例：

1．修改/etc/yum.repos.d/CentOS-Base.repo为:
CentOS-Base.repo
[base] 
name=CentOS-5 - Base 
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch& repo=os 
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ 
baseurl=http://ftp.sjtu.edu.cn/centos/5/os/$basearch/ 
gpgcheck=1 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

 

 

#released updates 
[update] 
name=CentOS-5 - Updates 
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=updates 
baseurl=http://ftp.sjtu.edu.cn/centos/5/updates/$basearch/ 
gpgcheck=1 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

 

#packages used/produced in the build but not released 
[addons] 
name=CentOS-5 - Addons 
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=addons

 

 

baseurl=http://ftp.sjtu.edu.cn/centos/5/addons/$basearch/ 
gpgcheck=1 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#additional packages that may be useful 
[extras] 
name=CentOS-5 - Extras 
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=extras

baseurl=http://ftp.sjtu.edu.cn/centos/5/extras/$basearch/ 
gpgcheck=1 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#additional packages that extend functionality of existing packages 
[centosplus] 
name=CentOS-5 - Plus 
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=centosplus 
baseurl=http://ftp.sjtu.edu.cn/centos/5/centosplus/$basearch/ 
gpgcheck=1 
enabled=0 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#contrib - packages by Centos Users 
[contrib] 
name=CentOS-5 - Contrib 
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=contrib 
baseurl=http://ftp.sjtu.edu.cn/centos/5/contrib/$basearch/ 
gpgcheck=1 
enabled=0 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

2．执行
64位：
rpm --import http://ftp.sjtu.edu.cn/centos/5/os/x86_64/RPM-GPG-KEY-CentOS-5

32位：
rpm --import http://ftp.sjtu.edu.cn/centos/5/os/i386/RPM-GPG-KEY-CentOS-5

3．执行
yum update

有些朋友可能按照其余的文档作过有时会报错，请检查是否是将“5”写成了“05”！
