【Linux使用技巧】修改CentOS的更新源

本文以CentOS5.3的上海交大更新源为例：

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

[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/5.3/os/$basearch/

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#releasedupdates

[update]

name=CentOS-5-Updates

#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=updates

baseurl=http://ftp.sjtu.edu.cn/centos/5.3/updates/$basearch/

#packagesused/producedinthebuildbutnotreleased

[addons]

name=CentOS-5-Addons

#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=addons

baseurl=http://ftp.sjtu.edu.cn/centos/5.3/addons/$basearch/

#additionalpackagesthatmaybeuseful

[extras]

name=CentOS-5-Extras

#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=extras

baseurl=http://ftp.sjtu.edu.cn/centos/5.3/extras/$basearch/

#additionalpackagesthatextendfunctionalityofexistingpackages

[centosplus]

name=CentOS-5-Plus

#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=centosplus

baseurl=http://ftp.sjtu.edu.cn/centos/5.3/centosplus/$basearch/

enabled=0

#contrib-packagesbyCentosUsers

[contrib]

name=CentOS-5-Contrib

#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=contrib

baseurl=http://ftp.sjtu.edu.cn/centos/5.3/contrib/$basearch/

2．校验Key导入：执行

rpm --import http://ftp.sjtu.edu.cn/centos/5.3/os/i386/RPM-GPG-KEY-CentOS-5

3．进行升级：执行

yum update

Ok了，搞定。

小小标注一下：rpm -ivh --aid 是可以安装RPM帮忙解决依赖问题的命令……总是忘……这个和本文无关……
