Centos5.5国内更新源

Centos5.5国内更新源

第1步备份yum配置文件，修改yum配置文件。cp /etc/yum.repos.d/CentOS-Base.repo CentOS-Base.repo_bakvi

/etc/yum.repo.d/CentOS-Base.repo可以用中科大

(ustc)yum源，也可以用上海交大(sjtu)yum源，两者只能选一个。用下面的内容覆盖CentOS-Base.repo就行了。#中科大(ustc)yum源，http://centos.ustc.edu.cn/centos/5/就是最新的，#也可以设置成

http://ftp.sjtu.edu.cn/centos/5/os/x86_64/RPM-GPG-KEY-CentOS-5第3步yum update

新配置一个服务器centos5.5，运行yum -y update出现一个警告信息：Total 2.1 MB/s | 643 MB 05:00 warning:

/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 这是由于yum安装了旧版本的GPG keys造成的，解决办法就是rpm --import /etc/pki/rpm-gpg/RPM* 搞定。
