centOS5的较快yum配置(国内)

Alvinz

今天中午花了两个多小时用硬盘安装盘升级centos4.2到centos5.0，后来一直在寻找新的yum配置，网上一直找不到，最后自己改写了一些代码，服务器是sjtu的，国内的还比较快。

首先，由于直接升级，/etc/下出现了一个新的yum.conf.rpmnew，同时/etc/yum.repos.d/出现新的CentOS-Base.repo.rpmnew，实际旧的两个配置还是保留了，这两个是新的yum配置文件，首先把这2个覆盖旧配置。

1. 
   
2. #cd /etc
   
3. #cp yum.conf.rpmnew yum.conf
   
4. #cd /etc/yum.repos.d
   
5. #cp CentOS-Base.repo.rpmnew CentOS-Base.repo
   

复制代码

需要注意的是，在yum.conf中启动了plugin支持，如果原来安装了旧的插件比如寻找最快源yum-fastestmirror，用在centos5中可能就会出错，所以必须先卸载或者把yum.conf中的plugin支持去掉，安装新的centos5的这个插件。

我的CentOS-Base.repo配置如下（sjtu的mirror，某些注释没去掉）：
