由于种种原因,比如需要一直延用过去构筑的系统,或者是为了模拟旧版RedHat Enterprise版(RedHat的收费版,CentOS可以说是它的山寨版)等等,会有需要继续使用旧版的CentOS的情况。

但是由于CentOS的各个服务镜像几乎已经不支持旧版系统的升级升级yum的时候会遇到以下问题。

# yum update
Setting up Update Process
Setting up repositories
not using ftp,http[s],or file for repos,skipping - 4 is not a valid release or hasnt been released yet
Cannot find a valid baseurl for repo: update
Error: Cannot find a valid baseurl for repo: update

提示已经找不到提供升级支持了。但如果又非要继续使用旧版CenOS呢?我们从这里得到了启示。http://mirror.centos.org/centos/4.9/readme 
This directory (and version of CentOS) is depreciated.  

CentOS-4 is now past EOL

You can get the last released version of centos 4.9 here:

http://vault.centos.org/4.9/

对,http://vault.centos.org/还提供旧版的升级,所以我们必须修改配置文件(/etc/yum.repos.d/CentOS-Base.rpeo)来定向到这个镜像站点方法如下

这样一来我们可以正常使用yum update了。

CentOS2,3的情况还没有确认过,理论上都行得通。不过嘛,如果没有特殊情况还是升级你的CentOS吧
