标题: 最后的CentOs4 yum源
发现一台服务器的yum不能用了：

[root@fm3 yum.repos.d]# yum update yum
Setting up Update Process
Setting up repositories
not using ftp, http, 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

后来在网上找到了一个解决方案：将配置文件CentOS-Base.repo里注释掉的yum源重新启用，即将#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
之类URL前面的“#”去掉。

但实践证明，此方案无效。yum依然报错：

[root@fm3 yum.repos.d]# yum update yum

Trying other mirror.
Error: failure: CentOS/RPMS/yum-2.4.3-4.el4.centos.noarch.rpm from base: [Errno 256] No more mirrors to try.

继续搜索，但没有结果。

后来仔细看了看错误提示，发现这是yum源http://mirror.centos.org/centos/4/不可用所致。于是手工访问http://mirror.centos.org/centos/4/，发现里面没有任何软件包，只有一个readme。点开来一看：

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/

大意是说，此目录已经没有任何价值了，因为CentOS-4已经停止发布了...
后来又试了其他几个yum源：

http://mirrors.163.com/centos/4/
ftp://ftp.nsysu.edu.tw/Unix-like/CentOS/4
http://centos.mirror.cdnetworks.com/4/

发现都是一样的readme，一样的“CentOS-4 is now past EOL”...

难道全世界都找不到一个可用的CentOs 4 yum源吗？

继续baidu，google，还是没有结果...

后来无意中发现，在这个readme里有提供一个centos 4.9的下载链接：http://vault.centos.org/4.9/

打开了一看，发现里面有个CentOS-Base.repo...唔，这不正是CentOs 4yum源的配置文件吗？再入上层目录，发现4.0～4.9各有一个目录，而且里面都有CentOS-Base.repo...

真是柳暗花明啊！，在http://vault.centos.org/这个链接里有一个可用CentOs4 yum源！

于是进入目录4.8（服务器上装的系统是CentOS release 4.8 ），将里面的CentOS-Base.repo下载覆盖至服务器的/etc/yum.repos.d/CentOS-Base.repo，然后重新运行yum...嘿嘿，终于成功了！

http://vault.centos.org/4.8/
