Answer 1

这可能是由两种可能性引起的。

1.回购太老了，找到你的CentOS版本

基地，我试图找到通过link操作系统。从自述文件中获取这些信息。

This directory (and version of CentOS) is deprecated. For normal users, you should use /5/ and not /5.9/ in your path. Please see this FAQ concerning the CentOS release scheme:

https://wiki.centos.org/FAQ/General

If you know what you are doing, and absolutely want to remain at the 5.9 level, go to http://vault.centos.org/ for packages. Please keep in mind that 5.9 no longer gets any updates

在此链接中，建议您通过另一个link找到旧版本。因此，您需要修改CentOS-Base.repo。

将所有http://mirror.centos.org/centos/***替换为http://vault.centos.org/***。

例如：

Original: baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ 
New:  baseurl=http://vault.centos.org/$releasever/os/$basearch/ 

---

2.网络版本

检查mirrorlist server是可访问的。

$ ping mirrorlist.centos.org 

如果您可能遇到下面的错误消息。

ping: unknown host mirrorlist.centos.org 

为了解决这个问题，添加有效域名服务器到resolv.conf（使用须藤如果你不根用户）

$ echo nameserver 8.8.8.8 > /etc/resolv.conf 

Answer 2

这是因为CentOS 5的已过时，需要基地回购文件的手动更新将所有内容指向Centos库。

备份您的/etc/yum.repos.d/Centos-Base.repo

替换为以下将让你再次去：

# CentOS-Base.repo 
# 
# The mirror system uses the connecting IP address of the client and the 
# update status of each mirror to pick mirrors that are updated to and 
# geographically close to the client. You should use this for CentOS updates 
# unless you are manually picking other mirrors. 
# 
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead. 
#
