CentOs6 Yum 源失效 404[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

今天下午想装点东西。。 突然发现所有的6 yum源都失效了 

YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
 Eg. Invalid release/repo/arch combination/
removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/6/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base

http://mirrors.aliyun.com/centos/6/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 – “The requested URL returned error: 404 Not Found”
Trying other mirror.

不管是阿里 163 清华 都只剩一个readme  去官方一看  官方都没了，估计不支持6了吧， 一顿好找 终于找到一个网站还提供yum源

1、修改yum的fastestmirror.conf

# sed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf

2、备份原来的yum源文件

# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

3、下载新的yum源文件 

# curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo

 4、刷新yum缓存

# yum clean all && yum makecache

加一个epel的 直接补进repo文件就行
