现CentOS 6操作系统所设置的Yum源为国内阿里云Yum源仓库，在yum安装时报错如下

Loaded plugins: fastestmirror

Determining fastest mirrors

 * base: mirrors.aliyun.com

 * extras: mirrors.aliyun.com

 * updates: mirrors.aliyun.com

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"

 

因CentOS 6版本在2020年11月30号版本生命周期终止，CentOS Yum上游源已不保留CentOS 6 Yum源，涉及CentOS 6版本分支的Yum源移至http://vault.centos.org/下。

对应国内的镜像源站点访问过期源，如阿里云Yum源-https://mirrors.aliyun.com/centos-vault

 

解决方法:

1.备份 /etc/yum.repos.d/CentOS-Base.repo文件

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

 

2. 设置CentOS Yum源为CentOS 6.10

 

官方过期归档Yum源

http://vault.centos.org/6.10

可选国内镜像源

https://mirror.tuna.tsinghua.edu.cn/centos-vault/6.10

https://mirrors.aliyun.com/centos-vault/6.10

 

新建文件/etc/yum.repos.d/CentOS-Base.repo，将以下内容复制进去

vi  /etc/yum.repos.d/CentOS-Base.repo

 

 

因国内镜像站点HTTPs涉及CentOS yum访问本地证书无法识别，修改为HTTP访问

3.YUM操作验证

 

yum clean all #清除缓存

yum makecache #创建缓存

yum repolist #查看源仓库情况

阿里云 镜像站点CentOS 6 YUM与EPEL源
