yum repo centos6.5 ,6.6 可用 repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 2022.7.5留

原因
CentOS 6 于2020年11月30日停止维护，而Yum想要连接旧版本的仓库。所以，我们需要更新陈旧版本的仓库然后指向vault。

解决方案
为了解决这个问题，我们需要修改/etc/yum.repos.d/CentOS-Base.repo，然后替换掉所有镜像源。（注释下面使用的镜像源可能会随着运营商调整而失效，可以点击进入 https://mirrors.aliyun.com/centos-vault/centos 查看还有哪些版本的镜像源有效）

1.进入到 /etc/yum.repos.d/目录

cd /etc/yum.repos.d/

2.备份原文件

cp CentOS-Base.repo CentOS-Base.repo.old

3.编辑新文件

vi CentOS-Base.repo

全部换成下面

# 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.
