阿里云的开源镜像站地址： https://mirrors.aliyun.com/repo/ 在里面可以看到还有Centos-6.repo的repo包，但下载下来执行源更新会遇到问题：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" 后面的其它地址也一样会请求超时。本文地址:http://www.04007.cn/article/1108.html,未经许可,不得转载.

mirrors.aliyun.com镜像中 http://mirrors.aliyun.com/centos/6/os/x86_64/repodata/repomd.xml: 这些地址都无法访问。阿里云在centos镜像站（地址：https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.3e221b1133l0LM ）中也提到centos6（centos6官方源已下线，建议切换centos-vault源）。因为CentOS在有新版本后就会结束对老版本的系统支持，因此对应的yum源也失效了，CentOS官方提供http://vault.centos.org/ 包含了所有发行的CentOS版本，因此需要将yum源修改为centos-vault的源。因此导致yum update报错，无法访问Centos6源。可以将上面Centos-6.repo文件中的 http://mirrors.aliyun.com/ 都换成https://vault.centos.org即可。包括baseurl和gpgkey这两行。如还会报错试着将$releasever替换为当前系统所使用的CentOS版本。对比如下：
