问题：反正就是没办法实现源配置的意思吧，我是新人，一头雾水，百度无结果
解决：CentOS 7 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 或者 curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 。
https://opsx.alibaba.com/mirror?lang=zh-CN 在阿里的镜像网站里面看漏了一行，这个版本是可以尝试 curl。
