机子可以 ping www.baidu.com 但出现如上错误.是因为yum源的问题.换阿里云的yun源.
换yum源需要用到wget，但大部份centos默认没有wget,又得安装wget,但同样会提示
1 | Cannot find a valid baseurl for repo: base/7/x86_64 |
情况1，默认有wget的服务器,直接参考换源链接即可
1 | mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup |
1 | wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo |
情况2，默认没有wget的服务器
修改 CentOS-Base.repo 配置
1 | vi /etc/yum.repos.d/CentOS-Base.repo |
换成如下阿里云源

找不到代码的话可以直接访问 http://mirrors.aliyun.com/repo
然后就可以更新软件了
1 | yum update -y |
