yum安装软件时出现如下错误
https://mirrors.aliyun.com/centos/6/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found" Trying other mirror.
临时解决办法
vim /etc/yum.repos.d/CentOS-Base.repo 将其中的 baseurl=…… 换为 baseurl=https://mirrors.aliyun.com/centos/6.8/os/x86_64/
至于什么原因，暂时还不清楚
PS:不到一天的时间，再次使用阿里源，竟然又好了
