运行yum报错Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

今天给Centos通过rpm -Uvh装了个epel的扩展后，执行yum就开始报错： Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again 在网上查了查，解决办法都是编辑/etc/yum.repos.d/epel.repo，把基础的恢复，镜像的地址注释掉 #baseurl mirrorlist 改成 baseurl #mirrorlist
