在虚拟机上安装的CentOS,估计是网络配置问题,导致yum update和yum install之类的功能的用不了.出现标题上面的错误. ifdown [network_adapter] ifup [network_adapter] yum update 尝试以上命令就可以解决了. reference:http://stackoverflow.com/questions/20816133/pycurl-error-6-couldnt-resolve-host-mirrorlist-centos…

这个错误引起主要是因为环境读取不到yun引起的可以考虑/etc/sysconfig/network-scripts/ifcfg-eth0 配置出错导致网络不通.或者/etc/resolv.conf的DNS配置出错.或者可以考虑清楚yum缓存影响(yum clean all) vi /etc/resolv.conf nameserver 202.106.0.20(今天又出现此错误,这个nameserver加进去就好了.记得配置静态ip的话DNS也需要加入 然后update yum试试成功就OK了)…
