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)…

在虚拟机上安装完CentOS6.5之后,首次使用时yum命令安装软件时,出现一堆的” Errno 14 Couldn't resolve host”这个问题. 上网上查了半天,很多都说在/etc/resolv.conf文件末尾添加 nameserver 8.8.8.8 可我试了根本就没有用!才发现网上99.9%的人都是人云亦云的抄来的,根本就没说到点子上.其实这个问题根本原因就是你的CentOS不能连接网络造成的. 你要问我为什么是“百度”?我只能回答:百度当然是用来测试网络通不通用的. 好吧言…
