虚拟机突然访问不了百度了, 查看发现网络都是好的
[root@zk02 ~]# ping ping: : Temporary failure in name resolution
经查修改下如下配置文件即可
[root@zk02 ~]# vim /etc/resolv.conf
添加如下内容：
nameserver 8.8.8.8
然后重新试下，访问正常.
[root@zk02 ~]# ping PING www. (39.156.66.18) 56(84) bytes of data.64 bytes from 39.156.66.18: icmp_seq=1 ttl=128 time=29.3 ms64 bytes from 39.156.66.18: icmp_seq=2 ttl=128 time=33.5 ms64 bytes from 39.156.66.18: icmp_seq=3 ttl=128 time=33.5 ms
