ubuntu dns 解析失敗

由於最近切換過幾回網絡，致使虛擬機ubuntu打不開網頁，

首先測試了能夠ping通外網ip，肯定是DNS解析的問題，上網查到以下解決方法。驗證有效。

 

> sudo vim /etc/resolv.conf

nameserver 223.5.5.5
nameserver 114.114.114.114
nameserver 8.8.8.8
nameserver 10.1.30.1

> sudo /etc/init.d/networking restart
[ ok ] Restarting networking (via systemctl): networking.service
