1.ubuntu在啟動(dòng)網(wǎng)卡的時(shí)候出現(xiàn)reconfiguring network interfaces.如果ping不通外網(wǎng)那么說(shuō)明配置的網(wǎng)卡錯(cuò)誤了，重新檢查下網(wǎng)卡配置.

2.dns配置sudo vi /etc/resolv.conf

nameserver 114.114.114.114

nameserver 8.8.8.8

3.ip配置sudo vi /etc/network/interfaces

iface eth0 inet static

address 你的IP

gateway 192.168.0.1

netmask 255.255.255.0

3.ubuntu的基本網(wǎng)卡配置就如所上.centos略有不同,要求大寫(xiě),有等號(hào),ip配置項(xiàng)為IPADDR.
