先临时设定ip，然后登陆上去
root@ubuntu:~# ifconfig eth0 10.11.12.2/24

root@raspberrypi:~# vim /etc/network/interfaces

#auto eth0
#allow-hotplug eth0
#iface eth0 inet manual

auto eth0
iface eth0 inet static
address 10.11.12.19
netmask 255.255.255.0
gateway 10.11.12.13
dns-nameservers 180.76.76.76 223.5.5.5



auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

auto wlan1
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
root@raspberrypi:~#



重启网络
root@ubuntu:~# ifdown eth0 && ifup eth0

或者：
root@raspberrypi:~# /etc/init.d/networking restart


测试
root@raspberrypi:~# ping www.baidu.com
