ip配置方法是编辑sudo nano  /etc/network/interfaces

树莓派默认配置

auto lo

iface lo inet loopback

iface eth0 inet dhcp

allow-hotplug wlan0

iface wlan0 inet manual

wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp

修改为静态ip的方法

1，老外的方法

sudo vi /etc/network/interfaces

To change to static IP address

cd /etc/networks

sudo nano interfaces

replace the line “iface eth0 inet dhcp” with

iface eth0 inet static

address 192.168.1.4

netmask 255.255.255.0

gateway 192.168.1.1

You should also take a look at the file /etc/resolv.conf

and check it has a nameserver entry (probably pointing at your default gateway) or direct to your ISP name servers.

nameserver 192.168.1.1

2.国内帖子

1.配置ip地址

编辑sudo nano  /etc/network/interfaces

自动获取ip的配置：

auto eth0

allow-hotplug eth0

iface eth0 inet dhcp

手动配置ip：

auto eth0

iface eth0 inet static

address 192.168.1.7

netmask 255.255.255.0

gateway 192.168.0.254

2.配置DNS

编辑 sudo nano /etc/resolv.conf

domain lan

search lan

nameserver 192.168.1.1

nameserver 192.168.99.100

注：nameserver 后面的ip就是dns服务器，根据自己的运营商情况填吧

电脑与树莓派网线直连

方案1：

on your pc

address 192.168.1.100

netmask 255.255.255.0

gateway 192.168.1.100

on your pi

/etc/network/interface

address 192.168.1.5

netmask 255.255.255.0

gateway 192.168.1.100

方案2：

Rpi

ip 172.16.1.1

mask 255.255.255.0

gateway 172.16.1.2  //172.16.1.1 works too

ubuntu

ip 172.16.1.21

sub 255.255.255.0

gateway 172.16.1.1 //172.16.1.10 works too

方案3：

That worked too.

Don't set the devices to be gateway for each other. All you need is something like this:

IP address of PC: 192.168.1.1

IP address of Rasperberry Pi: 192.168.1.2

Subnet mask on both: 255.255.255.0

Default gateway on both: 192.168.1.254
