linux 配置静态IP

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

有些朋友一直在问如果配置网络，就简单写写吧，希望能帮助到大家

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
