配置网络

```
root@raspberrypi:~# sudo nano /etc/dhcpcd.conf

#配置网卡IP
interface eth0
static ip_address=192.168.1.218/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64
static routers=192.168.1.1
static domain_name_servers=192.168.1.1 8.8.8.8

#配置无线网卡静态IP
interface wlan0
static ip_address=192.168.1.118/24
static routers=192.168.1.1
static domain_name_servers=114.114.114.114

root@raspberrypi:~# sudo nano /etc/sysctl.conf

#禁用IPv6
net.ipv4.ip_forward=1
net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1
```

静态IP配置
```
#修改/etc/network/interfaces文件
iface eth0 inet static

address 192.168.1.88
netmask 255.255.255.0
gateway 192.168.1.1

#修改DNS
root@raspberrypi:~# sudo cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 208.67.220.220
nameserver 208.67.222.222
nameserver 10.10.10.10
```

查找WIFI

```
root@raspberrypi:~# sudo iwlist wlan0 scan

root@raspberrypi:~# sudo iwlist scan | grep ESSID
eth0 Interface doesn't support scanning.

lo Interface doesn't support scanning.

ESSID:"TP-LINK_98C0"
ESSID:"404"
ESSID:"CMCC-qVYW"
ESSID:"ChinaNet-304-5G"
ESSID:"ChinaNet-304"
ESSID:"fcx"
ESSID:"Tenda_479220"
ESSID:"Honor 10"
ESSID:"@PHICOMM_BC"
```

配置无线网络

```
root@raspberrypi:~# sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=CN

network={‌‌
#你的无线网络ssid
ssid="xxxxxx"
#你wifi的密码
psk="xxxxxxxx"
key_mgmt=WPA-PSK
priority=1
}
root@raspberrypi:~# ifconfig wlan0
# 重启网络
root@raspberrypi:~# sudo /etc/init.d/networking restart
```

连接WiFi

```
root@raspberrypi:~# sudo ifup wlan0
root@raspberrypi:~# sudo ifdown wlan0
