1. 用nano打开WiFi密码配置文件

root@raspberrypi:/home/pi# sudo nano /etc/wpa_supplicant/wpa_supplicant.conf 

  GNU nano 2.2.6       File: /etc/wpa_supplicant/wpa_supplicant.conf                    

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=GB

network={
        ssid="blizzard"
        psk="inspur88"
        key_mgmt=WPA-PSK
}
