Raspberry set WIFI via command line

安装的系统版本是 RASPBIAN STRETCH LITE
按照官网上的文档设置完后并不能连接到WIFI.

https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md

在网上查找过相关问题后，找到一种对我有效的解决方案。(步骤2为官网连接介绍的方法）

1. 在 /etc/network/interfaces 中添加

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

2.在/etc/wpa_supplicant/wpa_supplicant.conf中添加

country=CN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="your ssid"
psk="your wifi password"
}
