//启动WiFi
ifconfig wlan0 up

//关闭wifi
ifconfig wlan0 down

//搜索可以连接的wifi
iw dev wlan0 scan |grep SSID

//wpa_passphrase 设置 wifi 名字和密码
wpa_passphrase name passward>> /etc/wpa_supplicant.conf

//初始化 wpa_supplicant
wpa_supplicant -B -iwlan0 -c /etc/wpa_supplicant.conf

//连接wifi
iw wlan0 link

//获取 WiFi IP 地址
udhcpc -i wlan0

//wifi连接后ping外网测试
ping -I wlan0 www.baidu.com

设置开机自启动WiFi
systemctl enable wpa_supplicant@wlan0.service

将 wpa_supplicant.conf 改成 wpa_supplicant-wlan0.conf 并拷贝到新建的目录下
/etc/wpa_supplican

去除开机自启动连接WiFi
rm -rf /etc/systemd/system/multi-user.target.wants/wpa_supplicant@wlan0.service
