orangepi PC plus设置开机自启动WiFi断网自动连接脚本

1、nmcli命令配置IP和gateway

nmcli con add con-name JK_AGV ifname wlan0 type wifi ssid JK_AGV ip4 192.168.2.108/24 gw4 192.168.2.1

2、配置password

nmcli con modify JK_AGV wifi-sec.key-mgmt wpa-psk
nmcli con modify JK_AGV wifi-sec.psk JK12345+

 3、配置静态ip

nmcli conn mod JK_AGV ipv4.method manual

4、连接WiFi

nmcli conn up JK_AGV

5、配置/lib/systemd/system/rc.local.service

[Unit]
Description=/etc/rc.local Compatibility
Documentation=man:systemd-rc-local-generator(8)
ConditionFileIsExecutable=/etc/rc.local
After=network.target

[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
RemainAfterExit=yes
GuessMainPID=no

[Install]
WantedBy=multi-user.target
Alias=rc-local.service

 6、WiFi断网自动联网脚本

#!/bin/sh 
while :	
do
	sleep 10	
	gateway=$(route -n | grep wlan0 | grep UG | awk '{print $2}')	
	if [ -z $gateway ];	
	then
			echo "the gateway is null, wlan0 connecting..."	
		nmcli conn up JK_AGV	
	else	
		ping -c 3 -I wlan0 -s 8 $gateway >/dev/null 2>&1	
		if [ $? = 0 ];	
		then	
			echo "wifi is connected"	
		else	
			echo "wlan0 connecting..."	
			nmcli conn up JK_AGV
		fi	
	fi	
	sleep 150	
done
exit 0

 7、配置/etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
bash /root/auto_connect_wifi.sh > /var/wifi.log 2>&1 &
exit 0

 8、创建软链接

ln -s /lib/systemd/system/rc.local.service /etc/systemd/system/
