开机启动：

vim auto-start-cpu.sh

#!/bin/bashcd /home/pi/alex/code/python cpu.py &

sudo chmod a+x auto-start-cpu.sh

sudo vim /etc/rc.local 在exit 0前加上

/home/pi/alex/code/auto-start-cpu.sh start

exit 0

ps aux | grep cpu.py 可以查看进程

pi@raspberrypi:~/alex/code $ ps aux | grep cpu.py
pi 1462 7.0 1.4 16288 12616 pts/0 S 21:57 0:00 python cpu.py
pi 1468 0.0 0.2 4276 1848 pts/0 S+ 21:57 0:00 grep --color=auto cpu.py

kill -s 9 2389 可以杀掉进程

检查是否已经上传：vim curl_yeelink.sh

#!/bin/bash
curl --request GET --header "U-ApiKey:cfcaf1bbcff8559b6f1e9ba2ed3xxxa" http://api.yeelink.net/v1.0/device/344133/sensor/383211/datapoints

pi@raspberrypi:~/alex/code/cpu_temp $ ./curl_yeelink.sh
