In order to execute a task background, I use nohup command.

 # nohup python patrol.py &

Everything works well but when I close ssh connection and connect it again, I find the process id does not exist.The python task sends a request to an api every 20 minutes.From the api server console, I find the process still works.However from ps command I can not find the process id
