在Ubuntu终端中，如何保持python程序运行？

Question

I recently got my own VPS and intend to run my discord bot off of it. However the main problem I am encountering is when the PuTTY session is closed then the program turns off even though the server remains on.

How can I make the program a process that stays on forever until I choose to end it?

Answer 1

Since you are on ubuntu in a terminal window when you start the python program use the nohup command (man page synopsis):

nohup - run a command immune to hangups, with output to a non-tty

For example:

$ nohup /tmp/a.out /tmp/data
nohup: ignoring input and appending output to 'nohup.out'
$ 

Answer 2

You can run the any script files in background by giving ampersand (&) symbol at the end of file name in terminal.

Example:

sudo filename.py & 

This keeps on running even if you close the putty session.
