Running python script in background?

Question

PHP

Good evening! The essence of the problem.
There is a php script that communicates with another server via SSH using the phpseclib library.
There was a need to run a python script on a remote server from SSH.
I wrote this code, and I thought that everything would be ok:

$ssh->exec("nohup python ./script.py --params=1  >/dev/null 2>&1");

But, the script from which I send this command hangs, waiting for the execution of this command on the server. The python script itself can be executed for days, that is, I will not wait for an answer.
how to build a command that does the same thing (runs a script in the background, allows you to close the connection), and does not make php wait for a response. I hope I made it clear, if anything, I'm always ready to add.

Answer 1

Usually they do this in the console:
ssh [email protected]_ip 'you command &'
And that's it & puts the command in the background, ssh returns control

Answer 2

Try using screen as a layer, or in your case, you need to run another script that will already run nohup python ./script.py --params=1 >/dev/null 2>&1

Answer 3

If in shell terms, then you need to do this:
ssh host "/path/to/python/script.py & bash" Translate
into python yourself)
