How to properly run telegram bot on ssh server?

Question

Python

I wrote a telegram bot in python and uploaded it to VPS. I connect to VPS like this - ssh [email protected]. I run my script python3 main.pyand it works. But as soon as I close the terminal with ssh connection the script stops working. How can I make the script run continuously, without stopping, regardless of whether I am connected to the server or not? What solution is suitable so that I can run several scripts on the server at once?
Server on ubuntu.

Answer 1

Write a service to run the bot:

cat > /etc/systemd/system/foobar.service << EOF

[Service]
WorkingDirectory=/home/user/foobar
User=user
ExecStart=/usr/bin/python3 main.py

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable foobar
systemctl start foobar
systemctl status foobar

Answer 2

When you close the terminal on your computer, the process that was launched in it ends.
Therefore, you need to run the bot in the background. Lots of ways...let it be screen
Keyboard shortcut CTRL A then D
You can close the terminal
screen -r mybot- to open it the next time you log in

Answer 3

try python3 main.py &.

Answer 4

screen!
But in general run the demon!
