How to organize the launch of scripts on the server?

Question

Python

There is a VDS server with ubuntu. I want to organize several telegram bots on it, as well as raise the rest service. Advise articles, otherwise the variety of ways is darkness.
Of course, I would like a single system, like this can be done on Flask, but I have never worked with it.

Answer 1

1. Virtual environment for the bot
virtualenv --python=/usr/bin/python3.5 /srv/venv/telegram-bot-1
source /srv/venv/telegram-bot-1/bin/activate
pip install -r requirements. txt
2. Systemd service for bot
/etc/systemd/system/telegram-bot-1.service
