Using forever.js with Python

Question

Two questions:

• Is there a Python equivalent to forever.js to run a Python process in the background without requiring sudo?
• Is it possible to use forever.

Answer 1

Using python 3 with Flask to run with forever.js, here is my build process

python3 -m venv venv
source venv/bin/activate
sudo -H pip3 install -r requirements.txt
FLASK_APP=app.py forever start -c python3 app.py --port=5001

Answer 2

I was having problems executing a python script with custom logging paths, after trying I got to work with the next command:

 forever start -c python -l /tmp/forever.log -o /tmp/out.log -e /tmp/error.log python_script.py

Tell me if it worked for you

Answer 3

It is easy to use Python with forever.js:

forever start -c python python_script.py

To use it with virtualenv is a little bit more complicated, I did it using a bash script (call it python_virtualenv):

#!/bin/bash
# Script to run a Python file using the local virtualenv
source bin/activate
bin/python $@

Now use that script with forever:

forever start -c ./python_virtualenv python_script.py
