Run Python Flask Server Application in Background

Install gunicorn on ubuntu with below command:

sudo apt-get install gunicorn

With gunicorn, you can create multiple processes to handle client requests.

gunicorn -w 15 -b 0.0.0.0:3000 server:app — daemon

Options Explained:

• w: number of worker processes
• b: IP address and port number to bind on which requests will be handled.
• server:app , If server.py is file name and flask is initialized as ‘app’ in it, then we need to pass it like serverfilename:appname.
• daemon: to run in background
