How to use WSGI with a Python/Flask App -- HasGeek Lastuser?

Question

I am trying to setup a lastuser OAuth server on my machine. So I intend to setup Nginx with SSL ( on 443 ) and lastuser app as WSGI server.

HasGeek lastuser

I have setup HTTPS/SSL with Nginx and it works fine on my machine.

However the WSGI server is not working.

Lastuser is basically a Flask app with a WSGI script website.wsgi.

import sys
import os.path
sys.path.insert(0, os.path.dirname(__file__))
from lastuserapp import app as application, init_for
init_for('production')

I tried using gunicorn for WSGI and I get the error ImportError: No module named wsgi as shown below:

$ gunicorn -b localhost:7000  website.wsgi

    __import__(module)

So my question is: is there anything I am doing wrong or is it an issue with gnunicorn or the libraries installed on my machine?

Answer 1

Gunicorn is looking for a wsgi module inside a website module, which does not exist. This is why there is an identical website.py file in the same folder. Call that instead (without the .py extension).

website.wsgi is for use with Apache's mod_wsgi since that expects a .wsgi extension.
