Nginx web server

[kizniche]

This is a continuation of #305

With v5.5.0 about to be released, there has been one issue holding it back, and that is Apache2 returning a 400: Bad Request error when a backup file/database is uploaded from the Export/Import page.

This wasn't an issue all throughout testing. It was working flawlessly. Then, last night when I was about to make a release, I went to the Export/Import page and tried to restore a database and it gave that error. I spent many hours trying to diagnose the issue, without success.

With that, I think I'm through with Apache2 and would like to attempt to get the Flask frontend running on nginx+wsgi. Previously I was unable to get this working. However, I just recently was able to get nginx running the app. Below is how I did that.

Install Mycodo normally according to the instructions in the README, then create ~/Mycodo/wsgi.py with these contents:

from mycodo.start_flask_ui import app

if __name__ == "__main__":
    app.run()

Activate the virtualenv and start the server:

source ~/Mycodo/env/bin/activate
uwsgi --socket 0.0.0.0:5000 --protocol=http -w wsgi:app

Go to http://IP-ADDRESS:5000 and the frontend loads

I'll be working on this and determining if it's stable and if this should be the default web server of 5.5.0 and onward.

So far nginx appears much faster than apache2

I haven't been having success with the uwsgi module, but when I just tried gunicorn from this tutorial I was able to get the mycodo frontend working! Details to come.

Congrats! nginx runs circles around apache2 performance.

So far I've enjoyed working with nginx. I haven't had any issues so far and it appears faster. I'd like to do a side-by-side speed comparison with pre-4.4.19 and 5.5.0 with the profiler I made a while back to analyze page loading times (back when Mycodo pages took sometimes up to minutes to load, I needed a way to test my code improvements).
