使用gunicorn运行Django：错误请求（400）

Question

I am following this tutorial to set up a Django application and serve it with Gunicorn on a Debian DigitalOcean server: http://michal.karzynski.pl/blog/2013/06/09/django-nginx-gunicorn-virtualenv-supervisor/

I have got as far as the section starting "Now that you have gunicorn, you can test whether it can serve your Django application by running the following command". Now I'm stuck.

In other words, I can successfully run the application using python manage.py runserver , but not by using gunicorn.

I've successfully accessed my app with:

$ python manage.py runserver xx.xx.xx.xx:8000 

Now from the same directory, I'm trying to run:

$ gunicorn my_django.wsgi:application --bind xx.xx.xx.xx:8001

It appears to start OK, but when I go to http://xx.xx.xx.xx:8001 , I see:

Bad Request (400)

I'm not sure how to debug this: there's nothing in /var/log/gunicorn/ .

I have set ALLOWED_HOSTS=['xx.xx.xx.xx'] in my settings file.

UPDATE: Being an idiot: gunicorn was looking in production settings file, not local settings file. Setting the ALLOWED_HOSTS in production settings fixed it.

I'd still really like to know how to debug problems like this though.

The answer: gunicorn was looking in production settings file, not local settings file. Setting the ALLOWED_HOSTS in production settings fixed it.
