Re: ec2 using bitnami djangostack: application never loads; browser just hangs

Thanks. I've checked apache's error_log, and it doesn't report anything unusual. The access_log reports about four hundred GET requests that look sort of like this:

10.73.205.233 - - [22/Jan/2014:18:07:34 -0500] "GET /img/ami-lower-container.png HTTP/1.1" 304 -

10.73.205.233 - - [22/Jan/2014:18:07:34 -0500] "GET /img/ami-list-item.png HTTP/1.1" 304 -

The last two lines are:

201.249.174.162 - - [22/Jan/2014:18:09:19 -0500] "HEAD / HTTP/1.0" 200 -

120.192.101.153 - - [22/Jan/2014:19:21:28 -0500] "GET /manager/html HTTP/1.1" 404 210

I don't know what other logs to check. When I run the app in DEBUG=True, I don't see any difference. If I introduce an artificial bug in /mysite/mysite/urls.py, it reports the bug through the Django debugging page (and also in error_log). But when I remove the bug, it's back to endless waiting. How can I tell if the request is making it to modwsgi or it's stuck in apache?

1. Have you checked all of the access logs and error logs when the app is started? Is your request getting served by modwsgi, or is it stuck in apache?

2. Start the application with DEBUG=True in settings, to see if you get any information from the app.

Thats where I'd start.

I used the Bitnami Djangostack AMI to set up a Django environment with apache2 and mod_wsgi on a free instance provided by Amazon's EC2. The django app is installed at /opt/bitnami/apps/django/django_projects/mysite, alongside the default Project application that comes with the stack. The app runs on my local computer on the development server without issue. When I transferred the app to the server, I ran the collectstatic script to copy all of the static files to mysite/static, and configured the server to serve STATIC_ROOT at STATIC_URL (settings and configuration details are reported below). As best I can make out, I've configured everything in accordance with the Django documentation and modwsgi documentation.

When I point my browser to the server's public address, I see the bitnami startup page, but when I point to the subdirectory mapped to the application, the browser just hangs. It acts as if it's loading a website, spins the little wheel to tell you it's loading a website, and says 'Waiting for xx.xxx.xxx.xxx..." But nothing ever happens. There are no errors reported in /opt/bitnami/apache2/logs/error_log. But If I point instead to a random subdirectory that doesn't exist, I get a 404 page. If I point to the static subdirectory, I get a 403 Forbidden page. If I purposefully add a bug to any of the python code (in e.g. mysite/mysite/urls.py or mysite/myapp/views.py), I get a 500 Internal Server Error and a message in the error_log with the expected python stack trace.

If anyone has any suggestions, I would obviously be very grateful. I'm pretty new to this.
