Setting Up CKAN on AWS - 500 Internal Server Error

Question

I'm trying to set up a basic CKAN site on AWS using the directions posted here: https://github.com/okfn/ckan/wiki/How-to-Install-CKAN-2.0-from-source-on-Ubuntu-12.04-on-EC2#create-ckan-users

After working my way through the tutorial, I'm sitting here staring at a 500 Internal Server Error page. Bummer.

I'm new to using Python for web applications and don't really understand wsgi scripts yet, so forgive me if I'm missing something obvious. Here's a traceback from my error log. Any hints about where I should be looking would be much appreciated. Cheers.

Answer 1

This mailing thread seems to be the answer . (I found it by googling for parts of the traceback.)

Your logging configuration in your configuration ini file. The logging args need to look like this apparently:

args = ("/var/log/ckan/[yoursite.com]/ckan.log", "a", 20000000, 9)
