Unable to start basic Rails application in Production

I am extremely new to both Rails and WebFaction and unfortunately am unable to get my Rails application (version 3.2.3) to run in Production mode.

I followed your guide as best I could to get it running in production mode with the only result being the unhelpful “We're sorry, but something went wrong.” message when I try to access the page in a browser.

The log in /home/username/webapps/app_name/rails_app_name/log is empty, and the one in /home/username/webapps/app_name/nginx/logs only shows undecipherable information like this:

cache: [GET /] miss
2012/08/19 05:43:01 [emerg] 27972#0: bind() to 0.0.0.0:42806 failed (98: Address already in use)

2012/08/19 05:43:01 [emerg] 27972#0: bind() to 0.0.0.0:42806 failed (98: Address already in use)
2012/08/19 05:43:01 [emerg] 27972#0: bind() to 0.0.0.0:42806 failed (98: Address already in use)
2012/08/19 05:43:01 [emerg] 27972#0: bind() to 0.0.0.0:42806 failed (98: Address already in use)
2012/08/19 05:43:01 [emerg] 27972#0: still could not bind()

If I reconfigure the nginx.conf for the app to run development mode, it works perfectly.

Update:

Ok, so after more experimenting I think that the root of my problem is that I am unable to get rails to properly setup the WebFaction database (the reason it was running fine in development mode was that I had accidentally uploaded the development.sqlite3 file from my local machine).

If I try to run rake db:migrate on the development account it gives the following message:

(it gives a similar error if I try to run any rake db command)
