Deploying Rails App to EC2 using Rubber: 503 Service Unavailable

Question

So I've been working on my first (real) rails app for the last couple of weeks and yesterday I tried to deploy it to Amazon EC2 using the Rubber gem. Before I deployed my actual project I said to myself: let's try out rubber on a completely fresh and simple project just to see if it works. After executing the steps in this [railscast][1] everything worked with the simple project. So I tried to deploy my real project executing the same steps as before. Rubber executed all the Capistrano scripts and everything appeared to go well. But when I'm trying to access the website I'm getting this error: 503 Service Unavailable

I used the rubber template "complete_passenger_postgresql". The rubber settings between the simple project that I successfully deployed and the real project are basically the same. The difference is in the actual content of the app.

After reviewing the log files I came accross those errors:

Could it be that the gem "Ancestry" might be causing this problem? And what about the "Permission Denied" errors?

Thanks so much for your help!

Answer 1

I managed to solve the above mentioned problems the following way:

First I gave the rails project's directories & files proper rights by applying

sudo chmod -R 777 ProjectDirectory

This solved the Apache permission error. The reason why this problem occured was the fact that I created the project on another windows and linux machine and tried to deploy it on a mac. The simple test project worked because I created it on the same machine on which I deployed it.

Next I added the following line of code into my see.rb file to get rid of the "uninitialized constant ActiveRecord" error:

require 'active_record'

After those adjustments I deployed everything once again using rubber and it's working :-)
