Rails, Missing `secret_key_base` for 'production' on Ubuntu with unicorn and nginx

Question

I'm trying to run my rails app on Ubuntu for the first time using nginx and unicorn. My question is, when I look at my log, I see the following error.

`app error: Missing `secret_key_base` for 'production' environment, set this value in `config/secrets.yml` (
RuntimeError)`

I looked at my secrets.yml which looks like,

...    
production:
      secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

...

When I type echo $SECRET_KEY_BASE on my command line to check to make sure that the key is set, I get a secret key, which seems to indicate that the key is correctly set. What is missing here?

Answer 1

Your unicorn process runs as root. however you probably set your key with non-root user.
To fix this problem, I recommend you to use dotenv(https://github.com/bkeepers/dotenv).
