Getting "Missing `secret_key_base` for 'production' environment" when trying to get Unicorn to work with Rails

Posted on April 10, 2017

Hi,

I’m tryihng to follow your tutorial for installing unicorn and getting it to work with nginx …

https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-unicorn-and-nginx-on-ubuntu-14-04

I have a file in ~/myproject/config/secrets.yml which contains

[code] development: secret_key_base: 547268978521e278fd572db969ce2d25cea9da7c6db4f7164942d02322177128704a4c76ed1f536dd7ac791b10ef0355b1928fb128077657bdef156472ad81

test: secret_key_base: c1aae665f8ed25da55a457870526dcac878d5a3734ab2fd29b4ec32b4b31bbe2f16d3b72bf0ca19286c1c88e4862d35f45c2c10140d990388e5e2184459cd23e

Do not keep production secrets in the repository,

instead read values from the environment.

production: secret_key_base: <%= ENV[“SECRET_KEY_BASE”] %>

[/code]

Yet when I restart nginx and unicorn and attempt to visit my web page, I get this error in my unicorn logs …

What am I missing? What else do I need to do here?

Hi @laredotornado6b
