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

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

If it was your first time setting SECRET_KEY_BASE, eg. unresolved tech debt since Rails 4.1 that this was introduced, how would you set it without causing your production users to have their cookies invalidated and become signed out?
