Rails missing SECRET_KEY_BASE in production

I have ubuntu server, Rails 5.0 and apache web server Also I have many sites on it

When I add new site, I have an error "Incomplete response received from application"

When I check apache log I see message: 

App 14561 stderr: [ 2017-01-17 21:01:16.5804 14591/0x0000000064e100(Worker 1) utils.rb:85 ]: *** Exception RuntimeError in Rack application object (Missing `secret_key_base` for 'production' environment, set this value in `config/secrets.yml`) (process 14591, thread 0x0000000064e100(Worker 1)):

My config/secrets.yml contains default value:

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

Also I have just setted env variable SECRET_KEY_BASE via writting in a file /etc/profile

I see than via command echo $SECRET_KEY_BASE

Check you have mod_env

sudo a2enmod env

From your rails app [anywhere, does not matter, it's just a random string] run

rake secret
... outputs a big long string ...

Then add to your Apache Virtual Host definition.

somewhere in /etc/apache2/sites-available/*.conf 

<VirtualHost ...>
  SetEnv SECRET_KEY_BASE "thebiglongstringgeneratedbyrakesecret"
</VirtualHost>

Check your work

apache2ctl -t
Syntax OK

restart apache

apache2ctl restart

check it from the command line

curl https://my-server-url -I # or http

Leave a comment if that does do the trick.

First, note that /etc/profile is only sourced when invoking an interactive login shell, so any variables set in this file wouldn't ever get run by a web-server daemon on startup, which is why it didn't work as expected in your attempt.

Since you're using Apache + Phusion Passenger, you can set application-specific environment variables within your Apache configuration files using the SetEnv option of mod_env.

Otherwise, you could set your environment variables from your application code by reading configuration on your application server's filesystem. You could use a gem like dotenv to automate this pattern.

See Phusion Passenger's documentation About Environment Variables: Passenger-Served Apps for a documentation reference.

Depending on how you are starting the server the ENV variables may not be visible.

Have you tried: 

SECRET_KEY_BASE='foo' rails s

Some discussion on environment variables with Rails servers is discussed at How to start Rails server with environment variables set?

Try restarting your server, it might need to be restarted to pick up new changes in your config files.

Your config/secrets.yml file should also have:

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