How to set Rails environment?

May 26, 2014 28.3k views
I have a 1-click installation of Ruby on Rails 4, NginX, and Ubuntu running on my droplet. Unfortunately, I haven't found a way to create my production database from my schema.rb file yet. I think this is due to the fact that my Rails environment is still set to "development". When I type "rake about" I get this: Application root /home/rails Environment development Database adapter sqlite3 I would like to set my app to production mode, though. I would also like to use MySQL instead of SQLite. How can this be done? Typing "RAILS_ENV=production" seems to have no effect whatsoever. Thanks for any help.

You need to either run
export RAILS_ENV=production
which will last until your exit your shell (log out), or prepend RAILS_ENV=production to the command you're trying to run, e.g.:
RAILS_ENV=production rake about
OK, thanks! I managed to switch to production mode somehow but don't remember exactly how I did it.

This is pointless, how do we set the environment PERMANENTLY?

Good point. Have you found a solution to this yet?

I personally use a .rbenv-vars file in the root of each Rails project.
There you can set all your project specific env vars and they're going to be automatically loaded by rbenv.
