Rails应用程序部署在Heroku上

Question

I'm new in rails app development I am little bit confusing about rails deployment.

I following this guide below and done at all. That mean my rails app on production mode?

Need to change Puma RACK_ENV to 'production' in Profile before pushing to heroku?

I believe so. The entire tutorial is setting up your rails server to work in production mode. Using some inductive logic, it seems that the tutorial is assuming you're in production:

"Rails 4 no longer has a static index page in production. When you're using a new app, there will not be a root page in production, so we need to create one. We will first create a controller called welcome for our home page to live:"

Indicates to me that it's assuming your rails server will be running in production.

To make doubly sure, you can check the heroku logs and look for a line that says:

Rails [your version] application starting in production
