Puma rails server not starting in Daemon mode on EC-2

I want to run Rails application on EC-2 machine.When my SSH session terminates the rails server shutdown.So i want to run the rails server in the background .I used rails s -d command to run rails daemon mode. But it seems like Puma is not started .This is the message i receive and after that process terminates.

Booting Puma => Rails 5.0.6 application starting in development on http://localhost:3000 => Run rails server -h for more startup options

Usually when i run rails server i get => Booting Puma => Rails 5.0.6 application starting in development on http://localhost:3000 => Run rails server -h for more startup options Puma starting in single mode... * Version 3.11.0 (ruby 2.3.5-p376), codename: Love Song * Min threads: 5, max threads: 5 * Environment: development * Listening on tcp://0.0.0.0:3000 Use Ctrl-C to stop

So i guess rails server is not starting..
