Question

..$ rails s
=> Booting WEBrick
=> Rails 4.0.4 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=>         


        

Answer 1

Open the path/to/your/rails/project/tmp/pids/server.pid file.

Copy the number you find therein.

Run kill -9 [PID]

Where [PID] is the number you copied from the server.pid file.

This will kill the running server process and you can start your server again without any trouble.
