If you have created your app then got to your rails directory and run “script/server”
If app is not craeted then run “rails demo”, it will create a rails app named with demo

Also, before running command “script/server”, run rake db:migrate in demo directory path to populate the DB but you need to create teh db first if using Mysql or Postgresql.
