You now have a 'myfirstrailsapp' subdirectory that contains a complete directory tree of folders and files that make up an empty Rails web application. Now, run this Rails application. Change to the 'myfirstrailsapp' directory and run the following command:

C:RORmyfirstrailsapp>ruby scriptserver
=> Booting WEBrick...
=> Rails application started on http://0.0.0.0:3000
=> Ctrl-C to shutdown server; call with --help for options
[2006-12-03 17:11:15] INFO  WEBrick 1.3.1
[2006-12-03 17:11:15] INFO  ruby 1.8.2 (2004-12-25) [i386-mswin32]
[2006-12-03 17:11:15] INFO  WEBrick::HTTPServer#start: pid=3304 port=3000

Your Rails application is now up and running on your local machine, on port 3000. WEBrick is a Ruby-based web server that is bundled with Rails and runs on port 3000 by default. Point your web browser to http://localhost:3000/ and you will see your empty Rails application up and running:

The one thing you may have noticed is that you have not written a single line of code, yet you have a running (empty) web application. With other web application frameworks in languages such as Java, .NET (C# and VB.NET), and PHP, you would need to create directory structures, configuration files, and other web application artifacts. That is the beauty of Rails; it does most of the initial setup work for you, leaving you with the task of writing your application and business logic.

Conclusion

This article has provided a brief introduction to Ruby on Rails. We showed you how to get up and running with Ruby on Rails in a short time. In Part 2 of this article, you will connect your web application to the MySQL database and add CRUD (Create, Read, Update, and Delete) support to the web application.
