Verifying Rails Installation

When you install the Rails framework, you also get a new command-line tool, rails, which is used to construct each new Rails application that you write. The rails command creates the right directory structure for you and populates it with some standard Rails code.

We shall create a very small web application to verify our Rails installation.

Open a command window and navigate to a place in your filesystem where you would want to create your application's directory structure. I am creating it in a folder called work and the path on my machine is c:/rails/work Switch to the work folder and use the rails command to create an application called demo, as follows.
c:/rails/work>rails demo

The command has created a directory named demo. Within the demo folder there are many other folders and files created for you. Amongst all of this, you will find a folder called script, that contains some utility scripts that we will be using as we develop our application. For now, we will use the server script that starts a stand-alone web server that can run our newly created Rail application under WEBrick (this is a pure-Ruby web server that comes along with Ruby). So type the command:
c:/rails/work/demo>ruby script/server

We have just started a web server at port 3000. We can now access the application by pointing a browser at http://localhost:3000
You can press control-C to stop WEBrick.
