ruby script/server is not working

Hi All,

I am using ubuntu. I have installed rails in my computer. And I have installed all the required gems. But while I am starting the server by using the command ruby script/server it is returning the following error. Can anybody give the solution for the problem?

=> Booting Mongrel (use 'script/server webrick' to force WEBrick)
=> Rails 2.2.2 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting

Iam a RoR newbie myself, but I think you cannot start the server without creating a Project.
First create a project.Then, make sure you are in project's directory.For e.g, my project is blog.It is situated in c:\sites.
So, i need to be in c:\sites\blog>
Also, please note that the command to launch the server in Rails3 is
Rails Server
Try it

EDIT:My bad, failed to notice you are running Rails 2 . But still I believe, the creating project to launch server is valid for Rails 2 Also.

santoshkumar is correct, you need to create a project first. With rails 2 that is:

rails yourprojectname

then change directory into your project

cd yourprojectname

and start the server with

./script/server

I have already done the suggestion given by you....

I have created a project and sure I am inside my project only.

I am using rails 2.2.2 only.

Would you walk me through exactly what you are doing to create a new project and start the server?

It looks like a problem with Mongrel.

try typing .script/server webrick.
I'm sure that'll solve the issue
