Topic: how to run rails server on rails 3

I tried to get to localhost:3000 but nothing works. I've heard you can get in by running the rails server, but it never works.
How to run rails server? If not, how to run localhost:3000 please? Thank you.

Re: how to run rails server on rails 3

In the directory of your web app type: rails s

Then goto localhost:3000 in your web browser. You can also try 127.0.0.1 in your web browser is localhost does not work.
