Reboot desktop? Open your local host? If you want to do web development you should get familiar with basic computer terminology, at least to a point when you are able to make questions that make a minimum sense.
I'll assume you have installed a bundle that includes the Apache web server and you want to configure a virtual host that's served when you load http://emdaemon
in your web browser. The exact details to do so vary slightly depending on your platform. Being a newbie, I suggest you reuse the main site that's already configured and can be loaded through http://localhost
. It's roughly explained at http://www.wampserver.com/en/presentation.php. Leave multiples sites for the future :)
