First of all check if your "httpd", the daemon for http is up and running, and make sure is check so it starts with every boot up. To do so you can either use "setup" from the shell or choose the Service Configuration utility from the K menu ->System->Service Configuration.
httpd should be checked ( for which it will ask you to make sure that xinetd is checked )
That will start your web server with every boot up. You may need to configure settings such as start page ( in case you don't want it to be the default page ).
