First Steps
Click the Servers button at the top right of the title bar to start Apache and MySQL, the default GroupStart web and database servers. The startup status of each server is shown in the left column of the Servers & Services section. A check mark next to a server/service indicates that it will be started or stopped when the Servers button is pressed. The Apache web server (the default web server) uses port 8888 by default. This port must be specified when calling the local web page in the browser, e.g.: http://localhost:8888
If you have just upgraded from MAMP Free, you probably already have one website on your local host. To create additional sites, you should create additional hosts. You should have one host in your host list for each website you create.
