MAMP Interface
When you start MAMP, the main window gives you access to all core controls. Click Start on the toolbar to launch your local servers. The button color shows the current server status:
- gray = servers not running
- green = all servers running
- orange = not all servers running
The web server (Apache or Nginx) starts by default on port 8888, the database server (MySQL) on port 8889. When accessing your site in a browser, append the web server port to the URL, e.g.: http://localhost:8888
