Service Unavaliable

Question

I downloaded Lamp and am trying to install Craft CMS, but I keep getting a "Service Unavailable- Our site is temporarily unavailable. Please try again later." In the log file it printed the following:

******************************************************************************************************

Does anyone know why this might be happening?

Answer 1

You'll get that message if Craft isn't installed and you hit the front-end of the site.

You'll want to load the control panel for the installer to trigger as noted in Step 5 of the install docs.
