503 means "service unavailable."  Since PHP seems to be available, make sure MySQL is running.

The 503 error that is triggered from that log entry happens when Craft files are in place on the server, but it haven't been installed yet and someone loads the front-end of the website.

Assuming you've set everything else up correctly, you just need to [run the installation wizard](https://craftcms.com/knowledge-base/first-time-setup)!
