Remoted in. Issue possibly appeared from an Ubuntu update. Essentially, however, the services were not able to start because PHP was missing the mysqli extension. I suspect it was removed (or at least unlinked) during one of these OS updates. Cleaned up/fixed this by editing the /opt/fog/.fogsettings file and removing the php_ver, php_verAdds, and packages lines. Reran the installer and everything needed installed properly and the services all appear to be working properly too now.
