Hello @EdDowgiallo and welcome to the community 
i think you are mixing things up here 
SonarType Nexus is not the same thing as SonarQube.
looking at the startup command you should head over to the folks at SonarType to help you.
If you want to setup SonarQube i would need you to clear the logs of the other services and explain to me what you already tried, as SonarQube can be started with systemd, but only with manual configuration.
Hope that helps
