Ghost installation removed (without ghost uninstall)


I’m looking into migrating my Wordpress over apache to Ghost/Nginx, and while testing, i removed the ghost directory which was working without using the ghost uninstall.

I’m aware that now I need to remove manually the MySQL user/database. But I’m concerned about Systemd or other orphan configurations that could be existing in the server and could raise issues in the future. There is some kind of checklist/thing to look into in this situation?

Many thanks for your time,
