[Koha] Koha on VPS?

Good morning I am setting up a new instance of Koha on my own server, a VPS situation with Debian 10. I have gone through the steps, edited /etc/koha/koha-sites.conf and have tried to experiment with editing /etc/hosts, but to no avail. I have also set up a subdomain with the place that manages my DNS and have looked all over the webs for examples of doing what I am trying to do. No success yet I could use a little guidance. I know many people in this group will have implementations of koha on various public facing server situations. thank you -- Jesse A Lambertson Libraries and Technical Services About Me <https://about.me/jesse.lambertson>
