probably a very newbie-ish question for people who run web servers out there: how do you manage port numbers?
in my case, i'm running this activitypub node, along with a few websites for various projects, all on a vps, with nginx doing the routing between domains and the actual services
so far when i add a new service, i pick a "random" port number by just… thinking one up, and hoping it's not already used
there's got to be a better way, right?
just keep a document with used ports and their services?
or is there a tool that real sysadmins use?
