I have seen a bunch of people talking about this mod on a server ... I am currently running one, here is what I did ...
1) Follow the steps as if for single player, including clicking compile mods in the mod launcher.
2) Copy all the folders in the main 7 days directory into the dedicated server directory, overwrite as needed. To be clear here this means I copied: _CommonRedist, 7DaysToDie_Data, addons,CompiledMods,Data,EasyAntiCheat, and Mods folders, along with everything in them, into the directory I was running my dedicated server from. I do NOT know how many of these directories and related files were actually necesary, but it seemed like the easiest answer.
3) Set the server config file up however I wanted (name, loot spawnr ate, etc.). Make sure easy anticheat is off. I believe it will not run if easy anti cheat is on.
4) run the dedicated server.
Each player has to set their client up per the rules on the OP for this mod. I know this works as I have around 10 players, maybe more, who play off and on, and around 4 to 6 who play regularly on my server. The server is NOT hosted at some random online company that offers servers. I know a guy who has a server machine in his house and the correct internet to permit server hosting. He hosts the hardware, I remote in and setup/manage the server.
I hope this helps all of you out there who are trying to run this on a dedicated server.
