I have an admin base in a simple SQF that is run from the server and requires very little coding knowledge. Only the ability to follow instruction.
My admin base is pretty centralized. It is in Stary, on the south side of the town, in a field.
Let me know if interested and I can get the install instructions prepared for you, or you can post your server PBO and I'll quickly take care adding the base in for you. I use DZAI instead of Sarge (Sarge AI require more server resources, and is more complex). DZAI can be found here...https://github.com/dayzai/DayZBanditAI.
Open your init.sqf and scroll to the bottom right before this }; <------ before that, then add
 execVM "bases\admin_base.sqf";
Now save your init.sqf.
Create a folder called "bases" in your mission PBO. Put youradmin_base.sqfin there.
Repack your mission PBO & upload to server. Simple. You're done
***If you understand what you're doing beyond a beginners level, I recommend running all custom bases/buildings/addons from the server PBO (AI have a tendency of walking/shooting through buildings ran from the mission PBO aka client side).
***Although adding the Towers lights script or any of these 3 may cause Battleye to throw a bitch fit and kick everyone as the lights turn on. You'll need to understand Battleye filters and editing, which is another headache I am still learning.
