How to Host a DayZ Server (2026 Setup Guide)
DayZ's whole point is persistence — bases, tents and vehicles that survive restarts and updates. Here's how to get a DayZ server running with the right map, RAM tier and mod list without risking the world state your community has built.
Pick your map at signup — Chernarus, Livonia or Sakhal — knowing you can change it later in serverDZ.cfg. Chernarus is the default vanilla experience; Livonia and Sakhal change the terrain and loot economy enough that it's worth deciding with your group first.
Size RAM for how modded your server will get, since DayZ keeps its whole world state in memory. Roughly 6GB covers a small vanilla Chernarus server, 8GB a modded one, and 12–16GB a high-population modded server with a large base count.
Add workshop mod ids to the server's mod list before launch day. The server pulls them from Steam on the next boot — mods that need client-side keys, like map packs, require your players to subscribe to the same mods.
Treat storage_1 and the profiles directory as the thing that actually matters. Both live outside the game files that get re-downloaded on an update, and both are part of every backup — that's why an update or reinstall doesn't cost your community its bases or characters.
Always restart gracefully, never hard-kill the process. DayZ writes persistent state periodically and on a clean shutdown, so a graceful stop from the panel is the safest way to reboot — and it's the path panel restarts already use.
