SteamCMD setup

Install DayZ Dedicated Server with SteamCMD

A reliable DayZ server starts with SteamCMD and the DayZ Dedicated Server app. Use a dedicated install folder, verified app updates and file validation before launch.

DayZ server install SteamCMD DayZ server appid DayZ Dedicated Server update

DayZ server appid: 223350
DayZ Workshop appid: 221100
Experimental server appid: 1042420
Protect mission and profile folders during updates.

serverDZ.cfg

serverDZ.cfg, profiles and launch arguments

Many launch failures come from wrong paths, broken config files or mixed profile folders. Keep each server on its own config, profile path and clean launch arguments.

serverDZ.cfg setup DayZ launch parameters DayZ profiles folder

Important fields: hostname, passwordAdmin, maxPlayers, verifySignatures.
Keep -config, -port, -profiles, -mod and -serverMod consistent.
Server name, port and map should match the web profile.

Mods and keys

Workshop mods, @mod folders and bikey sync

For modded DayZ servers, Workshop download is only the first step. Client mods, server mods, bikeys and launch arguments must stay in sync.

DayZ Workshop mod install DayZ bikey error DayZ -mod -serverMod

Client mods go into the -mod list.
Server-only mods go into the -serverMod list.
Missing bikeys can block player joins.
After mod updates, check the manifest and keys.

Ports and RCON

Ports, Windows Firewall and BattlEye RCON

A public DayZ server needs more than a running process. Game/query ports must be reachable and the RCON password must remain protected.

DayZ port forwarding DayZ server not showing BattlEye RCON setup

Open the required UDP ports in Windows Firewall.
Do not expose the RCON password in public files.
Player lists, broadcasts and admin commands can run through RCON.
After port changes, verify the public server profile too.

Monitoring

CPU, RAM, server FPS, uptime and crash monitoring

Server health is more than online/offline. CPU, RAM, disk I/O, server FPS and restart history show whether the host is stable.

DayZ server FPS low DayZ crash log DayZ server monitoring

Low server FPS often points to too much AI, scripts or a problematic mod.
For crash loops, inspect the latest RPT logs.
After restart, verify ports and RCON are reachable again.

Backup

Backups, rollback and safe maintenance

Before major config, modlist or mission changes, keep a restorable backup. Good snapshots separate config, profiles, mission files and keys.

DayZ server backup DayZ rollback DayZ mission backup

Do not restore profile or mission files while the server is running.
Keep ZIP snapshots on a separate drive too.
Clean old crash/log files, but keep recent failures for diagnostics.

Maps and mission

Chernarus, Livonia and custom map mission handling

Changing a map is more than changing one name. Mission path, mod dependencies, economy files and profile data all decide whether the server starts cleanly.

DayZ Chernarus server setup DayZ Livonia mission DayZ custom map server

The serverDZ.cfg template value must match the selected map.
For custom maps, verify required mods and their order.
Before economy or types edits, create a separate mission backup.

Logs and errors

RPT logs, script errors and startup troubleshooting

When a server starts and closes, or players hit join errors, the fastest path is reading the newest RPT and crash files first.

DayZ RPT log error DayZ server crash startup DayZ missing addon

Always inspect the latest startup log first.
For mod problems, look for missing addon, signature or script exception lines.
For config problems, check quotes, semicolons and paths.

FAQ

Common DayZ server questions

Why is my DayZ server not visible in server lists?

The most common causes are ports, query port, firewall rules or a wrong public IP. Verify game/query reachability, server process state and the web profile data.

Why do players get kicked for mod errors?

The client mod list, server mod list or bikey files may be out of sync. Update Workshop content, sync the keys folder and restart the server.

When should I use RCON?

Use RCON for broadcasts, player lists, kick/ban style admin actions and many remote dashboard operations.

What should I back up before DayZ server maintenance?

Back up serverDZ.cfg, profile folder, mission files, keys folder, mod manifest and admin/RCON settings at minimum.

Why does the server start and then close immediately?

Common causes include a broken serverDZ.cfg, wrong mission template, missing mod dependency or incorrect launch path. The newest RPT log usually shows where startup fails.

Why should each server use its own profile folder?

The profile folder stores logs, BattlEye data and runtime files. Sharing it between servers makes errors and state much harder to reason about.
