Mods are what turn a vanilla DayZ server into a trader economy, a base-building sandbox, or a hardcore PvE world. Unlike many games, DayZ servers don’t pull mods from the Workshop automatically — you install them manually. This guide covers the full process: download, upload, keys, and the -mod<\/code> launch parameter.<\/p>\n

Step 1: Get the mod files<\/h2>\n

Subscribe to the mods you want on the DayZ Steam Workshop<\/a>, then launch DayZ once so Steam downloads them. On Windows you’ll find each mod as an @ModName<\/code> folder under:<\/p>\n

C:\\Program Files (x86)\\Steam\\steamapps\\common\\DayZ\\!Workshop<\/code><\/pre>\n
On a Linux server you can pull them directly with SteamCMD:<\/p>\n
workshop_download_item 221100 <mod_id><\/code><\/pre>\n
Step 2: Upload the @ mod folders<\/h2>\n
Copy each @ModName<\/code> folder into your server root<\/strong> (the same directory as DayZServer_x64.exe<\/code> or the Linux server binary). Folder names are case-sensitive and must keep the leading @<\/code>.<\/p>\n
Step 3: Copy the .bikey files into \/keys<\/h2>\n
This is the step people miss. Inside every mod is a keys<\/code> (or Keys<\/code>) folder containing a .bikey<\/code> file. Copy every one of those into the server’s own keys<\/code> folder:<\/p>\n
\/keys\/CF.bikey\n\/keys\/VPPAdminTools.bikey\n...<\/code><\/pre>\n
If a key is missing, the server’s signature check (verifySignatures = 2<\/code>) will reject any player using that mod with a “you were kicked off the game” error.<\/p>\n
Step 4: Add the -mod launch parameter<\/h2>\n
List every mod in the -mod=<\/code> parameter, separated by semicolons, in load order. Dependencies (like Community Framework, @CF<\/code>) go first:<\/p>\n
-mod=@CF;@VPPAdminTools;@BaseBuildingPlus;@Trader<\/code><\/pre>\n
A typical full Windows launch line looks like:<\/p>\n
DayZServer_x64.exe -config=serverDZ.cfg -port=2302 -cpuCount=4 -dologs -adminlog -netlog -freezecheck -mod=@CF;@VPPAdminTools<\/code><\/pre>\n
Step 5: Restart and verify<\/h2>\n
Restart the server and check the startup log — each mod should load without a “key not found” or “missing dependency” warning. Remember: every player must run the exact same mods in the same versions<\/strong>, and because the server never auto-updates Workshop content, you must re-upload a mod whenever its author pushes an update.<\/p>\n
