BattlEye Configuration

BattlEye anti-cheat is enabled by default. You can customize RCON settings in BattlEye/BEServer_x64.cfg:

RConPort 5678
RConPassword myNewBEPassword

⚠️ Warning

Only append new settings to BEServer_x64.cfg. Do not modify existing values or players will receive "Missing GameID/MasterPort server config settings" errors.

Startup Parameters

-config "path/to/config.json"

Server configuration file path. Example:

ArmaReforgerServer.exe -config "./Configs/Campaign.json"
-maxFPS 60Important

Heavily recommended! Limits server FPS to prevent using all available resources. Set to 60-120 range.

ArmaReforgerServer.exe -maxFPS 60
-profile "path/to/profile"

Server profile directory for logs and data.

-listScenarios

Log available scenario .conf file paths on startup.

-server "path/to/world.ent"

Launch server with specific world. Ignores config file. Can combine with -addons and -addonsDir for testing local mods.

ArmaReforgerServer.exe -server "worlds/MP/MPTest.ent" -addonsDir "C:\MyMods" -addons MyMod

SteamCMD Setup

Install the dedicated server using SteamCMD:

1. Install SteamCMD

Download from Valve Developer Wiki

2. Create Install Script

Create update_armar_ds.txt:

@ShutdownOnFailedCommand 1
@NoPromptForPassword 1
force_install_dir ../armar_ds
login anonymous
app_update 1874900 validate
quit
3. Run Installation
steamcmd +runscript update_armar_ds.txt
4. Start Server
./ArmaReforgerServer -config ./config.json -maxFPS 60

Linux Server Setup

Complete Bash Script Setup

Create these files in your server directory (e.g., /home/username/armaR/):

steamShell.txt:

@ShutdownOnFailedCommand 1
login anonymous
app_update 1874900 validate
quit

steamInstall.sh:

#!/bin/bash
/usr/games/steamcmd +force_install_dir /home/username/armaR +runscript /home/username/armaR/steamShell.txt

start.sh:

#!/bin/bash
./steamInstall.sh
./ArmaReforgerServer -config /home/username/.config/ArmaReforgerServer/config.json -profile /home/username/.config/ArmaReforgerServer -maxFPS 60

Docker Setup

A community Docker image is available: github.com/acemod/docker-reforger

Manual Docker Setup (Ubuntu):

# Pull Ubuntu image
docker pull ubuntu:18.04

# Run container with port and volume
docker container run -t -d \
  -p 2001:2001/udp \
  -v /path/to/server:/home/server \
  --name arma_reforger ubuntu:18.04

# Connect to container
docker exec -it arma_reforger /bin/bash

# Install dependencies
apt-get update
apt-get install libcurl4 net-tools libssl1.1

# Run server
./ArmaReforgerServer -config ./config.json -maxFPS 60

💡 Tip

If you get curl errors downloading mods, set -addonTempDir ./tmp to a location with write permissions.
