How to Set Up a FiveM Server: Step-by-Step Guide

Introduction

FiveM is a modification framework for GTA V that allows you to run custom multiplayer servers. This guide covers the complete FiveM server setup process on your REXE VDS server, including txAdmin configuration and optimization.

Minimum recommended specs for a FiveM server: 4 CPU cores, 8GB RAM, 50GB NVMe SSD.

Prerequisites

A REXE VDS server with Linux (Ubuntu 22.04 recommended)
SSH access to your server
A Cfx.re account and license key
Path Panel firewall rules configured

Step 1: System Preparation

hljs bash

# Update system
sudo apt update && sudo apt upgrade -y

# Install required packages
sudo apt install -y wget git curl xz-utils screen

# Create FiveM user
sudo adduser fivem --disabled-password --gecos ""
sudo su - fivem

Step 2: Download FiveM Server

hljs bash

# Create server directory
mkdir -p ~/fxserver
cd ~/fxserver

# Download latest FiveM server build
wget https://runtime.fivem.net/artifacts/fivem/build_proot_linux/master/latest/fx.tar.xz

# Extract
tar -xf fx.tar.xz
rm fx.tar.xz

Step 3: txAdmin Setup

txAdmin is the built-in web-based management panel for FiveM servers.

hljs bash

# Start the server for first-time txAdmin setup
cd ~/fxserver
./run.sh

After starting, txAdmin will display a PIN code in the console. Open your browser and navigate to:

http://SERVER_IP:40120

Enter the PIN code displayed in the console
Log in with your Cfx.re account
Follow the setup wizard to configure your server
Enter your Cfx.re license key when prompted

Save your txAdmin credentials securely. You'll use them to manage your server through the web interface.

Step 4: Port Configuration

FiveM requires the following ports:

Port	Protocol	Purpose
30120	TCP + UDP	Game server
40120	TCP	txAdmin web panel

Path Panel Rules

Create the following rules in the REXE Path Panel:

hljs yaml

# Game server port
Protocol: UDP
Destination Port: 30120
Filter: Grand Theft Auto (if available)
Comment: "FiveM game port"

# Game server TCP
Protocol: TCP
Destination Port: 30120
Filter: -
Comment: "FiveM TCP port"

# txAdmin panel (restrict to your IP)
Protocol: TCP
Destination Port: 40120
Filter: -
Comment: "txAdmin panel access"

Restrict txAdmin port (40120) to your IP address only. Do not open it globally.

Step 5: Server Configuration

Edit your server.cfg file:

hljs bash

# Server name
sv_hostname "My REXE FiveM Server"

# Max players
sv_maxclients 64

# License key
sv_licenseKey "your_license_key_here"

# Server tags
sets tags "roleplay, custom"

# OneSync (recommended for 32+ players)
set onesync on

Step 6: Running as a Service

Create a systemd service for automatic startup:

hljs bash

sudo nano /etc/systemd/system/fivem.service

hljs ini

[Unit]
Description=FiveM Server
After=network.target

[Service]
Type=simple
User=fivem
WorkingDirectory=/home/fivem/fxserver
ExecStart=/home/fivem/fxserver/run.sh
Restart=on-failure
RestartSec=10

[Install]
WantedBy=multi-user.target

hljs bash

sudo systemctl daemon-reload
sudo systemctl enable fivem
sudo systemctl start fivem

Performance Optimization

Enable OneSync for better performance with many players
Use server-side resource loading where possible
Monitor RAM usage — FiveM can be memory-intensive
Use NVMe SSD for faster resource loading
Regularly update server artifacts

For servers with 64+ players, we recommend at least 8GB RAM and 6 CPU cores.
