2. Downloading and Installing FiveM Server Files

A. Download the FiveM Server Files

  1. Visit the official FiveM website: https://fivem.net
  2. Download the latest FiveM server build from https://runtime.fivem.net/artifacts/fivem/build_server_windows/master/

B. Get a FiveM Server License Key

  1. Go to the FiveM Keymaster website
  2. Log in and create a new server key
  3. Copy the key—you will need it later for the server.cfg

💡 Tip: Your key must match your server’s IP address.

3. Configuring the FiveM Server

A. Creating the server.cfg File

  1. Inside your FiveM server folder, create a new file named server.cfg
  2. Add the following essential configurations:
cfg
CopyEdit
# Server Name
sv_hostname "My FiveM Roleplay Server"

# License Key
sv_licenseKey "YOUR_SERVER_LICENSE_KEY"

# Max Players
sv_maxclients 32

# Server Tags
sets tags "roleplay,custom,scripts"

# Enable OneSync for better entity synchronization
set onesync_enabled true

# Prevent unauthorized server access
sv_scriptHookAllowed 0

# Network Performance Tweaks
set sv_enforceGameBuild 2802
set sv_maxrate 500000
set sv_minrate 100000
set sv_maxClients 64

B. Starting the FiveM Server

  1. Open Command Prompt (cmd)
  2. Navigate to your server directory:
    sh
    CopyEdit
    cd C:\FiveMServer
  3. Start the server by running:
    sh
    CopyEdit
    FXServer.exe +exec server.cfg
  4. The server console should show "Server running on port 30120"

💡 Tip: Open port 30120 in your firewall settings to allow player connections.

4. Installing Essential FiveM Resources & Mods

To enhance gameplay, install the following core resources:

A. Essential FiveM Frameworks

1️⃣ ESX Framework – Ideal for roleplay servers

sh
CopyEdit
git clone https://github.com/esx-framework/es_extended.git resources/es_extended

2️⃣ QBCore Framework – Lightweight and optimized alternative

sh
CopyEdit
git clone https://github.com/qbcore-framework/qb-core.git resources/qb-core

B. Installing Vehicle & Map Mods

  1. Download custom vehicles from GTA5-Mods.com
  2. Place .ytd and .yft files in the resources folder
  3. Add to server.cfg:
    cfg
    CopyEdit
    start mycustomcar

C. Installing an Anti-Cheat System

To prevent hacking, install EasyAdmin or FiveGuard:

sh
CopyEdit
git clone https://github.com/bluethefurry/EasyAdmin.git resources/EasyAdmin

Add to server.cfg:

cfg
CopyEdit
start EasyAdmin

💡 Tip: Regularly update your FiveM mods and scripts to avoid compatibility issues.

5. Optimizing FiveM Server Performance

A. Monitoring Server Performance

To check resource usage, type in the FiveM console:

sh
CopyEdit
resmon 1
  • Scripts using above 0.20ms per tick should be optimized or removed.

B. Reducing CPU Usage

  1. Limit high-poly custom vehicles
  2. Remove unused scripts from the resources folder
  3. Enable Garbage Collection in server.cfg:
    cfg
    CopyEdit
    set sv_maxClients 64
gc_enable true

C. Restarting the Server Regularly

To prevent memory leaks, create a restart script:

For Windows:

bat
CopyEdit
:start
FXServer.exe +exec server.cfg
timeout /t 21600
taskkill /f /im FXServer.exe
goto start

For Linux:

sh
CopyEdit
#!/bin/bash
while true; do
  ./FXServer +exec server.cfg
  sleep 21600
done

💡 Tip: Restart your server every 6-12 hours to keep performance optimal.

6. Enabling DDoS Protection & Security

A. Using a Firewall to Block Unwanted Traffic

Run this command to block unauthorized connections:

sh
CopyEdit
netsh advfirewall firewall add rule name="FiveM Protection" dir=in action=block protocol=TCP localport=30120

B. Setting Up a Server Password (For Private Servers)

Modify server.cfg:

cfg
CopyEdit
sv_password "MySecretPassword"

C. Using a VPN or Proxy to Hide IP Address

  • If your server is getting DDoS attacks, consider Cloudflare Spectrum or a DDoS-protected VPS.

💡 Tip: Always use a reputable hosting provider that includes DDoS protection.
