Satisfactory server RAM consumption increases significantly with factory size. 12 GB+ RAM is recommended for large factories.

Installation with SteamCMD

SteamCMD Preparation

hljs bash
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install lib32gcc-s1 lib32stdc++6 -y
sudo adduser steam --disabled-login
sudo su - steam
mkdir ~/steamcmd && cd ~/steamcmd
wget https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz
tar -xzf steamcmd_linux.tar.gz

Downloading Satisfactory Server Files

hljs bash
cd ~/steamcmd
./steamcmd.sh +force_install_dir ~/satisfactory +login anonymous +app_update 1690800 validate +quit

Satisfactory Dedicated Server App ID: 1690800. The initial download is approximately 5-8 GB.

Server Configuration

First Launch

Start the server for the first time to generate configuration files:

hljs bash
cd ~/satisfactory
./FactoryServer.sh -unattended

Wait a few seconds and stop with Ctrl+C. This creates the necessary configuration files.

Engine.ini Configuration

hljs bash
nano ~/satisfactory/.config/Epic/FactoryServer/Saved/Config/LinuxServer/Engine.ini
hljs ini
[/Script/OnlineSubsystemUtils.IpNetDriver]
NetServerMaxTickRate=30

[/Script/SocketSubsystemEpic.EpicNetDriver]
MaxClientRate=104857600
MaxInternetClientRate=104857600

Game.ini Configuration

hljs bash
nano ~/satisfactory/.config/Epic/FactoryServer/Saved/Config/LinuxServer/Game.ini
hljs ini
[/Script/Engine.GameSession]
MaxPlayers=8

ServerSettings.ini

hljs bash
nano ~/satisfactory/.config/Epic/FactoryServer/Saved/Config/LinuxServer/ServerSettings.ini
hljs ini
[/Script/FactoryGame.FGServerSubsystem]
mAutoPause=True
mAutoSaveOnDisconnect=True
mAutoLoadSessionName=default_save

Startup Script

hljs bash
nano ~/satisfactory/start.sh
hljs bash
#!/bin/bash
cd ~/satisfactory
./FactoryServer.sh \
  -unattended \
  -Port=7777 \
  -BeaconPort=15000 \
  -ServerQueryPort=15777 \
  -log \

Multiplayer Configuration

First Connection to Server

  1. Go to the Server Manager tab in-game
  2. Enter your server IP: SERVER_IP:15777
  3. The first player to connect is assigned as admin

Setting Admin Password

From the server console:

server.SetAdminPassword STRONG_PASSWORD

Or from the in-game Server Manager:

  1. Go to the Admin tab
  2. Set the admin password
  3. Edit server name and description

Player Limit

Satisfactory supports 4 players by default, but this can be increased:

hljs ini
[/Script/Engine.GameSession]
MaxPlayers=8

More than 8 players may cause performance issues. Consider your server resources.

Save Management

# Delete backups older than 7 days
find $BACKUP_DIR -name "*.tar.gz" -mtime +7 -delete

echo "Backup completed: satisfactory_save_$DATE.tar.gz"
hljs bash
chmod +x ~/backup_satisfactory.sh
crontab -e

Performance Tips

  • NetServerMaxTickRate: 30 is sufficient for most servers. Increase to 60 for lower latency.
  • RAM Management: Large factories consume significant RAM. Monitor server RAM regularly.
  • Disk I/O: Using NVMe SSD significantly reduces save/load times.
  • Auto Pause: Pausing the server when no players are connected saves resources.

Conclusion

Satisfactory dedicated server setup can be completed quickly with SteamCMD. With proper multiplayer configuration, regular save management, and correct port settings, you can enjoy a seamless factory building experience with friends. REXE VDS high-performance infrastructure provides the resources needed for large factories.
