# How to Install a StarRupture Server?

How to Install a StarRupture Server? – Step-by-step guide for your Starrupture on NexoraHost.

**Quick answer:** Set up your server step by step – check requirements, install files, configure ports and start the service.

This guide shows you step by step how to set up a StarRupture Dedicated Server – from installation and first world creation to port forwarding.

**Note:** StarRupture is in Early Access. Features and requirements may change with updates.

## Requirements

    - **Operating system:** Windows 10/11 or Windows Server 2019/2022 (64-bit)
- **Processor:** 4 cores (i5/Ryzen 5 or better)
- **RAM:** At least 8 GB, 16 GB recommended
- **Storage:** 30-50 GB free disk space
- **Network:** UDP port 7777 must be open
- **Steam account:** Optional, for SteamCMD installation

## Step 1: Install server files

There are two ways to get the server files:

### Method A: Via Steam (easier)

    - Open your Steam library
- Search for **StarRupture Dedicated Server** (Category: Tools)
- Click Install and wait for the download to complete

### Method B: Via SteamCMD (for headless servers)

Run SteamCMD and enter the following commands (App ID is 3809400):

`steamcmd +force_install_dir C:\StarRuptureDS +login your_steam_login +app_update 3809400 validate +quit`

## Step 2: Start the server

Navigate to the installation folder. Right-click **SRServerWithLog.bat** → Edit. Add in the first line:

`start .\StarRuptureServerEOS.exe -Log -port=7777`
Save and run the BAT file. A console window opens – the server is now running.

## Step 3: Create the first world (Manage Server)

StarRupture has an unusual process: The first world is created from the game client, not on the server itself.

    - Launch StarRupture on your PC
- Click **Manage Server** in the main menu
- Enter your server IP and port (default: 7777)
- Set a server management password
- Optional: Set a player/join password
- Click **New Game** – this creates the world on the server
- Click **Start Game** – the server is now running with this world

## Step 4: Set up port forwarding

StarRupture uses **UDP port 7777** for the game connection and a separate query port.

### Windows Firewall (PowerShell as Administrator)

`New-NetFirewallRule -DisplayName "StarRupture Server" -Direction Inbound -Protocol UDP -LocalPort 7777 -Action Allow`

### Router port forwarding

    - Forward UDP port 7777 to your server's local IP
- Also forward the query port (default: 7778)

## Step 5: Join the server

    - Open StarRupture and go to the main menu
- Click **Join Game**
- Select the **Dedicated Server** tab
- Enter server IP and port (e.g. 123.456.789.0:7777)
- Enter the player password (if set)
- Click Connect/Join

## Step 6: Server configuration (DSSettings.txt)

In the server folder you'll find the file **DSSettings.txt**. Here's the full configuration:

`{
  "SessionName": "MyServer",
  "SaveGameInterval": "300",
  "StartNewGame": "false",
  "LoadSavedGame": "true",
  "SaveGameName": "AutoSave0.sav"
}`

    - **SessionName:** Name of your session and save folder
- **SaveGameInterval:** Autosave interval in seconds (300 = 5 minutes)
- **StartNewGame/LoadSavedGame:** After the first world creation ALWAYS set to false/true – otherwise the world will be overwritten on restart
- **SaveGameName:** The save game to load

## Common problems

    - **Server running but no one can join:** Check if a world is running (Manage Server → Start Game). Check firewall and port forwarding
- **World gone after restart:** Check DSSettings.txt: StartNewGame=false and LoadSavedGame=true must be set
- **Server lags heavily:** Check RAM usage. If over 80%, increase RAM. For large factories choose CPU with high single-core performance
- **Wrong password:** Management password and player password are different. To join you need the player password
