5️⃣ Configuring and starting the server#

🔹 Configuring the startup command#

After installing a modpack, you need to configure the startup command so the server knows which file to execute.

1. Go to the Startup tab
2. Locate the Startup Command section

🔹 Using automatic suggestions#

LibraHost offers an automatic detection feature that analyzes your server files and suggests the appropriate startup command.

1. Click the ✨ (star) button next to the startup command
2. The system automatically analyzes the server files
3. A window opens with startup command suggestions

1. Review the proposed suggestions:
   • Each suggestion displays a name, a description, and a command preview
   • Suggestions are based on detected JAR files (Forge, Fabric, etc.)

1. Click on the suggestion that matches your modpack
2. The command appears in the edit field
3. Click the ✓ (validate) button to save

💡 Tip: If no suggestions appear, verify that the modpack files have been installed at the server root.

🔹 Verifying the Java version#

Make sure the correct Java version is selected:

🔹 Accepting the EULA#

If this is the first installation:

1. Go to the Files tab
2. Open the eula.txt file
3. Change eula=false to eula=true
4. Save the file

🔹 Starting the server#

1. Return to the Console
2. Click Start
3. Wait while the mods load

⏱️ Note: The first startup may take several minutes as the server needs to load all mods and generate configuration files.

The server is ready when you see:

Done (XXs)! For help, type "help"

6️⃣ Connecting to the server#

3. Click Add Server
4. Enter your LibraHost server address
5. Connect and have fun!

🔧 Troubleshooting#

The modpack won't install#

• Check your connection: Installation requires downloading from CurseForge
• Disk space: Make sure you have enough space on your server
• Try again: In case of network error, restart the installation

The server won't start after installation#

• Insufficient RAM: Modpacks often require 4-8 GB of RAM minimum
• Wrong Java version: Check Java/Minecraft compatibility
• Check the logs: The console displays startup errors

"Mod missing" error when connecting#

• Different versions: Make sure you have exactly the same modpack version
• Client-only mods: Some mods are server-side only

The server is lagging or crashing#

• Increase RAM: Via your LibraHost client area
• Reduce render distance: In server.properties, lower view-distance
• Pre-generate the world: Use a mod like Chunky to pre-generate chunks
