Server¶

This guide will explain how to setup an AllTheMods server locally, or with a server host.

Prerequisites¶

Server with at-least 8GB+ RAM (As required for most ATM packs).
CPU that’s atleast 3.5Ghz of speed.
Specific Java version based on the pack Minecraft version.

Installation¶

Download modpack Server-Files from CurseForge.
Extract Server-Files to a folder.

If you’ve a 3rd party Anti-Virus installed, exclude the folder the files will be extracted too, as files may get remove or corrupted after extracting.

Java¶

If you have multiple Java versions installed, the default java -version will be used, which may not be the correct version based on the Minecraft version. There’s 3 solutions,

Edit the server script, changing java to correct java binary path.
- Ex: "C:\Program Files\Java\jre-17\bin\java.exe" @user_jvm_args.txt ...
Remove old / add the correct java/bin path to System Environment Variables > Path
Linux, you can re-configure Java using sudo update-alternatives --config java
Uninstall all Java versions except the one being used.

If you’ve installed Java, you may need to restart OS.

Local Installation¶

Extract Server-Files to a folder.
Window: Do not unzip files under OneDrive or any other cloud folder, as this can potentially remove / corrupt files.
Linux: Ensure server folder has read/write permission, and script has execute permission,
- To avoid any read/write permission errors, install server under /home/<user>/ folder.
- Run once: sudo chmod +x startserver.sh.
Starting Server:
- Windows: Execute startserver.bat
- Linux: Execute ./startserver.sh

After running, you’re required to accept Minecraft Eula in the eula.txt file.

Make any changes necessary to server.properties, configs, and or world/serverconfigs, and run startserver.bat/sh again to start the server.

Warning

Many guides tell you to edit server-ip or server-port. In most cases you DO NOT need to edit these, especially server-ip. This can prevent your server from starting.

There’s no startserver.bat/sh script?

Install Forge first,

java -jar forge-installer*.jar --installServer
You will then instead run.bat/sh to start server.

There’s no run.bat/sh?

Expecting this is an older Forge version, you’ll need to create a script that launches Forge.

run.bat/sh

java -Xms4G -Xmx8G -jar forge-*universal.jar

How to allocate RAM or add Arguments?

Allocating RAM and or adding Arguments are applied within usr_jvm_args.txt. Older versions of Forge will require adding arguments in the script file, if that file doesn’t exist.

How To Import A World?

Upload world folder to server folder. Make sure the world folder is named world.

Performance Tips: Check out Lag / Profiling

Server Host Installation¶

Most server host has a one-click server installer you can use, otherwise

If possible, setup a fresh Forge server based on the current Forge version of the pack.
- If host has no Forge installer, read Server Host Custom Jar
Upload extracted Server-Files to host, via FTP or STFP.
- To connect to FTP/SFTP, you could use a client like FileZilla.
- If there’s no FTP/SFTP, you may be able to upload the Server-Files zip, and extract on server host via their online File Manager.

Server Host Custom Jar¶

If server host requires a .jar file, later Forge versions cannot be ran directly. If older, you can upload and use the forge-*universal.jar as custom jar. Extract & Upload Server-Files to main server folder. Otherwise,

Download ServerStarter jar, then upload to main server folder. Use this as the custom jar.
Download pack Server-Files from CurseForge, extract, and upload ALL to main server folder.
Create a file named server-setup-config.yaml, and copy / paste the config example below.

Modifiy config for pack if necessary, specifically the mcVersion and loaderVersion, and place config in server root then start server as normal.

Updating¶

Updating ATM servers is pretty simple. There’s 3 ways you can accomplish this.

BACKUP world before proceeding.

Automatic¶

If you have a server host with a modpack installer, usually you can do a one-click update within your control panel.

Manually (2 methods)¶

Backup any modified configs or kubejs scripts, if any, to be replaced later.
- Download Server Files from CurseForge
- Delete kubejs, defaultconfigs, mods, and config folder.
- If server forge version is different, delete libraries folder, and copy over new startserver.bat/sh, & forge-installer.jar if exists.
- Extract the deleted folders from Server Files into your server folder.
Download Server Files from CurseForge.
- Extract Server Files to a new folder.
- Copy world, local folder, server.properties, & eula.txt to new server folder.
- If journeymap folder exist, copy over aswell.
- Copy over any modified server configs/kubejs scripts
