Description

Legacy4Server

A lightweight performance-oriented server-sided modpack for Legacy4J.

Information

Legacy4Server is a fork of the private Re-Console SMP modpack, built for community usage.

This is the general guide for installation.

Download mrpack-install through GitHub releases (or your distro's package if it has one) and take a look at the commands on the README. In Legacy4Server's case, to install in your server you would run:

mrpack-install Legacy4Server [optional version number]

It's a good idea to have some knowledge on using Docker before doing this.

  1. Make sure you have Docker Engine installed properly according to the Docker docs
  2. Create a new directory
  3. Place the contents below in a file called docker-compose.yml. This Compose file also contains some other server tweaks meant for performance, such as disabling sync-chunk-writes, reducing render and simulation distance, and more
  4. Run docker compose up -d in that directory

For any other information, you can read through the Docker Minecraft Server documentation.

mcman is a tool for managing the mods/plugins/configurations of a Minecraft server. First, install mcman from releases. To import Legacy4Server while initializing a server, use this command:

mcman init --mrpack mr:legacy4server

After initializing and importing the mrpack, run mcman build to build the server into the server/ directory, from which you can call cd server && sh start.sh or cd server && call start.bat. For more information, check out mcman's docs.

See the mrpack4server Git repository for installation info. modpack-info.json:
