# Reaper's Sky - dedicated server deploy script (Debian 13 / trixie)
|
||||
#
|
||||
# Installs everything needed to run the Reaper's Sky NeoForge 21.1.248 server:
|
||||
# - OpenJDK 21 (JRE, headless) + curl/unzip
|
||||
# - NeoForge 21.1.248 server via its official installer
|
||||
# - the 59 server-safe mods (pinned in mods.json, verified by sha1)
|
||||
# - eula.txt + server.properties (IP reaperofveriod.nl)
|
||||
# - run.sh (8 GB, G1GC)
|
||||
#
|
||||
# Usage: sudo ./deploy.sh (installs packages, needs root/sudo)
|
||||
# ./deploy.sh (idempotent; safe to re-run)
|
||||
#
|
||||
# Defaults:
|
||||
# DIR = "$HOME/reaper-sky-server"
|
||||
# MEMORY = 8G
