server-ip defaults to empty (0.0.0.0). Binding to the resolved public IP of reaperofveriod.nl crashed the server with 'Cannot assign requested address', since that IP isn't assigned to a local interface (NAT behind the edge router).

# Reaper's Sky - Dedicated Server
|
|
|
|
Everything needed to run the Reaper's Sky NeoForge **1.21.1** server (NeoForge
|
|
**21.1.248**) on Debian 13 (trixie).
|
|
|
|
## Quick start (on the server box)
|
|
|
|
```sh
|
|
sudo ./deploy.sh # installs Java 21 + curl/unzip, NeoForge, the 59 mods, config
|
|
./run.sh # start the server (run inside tmux/screen so it survives logout)
|
|
```
|
|
|
|
The first `./run.sh` generates the world. Wait for `Done (...)` in the console,
|
|
then connect with IP **`reaperofveriod.nl`** (port 25565).
|
|
|
|
`deploy.sh` is idempotent — safe to re-run; it skips anything already in place
|
|
and verifies every mod by sha1 before installing.
|
|
|
|
## What deploy.sh does
|
|
|
|
| Step | Result |
|
|
|------|--------|
|
|
| System packages | `openjdk-21-jre-headless`, `curl`, `unzip` (needs root/`sudo`) |
|
|
| NeoForge server | Official installer from Maven → server files + `libraries/` |
|
|
| Mods | Downloads the 59 server-safe mods pinned in `mods.json`, sha1-verified |
|
|
| Config | `eula.txt` (EULA accepted), `server.properties` (IP, motd, 8 G) |
|
|
| Run script | `run.sh` with 8 GB + G1GC (`nogui`) |
|
|
|
|
Install location defaults to `~/reaper-sky-server`. Override with `DIR=/path`,
|
|
memory with `MEMORY=6G`, etc.:
|
|
|
|
```sh
|
|
sudo DIR=/srv/minecraft MEMORY=10G ./deploy.sh
|
|
```
|
|
|
|
## Keeping it running
|
|
|
|
```sh
|
|
tmux new -s mc # new session
|
|
cd ~/reaper-sky-server && ./run.sh
|
|
# detach with Ctrl-b d, reattach later with: tmux attach -t mc
|
|
```
|
|
|
|
Stop the server cleanly with the console command `stop` (Ctrl-c also works).
|
|
|
|
## Configuration notes
|
|
|
|
- `server.properties` sets `online-mode=true` (Mojang authentication). Set it to
|
|
`false` in `~/reaper-sky-server/server.properties` to allow unauthenticated
|
|
clients, then restart.
|
|
- `server-ip` is left **empty** on purpose: the server binds all interfaces
|
|
(`0.0.0.0`) and is reached through the edge router's port-forward. Do **not**
|
|
put the public hostname/IP here — it isn't assigned to a local interface and
|
|
the server will crash with `Cannot assign requested address`.
|
|
- `difficulty=hard`, `spawn-protection=0`, `view-distance=10` are set for the
|
|
airship-focused, land-claim-friendly experience.
|
|
- The 19 client-only mods (Iris/shaders, Sodium, Minimap, Jade, JEI, etc.) are
|
|
intentionally excluded here — the server is pure gameplay logic.
|
|
|
|
## Updating the pack
|
|
|
|
1. Add/remove mods in the Prism instance `Reaper's Sky - dev`.
|
|
2. Rebuild + push the mrpack (see repo root `README.md`).
|
|
3. Re-run `server/build_mods.py` or regenerate `mods.json`, commit, push.
|
|
4. On the server: `git pull && sudo ./deploy.sh && ./run.sh`
|
|
(also remove any stale jars from `~/reaper-sky-server/mods/` first). |
