Installer un Serveur Minecraft (Spigot/Paper) sur Ubuntu/Debian

📝 Note: L'installation d'un serveur Spigot/Paper sur Linux est très simple.
A première vus ça semble compliqué quand on voit la taille de la page. J'ai seulement essayé de détailler les étapes au maximum.
Il suffit d'un minimum de connaissance Linux et savoir faire des copier-coller.

Spigot : Permet d'installer des mods mais aussi d'optimiser les performances du serveur
Paper: Un fork de Spigot avec plus d'options, augmente les performances et corrige certains gameplay.
Dynmap : Permet de voir la carte du serveur depuis un navigateur. Exemple: https://mc.sheikah.org
CoreProtect : Permet de faire des retours arrière sur une zone ou voir qui a placé un bloc, cassé, pris un truc dans un coffre, etc…

Dans mes étapes je vais utiliser # ou $ avant chaque commande.
# pour les commandes à utiliser en root (ou sudo)
$ pour les commandes à exécuter en tant qu'utilisateur.

J'ai choisi 'mc' en nom d'utilisateur et 'password1234' en mot de passe.

Je divise l'installation en 4 étapes + 2 Facultatifs:
1. Installation des dépendances
2. Installation de Spigot ou Paper
3. Configuration du serveur
4. Optimisation
5. Installation de dynmap sur une base MySQL et NGINX en serveur WEB (Facultatif)
6. Installation de CoreProtect avec une base MySQL (Facultatif)

1. Installation des dépendances et de Spigot/Paper

4 dépendances à installer :
open-vm-tools > (Facultatif si vous n’utilisez pas une machine virtuelle)
default-jre > nécessaire pour lancer le serveur qui est sur java
git > nécessaire pour compiler Spigot
screen > pour exécuter le serveur en tache de fond.

# apt install open-vm-tools default-jre git screen

2a. Instalation de Spigot (Si vous voulez utiliser paper passez a l'etape 2b)

$ mkdir ~/BuildTools
$ mkdir ~/server
$ cd ~/BuildTools
$ wget https://hub.spigotmc.org/jenkins/job/BuildTools/lastSuccessfulBuild/artifact/target/BuildTools.jar
$ java -jar BuildTools.jar --rev 1.16.2

📝 Note: J'installe la version 1.16.2. Mais vous pouvez installer une autre version.
Voir: https://www.spigotmc.org/wiki/buildtools/#versions

$ cp spigot-1.15.jar ~/server/spigot.jar
$ cd ~/server/
$ echo "eula=true" > eula.txt
$ nano start.sh

Copiez et Collez le contenu en vert et sauvegardez (Ctrl+X)

#!/bin/sh
cd /home/mc/server && screen -d -m -S "mc" java -Xms8G -Xmx8G -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=100 -XX:+DisableExplicitGC -XX:TargetSurvivorRatio=90 -XX:G1NewSizePercent=50 -XX:G1MaxNewSizePercent=80 -XX:G1MixedGCLiveThresholdPercent=35 -XX:+AlwaysPreTouch -XX:+ParallelRefProcEnabled -Dusing.aikars.flags=mcflags.emc.gs -jar spigot.jar nogui

📝 Note: Changez les valeurs -Xms8G -Xmx8G en fonction de la mémoire que vous souhaitez allouer au serveur Minecraft.
Si le serveur a 8GB de mémoire il faut laisser suffisamment de mémoire pour l'OS. Mon serveur a 13GB de mémoire.
Je donne 8GB pour Minecraft, 2.5GB pour la base MySQL de Dynmap/CoreProtect et le reste pour l'OS et NGINX.

2b. Installation de Paper

Téléchargez la dernière version de paper ici: https://papermc.io/downloads

$ mkdir ~/server

Placez la dans ~/server/ puis allez dans le répertoire:

$ cd ~/server

Créez le script de démarrage du serveur:

$ nano start.sh

Copiez et Collez le contenu en vert et sauvegardez (Ctrl+X)

#!/bin/sh
cd /home/mc/server && screen -d -m -S "mc" java -Xms8G -Xmx8G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true -jar paper*.jar nogui

📝 Note: Changez les valeurs -Xms8G -Xmx8G en fonction de la mémoire que vous souhaitez allouer au serveur Minecraft.
Si le serveur a 8GB de mémoire il faut laisser suffisamment de mémoire pour l'OS. Mon serveur a 13GB de mémoire.
Je donne 8GB pour Minecraft, 2.5GB pour la base MySQL de Dynmap/CoreProtect et le reste pour l'OS et NGINX.

Le rendre exécutable:

$ chmod +x start.sh

Acceptez l'eula:

echo "eula=true" > eula.txt

Démarrez le serveur:

$ ./start.sh

Se connecter à la console:

$ screen -r mc

Une fois le serveur démarré tapez stop et Entré pour l'arrêter.

3. Configuration du serveur

Editez le fichier server.properties en fonction de vos préférences.

$ nano ~/server/server.properties

Modifiez ces lignes

enable-query=true
level-name=BroCorp
motd=MC.SHEIKAH.ORG
white-list=true
snooper-enabled=false
difficulty=hard
network-compression-threshold=512

4. Optimisation de Spigot/Paper

Editez le fichier bukkit.yml et changer ces 2 valeurs:

$ nano ~/server/bukkit.yml

query-plugins: false
ambient: 4

query-plugins -> désactive la possibilité de lister les plugins par un api externe
ambient -> nombre de chauves-souris

Editez le fichier spigot.yml avec ces valeurs:

nano ~/server/spigot.yml

world-settings:
  default:
	mob-spawn-range: 4
	arrow-despawn-rate: 600
...
	merge-radius:
		exp: 6.0
		item: 4.0
...
	entity-activation-range:
		animals: 16
		monsters: 24
		raiders: 48
		misc: 8
		tick-inactive-villagers: false
		wake-up-inactive:
		villagers-every: 300
...
	max-tick-time:
		tile: 1000
		entity: 1000

Pourquoi ces valeurs?
https://aikar.co/2015/10/08/spigot-tick-limiter-dont-use-max-tick-time/
https://www.spigotmc.org/wiki/reducing-lag/

Editez le fichier paper.yml avec ces valeurs:

nano ~/server/paper.yml

    allow-headless-pistons: true
    allow-permanent-block-break-exploits: true

# Have dynmap migrate old chunks to the new format for the current MC version (specifically, for migrating pre-1.13 chunks to 1.13 or 1.14). This is needed
# in order to render chunks on an upgraded server (due to various bugs/limitations in CB/spigot 1.13+). This setting is NOT suggested to be enabled full time,
# but only long enough to do a fullrender of a migrated world - it should be turned back off once worlds are migrated). It is EXPERIMENTAL, so be sure to backup
# your worlds before running with this setting enabled (set to true)
