Bonjour,
J’ai monté un serveur Minecraft Linux (Ubuntu) sur un Raspberry Pi3
Le serveur lançé manuellement tout fonctionne
Pour aller plus loin j’ai voulu faire en sorte que mon serveur Minecraft démarre automatiquement si le Raspberry démarre.
Voici le script qui est en fait un service que je met dans /etc/rc.local et que je nomme "minecraft"

puis lancé la commande:

Pour moi le service est considéré comme démarré
-Par contre je n'arrive pas à comprendre pourquoi le serveur Minecraft ne se lance pas au démarrage de Raspbian alors que le service est démarré, et pourquoi le serveur démarre correctement si je lance la commande suivante manuellement:
/etc/init.d/minecarft start
Merci à tous pour votre aide
Minecraft ne se lance pas automatiquement au démarrage du Raspberry Pi3
