• Give staff the right tools on a Minecraft server

  A staff team needs enough power to deal with trouble and no more than that. Here is how to split ranks, which commands each tier actually needs, how to log what staff do, and how to remove someone's access cleanly when they leave.

• Enable command blocks and run functions on a server

  Command blocks are off by default on a multiplayer server. Here is how to turn them on, which permission levels decide what they can do, when a datapack function is the better tool, and how both of them cost you performance.

• Change your Minecraft server port

  Your Minecraft port is an allocation on the machine, not just a line in a config file, so you change it on the Ports and network page rather than in server.properties. Here is how, and why you cannot simply pick any number.

• Upgrade a Minecraft world to a new version safely

  Moving a world to a newer Minecraft version converts it permanently, so the order of operations matters. Back up, check your plugins and mods, test on a copy, and know where the new terrain will leave a seam.

À propos de ces guides

Minecraft Java est l'édition que font tourner la plupart des serveurs, et la seule avec de vrais plugins, mods et datapacks. Ces guides couvrent toute la vie d'un serveur : choisir une version et un type de serveur, ajouter des plugins ou un modpack, modifier server.properties, te donner les bonnes permissions et en donner à ton équipe, envoyer un monde, et garder le tout rapide une fois que les gens y jouent vraiment.

Si tu débutes, lis le guide des premiers pas et le guide des versions avant d'installer quoi que ce soit, parce que le type de serveur que tu choisis décide de ce qui se chargera ou non par la suite. Paper, Purpur, Spigot, Fabric et Forge ne sont pas interchangeables, et passer de l'un à l'autre après avoir constitué une liste de plugins ou de mods est le gâchis évitable le plus courant.

• Rejoindre ton serveur Minecraft Java

  Comment trouver l'adresse de ton serveur dans le panel et l'ajouter dans le client Minecraft Java, et pourquoi faire correspondre la version de ton client est presque toujours la solution quand tu n'arrives pas à te connecter.

• Serveur absent de la liste des serveurs

  Les trois raisons habituelles pour lesquelles un serveur n'apparaît pas dans ta liste de serveurs Minecraft, et comment vérifier chacune : le serveur démarre encore, l'IP ou le port est faux, ou ta version ne correspond pas.

• L'allowlist et la whitelist expliquées

  Ce que font l'allowlist (Bedrock) et la whitelist (Java), les commandes pour les gérer, et le piège classique où l'activer sans aucun nom bloque tout le monde, toi compris.

• Converting a Java world to Bedrock

  You can convert a Minecraft Java world to Bedrock using third party tools like Chunker, but it is lossy: terrain and builds usually survive, while entities and container contents often do not, and modded content will not convert at all. Here is the honest process.

• Fix "Address already in use" on a game server

  Two things want the same port and only one can have it. The usual causes are an old process that has not finished dying and a plugin quietly claiming a port of its own.

• Chunk loading, pre-generation and why exploring lags

  Generating new terrain is the heaviest single job your server ever does, which is why a fresh world lags while players explore and then settles down: pre-generating the map ahead of time and capping it with a world border removes the problem for good.
