• 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

Om dessa guider

Minecraft Java är den utgåva som flest servrar kör, och den som har riktiga plugins, mods och datapack. Guiderna här täcker en servers hela liv: välja version och servertyp, lägga till plugins eller ett modpack, redigera server.properties, ge dig själv och din personal rätt rättigheter, ladda upp en värld och hålla alltihop snabbt när folk väl börjar spela.

Är du nybörjare, läs guiden om första stegen och versionsguiden innan du installerar något, för servertypen du väljer avgör vad som kommer att gå att läsa in senare och vad som inte gör det. Paper, Purpur, Spigot, Fabric och Forge går inte att byta rakt av, och att hoppa mellan dem efter att du byggt upp en lista med plugins eller mods är den vanligaste röran man kan slippa.

• Gå med i din Minecraft Java-server

  Hur du hittar serverns adress i panelen och lägger till den i Minecraft Java-klienten, och varför rätt klientversion oftast är lösningen när du inte kan ansluta.

• Servern syns inte i serverlistan

  De tre vanliga orsakerna till att en server inte dyker upp i din Minecraft-serverlista, och hur du kontrollerar var och en: servern startar fortfarande, IP eller port är fel, eller din version matchar inte.

• Allowlist och whitelist förklarat

  Vad allowlist (Bedrock) och whitelist (Java) gör, kommandona för att sköta dem, och den klassiska fällan där du slår på listan utan namn och stänger ute alla, inklusive dig själv.

• 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.
