在Linux上手动安装1.19.2 Fabric服务端

不同服务端的区别参考Wiki

你也可以使用Docker快速安装：https://github.com/itzg/docker-minecraft-server

安装Java

1.18+需要Java17环境，安装步骤参考这篇文章

注意：CPU的指令集不同，需要下载的JDK也不同，可以使用如下命令查看

各配置属性参考Wiki，常用的属性有：

  • online-mode=true 关闭正版验证

  • server-port=xxxxx 运行端口，玩家不需要在URL中输入默认的25565端口

  • white-list=true 启用白名单(如果不想让陌生人进入)，whitelist.json和ops.json在成功启动Server后才会生成

    ops.json自动视为白名单，其格式为

    1
    2
    3
    4
    5
    6
    {
        "uuid":"xxxx"
        "name":"xxxx"
        "level":4
        "bypassesPlayerLimit": false
    }

    whitelist.json格式类似

  • motd：服务器介绍

  • 服务器图标：服务器图标必须为64x64，这里有一个好用的图标制作网站，下载后将图标重命名为server-icon.png，放在根目录

OP在游戏中使用/reload命令可以热加载server.properties中的某些属性，而不需要重启Server

存档自动备份

参考文章

在服务器运行时直接对/world文件夹备份是不安全的，因为此时存档可能是残缺的

应该用命令/save-off停止自动存档，/save-all手动保存所有内容，备份存档后再/save-on开启自动存档
