先上图

请忽略一下后面凌乱的线，树莓派4B+绿联两盘位硬盘盒，这就是我家的第一台NAS。
树莓派4B的USB3.0升级和自带千兆网卡让NAS成为可能，加上老外玩树莓派的非常多，像N1盒子国内玩的多，自然网上有非常多支持的脚本和镜像，开源软件和社区，这些都是优点。
我的树莓派先安装官方镜像，然后OMV5当NAS管理系统，安装了emby server，安装可道云，docker上安装qbittorrent，安装transmission，安装homeassistant。网上都能找到教程，我只是搬运工，贴上在网上搜集配置的核心命令。毕竟PT也是分享在先，需求在后。
必备1.刷好官方镜像的树莓派.2特殊上网环境（不然换需换源）3.电脑和ssh软件（putty）
