我有一台运行 Raspberry Pi OS 的 Raspberry Pi 5 8gb，我遇到的问题是qbittorrent-nox，我使用 apt 安装的它在大约 1 分 30 秒后不断崩溃。
因为我有一个自动启动的服务qbittorrent-nox，它会在 3 秒内重新启动，但重新启动很烦人，而且显然不利于播种和吸血，我想知道为什么会发生这种情况。
经过一些实验，日志中有些内容表明服务systemd正在超时，果然，我让用户对 qbit 进行 su-ing 运行，qbittorrent-nox似乎运行良好，无需重新启动。
日志和systemd服务文件之前已经包含过了，我使用了样板代码，没有做太多调整，也不太理解其中的内容。

答案1
服务保持“激活”状态，直到 systemd 收到某种就绪指示（即，服务需要指示它已加载其配置、打开其套接字等）。
告诉Type=forkingsystemd 期望程序将“守护进程化”或“分叉到后台”；这将被视为服务已准备就绪的迹象。但由于 qbittorrent-nox 不会这样做，因此服务将永远处于“激活”状态，直到超时。
添加--daemon选项（首选），或更改Type=forking为Type=simple。
