活动：活动（已退出） plexconnect 服务启动已退出

2024-6-4 • tag-icon

我安装了一个名为“plexconnect”的 Python 脚本，它基本上是一个用来欺骗我的 Apple TV3 在其他地方寻找预告片的脚本。来源：https://github.com/iBaa/PlexConnect

然后我制作了一个初始化脚本。来源：https://forums.plex.tv/discussion/156534/install-on-ubuntu-server

我在使用该守护进程时遇到的（小）问题是，重新启动后，该服务始终以活动状态（退出）启动：

● plexconnect.service - LSB: This is the Plex Connect daemon
   Loaded: loaded (/etc/init.d/plexconnect; bad; vendor preset: enabled)
   Active: active (exited) since sø. 2016-03-27 14:29:27 CEST; 1min 14s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 1043 ExecStart=/etc/init.d/plexconnect start (code=exited, status=0/SUCCESS)
    Tasks: 0 (limit: 512)

mars 27 14:29:27 lenox2 systemd[1]: Started LSB: This is the Plex Connect daemon.

我重新启动服务后，它可以正常工作（正在运行）：

● plexconnect.service - LSB: This is the Plex Connect daemon

我尝试停止 plexmediaserver 并重新启动 plexconnect 以查看是否存在依赖关系问题，但它在没有 plexmediaserver 的情况下运行良好。我还尝试将 plexmediaserver 作为必需启动添加到 init 脚本：

#Required-Start:  networking plexmediaserver

然后：

sudo update-rc.d plexconnect defaults
insserv: Service plexmediaserver has to be enabled to start service plexconnect
insserv: exiting now!

很明显，我在这里陷入了困境，需要帮助。我现在唯一的线索是重启后底部服务状态中的额外 python 行。可能是因为 python 需要成为必需启动？

编辑：

我一直在研究将 sysvinit（plexconnect）转换为 Upstart.conf，因为 plexconnect 是一个 Upstart.conf，但后来我发现 ubuntu 现在使用 systemd。

我现在遇到的问题是，由于某种原因，plexmediaserver 作为 Upstart 运行，当我尝试制作 Upstart plexconnect.conf 时发生了以下情况：

initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

所以现在我更加困惑了...如果 16.04 不允许我更新 Upstart，plexmediaplayer 如何成为 Upstart 服务？（通过 Ubuntu 包安装）。

答案1

主要问题是 Plexmediaserver 使用 Upstart/systemD，因此初始化脚本失败。
