开始成功

有没有人一起使用start-stop-daemon和mono-service2? 我已经为此奋斗了几天,并且已经获得了各种各样的工作,但是在为单声道服务获取全功能初始化脚本方面没有取得成功。

这是我迄今为止所了解到的:

  • 单声道或单声道服务exe文件必须命名为变量DAEMON(不能将您的exe文件列为DAEMON)

  • 你必须使用--background标志......否则当这个脚本从包安装程序执行时(deb在我的情况下)。 服务在安装程序结束时终止(与安装程序分叉过程如何有关......我没有调查过这么多)。

  • 我已经成功地在其他脚本中列出带有mono-service标志的pid文件并使用它来停止守护进程,但由于某种原因,它在这里不起作用。 正如下面的脚本不会停止服务 - 不知道为什么。 开始工作正常。

  • 这里是我的部分功能初始化脚本:

    我们在单一服务方面遇到了很多问题,并最终在我们的应用中实施了自己的“服务”代码。 没有什么困难,只是抓住一些信号:

    UnixSignal intr = new UnixSignal (Signum.SIGINT);
    UnixSignal term = new UnixSignal (Signum.SIGTERM);
    UnixSignal hup = new UnixSignal (Signum.SIGHUP);
    UnixSignal usr2 = new UnixSignal (Signum.SIGUSR2);
    
    UnixSignal[] signals = new UnixSignal[] { intr, term, hup, usr2 };
    
    for (bool running = true; running; )
    {
        int idx = UnixSignal.WaitAny(signals);
    
        if (idx < 0 || idx >= signals.Length) continue;
    
        log.Debug("daemon: received signal " + signals[idx].Signum.ToString());
    
        if ((intr.IsSet || term.IsSet)) 
        {
            intr.Reset ();
            term.Reset ();
    
            log.Debug("daemon: stopping...");
    
            running = false;
        }
        else if (hup.IsSet)
        {
            // Ignore. Could be used to reload configuration.
            hup.Reset();
        }
        else if (usr2.IsSet)
        {
            usr2.Reset();
            // do something
        }
    }
    

    我知道这个问题很老,但没有被接受的答案。 我对此也进行了一段时间的修改,并提出了一个守护进程脚本,这对我来说就像是一种魅力。 我在这里发表了博客:http://www.geekytidbits.com/start-stop-daemon-with-mono-service2/


    我得到这个脚本与一些小的变化工作:

  • / var / run中的pid文件仅在以root用户身份运行时起作用 - 如果您尝试在不使用sudo的情况下运行脚本,单声道服务将无提示失败。

  • 使用--pidfile而不是--name来查找停止的服务。
