start-stop-daemon和mono-service2的成功?

标签: mono daemon init mono-service

有没有人使用start-stop-daemon和mono-service2一起成功?我已经打了好几天了,已经有了不同的工作,但是没有成功为单声道服务获得一个功能齐全的初始化脚本。

这是我迄今所学到的:

  1. 单声道或单声道服务exe必须命名为变量DAEMON(您不能将您的exe列为DAEMON)

  2. 您必须使用--background标志...否则当从包安装程序执行此脚本时(在我的情况下为deb)。安装程序结束时服务终止(与安装程序分叉处理的方式有关...我没有对此进行过多次调查)。

  3. 我已成功将pid文件与mono-service标志列在其他脚本中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。因此,下面的脚本不会停止服务 - 不知道为什么。开始工作正常。

  4. 这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,最终在我们的应用程序中实现了自己的“服务”代码。没什么难的,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
    }
}

我知道这个问题已经过时但是没有接受的答案。我也对此进行了一段时间的修改,并提出了一个守护程序脚本,它对我来说就像一个魅力。我在这里写了博客:http://www.geekytidbits.com/start-stop-daemon-with-mono-service2/

答案 2 :(得分:1)

我让这个脚本处理了一些小的改动:

  • / var / run中的pidfile只有在以root身份运行时才有效 - 如果您尝试在没有sudo的情况下运行脚本,则mono-service将无提示失败。

  • 使用--pidfile而不是--name来查找要停止的服务。

答案 3 :(得分:1)

do_stop()
{ 

test -f $PIDFILE && kill `cat $PIDFILE` && return 2

 start-stop-daemon --stop --quiet --verbose --oknodo --retry=0/30/KILL/5\ 

--exec mono-service2

 [ "$?" = 2 ] && return 2

 # Many daemons don't delete their pidfiles when they exit.

 rm -f $PIDFILE

 return "$RETVAL"

}

所以它有效,我认为这只是因为你无法通过命令“start-stop-daemon”停止进程 我现在正在学习使用单声道,你的邀请对我很有帮助。谢谢你。 我的英语很差,原谅我半生不熟的英语。
