有没有人一起使用start-stop-daemon和mono-service2?我已经为此战斗了几天,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。成功启动 - 停止守护进程和mono-service2?

以下是我已经学会日期:

  1. 单声道或单服务EXE必须命名为变量DAEMON(你不能列出你的exe作为DAEMON)

  2. 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)。

  3. 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:

我们有很多与单服务问题,并最终在我们的应用程序实现我们自己的“服务”的代码。没什么难,只要抓住一些信号:

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 
    } 
}

我得到这个脚本以微小的改动工作:

  • ,如果你以root身份运行在/ var/A pidfile进程文件,只运行工作 - 如果您尝试在没有sudo的情况下运行脚本,单声道服务将无声无息地失败。

  • 使用--pidfile而不是--name来查找要停止的服务。

我知道这个问题是旧的,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。我的博客上讲述在这里:http://www.geekytidbits.com/start-stop-daemon-with-mono-service2/

虽然这可能会在理论上回答这个问题,但我们希望您在回答中包含链接文章的基本部分,并提供[链接供参考](http://meta.stackexchange.com/q/8259 )。如果做不到这一点,答案就会受到链接腐败的威胁。 – Kev 2012-08-07 23:23:56

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" 

} 

所以它的工作原理,我认为它只是因为你不能用命令停止进程“启动 - 停止守护” 我学习,现在使用单声道,你的邀请非常帮助我,谢谢你。 我的英语很差,原谅我的英文不成熟。
