start-stop-daemon 和 mono-service2 成功了吗? [英] Success with start-stop-daemon and mono-service2?
问题描述
有没有人一起使用 start-stop-daemon 和 mono-service2 成功?我已经为此奋斗了几天,并且已经得到了各种各样的工作,但没有成功地为单声道服务获得功能齐全的初始化脚本.
Has anyone had any success using start-stop-daemon and mono-service2 together? I've been fighting this for a few days now and have gotten various bits to work, but have had no success in getting a fully functional init script for a mono service.
这是我迄今为止所学到的:
Here is what I have learned to date:
mono 或 mono-service exe 必须命名为变量 DAEMON(不能将您的 exe 列为 DAEMON)
The mono or mono-service exe must be named as the variable DAEMON (you can't list your exe as the DAEMON)
您必须使用 --background 标志...否则当从包安装程序(在我的情况下为 deb)执行此脚本时.安装程序结束时服务终止(与安装程序如何分叉进程有关......我没有调查过这么多).
You must use the --background flag ... otherwise when this script is executed from a package installer (deb in my case). The service terminiates when the installer ends (has something to do with how the installer forks processes ... I havent investigated this much).
我已经成功地在其他脚本中列出了带有 mono-service 标志的 pid 文件并使用它来停止守护程序,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.
I have had success with listing the pid file with the mono-service flag in other scripts and using it to stop the daemon, but for some reason it doesnt work here. As such the script below does not stop the service - not sure why. Start works fine.
这是我的部分功能初始化脚本:
And here is my partially functional init script:

推荐答案
我们在使用单服务时遇到了很多问题,最终在我们的应用程序中实现了我们自己的服务"代码.没什么难的,只是抓住一些信号:
We had a lot of issues with mono-service and ended up implementing our own "service" code in our app. Nothing hard, just grabbing some signals:
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
}
}
