C＃服务作为一个守护进程在debian与单声道服务 [英] C# service as a daemon in debian with mono-service

问题描述

我似乎没有找到一种方法来获得一个C＃服务，作为debian中的服务运行。
我做错了什么？

我从msdn跟随这个帖子来创建一个示例的Windows服务： http://msdn.microsoft.com/en-us/library/zt39148a（v = vs80） .aspx

我可以在我的Windows机器上运行服务，启动并停止服务，看到它写入MyNewLog。

然后我将它（.exe文件）复制到我的debian机器，并尝试使用（作为root用户）单声道服务运行MyNewService.exe

Syslog告诉我服务已经开始了！

我没有错误，我看不到系统中新创建的任何日志文件。我做错了什么？

如果有帮助，这里是代码：
Program.cs

 使用系统; 
使用System.Collections.Generic; 
使用System.Linq; 
使用System.ServiceProcess; 
使用System.Text; 
 
命名空间MyNewService 
 {
 static class Program 
 {
 ///< summary> 
 ///应用程序的主入口点。 
 ///< / summary> 
 static void Main（）
 {
 System.ServiceProcess.ServiceBase [] ServicesToRun; 
 ServicesToRun = new System.ServiceProcess.ServiceBase [] 
 {
 new MyNewService（）
}; 
 System.ServiceProcess.ServiceBase.Run（ServicesToRun）; 
} 
} 
} 
  

Service.cs

  using System; 
使用System.Collections.Generic; 
使用System.ComponentModel; 
使用System.Data; 
使用System.Diagnostics; 
使用System.Linq; 
使用System.ServiceProcess; 
使用System.Text; 
 
命名空间MyNewService 
 {
 public partial class MyNewService：ServiceBase 
 {
 public MyNewService（）
 {
 InitializeComponent（） ; 
 if（！System.Diagnostics.EventLog.SourceExists（MySource））
 {
 System.Diagnostics.EventLog.CreateEventSource（
MySource，MyNewLog）; 
} 
 myEventLog.Source =MySource; 
 myEventLog.Log =MyNewLog; 
} 
 
 protected override void OnStart（string [] args）
 {
 myEventLog.WriteEntry（Service Started：OnStart）; 
} 
 
 protected override void OnStop（）
 {
 myEventLog.WriteEntry（服务暂停：OnStop）; 
} 
} 
}

解决方案

尝试使用System.Diagnostics.EventLog记录其他地方，也许是文本文件或类似文件。

我最近找不到任何东西，但这个 post 表明，在Linux上运行时，EventLog简单地被丢弃;这是有道理的。

编辑：

调查Mono源似乎承担了这一点。事件记录有三种可能的选项：win32，local和null。如果MONO_EVENTLOG_TYPE环境变量设置为本地，那么在Linux上，默认情况下，日志应写入/ var / lib / mono / eventlog。

你真的需要隔离您的记录代码从您的期望 - 似乎您的服务工作正常，但记录是问题。

I can't seem to find a way to get a C# service run as a "service" in debian. What Am I doing wrong?

I followed this post from msdn to create a sample windows service : http://msdn.microsoft.com/en-us/library/zt39148a(v=vs.80).aspx

I can run the service at my windows machine, Start and stop the service and see that it writes to MyNewLog.

Then I copy it (.exe file) to my debian machine and tries to run it with (as root) mono-service MyNewService.exe

The Syslog tell's me that the service have started!

I have no errors and I can't see any newly created logfiles in the system. What Am I doing wrong?

If it helps, here is the code: Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceProcess;
using System.Text;

namespace MyNewService
{
static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    static void Main()
    {
        System.ServiceProcess.ServiceBase[] ServicesToRun;
        ServicesToRun = new System.ServiceProcess.ServiceBase[]
        { 
            new MyNewService() 
        };
        System.ServiceProcess.ServiceBase.Run(ServicesToRun);
    }
}
}

Service.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;

namespace MyNewService
{
public partial class MyNewService : ServiceBase
{
    public MyNewService()
    {
        InitializeComponent();
        if (!System.Diagnostics.EventLog.SourceExists("MySource"))
        {
            System.Diagnostics.EventLog.CreateEventSource(
                "MySource", "MyNewLog");
        }
        myEventLog.Source = "MySource";
        myEventLog.Log = "MyNewLog";
    }

    protected override void OnStart(string[] args)
    {
        myEventLog.WriteEntry("Service Started: OnStart");
    }

    protected override void OnStop()
    {
        myEventLog.WriteEntry("Service Halted: OnStop.");
    }
}
}

/Cheers

解决方案

Try logging somewhere else than with System.Diagnostics.EventLog, perhaps to a text file or similar.

I can't find anything recent, but this post suggests that the EventLog is simply discarded when running on Linux; which would make sense.

EDIT:

Investigating the Mono source seems to bear this out. There are three possible options for event logging: win32, local and null. If the MONO_EVENTLOG_TYPE environment variable is set to local, then on Linux the logs should be written to /var/lib/mono/eventlog by default.

You really need to isolate your logging code from your expectations - it seems that your service works fine, but the logging is the problem.
