Topshelf在第三次尝试后停止服务恢复

topshelf windows-services c#

我正在使用Topshelf创建一个Windows服务。此服务将尝试恢复前3个故障,但在那之后,它不再工作。

在主机上的服务中检查服务显示:

First Failure:          Restart the Service
Second Failure:         Restart the Service
Subsequent Failures:    Restart the Service
Reset fail count after: 1 days
Restart service after:  2 minutes

服务恢复代码如下所示:

f.EnableServiceRecovery(r =>
{
    r.RestartService(2);
    r.RestartService(5);
    r.RestartService(5);
    r.OnCrashOnly();
    r.SetResetPeriod(1);
});

在恢复失败后,检查事件日志会显示以下消息:

The MyService service terminated unexpectedly.  It has done this 1 time(s).  The following corrective action will be taken in 120000 milliseconds: Restart the service.
The MyService service terminated unexpectedly.  It has done this 2 time(s).  The following corrective action will be taken in 300000 milliseconds: Restart the service.
The MyService service terminated unexpectedly.  It has done this 3 time(s).  The following corrective action will be taken in 300000 milliseconds: Restart the service.
The MyService service terminated unexpectedly.  It has done this 4 time(s).

从上面可以明显看出。第四次不会触发恢复。

这是Windows错误、Topshelf问题还是我的配置有问题?

必须为topshelf恢复设置设置底部配置:

x.EnableServiceRecovery(rc =>
                {
                    // Has no corresponding setting in the Recovery dialogue.
                    // OnCrashOnly means the service will not restart if the application returns
                    // a non-zero exit code.  By convention, an exit code of zero means âsuccessâ.
                    rc.OnCrashOnly();
                    // Corresponds to âFirst failure: Restart the Serviceâ
                    // Note: 0 minutes delay means restart immediately
                    rc.RestartService(delayInMinutes: 0); 
                    // Corresponds to âSecond failure: Restart the Serviceâ
                    // Note: TopShelf will configure a 1 minute delay before this restart, but the
                    // Recovery dialogue only shows the first restart delay (0 minutes)
                    rc.RestartService(delayInMinutes: 1); 
                    // Corresponds to âSubsequent failures: Restart the Serviceâ
                    rc.RestartService(delayInMinutes: 5);
                    // Corresponds to âReset fail count after: 1 daysâ
                    rc.SetResetPeriod(days: 1); 
                });
