Question

我正在使用延迟工作来执行后台工作。我正在使用命令RAILS_ENV=production bin/delayed_job -n 5 start

运行延迟的作业

当我开始延迟工作并检查延迟的工作时，它表明工作正在运行。当我在1小时后再次检查延迟的工作时，所有工作的延迟工作状态仍在“运行”。所有工作都应在15分钟内完成，但即使在1小时后，它仍显示运行状态。请帮忙。

以下是我的延迟作业日志文件内容。

I, [2015-12-22T13:10:56.463154 #15255]  INFO -- : 2015-12-22T13:10:56+0000: [Worker(delayed_job.0 host:ip-172-31-6-58 pid:15255)] Job QrCodeGenerator (id=16) RUNNING

正在运行的作业的状态如下所示。

 => #<Delayed::Backend::ActiveRecord::Job id: 15, priority: 0, attempts: 0, handler: "--- !ruby/struct:QrCodeGenerator\nclient: !ruby/obj...", last_error: nil, run_at: "2015-12-22 11:57:28", locked_at: "2015-12-22 13:10:56", failed_at: nil, locked_by: "delayed_job.2 host:ip-172-31-6-58 pid:15267", queue: nil, created_at: "2015-12-22 09:07:39", updated_at: "2015-12-22 11:57:51">

我在延迟工作中插入工作的代码如下。

QrCodeGenerator = Struct.new(:client,:request,:quantity) do
  def perform
      AuthenticationCode.save_qr_codes(client,request,quantity)
  end

  def error(job, exception)
    if request.status != "completed"
      request.update_attributes(:status => "failed")
    end
  end

  def destroy_failed_jobs?
    true
  end

  def max_attempts
    1
  end

end

我想你已经在其他地方入队（并开始）这份工作。因此问题就在于工作继续运行的原因。

我认为您应首先确保流程确实已启动/启动。

然后，gem delayed_job_web 一个有用的界面 来监控进程的状态。

另一方面，您可以尝试设置max_run_time以查看delayed_job是否按预期运行。

# config/initializers/delayed_job_config.rb
Delayed::Worker.max_run_time = 5.minutes
