Heroku上的Ruby守护进程 [英] Ruby daemons on Heroku

问题描述

我试图在Heroku上执行ruby daemon framework-less 应用程序，但在尝试执行worker之后崩溃：

  heroku [worker.1]：状态从崩溃转变为开始
 heroku [worker.1]：使用命令`bundle exec rake twitter：start`启动进程
 heroku [worker.1]：状态从开始改为
 heroku [worker.1]：进程退出状态为0 
 heroku [worker.1]：状态从up改为崩溃
  

该应用程序基本上通过一堆API收集数据，并将其保存在远程MongoHQ实例中。

rake任务是：

$ $ $ $ $ $ $ $ dir_path = File.expand_path（'../ '，__FILE__）

命名空间：twitter do
desc'启动Twitter守护进程'
任务：开始执行
exec＃{dir_path} / bin / autana start
结束

...
结束

Procfile非常简单： worker：bundle exec rake twitter：start $ b

执行守护进程的代码如下：



 ＃！/ usr / bin / env ruby​​ 
 require'daemons'
 require File.expand_path（'../../ lib / autana'，__FILE__）
 
 damons.run_proc（'autana'，multiple：true，no_pidfiles：true）做
 client = Autana :: Client :: Twitter.new 
 client.collect 
 end 
  

有什么想法？


解决方案

所以，这是一个MongoDB错误。数据没有正确关联。进入控制台并更改文档后，所有内容均按预期工作。

I'm trying to execute a ruby daemon framework-less app on Heroku, but it crash after trying to execute the worker:

heroku[worker.1]: State changed from crashed to starting
heroku[worker.1]: Starting process with command `bundle exec rake twitter:start`
heroku[worker.1]: State changed from starting to up
heroku[worker.1]: Process exited with status 0
heroku[worker.1]: State changed from up to crashed

The app basically collects data, through a bunch of APIs, and saves it on a remote MongoHQ instance.

The rake tasks are:

dir_path = File.expand_path('../', __FILE__)

namespace :twitter do
  desc 'Start Twitter daemon'
  task :start do
    exec "#{dir_path}/bin/autana start"
  end

  ...
end

The Procfile is very simple: worker: bundle exec rake twitter:start

The code that executes the daemon is the following:

#!/usr/bin/env ruby
require 'daemons'
require File.expand_path('../../lib/autana', __FILE__)

Daemons.run_proc('autana', multiple: true, no_pidfiles: true) do
  client = Autana::Client::Twitter.new
  client.collect
end

Any ideas?

解决方案

So, it was a MongoDB error. Data was not properly associated. After entering the console, and changed the document, everything worked as expected.
