Rails 3.1 + Heroku = 工人崩溃 [英] Rails 3.1 + Heroku = Workers crashing
本文介绍了Rails 3.1 + Heroku = 工人崩溃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
所以，我刚刚创建了一个全新的 Rails 3.1.1 应用(Ruby 1.8.7).
在那里放几个脚手架，安装 Authlogic，并创建一个新的 Heroku 应用程序.将其推送到 Heroku 并迁移数据库.
一切都很好.我可以使用 Authlogic 创建新用户帐户，并在 Heroku 上的模型中创建新记录.
不过，有趣的事情.如果我将我的 'worker dynos' 从零增加到任何值，heroku 日志会显示那些试图启动但他们崩溃的工人.
但是，我没有安装延迟作业.并且从未在此应用中引入延迟工作
除了 Twilio 或任何高级代码之外，我还没有介绍任何高级" gem.这只是带有 authlogic 的新 Rails 应用程序.也没有新的佣金任务.
另一个注意事项:在我的本地开发机器上，我尝试在不同的应用程序上安装 Delayed Job 并失败了.延迟工作的幽灵"会不会困扰着这款新应用?
谢谢！
下面的代码.....
在我将 Web 工作者从 0 增加到 2 后，Heroku 会记录.

Worker dynos 专门处理延迟工作任务.
如果您没有安装 Delayed Job，那么您不应该扩展您的工作人员数量(这就是 DJ 工作的需要).
如果您想扩展您的网络动态，那么只需扩展 web=2 或任何您想要的.
我猜你的错误是因为你新扩展的 DJ 工作人员找不到任何工作要做，结果出错了.
Scale worker=0，看看是否能解决问题.
如果您想扩展 Web dynos 以获得更好的性能，那么 Web 就是您要寻找的.
有关 Heroku dyno 类型的更多文档，请访问:https://devcenter.heroku.com/articles/scaling
So, I just stood up a brand new Rails 3.1.1 app (Ruby 1.8.7).
Put a few scaffolds in there, installed Authlogic, and created a new Heroku app. Pushed it to Heroku and migrated the DB.
And all is well. I can make new user accounts with Authlogic and make new records in my models on Heroku.
Funny thing, though. If I increase my 'worker dynos' from zero to anything, the heroku logs show those workers trying to start and they crash.
But, I don't have Delayed Job installed. And never introduced Delayed Job to this app
I also haven't introduced any 'advanced' gems other than Twilio or any advanced code. It's just the new rails app with authlogic. No new rake tasks either.
One other note: On my local development machine, I tried to install Delayed Job on a different app a while back and failed. Could the 'ghosts' of delayed job be haunting this new app?
Thanks!

Worker dynos work exclusively on Delayed Job tasks.
If you don't have Delayed Job installed, then you shouldn't be scaling your worker count (which is what takes care of DJ Jobs).
If you mean to scale your web dynos, then simply scale web=2 or whatever you desire.
I'm guessing your error is because your newly scaled DJ workers can't find any jobs to do, and it errors out.
Scale worker=0 and see if that fixes it.
And if you want to scale your web dynos for better performance, web is what you're looking for.
