Rails 3.1 + Heroku =工人崩溃

时间：2012-04-01 12:15:19

标签： ruby-on-rails ruby-on-rails-3 heroku

所以，我刚刚提出了一个全新的Rails 3.1.1应用程序（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。将它推送到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。

但有趣的是。如果我将'工作人员dynos'从零增加到任何东西，heroku日志会显示那些试图启动并且崩溃的工人。

但是，我没有安装延迟作业。并且从未将延迟工作引入此应用

我还没有介绍除Twilio或任何高级代码之外的任何“高级”宝石。它只是具有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延迟作业，但是失败了。延迟工作的“幽灵”难道会困扰这个新应用吗？

谢谢！

下面的代码.....

我将Web worker从0增加后的Heroku日志 - > 2。

1 个答案:

答案 0 :(得分：4)

工作人员dynos专门处理延迟工作任务。

如果您没有安装延迟作业，那么您不应该扩展您的工作人员数量（这是照顾DJ工作的地方）。

如果您的意思是扩展您的网络动态，那么只需缩放web = 2或任何您想要的。

我猜测你的错误是因为你刚接触过的DJ工作人员找不到任何工作要做，而且错误了。

缩放worker = 0并查看是否修复了它。

如果您想扩展网络动态以获得更好的性能，那么网络就是您所需要的。
