ruby-on-rails - Heroku - 错误 H10(应用程序崩溃)Ruby on Rails

Question

不知道我做错了什么。应用程序在本地运行良好，但我不断收到应用程序错误页面和 H10 error 。我将发布 Rails 控制台输出，因为我读到它比 Heroku 日志更有用，但如果需要，我可以将其放在这里。我真的希望这不会被忽视，因为我现在完全迷失了。

Rails 控制台:

Answer 1

Rails Assets 管道

这可能需要几次迭代才能完成。 Heroku 标记的第一个错误是/favicon.ico 上的 GET 失败

2015-07-05T17:56:19.804219+00:00 heroku[router]: at=error code=H10 desc="App cra
shed" method=GET path="/favicon.ico" host=glacial-falls-7476.herokuapp.com reque
st_id=091b3b97-bbab-4d13-b6a1-da24aa2b018b fwd="50.163.200.7" dyno= connect= ser
vice= status=503 bytes=

这告诉我们存在 Assets 管道问题，因为应用程序应该查找类似下面的文件名的内容，而不是原始文件名:

href="/assets/favicon-17897c732521afcc30d49410042fc687.ico"

favicon 文件名应该是编译后的资源名称。有许多步骤可以对此进行调试:

1. 您在部署之前是否执行了生产 rake？

$bundle exec rake assets:precompile RAILS_ENV=production

非常好，下一步是将应用推送到 Heroku，以部署应用 blob，其中包含为 Rails Assets 管道正确编译的 Assets 。

$heroku push

如果您的应用程序崩溃，请发布更新的 Heroku 日志。如果它运行了，哇哦。这是唯一的问题。

所以简单的解决方案不起作用。它甚至没有编译 .ico 资源。这意味着配置中存在一些问题，因此它无法正确构建应用程序 blob。

除此之外，新日志中还存在许多严重错误。

WEBrick 不应该是在 Heroku 上运行的服务器——这是一个危险信号。您知道 WEBrick 为何推出吗？

IP 看起来也不正确。

Rails 4.2.1 application starting in production on http://0.0.0.0:4674

这个区 block 中的所有内容都需要修复，我认为这并不容易。将一个工作应用程序从开发推到 Heroku 通常很容易，我不知道你有什么设置会导致它陷入困境。我会查看 Gemfile、生产、rb、application.rb，了解“开发”与“生产”之间的所有差异

我希望我能得到一个简单的答案，但我没有。我认为有几个部署问题需要解决，一次一个。

我的建议是缩小应用程序规模，或者从虚拟测试应用程序开始并分阶段部署。

或者也许有人会提供完整的答案......
