Ruby on rails 在我的Rails生产服务器上，每个页面都返回一个错误

使用以rails s-e production启动的生产服务器时，我访问的每个页面都会返回此错误：

We're sorry, but something went wrong.
If you are the application owner check the logs for more information.

我不知道错误是什么意思，即使每次都是相同类型的错误，尽管每次都是相同的文本

有人知道为什么会这样吗

config/environments/production.rb：

Website::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # Code is not reloaded between requests.
  config.cache_classes = true

  # Eager load code on boot. This eager loads most of Rails and
  # your application in memory, allowing both thread web servers
  # and those relying on copy on write to perform better.
  # Rake tasks automatically ignore this option for performance.
  config.eager_load = true

  # Full error reports are disabled and caching is turned on.

您忘了为Rails应用程序做一些生产使用准备

确保运行Rails应用程序的用户有权在

log

目录中写入日志

确保您的密钥和rails环境。用于cookies安全的密钥。您只需创建环境变量，Rails就可以检索它

export SECRET\u KEY\u BASE=$（rake SECRET）

Rails env用于告诉您在生产模式下运行的Rails应用程序

export Rails\u env=production

确保数据库配置正确。您需要使用DB适配器配置创建

config/database.yml

，然后运行

rake DB:create

和

rake DB:migrate

确保您的资产已预编译。只需运行

rake资产：预编译

所有这些之后，您可以运行rails s

---

但这不是在生产环境中运行Rails应用程序的正确方法。为了更好、更可靠的生产，您需要使用Nginx作为负载平衡器和备用应用服务器，如Puma或Passenger。

您在log/production.log中的日志会说什么？在终端中键入

heroku logs-a yourappname

，然后查找问题，这样您就知道了，“我们很抱歉”消息是默认的

public/500.html

页面。您将从服务器收到一个500响应，这是一个内部服务器错误。需要考虑的一件事：你的生产数据库存在吗？@hjing我没有生产日志。。。这不好吗？

rakedb:create RAILS\u ENV=production

和

rakedb:migrate RAILS\u ENV=production
