Rails 生产日志不更新

Question

我使用的是 Rails 6.0.3

在生产中，我尝试在生产日志上运行 tail -f，但当我对应用程序执行任何操作时，我没有收到更新。有什么想法吗？

我尝试对 production.log 文件应用 0644 权限，但这不是问题，因为文件中有数据。

我也在使用 nginx 和 puma。

生产日志：

production.rb

Rails.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 threaded web servers
  # and those relying on copy on write to perform better.
  # Rake tasks automatically ignore this option for performance.

  config.consider_all_requests_local       = false

  # Apache or NGINX already handles this.

end

提前致谢。

我通过将这些行添加到我的生产文件中解决了我的问题： config.logger = Logger.new (Rails.root.join("log/production.log"))

并在生产服务器上重新启动 cougar。
