AWS OpsWorks中未建立ActiveRecord :: Connection

Question

我已經嘗試過各種解決方案，包括下面的解決方案，但仍然遇到相同的錯誤。 贊賞任何線索。

在Rails 3.2中使用Mongoid時刪除database.yml

問題已排序。 顯然，《 OpsWorks獨角獸食譜》參考了ActiveRecord。 因此，通過注釋/刪除before_fork..end和after_fork..end的整個塊，可以幫助我們部署使用mongoid的應用程序。

https://github.com/aws/opsworks-cookbooks/blob/master-chef-11.4/unicorn/templates/default/unicorn.conf.erb

我們需要利用Sock文件而不是NginX中的port方法，因此對我們的應用程序非常有益。

還有兩個任務是從股票unicorn覆蓋默認鍵值，並以部署用戶的身份使用共享/腳本/ unicorn腳本自動啟動。
