問題排序。 顯然股票OpsWorks獨角獸食譜有參考ActiveRecord。 所以通過評論/刪除before_fork..end和after_fork..end的整個塊。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

我們需要利用襪子文件，而不是在nginx的端口的方法，所以對於我們的應用程序是非常有益的。

還有兩個任務是覆蓋股票獨角獸的默認鍵值，並使用shared/script/unicorn腳本作爲部署用戶自動啓動。
