rails puma nginx開發模式localhost

Question

該場景是我已經在aws上創建了一個實例，並且克隆了我的rails項目，並在localhost：3000上使用rails s命令運行。並且服務器正在使用PUMA運行。

現在我想看到的公共DNS是http://ec2-13-56-156-255.us-west-1.compute.amazonaws.com/

對我有安裝nginx的Web服務器和我能看到nginx的默認索引頁，但是當我提出變更運行我的應用程序看到我的應用程序在nginx.conf文件中給我403錯誤。變化如下。

文件路徑：/etc/nginx/nginx.conf
