我如何弄清楚部署出了什么问题？

我在这里遵循写得很好的教程：https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-unicorn-and-nginx-on-ubuntu-14-04。

在我开始使用NginX运行服务器之前，一切都顺利进行。当我到达运行命令RAILS_ENV=production rails server --binding=server_public_IP的位置时，我能够跳到网络上的另一台机器并使用浏览器访问该页面。

一旦我走到尽头，我觉得我没有任何打嗝或任何事情到达那里，但我不能让页面出现了，我不知道怎么弄清楚什么是错误。我假设我的服务器正在运行，但这里有一些有用的信息：

当我在nginx上运行服务状态时：

<user>@aws-ubuntu:~/<app>$ sudo service nginx status
● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)

当我在unicorn_<app>上运行服务状态时：

<user>@aws-ubuntu:~/<app>$ sudo service unicorn_<app> status
● unicorn_<app>.service - LSB: starts the unicorn app server
   Loaded: loaded (/etc/init.d/unicorn_<app>)

  Process: 2848 ExecStart=/etc/init.d/unicorn_<app> start (code=exited, status=0/SUCCESS)

netstat for port：

<user>@aws-ubuntu:~/<app>$ sudo netstat -ntlp | grep LISTEN
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      2826/nginx -g daemo

Azure上的端点：

最后，我不知道这是否有帮助，但这是服务器实际上能够从内部做出响应：

<user>@aws-ubuntu:~/<app>$ curl localhost:8080/tasks
