Question

我遵循此DigitalOcean指南，使用Nginx + Puma + Capistrano设置了RoR应用程序：

https://www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma

我能够设置所有内容并使Capistrano部署正常工作，但是当我使用它的IP访问我的Droplet时，它会继续加载页面，但没有任何显示。连接基本上超时。

nginx日志和Puma日志（access + error）均未显示任何内容。不过，Puma和nginx都在运行。

Ping显示服务器IP是可访问的，所以我认为这与在此Droplet上运行的Web服务器有关

可能是什么原因，以及如何对其进行调试？

这是nginx的配置：

upstream puma {
  server unix:/home/deployer/apps/<my-app>/shared/tmp/sockets/<my-app>-puma.sock;
}

server {
  listen 80 default_server deferred;
  # server_name example.com;

  root /home/deployer/apps/<my-app>/current/public;
  access_log /home/deployer/apps/<my-app>/current/log/nginx.access.log;
  error_log /home/deployer/apps/<my-app>/current/log/nginx.error.log info;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  try_files $uri/index.html $uri @puma;
  location @puma {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://puma;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 10M;
  keepalive_timeout 10;
}

这是deploy.rb文件：

  before :starting,     :check_revision
  after  :finishing,    :compile_assets
  after  :finishing,    :cleanup
# after  :finishing,    :restart

# ps aux | grep puma    # Get puma pid

使用Capistrano和NGinx安装RoR应用程序后，Digital Ocean Droplet服务器超时
