Question

我花了整整一天的时间来解决这个问题，但我还没有得到它。我在digitaloceon中创建了一个Droplet，我安装了rvm并使用mina部署了我的rails应用程序。我创建了交换区域。

所以，我确信我的应用程序路径在nginx配置和routes.rb中是正确的。但是rails也在我的域名和服务器IP上呈现了一个空白的白页。

我检查了unicorn.stder.log我看到了这些日志：

Instance method "open" is already defined in Object, use generic helper instead or set StateMachine::Machine.ignore_method_conflicts = true.

所以这是我的nginx sites-available / myapp.com

upstream app {
    # Path to Unicorn SOCK file, as defined previously
    server unix:/tmp/unicorn.sock fail_timeout=0;
}

server {


    listen 80;
    server_name .mydomain.com;

    # Application root, as defined previously
    root /var/www/myapp/current/public;

    try_files $uri/index.html $uri @app;

    location @app {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://app;
    }

    error_page 500 502 503 504 /500.html;
    client_max_body_size 4G;
    keepalive_timeout 10;
    }

谁能告诉我，有什么问题？请！

查看此修订后的nginx配置是否有效

upstream app {
  # Path to Unicorn SOCK file, as defined previously
  server unix:/tmp/unicorn.sock fail_timeout=0;
}

server {


  listen 80;
  server_name mercandiamond.com www.mercandiamond.com;

  # Application root, as defined previously
  root /var/www/myapp/current/public;

  location / {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_redirect off;
      proxy_pass http://localhost:22/;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
}

如果没有，请确保

1）sites-enabled / myapp.com匹配sites-available / myapp.com

2）运行nginx -s reload

希望这有帮助！
