502坏网关错误(nginx +独角兽+数字海洋)

标签: ruby-on-rails-3 nginx unicorn gateway digital-ocean

我挣扎了几个小时来解决这个问题,但仍然没有用。我在浏览器中看到的错误是:

POST / users 502(Bad Gateway)

我知道这是设置nginx和独角兽的问题,但我无法解决它。顺便说一句,我使用数字海洋部署了我的代码。这是我的配置文件


Unicorn config(nginx.conf):

 user              nginx;
 worker_processes  1;
 error_log  /var/log/nginx/error.log;
 pid        /var/run/nginx.pid;

  worker_connections  1024;

   default_type  application/octet-stream;

   log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

                  '"$http_user_agent" "$http_x_forwarded_for"';

   access_log  /var/log/nginx/access.log  main;

   sendfile        on;
   #tcp_nopush     on;

   #keepalive_timeout  0;
   keepalive_timeout  65;

   #gzip  on;

   # Load config files from the /etc/nginx/conf.d directory
   # The default server is in conf.d/default.conf

}

Unicorn配置文件(/var/nginx/unicorn.conf):

    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_redirect off;
    proxy_pass http://unicorn;
  }

  if (-f $document_root/system/maintenance.html) {
    return 503;
  }

  error_page 500 502 504 /500.html;
  location = /500.html {
    root /var/www/quoine/current/public;
  }

  error_page 503 @maintenance;
  location @maintenance {
    rewrite  ^(.*)$  /system/maintenance.html break;
  }
}

我正在使用Rails 3.如果有人对这个问题有所了解,请告诉我。我花了3个小时没有任何进展。感谢

你能提供你为独角兽所拥有的配置吗(你提供的文件都是针对nginx的)。它应该是什么样子的一个例子是在这里的“配置服务器”条目的第一部分:https://www.digitalocean.com/community/tutorials/how-to-deploy-rails-apps-using-unicorn-and-nginx-on-centos-6-5

我试图找出为什么在使用Digital Ocean的一键安装后使用不同版本的Ruby时出现502错误的原因。

我通过查看本指南找到了答案:https://www.digitalocean.com/community/tutorials/how-to-use-the-1-click-ruby-on-rails-on-ubuntu-14-04-image

我的问题是指南中的以下内容:

  

默认情况下,您拥有正在使用的Ruby位置   更改/ etc / default / unicorn路径名以包含/ usr / local / rvm / rubies   新安装的子文件夹和/ usr / local / rvm / gems子文件夹   版本以及独角兽的位置

希望这有助于帮助某人
