Rails 3 Subdomain与Nginx和Unicorn

我有一个rails应用程序,它通过Capistrano部署到VPS,其设置与this Railscast非常相似。我有mydomain.co.uk和admin.mydomain.co.uk。子域名使用lvh.me和标准Webbrick服务器在本地工作正常,但在生产中,admin.mydomain.co.uk显示与mydomain.co.uk完全相同的内容。

我的routes.rb文件:

class AdminDomain
  def self.matches?(request)
    puts "Sub = #{request.subdomain}"
    request.subdomain.present? && request.subdomain == "admin"
  end
end

MyApp::Application.routes.draw do

  constraints(AdminDomain) do
    scope :module => "admin" do
      match '', to: 'admin#index'

      resources :users
    end
  end

  # All the mydomain.co.uk routes...

我的Nginx配置:

upstream unicorn {
  server unix:/tmp/unicorn.<%= application %>.sock fail_timeout=0;
}

server {
  listen 80;
  root <%= current_path %>/public;

  server_name mydomain.co.uk admin.mydomain.co.uk;

  listen 443 ssl;
  ssl_certificate /home/deployer/mydomain_combined.crt;
  ssl_certificate_key /home/deployer/mydomain.key;
  proxy_set_header X-Forwarded-Proto $scheme;

  auth_basic            "Restricted";
  auth_basic_user_file  htpasswd;

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

  location = /favicon.ico {
    expires    max;
    add_header Cache-Control public;
  }

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

  error_page 503 @maintenance;

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

  try_files $uri/index.html $uri @unicorn;
  location @unicorn {
    proxy_set_header X-Forwarded-Proto $scheme;
    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;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

我唯一的想法是Nginx没有将请求网址传递给独角兽。我有一个与SSL类似的问题,但通过添加proxy_set_header X-Forwarded-Proto $scheme;解决了这个问题。如何在Nginx和Unicorn下的生产环境中使子域正常运行?

似乎在我的生产设置中request.subdomain设置为'admin.mydomain',而在开发中它只是'admin'。

因此,使用正则表达式将其添加到routes.rb中可以在本地和我的生产服务器上运行:

constraints :subdomain => /admin.*/ do
  scope :module => "admin" do
    root to: 'admin#index'
  end
end
