Nginx和独角兽上的多个Rails应用程序

我使用Screencast 335部署到VPS教程成功设置了Rails站点.现在，我想在新域上添加另一个Rails应用程序，但是我对所需的步骤感到困惑.

I successfully setup a rails site using the Screencast 335 deploy to a VPS tutorial. Now I want to add another rails app on a new domain but I am confused about the steps required.

在上述设置中，可用站点或/etc/nginx/nginx.conf均未更改.唯一的配置是在我的应用程序配置目录中的unicorn.rb，unicorn_init.sh和nginx.conf中. nginx.conf文件如下所示:-

In the above setup, there are no changes to sites-available or /etc/nginx/nginx.conf. The only configuration is in unicorn.rb, unicorn_init.sh and nginx.conf in my apps config directory. The nginx.conf file looks like this:-

upstream unicorn {
  server unix:/tmp/unicorn.my_app.sock fail_timeout=0;
}
server {
  listen 80 default deferred;
  # server_name my_app.com.au www.my_app.com.au;
  root /var/www/my_app/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;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

在我的Capistrano食谱中，我有这行

In my Capistrano recipe I have this line

sudo "ln -nfs #{current_path}/config/nginx.conf /etc/nginx/sites-enabled/#{application}"

添加第二个域仅仅是为了删除侦听后延迟的默认值，并取消注释server_name节，然后为第二个应用程序使用不同的上游套接字名称和服务器名称重复此配置文件吗?那行得通吗?还是我需要将此文件传输到可用站点并创建到启用站点的符号链接?

Is adding a second domain merely a matter of removing default deferred after listen and un-commenting the server_name section then repeating this config file with a different upstream socket name and server name for the second app? Will that work or do I need to transfer this file to sites-available and create a symbolic link to sites-enabled?
