你可以使用配置文件来定制你的nginx配置。
1.在源包的顶层创建.ebextensions目录。
1.创建一个配置文件/your_app/.ebextensions/custom.config。在配置文件中键入以下内容以配置转发设置。（我已经创建了一个gist）

files:
  "/etc/nginx/conf.d/custom.conf" :
    content: |
      server {
        listen 8080;
        server_name foo.chief-motp.com;
        location / {
          proxy_pass  http://nodejs/foo/;
          proxy_set_header   Connection "";
          proxy_http_version 1.1;
          proxy_set_header        Host            $host;
          proxy_set_header        X-Real-IP       $remote_addr;
          proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
         }
         location /public {
           alias /var/app/current/public;
         }
      }
      server {
        listen 8080;
        server_name bar.chief-motp.com;
        location / {
          proxy_pass  http://nodejs/bar/;
          proxy_set_header   Connection "";
          proxy_http_version 1.1;
          proxy_set_header        Host            $host;
          proxy_set_header        X-Real-IP       $remote_addr;
          proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        location /public {
          alias /var/app/current/public;
        }
      }

定制Elastic Beanstalk EC2示例的另一种方法是使用CustomAMI。要了解更多信息，可以参考我的帖子。
