本人新手，第一次在 linux 上部署 rails，由于周围没有老前辈指引，虽已尝试部署多日，但是总是不成。无奈，来社区发帖，希望前辈们指点一二，小弟万分感激。

部署上是参照社区 wiki：https://ruby-china.org/wiki/rvm-guide 示例，在 ubuntu 上操作，除最后一步安装 nginx 是采用的自行下载源码，通过 rvmsudo passenger-install-nginx-module 外，其他均与示例中保持一致操作。

我本地的 demo 实例，rails s 启动后，是可以通过http://localhost:3000/say/hello,正常访问，但是，通过 sudo /opt/nginx/sbin/nginx 启动 nginx 后，本地访问http://localhost/say/helloIncomplete时，总是提示‘response received from application’

以下是 nginx 的配置文件

我之前项目用的是 rails2.3.4，没有见过这种错误。看来我还有不少知识要更新

看了链接，才明白是怎么回事。十分感谢！（话说，要不是看了链接，我都不知道 production 还不能访问）

不过还有一个问题想问。我刚才将默认的 development 的密钥拷贝到了 production 下一份。然后发现 production 模式下，页面可以正常访问了。但是我不是很明白这个密钥写在 secrets.ym 中和写在环境变量中，有什么区别？我拷贝一个密钥和生成一个密钥有什么区别？还有都说这个密钥是为了安全性，怎么体现出来的？
