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

😅 把错误仔细看一遍

Exception RuntimeError in Rack application object (Missing `secret_key_base` for 'production' environment, set this value in `config/secrets.yml`) 

看错误信息

就是看不明白才会问的😅 ,不过还是谢谢你

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

gakki 回复

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?
