Ruby on rails 使用弹性beanstalk部署的Rails应用程序响应为；站点可以'；“联系不到”；

我构建了一个rails应用程序，其堆栈如下：

Puma（应用服务器）3.0

RubyonRails 5.0

Postgresql 9.5.3

我尝试将此应用程序部署到aws elastic beanstalk，并成功完成了部署。但是，当我尝试访问beanstalk生成的web地址时，应用程序服务器没有受到影响。几分钟后，浏览器抛出“无法访问站点”

以下是必要的日志：

美洲狮原木

/var/log/nginx/error.log

/var/app/containerfiles/logs/production.log

尽管多次重新加载，此production.log仍保持原样。我无法在任何日志中获取任何错误

供进一步参考：

以下是我的几个其他文件：

config/puma.rb

Gemfile

我甚至尝试更改根路径的控制器以呈现一个简单的hello，而不是尝试从数据库获取数据。但是主要的问题似乎是请求没有到达应用程序，从production.log中的零日志条目可以看出这一点

我还尝试删除Gemfile中提供的puma版本号，希望更新的版本能够解决这个问题

我还多次尝试重新启动nginx服务器和应用程序服务器。但似乎没有什么能够抛出一个有意义的错误

为了确保这不是数据库问题，我将ssh插入eb cli，并使用rails控制台。控制台工作得很好。因此，这不是一个数据库问题

如果有人能帮我解决问题，至少能在日志中给我一个有意义的错误，我将不胜感激

我在朋友的笔记本电脑上打开了url。它打开了。问题似乎出在我的系统代理上。现在我可以删除我的系统代理，但我不能确定我的用户是否会访问我的网站。有没有一种方法可以将elastic beanstalk与系统代理一起使用？同时，我也会在互联网上为同样的事情而爱抚

编辑3： 我试着用笔记本电脑从safari打开网站。它起作用了。但谷歌Chrome无法实现这一功能

我从浏览器中清除了缓存，它成功了！吸取的教训。

将rails应用程序部署到elastic beanstalk后，我遇到了504网关超时错误。在应用程序的根目录中添加名为“Procfile”（无扩展名）的文件，其中包含

web: bundle exec puma -C /opt/elasticbeanstalk/config/private/pumaconf.rb

---

解决了我的问题。

您是否正确设置了ngnix.conf？如果你也可以发布你的nginx.conf文件？@sahil请看一看。.我已经添加了nginx配置文件。root应该指向，

/path/to/code\u folder/public

。下面是一个我用于在Pushion passenger、Nginx和Rails上运行的多个应用程序的示例。将此

config.force\u ssl=true

更改为

false

解决了问题。我花了好几天时间想弄明白这一点
