【中文标题】使用弹性 beantalk 部署的 Rails 应用程序响应“无法访问站点”【英文标题】:Rails app deployed using elastic beanstalk responds with "site can't be reached" 【发布时间】:2017-06-01 23:03:30 【问题描述】:我已经使用以下堆栈构建了一个 rails 应用程序:
-
Puma(应用服务器)3.0
Ruby on Rails 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。但是,当我尝试访问 beanstalk 生成的网址时,应用程序服务器上没有任何命中。几分钟后浏览器抛出“无法访问站点”。
这里是必要的日志:
puma.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发现任何错误。
进一步参考:
这是我的其他几个文件:
config/puma.rb
workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['RAILS_MAX_THREADS'] || 5)
threads threads_count, threads_count
preload_app!

port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'
on_worker_boot do

除此之外,在我个人对google和***的研究之后,我尝试了一些东西:
我将以下内容附加到我的 puma 配置文件 (puma.rb):
bind "unix:///var/run/puma/my_app.sock"
pidfile "/var/run/puma/my_app.sock"
我什至尝试将控制器更改为根路径以呈现简单的问候,而不是尝试从数据库中获取数据。但主要问题似乎是请求没有到达应用程序,这从 production.log 中的零日志条目可以看出。
我还尝试删除 Gemfile 中提供的 puma 版本号,希望更新的版本可以解决此问题。
我也尝试过多次重启 nginx 服务器和应用服务器。但似乎没有什么能够引发有意义的错误。
为了确保这不是数据库问题,我通过 ssh-ed 进入 eb cli,并使用了 rails 控制台。控制台工作得很好。所以,这不是数据库问题。
如果有人可以帮助我,我将非常感激,并且至少在日志中给我一个有意义的错误。

编辑 2:
我在朋友的笔记本电脑上打开了网址。它打开了。看来问题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会访问我的网站。有没有办法将弹性豆茎与系统代理一起使用?同时,我也会在互联网上爱抚。
编辑 3: 我尝试在笔记本电脑中从 Safari 浏览器打开网站。有用。但它不适用于谷歌浏览器。
编辑 4: 我从浏览器中清除了缓存,它起作用了!吸取的教训。
【问题讨论】:
您是否正确设置了您的 ngnix.conf?如果你也可以发布你的 nginx.conf 文件? @sahil 请看一下..我已经添加了 nginx 配置文件。 root 应该指向/path/to/code_folder/public
。这是一个template,我将它用于在 Pushion 乘客、Nginx 和 Rails 上运行的多个应用程序。
将此config.force_ssl = true
更改为false
解决了这个问题。我花了几天时间试图弄清楚这一点
【参考方案1】:
将我的 rails 应用程序部署到弹性 beanstalk 后,我收到 504 网关超时错误。在应用程序的根目录中添加一个名为“Procfile”(无扩展名)的文件,其内容
web: bundle exec puma -C /opt/elasticbeanstalk/config/private/pumaconf.rb
解决了我的问题。
