Puma 没有在生产 ec2 中运行

Question

我正在尝试使用 nginx、puma 和 capistrano 将我的网站部署到 amazon ec2 我按照本教程 https://medium.com/@henslejoseph/deployment-a-rails-app-to-ec2-using-bitbucket-and-semaphoreci-d539bea90db3 将应用程序部署到服务器但是当我尝试通过浏览器通过浏览器访问它时转到网站 url 它说这个网站无法访问。我尝试的下一件事是检查 nginx 和 puma 日志，我在 nginx 日志中找不到任何东西，但在 puma_access.log 中有错误 Errno::EADDRINUSE: Address already in use - bind(2) for " 0.0.0.0" 端口 3000。在此之后，我尝试使用 lsof -wni tcp:3000 和 netstat -an | 检查是否有任何进程正在使用端口 3000 grep 3000 但输出为空似乎没有进程附加到端口。 我正在尝试从 3 天开始调试它，但仍然不知道发生了什么。非常感谢任何帮助我只是附上我所有的配置文件以供参考。

有人可以帮我解决问题的地方吗？我已经尝试了所有 stackoverflow 问题，并且从 3 天开始在 Google 上搜索了很多，但仍然不知道我的配置有什么问题。

更新：经过大量研究，我得到了解决方案 您所要做的就是确保sites_available 文件夹中的默认文件也应该在sites_enabled 文件夹中可用。此默认文件确保网站已启用。如果默认文件不可用，则似乎nginx 没有在端口80 上侦听。
