Puma 未运行生产 ec2

Question

我正在尝试使用 nginx、puma 和 capistrano 将我的网站部署到 amazon ec2 我遵循了本教程 https://medium.com/@henslejoseph/deployment-a-rails-app-to-ec2-using-bitbucket-and-semaphoreci-d539bea90db3 应用程序已部署到服务器但是当我尝试通过浏览器访问它时访问网站 url 它说这个网站不能 reached.The 接下来我尝试检查 nginx 和 puma 日志我在 nginx 日志中没有找到任何东西但是在 puma_access.log 中有错误 Errno::EADDRINUSE：地址已在使用 - bind(2) for "0.0.0.0" port 3000.After 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。我尝试从 3 天开始对其进行调试，但仍然不知道什么是 going.Any 非常感谢帮助我只是附上我所有的配置文件以供参考。

谁能帮我解决我哪里出错的问题已经尝试了所有 Whosebug 问题并在 3 天内用谷歌搜索了很多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 中可用 folder.This 默认文件确保该网站是 enabled.If 默认文件不是似乎 nginx 没有在端口 80 上监听。
