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访问它时通过访问网站url它说这个网站是无法到达的。接下来我尝试的是检查nginx和美洲狮日志我在nginx日志中找不到任何问题，但是在puma_access.log中有错误Errno :: EADDRINUSE：地址已经在使用 - bind（2） for＆＃34; 0.0.0.0＆＃34;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连接到端口。我试图从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的所有配置文件以供参考。

有人可以帮助我，在我出错的地方尝试了所有的stackoverflow问题并且从3天开始搜索了很多，但仍然不知道我的配置是否有错。

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

Puma没有在生产ec2中运行
