【问题描述】：

我对 AWS Elastic Beanstalk 有点陌生 我使用 AWS Elastic Beanstalk 为 Laravel 项目创建了一个 php 7 部署，该项目可以在我的笔记本电脑上完美运行。然后上传我的 Laravel 项目文件，编辑 .env 文件 现在我收到 404 Not Found 错误 在弹性 beanstalk 控制台上，服务器的运行状况良好，但我仍然收到 404 not found 错误。请帮我解决这个问题 我可以创建一个允许我通过 ssh 访问 ec2 的 IAM 用户或笔文件吗？ 如何修复 404 NOT FOUND 错误，因为我无法查看和访问由 Elastic beanstalk 创建的 ec2 中的文件 查看下面服务器的日志

【问题讨论】：

我真的很难过，因为世界上没有人能帮我解决这个问题:(

直接访问 Elastic Beanstalk 实例的最简单方法是通过 EB CLI。安装 CLI 并对其进行正确配置后，您可以使用以下命令：eb list、eb use、eb ssh 查看、配置和访问您的 EB 应用程序和实例。您还可以在包含的屏幕截图的第三个选项卡中直接找到 SSH 的说明。最后，EB 不利用.env 文件。环境变量在 EB Admin online 的 Configuration > Software > Environment properties 部分定义。

我在另一台服务器上重新测试了上传的文件夹，发现文件夹结构存在问题并修复了它，现在很好 感谢您的投入
