ami-0d44833027c1a3297是一个带有 hello world index.html 的 ubuntu AMI/home/ubuntu/

虽然，我没有收到任何错误，并且 ec2 实例已启动并正在运行，但 http 服务器没有运行。

注意：如果我手动 ssh 并在内联部分应用相同的命令集，我能够成功运行 http 服务器。任何帮助，将不胜感激！

使固定：

inline = [
      ....
      "sleep 20",
    ]

我相信供应商在服务器进程开始之前退出（竞争条件），因此睡眠是必要的。

注意：从 Hashicorp Packer 文档（https://www.packer.io/docs/provisioners/shell.html）中获得了睡眠的想法
