ssl - 如何重启 httpd 以在 Elastic Beanstalk 中的 EC2 实例上启用 HTTPS？

Question

问题

我正在尝试在 Elastic Beanstalk 中的 EC2 实例上启用 HTTPS。我在 .ebextensions 目录中有一个 https-instance.config 文件，其中包括停止和启动 httpd 服务器。原始容器命令是这些(来自 AWS 文档 here ，并且在我的问题中也提到了 here :

container_commands:
  01killhttpd:
    command: "killall httpd"
  02waitforhttpddeath:
    command: "sleep 3"

但是，我收到以下错误，详细信息在 cfn-init.log 中:

我已尝试从 https-instance.config 中删除此重新启动，它会构建但无法连接到 HTTPS。我还尝试用其他命令替换上述命令以重新启动 httpd 服务器，但这些命令导致的错误与上面的错误几乎相同:

container_commands:
  01restart:
    command: "systemctl restart httpd"

和

container_commands:
  01restartservice:
    command: "systemctl restart httpd.service"

问题

如何重新启动 httpd 服务器以允许 HTTPS 连接到我的应用程序？

上下文

• 亚马逊 Linux 2
• Python 3.7 环境中的 Flask 应用
• 使用单个 EC2 实例，因此没有负载均衡器
• 我只需要这个用于开发目的

这是我从 AWS 获得的完整 https-instance.config:

Answer 1

您的命令失败的原因是在 Amazon Linux 2 上Python 3.7 环境没有没有httpd(它是物理安装的，但不是事件的)。您可以通过 sshing 进入实例并运行来验证这一点:

sudo systemctl status httpd

相反，there are nginx 和 gunicorn 作为 wsgi。您提供的 AWS 文档链接适用于 Amazon Linux 1，而不是 2。

因此，应该使用 nginx 设置 SSL 证书和 HTTPs config files在 .platform/nginx/conf.d/ 文件夹中。
