AWS Elastic Beanstalk Django 网站不会显示

如何解决AWS Elastic Beanstalk Django 网站不会显示

我已经使用 Django 1.11 设置了 python3.6/Amazon Linux 的 Elastic Beanstalk。该应用程序已通过 EB CLI 成功上传并安装。

INFO    deploying new version to instance(s).
INFO    New application version was deployed to running EC2 instances.
INFO    Environment update completed successfully.

设置 .config 文件没有错误：

option_settings:
  aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: myproject.settings
    SECRET_KEY: TempKey

  aws:elasticbeanstalk:container:python:
    WsgiPath: myproject/wsgi.py

EB 可以很好地解析 wsgi.py。

我已经在 ALLOWED_HOSTS 中包含了当前的 EB 地址（如 projectname.us-west-1.elasticbeanstalk.com）。

然而，在所有这些“无错误”过程之后，实际的网站并没有出现。（而 EB 示例应用程序正在运行）甚至根本没有 400、500 错误消息页面。无论 DEBUG=True 还是 False，都没有 Django 错误消息。只是浏览器显示一个空白的超时页面。

当我使用 python manage.py runserver 在本地环境中运行 Django 时，它运行良好。

一些可疑的部分如下：

INFO  [3223]  - [Application deployment app-51cc-29999@52/StartupStage1/AppDeployEnactHook/01flip.py] : Completed activity. Result:
  httpd: stopped
  httpd: started
  httpd                            RUNNING   pid 20456,but root page is not responding in 3 seconds.

和，

127.0.0.1 (-) - - [+0000] "GET / HTTP/1.1" 301 - "-" "Python-urllib/2.7"

我尝试在 EC2 SSH 上手动重新启动 httpd，刷新 EB 环境和应用程序，使用 https 和 HTTP，使用 EC2 IP 地址，然后从头开始重新启动，但没有奏效。

有解决问题的线索吗？
