django - 通过 AWS Elastic Beanstalk 成功部署 Django，但出现 500 错误

Question

上周我一直坚持这一点，对于接下来的步骤我很迷茫。

我有一个使用 MySQL 数据库的 Django 应用程序。我使用 AWS Elastic Beanstalk 使用以下教程部署了它:https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html

它成功部署。但是，在尝试访问该站点时，我不断收到 500 个错误。我也更新了主机值。

这是error_log，但我无法从中推断出太多。

您可以尝试在您的 ec2 上安装 ssl 模块: sudo yum install mod_ssl 解决您的 httpd 问题。

此外，如果您使用的是负载均衡器，您可能需要检查目标的运行状况。当运行状况检查失败时，您会收到 500 个错误。
