Django 内部服务器 500 错误 AWS Elastic-Beanstalk 问题

Question

如何修复 AWS eb 部署的应用程序上的 Django Internal Server 500 错误？

我是否需要在我的 base.py 文件中更改我允许的主机，以便在 elasticbeanstalk 中拥有 ec2 的 IP 地址？

# SECURITY WARNING: keep the secret key used in production secret!
# Raises ImproperlyConfigured exception if SECRET_KEY not in os.environ
SECRET_KEY = env('SECRET_KEY')

ALLOWED_HOSTS = []

# Application definition

INSTALLED_APPS = (
    'django.contrib.auth',
    'django_admin_bootstrapped',
    'django.contrib.admin',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
)

...

STATIC_URL = '/static/'

ALLOWED_HOSTS = []

...

我启用了调试并运行了 eb 配置和 eb 日志。 eb deploy 值显示在下方，eb logs 值显示在下方。如何解决“没有名为 django 的模块”的问题？

    Creating application version archive "app-3e17-161020_112522".
Uploading pronet/app-3e17-161020_112522.zip to S3. This may take a while.
Upload Complete.

INFO: Deploying new version to instance(s).                         
INFO: New application version was deployed to running EC2 instances.

下面提供的是 eb 日志的输出。

Answer 1

这是你做的吗？

pip freeze > requirements.txt

如果您不这样做，AWS 将不知道它应该install Django and other dependencies on your EC2 instances for your deployment。

Answer 2

在我的情况下 sqllite 出现错误

从 settings.py 中删除数据库设置并尝试部署

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

然后我配置了 AWS RDS。
