django - 尝试使用 Foreman 在 Gunicorn 上本地运行 Django 应用程序

Question

我正在关注Getting Started with Django on Heroku tutorial
当我尝试使用 Foreman 在 Gunicorn 上运行 Django 应用程序时，我收到下一个错误回溯:

SIGTERM received

Procfile位于项目的根目录中，包含:

web: gunicorn hepcat_server.wsgi

settings.py位于hepcat_server目录

当我使用$ python manage.py run_gunicorn
Gunicorn 启动成功，我看到默认的 Django 页面

我在遵循您使用的 Heroku 设置页面时遇到了同样的问题。我在this page上找到了解决方案。我已将其复制在这里供后代使用:

In the root directory of your django project, create the Procfile file. then write this on it web: sh -c "cd djangoproject && gunicorn djangoproject.wsgi". then create another file called .env in the same location, write DJANGO_SETTINGS_MODULE=djangoproject.settings into it, this will help you setting the required env variable that cannot be set in djangoproject.wsgi module. run foreman start in order to test. What this does should be self explanatory giving the issue below.

When you deploy, after creating your application in heroku, set the env variable with this command heroku config:set DJANGO_SETTINGS_MODULE=djangoproject.settings, this is because the deployment fails before the file djangoproject/djangoproject/wsgi.py is run.

记住将“djangoproject”替换为您的 django 项目的名称。
