使用 Gunicorn 设置 Django 应用程序

Question

所以我正在关注这个关于数字海洋的教程：https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-django-with-postgres-nginx-and-gunicorn

我唯一没有做的就是使用数据库引擎，我只是坚持使用SQLite3 引擎，因为应用程序很小。我已经到了尝试运行服务器 wgsi 文件的地步，它显示了不支持导入文件名的错误。我不确定如何解决这个问题。

我试过跑步：

python manage.py run_gunicorn 127.0.0.0:8001

但它说 Unknown command: 'run_gunicorn' 并显示帮助它没有显示 run_gunicorn

这是我的 wgsi 文件（取出项目名称）：

import os

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "xxxx.settings")

from django.core.wgsi import get_wgsi_application
application = get_wgsi_application()

这是回溯：

从 manage.py run_gunicorn 迁移到实际使用 gunicorn 命令时，我遇到了类似的问题。我发现除了实际的 wsgi 文件之外，我还必须设置 DJANGO_SETTINGS_MODULE 和设置。

我的项目结构：

• eetecnet/
  • manage.py
  • eetecnet/
    • eestecnet.wsgi
    • 设置/
      • deployment.py

我从根 eestecnet 文件夹运行以下命令：

gunicorn --env DJANGO_SETTINGS_MODULE=eestecnet.settings.deployment --settings eestecnet.settings.deployment eestecnet.wsgi

在我的设置中我还指定：

WSGI_APPLICATION = 'eestecnet.wsgi.application'

希望对你有所帮助。
