невозможно использовать sqlalchemy с WSGI

0 голосов
/ 06 июля 2019
  • Я новичок в кодировании и пытаюсь завершить свой проект развертывания.
    1. Я установил виртуальную машину на Google Compute Engine
    2. Установить apache2
    3. Установить python3, flask .... все зависимости
    4. тестирование путем успешного запуска скрипта через python3 project.py, возможность подключения с публичного IP-адреса, порт 8080

А вот и проблемы: 1. Я изменяю apache2, чтобы добавить project.conf и port.conf для разрешения virtualhost.
Это не подойдет для моего веб-приложения project.py, но позволит всем загружать файлы. 2. Я устанавливаю версию WSGI python3, myapp.wsgi, чтобы вернуть hello world для тестирования, который работает. Но как я переключаюсь на из приложения импорта проекта как приложения, он возвращает 500 Внутренняя ошибка сервера. 3. Я добавил sudo chmod a + x myapp.wsgi, но это не решает проблему
