Django: невозможно записать файл из ModelForm на Apache и Mod_wsgi

/ 10 апреля 2020

У меня есть сайт Django 3.0.3, работающий на RHEL 7 и Apache, использующий mod_wsgi. На моей машине разработки (Windows) я могу сохранить файл через тип поля FileField. Однако при развертывании в рабочей среде (RHEL 7 и Apache с использованием mod_wsgi) при попытке сохранить файл выдается ошибка «[ErrNo 13] Permission denied».

Я установил права доступа к папке для drwxrwxrwx. для папки MEDIA_ ROOT для пользователя apache с именем "apache" в моем случае (что подтверждается как вызовом getpass.getuser () внутри программы, так и настройками httpd conf. Это также имя, указанное в mod_wsgi.process_group на странице отладки Django.

Я включил свой соответствующий код и отладку:
