django - 错误 404 Nginx 找不到媒体文件。 + Django

Question

我正在使用 nginx 设置基本的 Django 站点。当我导航到文件的 URL 时，出现错误 404 Not Foundnginx/1.18.0 (Ubuntu)

这是配置文件

upstream django {
    server unix:///home/jo/testproject/testproject.sock;
}
# configuration of the server
server {
    listen      80;
    server_name _;
    charset     utf-8;

    # max upload size
    client_max_body_size 75M;

    # Django media and static files
    location /media/  {
    alias /home/jo/testproject/media/;
    }
    location /static {
        alias /home/jo/testproject/static;
    }

    # Send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
        include     /home/jo/testproject/uwsgi_params;
    }
}

媒体文件夹在/home/jo/testproject/media 里面我有 media.gif，但是 ip/media/media.gif 不工作

当我在浏览器中写入 ip 时，我得到了

感谢您使用 nginx。

我认为我设置的其他一切都正确

Docker + NGINX + Gunicorn + Django

Django 项目:

djangoapp

 - static
 - manage.py
 - requirements.txt  
nginx
 - Dockerfile
 - nginx.conf 
docker-compose.yml  
Dockerfile

码头文件:

FROM ubuntu:20.04

# Prevents Python from buffering stdout and stderr
ENV PYTHONUNBUFFERED 1

RUN mkdir /app

RUN pip3 install -r requirements.txt
WORKDIR /app/

EXPOSE 8000

CMD ["gunicorn3", "-b", "0.0.0.0:8000", "djangoapp.wsgi:application", "--workers=2"]

docker-compose.yml:

nginx/Docker文件:

FROM nginx

RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d/

nginx/nginx.conf:

server {
    listen 80;
    server_name $SERVER_NAME;

    location /static/ {     
        alias /app/static/;
    }

    location /media/ {

    }

    location / {
        proxy_set_header Host $host;
        proxy_pass http://djangoapp1:8000;
    }
}

设置.py:

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATICFILES_DIRS = []

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
