使用nginx + gunicorn服务在django部署中未显示的媒体

Question

我正在使用Nginx和gunicorn服务在VPS（debian 9）中部署django应用程序。 一切都按预期工作，但不显示用户在媒体文件中上传的图像，404（未找到）。 当我使用Debug=True图像时，静态文件在开发和生产中正常工作。

为了运行这个应用程序，我创建了一个没有sudo权限的webuser和一个名为webapps的组。 由于看起来nginx看不到媒体我已经将组更改为www-data，但仍然无法正常工作。 这里有一个类似的问题，但没有一个公认的答案。 任何帮助都感激不尽。

Bellow一些重要的配置：

Gunicorn服务于/etc/systemd/system/gunicorn.service

我的nginx配置

server {
    listen         80;
    server_name    mysite.com;
    client_max_body_size 100M; #to have space to load images
    return         301 https://$server_name$request_uri;
}

server {
    listen         443 ssl;
    server_name    mysite.com www.mysitet;
    client_max_body_size 100M; #to have space to load images

    ssl on;
    ssl_certificate /etc/letsencrypt/live/mysite.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/mysite.com/privkey.pem;

    location /static/ {
            autoindex on;
            alias /home/webuser/DjangoProject/web_project/static/;
    }

    location /media/ {
            autoindex on;
            alias /home/webuser/DjangoProject/web_project/media/;
    }

    location / {
            include proxy_params;           
            proxy_pass http://unix:/home/webuser/DjangoProjects/web_project/run/gunicorn.sock;

    }
}

我的settings.py的一些部分

import os
import json

with open('/etc/config.json') as config_file:
    config = json.load(config_file)

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


SECRET_KEY = config['SECRET_KEY']
DEBUG = False
ALLOWED_HOSTS = ['mysite.com', '198.XX.XX.XXX']

INSTALLED_APPS = [
  'blog.apps.BlogConfig',
  'users.apps.UsersConfig',
  'crispy_forms',
  'django.contrib.admin',
  'django.contrib.auth',
  'django.contrib.contenttypes',
  'django.contrib.sessions',
  'django.contrib.messages',
  'django.contrib.staticfiles',
]

ROOT_URLCONF = 'web_project.urls'

TEMPLATES = [
  {
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [
        ''
    ],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages',
        ],
    },
  },
]

WSGI_APPLICATION = 'web_project.wsgi.application'

DATABASES = {
  'default': {
    'ENGINE': 'django.db.backends.postgresql',
    'NAME': 'dbname',
    'USER': 'webuser',
    'PASSWORD': 'dbpassword',
    'HOST': 'localhost',
    'PORT': '',
  }
}

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

在urls.py我添加了

urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

当然，每次更改后我都会用

sudo systemctl restart nginx
sudo pkill gunicorn
sudo systemctl daemon-reload
sudoo systemctl start gunicorn

原始图片是StackOverFlowPicture.png，但知道我有另一张图片

webuser@:~/DjangoProjects/web_project/media/profile_pics$ ls
StackOverFlowPicture.png  StackOverFlowPicture_TL8URPF.png

感谢Ivan Starostin，他评论了我的拼写错误DjangoProjects != DjangoProject和我的上次日志错误

2019/06/20 11:06:46 [error] 22983#22983: *1 open() "/home/webuser/DjangoProjects/web_project/media/media/profile_pics/StackOverFlowPicture_TL8URPF.png" failed (2: No such file or directory), client: 109.132.217.176, server: example.com, request: "GET /media/profile_pics/StackOverFlowPicture_TL8URPF.png HTTP/1.1", host: "example.com", referrer: "https://example.com/"

我通过改变解决了这个问题

location /media/ {
        autoindex on;
        alias /home/webuser/DjangoProject/web_project/media/;
}

至

location /media/ {
        autoindex on;
        alias /home/webuser/DjangoProject/web_project;
}

现在图片已加载。 谢谢你的帮助！
