daphne+nginx+channels+redis 在Ubuntu 24.04布署流程

Python Django 配合 ASGI 服务器（如 Daphne）是实现高并发、异步 Web 应用（如 WebSocket）的标准方式。Django 默认生成 asgi.py 配置文件，支持异步请求处理。ASGI 原生支持 WebSocket：非常适合聊天、实时通知和游戏等实时通信应用
一，创建项目目录，或者从本地调式好的项目打包上传到目标服务器解压后自动生成目录 sudo mkdir -p /home/crash_detector cd /home/crash_detector
二，进入项目目录后创建虚拟环境 python3 -m venv venv 激活虚拟环境 source venv/bin/activate 进入虚拟环境后安装项目所需的包 deactivate (退出虚拟环境)
三， pip install channels daphne channels-redis mysqlclient sudo apt install python3-venv redis-server -y pip install websockets==13.1 aiohttp Django==4.2.5 channels>=4.0.0 channels-redis>=4.1.0 daphne>=4.0.0 aiohttp>=3.9.0 websockets==13.1 mysqlclient==2.2.7 redis>=5.0.0
四，配置 Daphne Service vi /etc/systemd/system/daphne.service 输入下面的内容 [Unit] Description=Daphne Service for Django Channels After=network.target redis-server.service mysql.service [Service] Type=simple User=www-data Group=www-data WorkingDirectory=/home/crash_detector Environment="PATH=/home/crash_detector/venv/bin" ExecStart=/home/crash_detector/venv/bin/daphne -u /run/daphne/daphne.sock crash_detector.asgi:application Restart=on-failure RestartSec=5s [Install] WantedBy=multi-user.target
五，vi /home/crash_detector/crash_detector/asgi.py import os from django.core.asgi import get_asgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'crash_detector.settings') django_asgi_app = get_asgi_application() from channels.routing import ProtocolTypeRouter, URLRouter from channels.auth import AuthMiddlewareStack from monitor import routing application = ProtocolTypeRouter({ "http": django_asgi_app, "websocket": AuthMiddlewareStack( URLRouter( routing.websocket_urlpatterns ) ), })
六，sudo chown -R www-data:www-data /var/www/crash_detector sudo mkdir -p /run/daphne sudo chown www-data:www-data /run/daphne
七，Start services sudo systemctl daemon-reload sudo systemctl start redis-server sudo systemctl enable redis-server sudo systemctl start daphne # Stop Daphne sudo systemctl stop daphne sudo systemctl enable daphne sudo systemctl restart nginx # Restart all services sudo systemctl restart daphne sudo systemctl restart nginx # 7. Check status sudo systemctl status daphne
八，手动测试是否启动项目 cd /home/crash_detector source venv/bin/activate daphne -u /run/daphne/daphne.sock crash_detector.asgi:application
