在上一篇文章中項目中使用了webscoket進行實時通信,可是生產環境又使用了django+nginx+uwsgi的部署方式,咱們都知道uwsgi並不能處理websocket請求,因此須要asgi服務器來處理websocket請求,官方推薦的asgi服務器是daphne,下面將介紹詳細的部署步驟。html
以前已經寫過一一篇關於django+nginx+uwsgi的部署方式地址:http://www.javashuo.com/article/p-margylwh-bu.html,這裏就很少說了,如下介紹daphne、supervisor、以及nginx代理websocket的安裝配置。python
項目配置文件目錄(wsgi.py同級)下創建立文件asgi.py,加入應用:nginx
""" ASGI entrypoint. Configures Django and then runs the application defined in the ASGI_APPLICATION setting. """ import os import django from channels.routing import get_default_application os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings") django.setup() application = get_default_application()
啓動daphne 測試是否正常運行(成功之後退出)web
daphne -p 8001 devops.asgi:application
supervisor是由python實現的一個進程管理工具,能夠確保所管理的進程一直運行,當進程一點中斷supervisord會自動進行重啓。django
安裝步驟:服務器
#yum安裝: yum install python-setuptools easy_install supervisor 或者 yum install -y epel-release yum install -y supervisor #手動安裝: wget https://pypi.python.org/packages/source/s/supervisor/supervisor-3.1.3.tar.gz tar zxf supervisor-3.1.3.tar.gz cd supervisor python setup.py install #pip安裝: pip install supervisor
生成配置文件websocket
echo_supervisord_conf > /etc/supervisord.conf
編輯/etc/supervisord.conf加入配置app
[program:daphne] directory=/opt/app/devops #項目目錄 command=daphne -b 127.0.0.1 -p 8001 --proxy-headers devops.asgi:application #啓動命令 autostart=true autorestart=true stdout_logfile=/tmp/websocket.log #日誌 redirect_stderr=true
啓動supervisorsocket
supervisord -c /etc/supervisord.conf
啓動或者中止daphne工具
supervisorctl start daphne
supervisorctl stop daphne
修改nginx配置文件
#####轉發配置 upstream wsbackend { server 127.0.0.1:8001; } ######location配置 location /ws/deploy { proxy_pass http://wsbackend; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; }
