在上一篇文章中项目中使用了webscoket进行实时通信,可是生产环境又使用了django+nginx+uwsgi的部署方式,咱们都知道uwsgi并不能处理websocket请求,因此须要asgi服务器来处理websocket请求,官方推荐的asgi服务器是daphne,下面将介绍详细的部署步骤。html
以前已经写过一一篇关于django+nginx+uwsgi的部署方式地址:http://www.javashuo.com/article/p-margylwh-bu.html,这里就很少说了,如下介绍daphne、supervisor、以及nginx代理websocket的安装配置。python
项目配置文件目录(wsgi.py同级)下创建立文件asgi.py,加入应用: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()
启动daphne 测试是否正常运行(成功之后退出)web
daphne -p 8001 devops.asgi:application
supervisor是由python实现的一个进程管理工具,能够确保所管理的进程一直运行,当进程一点中断supervisord会自动进行重启。django
安装步骤:服务器
#yum安装: yum install python-setuptools easy_install supervisor 或者 yum install -y epel-release yum install -y supervisor #手动安装: 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安装: pip install supervisor
生成配置文件websocket
echo_supervisord_conf > /etc/supervisord.conf
编辑/etc/supervisord.conf加入配置app
[program:daphne] directory=/opt/app/devops #项目目录 command=daphne -b 127.0.0.1 -p 8001 --proxy-headers devops.asgi:application #启动命令 autostart=true autorestart=true stdout_logfile=/tmp/websocket.log #日志 redirect_stderr=true
启动supervisorsocket
supervisord -c /etc/supervisord.conf
启动或者中止daphne工具
supervisorctl start daphne
supervisorctl stop daphne
修改nginx配置文件
#####转发配置 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; }
