Django channles线上部署（腾讯云）

基本架构：

​ nginx >> supervisor >> Daphne >> websocket

配置

• 安装daphne

  #pip install channels
  
  #安装结束后会在当前虚拟环境下产生daphne
  

• 配置django asgi

  配置asgi.py文件（假设你已经做好了websocket的路由转向），如果不增加以下这两行，就会报错
  
  ###########
  import django 
  
  ...
  
  django.setup()
  ...
  

• 测试daphne

  $(pwd)\venv\daphne -p 8001 -b 0.0.0.0 <your_project_name>.asgi:application
  
  
  #以上测试通过后(向该地址+路由发送ws数据)，如果退出终端，该进程任务将会结束
  

• 安装supervisor持续进程任务

  #centos
  yum install supervisor
  
  #ubunto :
  apt-get install supervisor
  
  #pip 
  pip install supervisor
  

• 编写配置文件

  #/etc/supervisord.conf, 这是主配置文件，我们不改它
  
  #/etc/supervisord.d/self_config.ini    新增这个文件，编写配置内容，文件名称随意
  
  [program:daphne]
  directory=/www/personMapProject  #项目目录
  command=/www/personMapProject/venv/bin/daphne -b 127.0.0.1 -p 8889 personMapProject.asgi:application   #绑定端口 
  autostart=true
  autorestart=true
  stdout_logfile=/www/personMapProject/websocket.log #日志路径
  redirect_stderr=true
  
  #以上内容不要有注释
  

• 使用supervisor

  supervisorctl status        //查看所有进程的状态
  supervisorctl stop es       //停止es
  supervisorctl start es      //启动es
  supervisorctl restart       //重启es
  supervisorctl update        //配置文件修改后使用该命令加载新的配置
  supervisorctl reload        //重新启动配置中的所有程序,自动加载子配置文件
  

• 配置nginx

  user  root;
  worker_processes  2;
  events {
      worker_connections  1024;
  }
  
  http {
      include       mime.types;
      default_type  application/octet-stream;
      keepalive_timeout  65;
      gzip on;
      
      upstream channels-backend {
          server localhost:8889;
      }
      
      server {
  		    listen   80;
  
          location / {
              include uwsgi_params;
              uwsgi_pass 127.0.0.1:8888;
              uwsgi_send_timeout 600;
  
          }
          location /static {
              alias /www/personMapProject/collect_static/;
          }
          location /media {
              alias /www/personMapProject/media/;
          }
  
          location = /50x.html {
              root   html;
          }
          location /ws {
              proxy_pass http://channels-backend;
  
              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;
          }
      }
  }
