asgi配置环境变量

需要添加

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myblogsite.settings')

from django.core.asgi import get_asgi_application
# import django
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myblogsite.settings')
django_asgi_app = get_asgi_application()
from channels.auth import AuthMiddlewareStack

from channels.routing import ProtocolTypeRouter,URLRouter#channels的路由
import webchat.routing

# django.setup()
application=ProtocolTypeRouter(
    {
        "http":get_asgi_application(),
        #添加http协议
        "websocket": AuthMiddlewareStack(
            URLRouter(
                webchat.routing.websocket_urlpatterns
                #聊天app
            )
        ),
        #路由配置
    }
)

daphne运行asgi

指定所有ip可以访问，开放8001端口

daphne -b 0.0.0.0 -p 8001 myproject.asgi:application

install supervisor

安装supervisor

yum install -y supervisor

生成配置文件

echo_supervisord_conf > /etc/supervisord.conf

编辑配置文件
[include]
files = supervisord.d/*.ini
表示配置文件读取supervisord.d目录下所有后缀为.ini的文件。
创建配置目录，并创建配置文件
mkdir /etc/supervisord.d/
vi /etc/supervisord.d/asgi.ini
编辑

[fcgi-program:asgi]
# TCP socket used by Nginx backend upstream
socket=tcp://localhost:8001

# Directory where your site's project files are located django项目路径
directory=/data/wwwroot/myblog_project/myblogsite

# Each process needs to have a separate socket file, so we use process_num
# Make sure to update "mysite.asgi" to match your project name 虚拟环境 相对路径下的asgi
command=/data/pyweb/bin/daphne -u /run/daphne/daphne%(process_num)d.sock --fd 0 --access-log - --proxy-headers myblogsite.asgi:application

# Number of processes to startup, roughly the number of CPUs you have
numprocs=4

# Give each process a unique name so they can be told apart
process_name=asgi%(process_num)d

# Automatically start and recover processes
autostart=true
autorestart=true

# Choose where you want your log to go
stdout_logfile=/data/asgilog/asgi.log
redirect_stderr=true

创建文件夹生成daphe的sock文件

$ sudo mkdir /run/daphne/

赋予权限

$ chmod +x /run/daphe

运行

$ supervisord -c /etc/supervisord.conf

ok! 没问题

查看日志

nginx转发websokcet

map

map $http_upgrade $connection_upgrade{
    default upgrade;
    '' close;
    }

处理websocket的请求，发送的请求是：ws://yongma16.xyz/ws/webchat/DjangoVue/
代理配置

location /ws/{
        proxy_pass http://127.0.0.1:8001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
}

发送请求成功！

部署成功！
