Question

我正在尝试使用daphne和nginx部署需要http和websocket连接的Django应用程序。 nginx和daphne之间的连接是使用Linux套接字建立的。当nginx收到请求时，daphne将退出，错误为“地址已在使用中”

我确保同时运行nginx和daphne的两个用户都具有对sock文件的读写访问权限

nginx conf

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {worker_connections 1024;}
http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;}
     access_log  /var/log/nginx/access.log  main;
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;
    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;
    upstream websocket{server unix:/run/daphne/bot.sock;}
    include /etc/nginx/conf.d/*.conf;
    server {
        listen 80;
        server_name 10.xx.xx.65;
        location /static/js { alias /var/botstatic/js;}
        location /static/img { alias /var/botstatic/img;}
        location /static/css { alias /var/botstatic/css;}
        location /static/webfonts {alias /var/botstatic/webfonts;}          
        location / {
        proxy_pass http://websocket;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;}
}

期望nginx和daphne通过Linux套接字连接实际结果nginx给出502 Bad Gateway错误，daphne退出并显示此错误

CRITICAL Listen failure: Couldn't listen on any:b'/run/daphne/bot.sock': [Errno 98] Address already in use.
