server {
    listen 80;
    server_name ws.example.com;

    location /ws/ {
        proxy_pass http://backend_server;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        
         重要超时配置
        proxy_read_timeout 86400s;
        proxy_send_timeout 86400s;
    }
}

upstream websocket_cluster {
    ip_hash;   保持会话粘性
    server 10.0.0.1:8080;
    server 10.0.0.2:8080;
}

server {
    location /wsapp/ {
        proxy_pass http://websocket_cluster;
         其他配置同上...
    }
}

server {
    listen 443 ssl;
    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;
    
    location /wss/ {
        proxy_pass http://secure_backend;
         WebSocket头配置...
    }
}

 在http块中添加
map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}
