Nginx WebSocket 反向代理与长连接优化

Nginx WebSocket 反向代理与长连接优化upstream ws_backend {

server 127.0.0.1:7002;

keepalive 64;

}

server {

listen 80;

server_name example.com;

location /ws/ {

proxy_pass http://ws_backend;

proxy_http_version 1.1;

proxy_set_header Upgrade $http_upgrade;

proxy_set_header Connection "upgrade";

proxy_read_timeout 600s;

proxy_send_timeout 600s;

}

}

总结为 WebSocket 设置 Upgrade/Connection 并延长超时，配合 upstream keepalive，可显著提升长连接稳定性。
