2. 配置，保持连接配置

tcp {
    timeout 1d;
    proxy_read_timeout 10d;
    proxy_send_timeout 10d;
    proxy_connect_timeout 30;

    upstream tcpend {
        server 172.21.13.32:8999;
        check interval=60000 rise=2 fall=5 timeout=10000 type=tcp;
    }

    server {
        server_name  172.21.23.6;
        listen 172.21.23.6:8999;
        proxy_pass tcpend;
        so_keepalive on;
        tcp_nodelay on;
    }
}

 

3. 查看状态

location /status {
             tcp_check_status;
        }
