直接在 http 模块下面添加 stream模块即可

stream{
    upstream mysql{
        server 192.168.51.115:3306 weight=1;
        server 192.168.51.116:3306 weight=1;
    }
        
    server{
        listen 3308;
        proxy_pass mysql;
    }

    upstream mq{
        server 192.168.51.115:15672 weight=1;
        server 192.168.51.117:15672 weight=1;
    }
        
    server{
        listen 15671;
        proxy_pass mq;
    }
}
