在webman 中如何单独启动worker 做redis 队列消费

<?php

require __DIR__ . '/../../../vendor/autoload.php';

use Workerman\Worker;
use Workerman\RedisQueue\Client as QueueClient;

$worker = new Worker();
$worker->name = 'QueueWorker';
$worker->count = 8;
$worker->onWorkerStart = function () {

    $apiHost = 'http://www.baidu.com';
    $queueClient = new QueueClient('redis://127.0.0.1:6379',['auth' => '123','db' => 0,'retry_seconds' => 2,'max_attempts' => 2]);

    //物联网
    $queueClient->subscribe('iot-queue', function($data){

    });
};

Worker::runAll();
