<?php

    public function onWorkerStart(): void
    {
        // 每20秒执行一次
        new Crontab('*/20 * * * * *', function(){
            echo date('Y-m-d H:i:s')."\n";
            shell_exec("/usr/bin/env php /path/to/webman/start.php status");
            $config = config('server');
            if (file_exists($config['status_file'])) {
                $status_content = file_get_contents($config['status_file']);
                echo $status_content,PHP_EOL;
            }
