在Linux下启动两个时报错

问题详细描述

在Linux下启动两个时报错
百度搜了一下加入$pidFile

  Worker::$pidFile = app()->getRootPath().'MyCrontab.pid';

也还是不行

程序代码

<?php
namespace app\YourApp\liunx;

use think\admin\Command;
use think\console\Input;
use think\console\Output;
use think\console\input\Argument;
use think\console\input\Option;

use Workerman\Connection\AsyncTcpConnection;
use Workerman\Worker;

use think\facade\Cache;

/**
 * Worker 命令行类

class Ceshi extends Command
{

    public function configure()
    {

        $this->setName('Ceshi')
        ->addArgument('action', Argument::OPTIONAL, "start|stop|restart|reload|status|connections|OK", 'start')
      ->addOption('mode', 'm', Option::VALUE_OPTIONAL, 'Run the workerman server in daemon mode.')
      ->setDescription('the workerman command');

    }
    public function execute(Input $input, Output $output)
    {

      $action= $input->getArgument('action');
      $mode = $input->getOption('mode');

      Worker::$pidFile = app()->getRootPath().'MyCrontab.pid';
    // 重新构造命令行参数,以便兼容workerman的命令
    global $argv;

    $argv = [];

    array_unshift($argv, 'think', $action);
    if ($mode == 'd') {
      $argv[] = '-d';
    } else if ($mode == 'g') {
      $argv[] = '-g';
    }
    if ('OK' == $action) {

        return "";
  }
  if ('start' == $action) {

    $this->start(1, 0);
}

    }

    /**

     * @return void
     */
    public function start($bot1,$bot)
    {

        $worker = new Worker();

$worker->onWorkerStart = function()use($bot1,$bot)
{

       $conC_url="ws://xxx";
       $con_url="ws://xxx";

       //配置
$conC = new AsyncTcpConnection($conC_url);$conC->transport = 'ssl';
// // 心跳定时器
Timer::add(20, function() use ($conC){$conC->send("ping");});
                // 远程websocket服务器发来消息时
$conC->onMessage = function($connection, $data){
  //实盘
  $this->output->writeln(date('Y-m-d H:i:s',time()). "消息 ".$data." ");
};
// 连接上发生错误时，一般是连接远程websocket服务器失败错误
$conC->onError = function($connection, $code, $msg){};
// 当连接远程websocket服务器的连接断开时// 如果连接断开20秒后自动重连
$conC->onClose = function($connection){$this->output->writeln(date('Y-m-d H:i:s',time())." 重连"); $connection->reconnect(5);};
$conC->connect();

};
Worker::runAll();

    }

    }

报错信息

Workerman[think] start in DEBUG mode
Workerman[think] already running

触发报错的步骤

think Startws1 start 正常
think Startws2 start 不正常
