Can't shift from an empty datastructure

$worker->onWorkerStart = function() {
    global   $dns;
    $loop    = Worker::getEventLoop();
    $factory = new React\Dns\Resolver\Factory();
    $dns     = $factory->create('8.8.8.8', $loop);
};

把8.8.8.8 换成阿里云内网dns服务器地址。

如果React\Dns不太会用的话，可以用ip来连数据库，不要用域名。
