抛异常的地方：
raise MaxRetryError(_pool, url, error or ResponseError(cause))
urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host=‘192.168.0.105’, port=4444): Max retries exceeded with url: /wd/hub/session (Caused by NewConnectionError(’<urllib3.connection.HTTPConnection object at 0x10aff7a50>: Failed to establish a new connection: [Errno 61] Connection refused’))
CentOS环境已经检查过了，应该是没问题，麻烦老师解答下，在这里卡住了，头疼…
