如何使用mysql配置gammu smsd

我正在尝试启动gammu sms服务，当我使用简单存档运行它时，它运行良好，但当我尝试使用mysql数据库运行它时，它显示以下错误：

错误代码：2002，错误：无法通过套接字“/var/run/mysqld/mysqld.sock”连接到本地MySQL服务器（2） 重新启动gammu sms，显示以下消息：

有什么办法帮我吗？非常感谢

您的用户没有权限，您以

user2@Lubuntu18

尝试以root用户身份启动gammu smsd，或向user2添加权限

dialout

sudo gammu-smsd -d --user gammu --group dialout

是的，我将我的用户添加到组拨号中，一切正常。谢谢
