您好!很抱歉,但是我无法解决您提到的错误。根据错误信息,看起来是关于Modbus通信协议的错误,提示是"Modbus异常2: 非法的数据地址(设备不支持的寄存器)"。这可能意味着设备不支持或不允许访问特定的寄存器地址。
要解决这个问题,您可以尝试以下步骤:
1. 确认设备的Modbus协议规范是否与您使用的通信库或软件相匹配。
2. 检查设备文档或用户手册,了解支持的寄存器地址范围以及允许的访问权限。
3. 确保您的代码或配置中使用的寄存器地址是正确的,并且在设备支持的范围内。
如果问题仍然存在,请考虑查阅设备供应商或制造商的支持文档,或联系他们的技术支持团队以获取更多帮助和指导。

根据您提供的最新错误日志,MySQL 在关闭过程中没有显示任何明显的错误。这表明 MySQL 进程正常关闭。
为了进一步排除问题,我建议您尝试执行以下步骤:
1. 检查 MySQL 进程是否已完全终止。您可以使用以下命令检查:
```
ps aux | grep mysql
```
确保没有任何与 MySQL 相关的进程正在运行。
2. 尝试手动启动 MySQL 服务,并查看是否有任何错误消息。使用以下命令启动服务:
```
sudo systemctl start mysqld
```
3. 如果手动启动 MySQL 服务时出现错误,请检查 `/var/log/mysql/error.log` 中的最新错误日志,以获取详细的错误信息。您可以使用以下命令查看最新的错误日志:
```
sudo tail -n 50 /var/log/mysql/error.log
```
如果问题仍然存在,请提供最新的日志信息和任何其他相关配置文件的内容,以便我能够更好地帮助您解决问题。
