The service command supports only basic LSB actions

Mysql命令报错The service command supports only basic LSB actions(start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.

翻译：服务命令只支持基本的LSB操作(启动、停止、重启、尝试重启、重载、强制重载、状态)。对于其他操作，请尝试使用systemctl。
此原因是由于mysql版本问题，应采用 systemctl命令
使用如下命令操作mysql：
systemctl restart mysqld.service
systemctl start mysqld.service
systemctl stop mysqld.service
