netstat -aon

任务管理器找到相应的3306的pid 直接杀死；

mysql error:Access denied for user 'root'@'localhost' (using password: YES)

   ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;   #修改加密规则 

   ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';   #更新一下用户的密码 

3. 刷新权限并重置密码

   FLUSH PRIVILEGES;   #刷新权限 

再重置下密码：alter user 'root'@'localhost' identified by '111111';

现在再次打开Navicat Premium 12连接MySQL问题数据库就会发现可以连接成功了
