This may be due to a blocked port, missing dependencies,
improper privileges, a crash, or a shutdown by another method.

解决方法：
- 打开注册表编辑器
- 导航到：计算机\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MySQL
- 双击 ImagePath ，将数值数据修改为xampp下mysql下bin下文件的地址，例如：d:\xampp\mysql\bin\mysqld.exe --defaults-file=d:\xampp\mysql\bin\my.ini mysql
- 设置完毕后，点击Start，启动成功
