解决Operating system error number 87 in a file operation
windows10,环境下，小皮面板（phpstudy）客户端里，安装mysql各个版本数据库都无法启动。
报错日志如下：
2021-05-30T12:19:04.744352Z 0 [ERROR] InnoDB: Operating system error number 87 in a file operation.
2021-05-30T12:19:04.744821Z 0 [ERROR] InnoDB: File .\ib_logfile0: 'aio read' returned OS error 187. Cannot continue operation
2021-05-30T12:19:04.745223Z 0 [ERROR] InnoDB: Cannot continue operation.
解决：
在mysql的配置文件里加上“innodb_flush_method=normal”，如下：
[mysqld]
innodb_flush_method=normal
port=3306
