我最近重新安装了 XAMPP 以获得 PHP5.5
执行此操作时，我创建了一个新数据库，通过 phpMyAdmin 创建的 SQL 导出导入它。（它是一个实时数据库的副本，允许我在本地主机上进行开发）。
安装并重新启动 PC 后，一切正常。
在一天结束时，我关闭并离开了。当我下次打开电脑时。我收到 MySQL 关闭意外错误。认为它可能是我重新安装的新安装。重新安装后重新启动PC后，一切正常。所以我重新导入数据库，一整天都没有问题。
但是我今天又回来了，错误又回来了。任何人都知道是什么导致了错误？文件权限似乎没问题，有问题的文件（见日志）说所有用户都有写/读/等权限。

InnoDB: Error: could not open single-table tablespace file .\testserver\tbl_users.ibd
InnoDB: We do not continue the crash recovery, because the table may become
InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.
InnoDB: To fix the problem and start mysqld:
InnoDB: 1) If there is a permission problem in the file and mysqld cannot
InnoDB: open the file, you should modify the permissions.
InnoDB: 2) If the table is not needed, or you can restore it from a backup,
InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
InnoDB: crash recovery and ignore that table.
InnoDB: 3) If the file system or the disk is broken, and you cannot remove
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
InnoDB: and force InnoDB to continue crash recovery here.
