我最近升级了XAMPP，并且（可能很愚蠢地）只是将旧的mysql/data文件夹复制到新安装中。我不确定之前运行的是什么版本的MySQL，但它可能是5.1。新版本是5.6。每当我启动MySQL时，我都会收到此错误：
2014-11-05 23:31:04 8784 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace db_name/table_name uses space ID: 2 at filepath: .\db_name\table_name.ibd. Cannot open tablespace mysql/innodb_index_stats which uses space ID: 2 at filepath: .\mysql\innodb_index_stats.ibd
InnoDB: Error: could not open single-table tablespace file .\mysql\innodb_index_stats.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.
我从this question和其他人那里知道删除ibdata1和ib_logfile0文件暂时解决了这个问题，但每次启动XAMPP / MySQL时我都需要这样做。有没有办法永久解决这个问题？
