could not open single-table tablespace file

window下免安装版mysql启动报如下错误

2014-02-11 16:20:27 8984 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace minblog/tal_advertisement uses space ID: 2 at filepath: .\minblog\tal_advertisement.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

解决方法

Move (DON'T DELETE) those files, into another folder:

innodb_index_stats.frm
innodb_table_stats.frm
slave_master_info.frm
slave_relay_log_info.frm
slave_worker_info.frm
and .ibd files with the same filename:

innodb_index_stats.ibd
innodb_table_stats.ibd
slave_master_info.ibd
slave_relay_log_info.ibd
slave_worker_info.ibd
Try start MySQL.
