WAMP mysql 无法启动的解决方法

WAMP mysql 无法启动，手动启动wampmysqld进程报1067的错误。

通过查看mysql log，发现

2013-11-26 19:04:11 5068 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace usernet/message uses space ID: 9 at filepath: .\usernet\message.ibd. Cannot open tablespace usernet/messages which uses space ID: 9 at filepath:
.\usernet\messages.ibd

2013-11-26 19:04:11 13b4 InnoDB: Operating system error number 997 in a file operation.

InnoDB: Some operating system error numbers are described at

InnoDB: http://dev.mysql.com/doc/refman/5.6/en/operating-system-error-codes.html
InnoDB: Error: could not open single-table tablespace file .\usernet\messages.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.

由于数据不重要，我选择删除 messages.ibd

重启wamp server 正常启动
