我最近很多时候都收到了这个错误。我意识到错误是因为当我关闭计算机时忘记转向mysql。我试图删除数据文件夹中的ibdata1，它不适用于这种情况。以下是我的错误日志。

2016-08-15 12:11:33 6984 [Note] InnoDB: Reading tablespace information from the .ibd files...
2016-08-15 12:11:36 6984 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace drupaltest/variable uses space ID: 31 at filepath: .\drupaltest\variable.ibd. Cannot open tablespace livestream/tbl_user which uses space ID: 31 at filepath: .\livestream\tbl_user.ibd
InnoDB: Error: could not open single-table tablespace file .\livestream\tbl_user.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
