2017-09-30 08:13:02 2816 [Note] InnoDB: Reading tablespace information from the .ibd files...
2017-09-30 08:13:02 2816 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace mysql/innodb_index_stats uses space ID: 2 at filepath: .\mysql\innodb_index_stats.ibd. Cannot open tablespace rsgl_jl/jhsoft_xz_qcb which uses space ID: 2 at filepath: .\rsgl_jl\jhsoft_xz_qcb.ibd
InnoDB: Error: could not open single-table tablespace file .\rsgl_jl\jhsoft_xz_qcb.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.

1、在MY.INI文件中的[mysqld]中增加一行tmpdir="D:/MySQL/data/"修改后，还是启动不了或者能启动但关机后又出现同样问题，接着我做了第二步，重启正常。2、删除DATA目录下除数据库文件夹外的其他文件，重启mysql，问题解决。
