  • mysq 因断电而导致的错误

    问题来源:

    昨天断电,而我没有保存,导致出现以下问题:

    2015-10-12 10:48:10 7300 [Note] Plugin 'FEDERATED' is disabled.
    2015-10-12 10:48:10 2080 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.

    2015-10-12 10:48:10 7300 [Note] InnoDB: Memory barrier is not used
    2015-10-12 10:48:10 7300 [Note] InnoDB: Compressed tables use zlib 1.2.3

    2015-10-12 10:48:10 7300 [Note] InnoDB: Initializing buffer pool, size = 16.0M
    2015-10-12 10:48:10 7300 [Note] InnoDB: Completed initialization of buffer pool
    2015-10-12 10:48:10 7300 [Note] InnoDB: Restoring page 0 of tablespace 0
    2015-10-12 10:48:10 7300 [Warning] InnoDB: Doublewrite does not have page_no=0 of space: 0
    2015-10-12 10:48:10 7300 [ERROR] InnoDB: space header page consists of zero bytes in data file C:xamppmysqldataibdata1
    2015-10-12 10:48:10 7300 [ERROR] InnoDB: Could not open or create the system tablespace. If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!
    2015-10-12 10:48:10 7300 [ERROR] Plugin 'InnoDB' init function returned error.
    2015-10-12 10:48:10 7300 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
    2015-10-12 10:48:10 7300 [ERROR] Unknown/unsupported storage engine: InnoDB
    2015-10-12 10:48:10 7300 [ERROR] Aborting

    解决办法:

    错误日志里已经告诉你了: C:xamppmysqldataibdata1 把这个下面的 ibdata1 和 ib_logfle0 ib_lofile1 删掉。

    如果,数据库损坏了,在这个目录下,把数据库文件删掉删掉,然后重新建立即可。

    以上方法 同样适用于 windows 和linux
