突然收到MySQL报警,从库的数据库挂了,一直在不停的重启,打开错误日志,发现有张表坏了。innodb表损坏不能通过repair table 等修复myisam的命令操作。现在记录下解决过程,下次遇到就不会这么手忙脚乱了。

处理过程:
 一遇到报警之后,直接打开错误日志,里面的信息:

InnoDB: Database page corruption on disk or a failed
InnoDB: file read of page 30506.
InnoDB: You may have to recover from a backup.
130509 20:33:48 InnoDB: Page dump in ascii and hex (16384 bytes):
##很多十六进制的代码
……
……
InnoDB: End of page dump

InnoDB: You may have to recover from a backup.
InnoDB: It is also possible that your operating
InnoDB: system has corrupted its own file cache
InnoDB: and rebooting your computer removes the
InnoDB: error.
InnoDB: If the corrupt page is an index page
InnoDB: you can also try to fix the corruption
InnoDB: by dumping, dropping, and reimporting
InnoDB: the corrupt table. You can use CHECK
InnoDB: TABLE to scan your table for corruption.
