Reason one (viewed on-line):

Increase the size of the ib_logfile and forget to remove the original IB log. As a result, InnoDB found that the IB log files and configuration files on the disk were inconsistent in size during startup, roughly InnoDB boot failure.

Reason two:

MY.CNF modification error, resulting in innodb_log_file_size This parameter does not take effect.

Any operation on the InnoDB table will get this error, error 1286 (42000): Unknown table engine ' InnoDB '

Workaround:

Remove Ib_logfile restart.
