启动WAMP Server的时候报例如以下的错误：
140618 23:12:32 [Note] Plugin 'FEDERATED' is disabled. 140618 23:12:32 InnoDB: The InnoDB memory heap is disabled 140618 23:12:32 InnoDB: Mutexes and rw_locks use Windows interlocked functions 140618 23:12:32 InnoDB: Compressed tables use zlib 1.2.3 140618 23:12:32 InnoDB: Initializing buffer pool, size = 128.0M 140618 23:12:32 InnoDB: Completed initialization of buffer pool InnoDB: Error: log file .\ib_logfile0 is of different size 0 10485760 bytes InnoDB: than specified in the .cnf file 0 5242880 bytes! 140618 23:12:32 [ERROR] Plugin 'InnoDB' init function returned error. 140618 23:12:32 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 140618 23:12:32 [ERROR] Unknown/unsupported storage engine: InnoDB 140618 23:12:32 [ERROR] Aborting请注意这几行:
InnoDB: Error: log file .\ib_logfile0 is of different size 0 10485760 bytes InnoDB: than specified in the .cnf file 0 5242880 bytes!你能够计算一下10485760的大小，10485760/1024/1024=10，改动my.ini,
innodb_log_file_size = 10M要看mysql的日志，请进行例如以下操作：
InnoDB: Error: log file .\ib_logfile0 is of different size 0 10485760 bytes
