于是就到“MySQL5安装目录Data ”目录里把ib_logfile0日志文件删掉，重启MySQL服务，还是提示10067错误。再去查看err文件。

可以看到，ib_logfile0的问题解决了，但是同样的问题却出在ib_logfile1上面了。于是依样画葫芦，把ib_logfile1删了，再重启MySQL服务，却发现没用。难道是还要重启系统。果真，把前面两个ib_logfile删了，重启系统就搞定了。前面的可能是因为刚开机，所以也行。实际上是需要重启系统的。这时的日志如下
101001 19:19:24 InnoDB: Log file .ib_logfile0 did not exist: new to be created

好了，现在只剩下最后一个问题了Default storage engine (InnoDB) is not available。去services.msc里面启动MySQL服务，还是出错。但是日志却是显示
InnoDB: No valid checkpoint found.
InnoDB: If this error appears when you are creating an InnoDB database,
InnoDB: the problem may be that during an earlier attempt you managed
InnoDB: to create the InnoDB data files, but log file creation failed.
InnoDB: If that is the case, please refer to
