MYSQL服务无法启动：InnoDB: .\ibdata1 can't be opened in read-write mode，innodbibdata1
今天在那做实验倒腾mysql数据库，后来发现服务无法启动，查看日志报错如下：
2015-01-07 17:48:54 9136 [ERROR] InnoDB: .\ibdata1 can't be opened in read-write mode
2015-01-07 17:48:54 9136 [ERROR] InnoDB: The system tablespace must be writable!
2015-01-07 17:48:54 9136 [ERROR] Plugin 'InnoDB' init function returned error.
2015-01-07 17:48:54 9136 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
2015-01-07 17:48:54 9136 [ERROR] Unknown/unsupported storage engine: InnoDB
2015-01-07 17:48:54 9136 [ERROR] Aborting
解决方法：
1、打开任务管理器终止mysqld进程；
2、打开mysql安装目录的data文件夹，删除以下2个文件：
ib_logfile0和ib_logfile1
3、重新启动mysql
