出现如下语句：The ‘InnoDB' feature is disabled; you need MySQL built with ‘InnoDB' to have it working；
是mysql教程配置文件禁掉了这个选项！
关闭mysql数据库教程
在mysql的安装目录中找到my.ini文件
找到skip-innodb，在前面加上#号
保存，开启mysql数据库！搞定！
这也是开启Mysql数据库InnoDB功能的方法!!
启动不解决方法
090613 10:15:27 [ERROR] Default storage engine (InnoDB) is not available
090613 10:15:27 [ERROR] Aborting
090613 10:15:27 [Note] C:wwwmysqlbinmysqld-nt: Shutdown complete
估计是上次加了参数后，一直没启动起来。已经很久没用本机的MySQL了。
查了下，原来my.ini里有一句：default-storage-engine=INNODB，把默认的engine设为INNODB，而我又加了skip-innodb，怪不得启不来了。
将default-storage-engine改为MYISAM，MYSQL启动OK！
在skip-innodb下，data目录下的ibdata1,ib_logfile0,ib_logfile1这三个文件就不需要了，就可以删除。
测试了下，在没加skip-innodb时，删除了这三个文件，启动时会自动创建这三个文件，日志如下：

再删除这三个文件，加了skip-innodb后，启动日志：
