The basic difference is : MyISAM type of advanced processing transactions, which do not support, and support for InnoDB type. MyISAM table type to emphasize that performance, which performs several times faster than InnoDB type, but does not provide transaction support, and InnoDB provides transaction support and foreign keys and other advanced database features.
Why should I change the default engine, it is actually quite simple, Mysql default MyISAM engine I'm using, but MyISAM does not support transaction processing, so I need to replace its engine.

1. Check the Mysql storage engine: The mysql>show engines InnoDB | YES, the description for this Mysql database server supports InnoDB engine.
2. Set the default InnoDB engine: configuration file in my.inithe [mysqld] below was addeddefault-storage-engine=INNODB
3. Restart Mysql server
4. Log Mysql database, mysql>show engines if there is InnoDB |DEFAULT, then set InnoDB as the default engine success.
