我在这里炸弹了方法，相信大家的也应该差不多。
1.使用SQL语句：
CREATE TABLE IF NOT EXISTS `PREFIX_core_directory_storage` (
`directory_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(255) NOT NULL DEFAULT '',
`path` varchar(255) NOT NULL DEFAULT '',
`upload_time` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
`parent_id` int(10) unsigned DEFAULT NULL,
PRIMARY KEY (`directory_id`),
UNIQUE KEY `IDX_DIRECTORY_PATH` (`name`, `path`),
KEY `parent_id` (`parent_id`),
CONSTRAINT `FK_DIRECTORY_PARENT_ID` FOREIGN KEY (`parent_id`)
REFERENCES `PREFIX_core_directory_storage` (`directory_id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Directory storage';
Don’t forget to write name of the table with your prefix. (’PREFIX_core_directory_storage’) 不要忘了有前缀哦。
2.手动在Magento后台更改：
Log in to the admin control panel, then:
1. Navigate to System > Configuration > Advanced > System > Storage Configuration for Media
2. Set the Media Storage option to ‘Database’ and click synchronize
Magento will generate the ‘core_directory_storage’ table for you, as well as fill it with all of your media information.
配置完成后，记得关掉哦。
正文完
