Magento安装抱怨InnoDB可用时丢失

文件的第59行

app/pre/core/Mage/Install/Model/Installer/Db/Mysql4.php

更换：

public function supportEngine(){    $variables  = $this->_getConnection()        ->fetchPairs('SHOW VARIABLES');    return (!isset($variables['have_innodb']) || $variables['have_innodb'] != 'YES') ? false : true;}

有了这个：

public function supportEngine(){    $variables  = $this->_getConnection()        ->fetchPairs('SHOW ENGINES');    return (isset($variables['InnoDB']) && $variables['InnoDB'] != 'NO');}
