magento 支持mysql5.6安装

magento 需要pdo_mysql, innodb支持, 假如你安装时提示innodb存储引擎不可用, 可以按以下方式修改:
\app\code\core\Mage\Install\Model\Installer\Db\Mysql4.php supportEngine 方法:

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

修改为:

public function supportEngine() 
{ 
    $variables  = $this->_getConnection() 
        ->fetchPairs('SHOW VARIABLES'); 
    $ret = (!isset($variables['have_innodb']) || $variables['have_innodb'] != 'YES') ? false : true; 
    if(version_compare($this->getVersion(),'5.5.5','>=')){ 
        $ret = true; 
    } 
    return $ret; 
}
