Magento数据库访问配置

我相信这是一个非常新的问题，我对magento和PHP都是新手。我在连接我的megento安装到MySQL实例时遇到了困难。我已经安装了Zend软件包，并尝试在''Zend''magento''app''etc目录下编辑config.xml和local.xml，如下所示

        <connection>//config.xml
            <host>localhost:4928</host>
            <username>root</username>
            <password>test</password>
            <dbname>store</dbname>
            <model>mysql4</model>
            <initStatements>SET NAMES utf8</initStatements>
            <type>pdo_mysql</type>
            <active>0</active>
        </connection>
                <connection> //local.xml
                    <host><![CDATA[localhost:4928]]></host>
                    <username><![CDATA[root]]></username>
                    <password><![CDATA[test]]></password>
                    <dbname><![CDATA[store]]></dbname>
                    <active>1</active>
                </connection>

在这样做之后，我得到了以下错误

Warning: include(Mage'Catalog'Model'Attribute'Backend'Customlayoutupdate.php) [function.include]: failed to open stream: No such file or directory  in E:'servers'zend'magento'app'code'core'Mage'Core'functions.php on line 70
