Magento SIDhttpd.conf Can Override php.ini »关于Magento一次安装，多处使用的构想
WordPress可以一次安装，多处使用，Magento当然更有理由这么做了。

Magento 强大的功能之一就是run multi websites，Magento内置了多站点运行的功能。我援引从WordPress安装管理探索出的经验，觉得即使Magento内置multi websites功能，各站点还是不要使用同一个document root为好，还是以一主多副软连接的方式为宜。

只是，我还是没有找到在后台隔离各站点的办法（假设它们由不同的web manager来经营）。我也无法控制上传目录，所有上传得文件都是存放在主域名的document root/{magento installatin path}/media下。

好在magento子目录安装，根目录显示还是做得到的。如将magento放置在document root/magento下，但前台url不出现magento，具体的做法是

1. 把index.php和.htaccess移到document root，其他文件都放置在document root/magento子目录

2. 把index.php修改成

exit;
}

$mageFilename = ‘magento/app/Mage.php’;

if (!file_exists($mageFilename)) {

umask(0);

3. 把.htaccess修改成：
