如果首页中有index.html不利于SEO，蜘蛛用主域名跟踪到你网站的时候结果多了个index.html，结果导致分散了权重 

解决方法：将根目录下的index.php文件更改为：

<?php

if(!file_exists(dirname(__FILE__).'/data/common.inc.php'))

{

     header('Location:install/index.php');

     exit();

}

require_once (dirname(__FILE__) . "/include/common.inc.php");

require_once DEDEINC."/arc.partview.class.php";

$GLOBALS['_arclistEnv'] = 'index';

$row = $dsql->GetOne("Select * From `dede_homepageset`");

$row['templet'] = MfTemplet($row['templet']);

$pv = new PartView();

$pv->SetTemplet($cfg_basedir . $cfg_templets_dir . "/" . $row['templet']);

$pv->Display();

?>
