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();
?>
