默认的dedecms安装完毕之后访问后面会跟上一个index.html，觉得这个不好，怎么去掉呢。我们打开网站根目录的index.php文件

<?php
/**
 * @version        $Id: index.php 1 9:23 2010-11-11 tianya $
 * @package        DedeCMS.Site

 */
if(!file_exists(dirname(__FILE__).'/data/common.inc.php'))
{
    header('Location:install/index.php');
    exit();
}
//自动生成HTML版
if(isset($_GET['upcache']) || !file_exists('index.html'))
{
    require_once (dirname(__FILE__) . "/include/common.inc.php");
    require_once DEDEINC."/arc.partview.class.php";
    $GLOBALS['_arclistEnv'] = 'index';
    $row = $dsql->GetOne("Select * From `#@__homepageset`");
    $row['templet'] = MfTemplet($row['templet']);
    $pv = new PartView();
    $pv->SetTemplet($cfg_basedir . $cfg_templets_dir . "/" . $row['templet']);
    $row['showmod'] = isset($row['showmod'])? $row['showmod'] : 0;
    if ($row['showmod'] == 1)
    {
        $pv->SaveToHtml(dirname(__FILE__).'/index.html');
        include(dirname(__FILE__).'/index.html');
        exit();
    } else { 
        $pv->Display();
        exit();
    }
}
else
{
  include(dirname(__FILE__).'/index.html');//主要是这行代码
  exit(); //主要是这行代码
}
?>

把上面的代码覆盖index.php文件就可以了。没有效果的话清除缓存在看看
