1.首页新建一个文本文件命名为 404.php，然后用文本编辑器打开，填入以下代码，并保存；

<?php
define('CURSCRIPT', '404');
require './source/class/class_core.php';
C::app()->init();
$navtitle = "404提示"; // 这里修改404页面标题
include template('common/404'); // 这里是你的404页面模版
?>

复制代码

将$navtitle = "404提示"这行代码中的“404提示”修改为你的404页面的标题，保存之后将404.php上传到你网站的根目录，

2.接下来用编辑器打开你的404的html文件（后缀为.html或者.htm），去掉head，body标签，只留下<body>与</body>中间的那段代码,其他全去掉

然后在最上面一行加上{template common/header}，在最下面一行加上{template common/footer}，保存

3.然后上传到你的服务器上的template\default\common目录里，如果你不是用的默认模板，记得将default改成你模板目录名，

4.最后，apache修改服务器配置文件上的404页面声明，也就是把 ErrorDocument 404 /404.html改成ErrorDocument 404 /404.php，不同服务器修改教程大家自行去网上找，然后你就访问一个你网站没有的路径，比如在你的域名后随便打几个字母，如http://bbs.itqu.net/errorpage就可以看到效果

最后再用HTTP返回码查询工具检测一下HTTP状态，这里成功检测出状态码为404

--------------------------------------------- 华丽分割线 ---------------------------------------------------

如果是nginx,在配置文件里可以看到

#ERROR-PAGE-START 错误页配置，可以注释、删除或修改
error_page 404 /404.html;
error_page 502 /502.html;
#ERROR-PAGE-END

复制代码

就直接在根目录放一个404.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>很抱歉，网页不存在！</title>
<style type="text/css">

margin:0;

font-family: "微软雅黑", Arial, "Trebuchet MS", Helvetica, Verdana ;
}
h1{font-size:44px; color:#0188DE; padding:20px 0px 10px 0px;}
h2{color:#0188DE; font-size:16px; padding:10px 0px 40px 0px;}
#page{width:910px; padding:20px 20px 40px 20px; margin-top:80px;}
.button{width:180px; height:28px; margin-left:0px; margin-top:10px; background:#009CFF; border-bottom:4px solid #0188DE; text-align:center;}
.button a{width:180px; height:28px; display:block; font-size:14px; color:#fff; }
.button a:hover{ background:#5BBFFF;}
</style>
</head>
<body>
<div id="page" style="border-style:dashed;border-color:#e4e4e4;line-height:30px;background:url(sorry.png) no-repeat right;">
<h1>网页不存在，即将跳转新网址</h1>
<h2>The website is moving. It is about to jump to the new website. </h2>
<meta http-equiv="refresh" content="1;url=http://bbs.itqu.net">
<font color="#666666">若网页未能自动跳转新网址，请点击下面按钮进行跳转！</font><br /><br />
<div class="button">
<a href="http://bbs.itqu.net" title="进入新网址">进入新网址</a>
</div>
</div>
</body>
</html>

复制代码

上面代码可以在访问不到的时候自动跳转首页！
