默认apache2ctl status访问的是http://localhost:80/server_status
所以得搞定default这个站点，放歌html就可以了。
在default的配置里加入下面的配置：
<Location /server-status>
SetHandler server-status
Order Deny,Allow
Deny from all
Allow from localhost
</Location>
默认的HTMl放个跳转挺好的：<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<meta http-equiv="refresh" content="1;url=http://example.com">
<script type="text/javascript">
window.location.href = "http://example.com"
</script>
<title>Page Redirection</title>
</head>
<body>
<!-- Note: don't tell people to `click` the link, just tell them that it is a link. -->
If you are not redirected automatically, follow the <a href='http://example.com'>link to example</a>
</body>
</html>
