Typecho 安装的默认后台路径是 example.com/admin/ 为了提高安全性，我们可以让后台地址以 example.com/xxxxx/ 的方式访问，其中xxxxx 是你自定义的路径。

首先登陆主机后台，将Typecho程序根目录中的后台文件夹"admin"重命名，名字即为你想自定义的地址名，例如：将"admin"改为"xxxxx"。

然后在根目录找到 "config.inc.php" 的文件，大概在13行的位置找到以下代码

// admin directory (relative path)

define('__TYPECHO_ADMIN_DIR__', '/admin/');

将代码中admin改为xxxxx。这样我们的Typecho程序网站的后台就改成：域名example.com/xxxxx/了。

做完上面的操作后，你可以在网站根目录新建一个admin文件夹，然后里面放一个仿 FBI Warning 的index.html 页面对非法访问进行警告。

复制下面的源码到新建的 index.html 保存即可。
