如何禁用通过 IP 地址直接访问网站 [英] how to disable direct access to a web site by ip address

问题描述

我在 VPS 上有一个网站.

I have a website on a VPS.

我遇到的问题是，当我输入服务器的 IP 时，它会链接到网站.
即使输入mail.domain.com，它也会做同样的事情.

The issue I am having is that when I enter the IP of the server, it links to the website.
Even when entering mail.domain.com, it does the same thing.

如何禁用它，以便访问者收到消息或被定向到域?

How do I disable that, so a visitor would get a message or be directed to the domain?

我尝试禁用 IP 并在 Cloudflare 上邮寄记录，但没有奏效.

I tried disabling the IP and mail a record on cloud flare but it didn't work.

我的设置是:

VPS on Linux Debian 
Nginx
no control panel just command line
Cloudflare
DNS setup with BIND

推荐答案

server {
    listen      80 default_server;
    listen      [::]:80 default_server;
    server_name "";
    return      444;
}

您需要指定default_server 参数，以便所有不可用的服务器请求都转到这个服务器块，这会引发444 错误.

You need to specify default_server parameter so that all non available server requests goes to this server block which throws 444 error.

444:连接关闭，没有响应
