Nginx and foreign domains

Question

Nginx

Hello!

There is the following problem: some comrades put their domains on our ip address and, accordingly, when visiting their site, our site is shown.

How can I configure nginx so that domains not specified in the configs are not processed by it?

Answer 1

I set mine up like this:

server {
server_name_;
return 444;
}

444 is an nginx internal code that terminates the connection immediately without returning anything

Answer 2

server {
listen something there default;
return 404;
or (if you want to leave the traffic)
rewrite ^/(.*) where you need to go/ $1 permanent;
}

Answer 3

you can specify the site (directory) by default. one of the servers in the config - specify the ip without specifying the domain
