This article mainly introduces the setting of Nginx to prohibit access to unbound domain names. It has certain reference value. Now I share it with you. Friends in need can refer to it.
By default, Nginx allows direct access. You can directly access the website through IP, or access it through an unset domain name (for example, someone points his own domain name to your server IP). This easily exposes some websites on the server, so how do we set Nginx to prohibit these behaviors?
server {
listen 80 default_server;
server_name _;
return 404;
}
When the unbound domain name points to your server, if it cannot match the virtual host domain name you configured, this virtual host will be used by default, and then 404 will be returned directly.
listen 80 default_server: Specify the server configuration section as the default host of port 80. That is, when the unbound domain name points to your server, it cannot match the virtual host domain name you configured. After that, this virtual host will be used by default.
server_name _: _ here can be replaced with any other invalid characters or invalid domain name, which means that the server configuration will not be accessed normally.
return 404: means returning 404 error directly.
