Remove all server info for nginx

nginx, by default, sends information about its use in the Server HTTP header as well as error pages. For example:

nginx/1.22.1

Install additional packages

To remove this, you'll need additional package to be installed:

• libnginx-mod-http-headers-more-filter in Debian
• nginx-module-headers-more - in RHEL

For example in Debian:

sudo apt install libnginx-mod-http-headers-more-filter

Modify nginx config

Modify the following lines in the /etc/nginx/nginx.conf:

http {
...
        server_tokens off;
        more_clear_headers Server;
...
}

Restart nginx:

sudo systemctl restart nginx

Test

Test webserver with curl:

curl -svI qwerty.md
