So, how can I remove the server info in the response header in Ubuntu 18.04 Linux?
#1 Install nginx-extras by running command below:
sudo apt install nginx-extras
#2 Once installation finish, you can update your server block in Nginx configuration by adding one line below to remove server info from the response header:
#3 You may also set the server response to anything else, i.e. set to Google Web Server (gws) just to confuse people (optional).
more_set_headers 'Server: gws';
#4 Finally, retest your Nginx configuration and reload it if no error found.
sudo nginx -t sudo systemctl reload nginx
That’s all. You can read more about the nginx-extras header more module here: Bionic
