How to open web server ports in Fedora via the command line

The firewall-cmd tool has a neat feature in that it knows what ports are used for certain services. This is handy for things like web server ports which our tired brains may forget from time to time (hint: it’s 80 for http and 443 for https). Even without knowing those numbers, we can still open those ports from the command line like so:

firewall-cmd --add-service http --permanent
firewall-cmd --add-service https --permanent
systemctl restart firewalld

This will open both 80 and 443 on the firewall, and it’ll remain a permanent fixture (i.e. survive a restart). The last nice restarts the firewall, without which the changes won’t come into effect.

You can see a list of added services via

firewall-cmd --list-all

Should you ever need to remove a service again, use the –remove-service option.
