CentOS Firewall

I am using CentOS following these instructions https://www.digitalocean.com/community/tutorials/additional-recommended-steps-for-new-centos-7-servers on a new droplet. Any idea what’s wrong?

$ **sudo systemctl start firewalld**
[sudo] password for xxx:
Failed to start firewalld.service: Unit not found.
$

nvm. I had to first: sudo yum install firewalld

The tutorial makes no mention of it.

Thanks!
