sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload

Verify Apache Installation

Every process in Apache is managed with the systemctl command. Verify the installation of Apache with the following command.

sudo systemctl status httpd
