Enabling the firewall

Enable your firewall so that it can work together with the Apache HTTPS server.

1. Start the firewall, and then give the http and https services permission to access the firewall.

   
   # systemctl start firewalld.service
   # firewall-cmd --add-service http --permanent
   success
   # firewall-cmd --add-service https --permanent
   success 
   

2. Restart the firewall in order to make your permission changes active and automatically enable the firewall service on boot.

   
   # systemctl restart firewalld.service
   # systemctl enable firewalld.service
   ln -s '/usr/lib/systemd/system/firewalld.service' 
     '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
   ln -s '/usr/lib/systemd/system/firewalld.service' 
     '/etc/systemd/system/basic.target.wants/firewalld.service'
