FirewallD is not running [root@VM-16-9-centos mydata]# firewall-cmd --reload FirewallD is not running

FirewallD is a firewall management tool used in CentOS and other Linux distributions. The error message "FirewallD is not running" indicates that the FirewallD service is not currently active or running on your system.

To resolve this issue, you can try starting the FirewallD service using the following command:

sudo systemctl start firewalld

If the service starts successfully, you should see a message indicating that the FirewallD service has started. You can then try running the `firewall-cmd --reload` command again to reload the firewall rules.

If the issue persists, you may need to check if the FirewallD service is enabled to start at boot. You can do this by running the following command:

sudo systemctl enable firewalld

This will ensure that the FirewallD service starts automatically when you boot your system.
