Here at Bobcares, we receive requests to fix such firewall-cmd errors as a part of our Server Management Services.

Today, let’s see the cause of this error and see how our Support Engineers fix it.

Why does firewall-cmd: command not found shows up?

The command not found error shows up if the firewalld tool is not enabled on the server. Also, we’ve seen sometimes if the path doesn’t contain /usr/bin then this error pops up.

Among the above, the error mostly occurs due to the missing firewalld tool. So, we simply fix it by installing the firewalld.

Let us discuss how our Support Engineers install firewalld and resolve the error.

firewall-cmd: command not found

Our Support Engineers started troubleshooting the error by checking the status of the firewalld by running the command

systemctl status firewalld

And here is the result.

So, we installed the firewalld by running the command:

yum install firewalld

After that, we start the firewall using the command:

systemctl start firewalld

To enable the service to auto-start at boot time we use the command:

systemctl enable firewalld

Then, we checked for its status using the command:

systemctl status firewalld

Once we saw the status is enabled, now we can run the firewall-cmd to open a port 80

firewall-cmd --zone=public --add-port=80/tcp --permanent

Lastly, we reloaded it using the command

firewall-cmd --reload

Finally, this fixed the error.
