When I install firewalld on the app servers, it gets installed on all successfully. But on one of the app servers I see an error when I try to start the firewalld service. I have tried this multiple times but run into the same issue every time. Because of this, I am unable to configure firewall on that failed app server and hence unable to complete my task.
Anybody else faced the same issue? Any tips on how to workaround this issue?
thanks,
Sam
