FirewallD is not running in CentOS Linux 7.1.1503

Question

I wanted to add a port 5004 for tcp connection. So I run the command:

firewall-cmd --permanent --add-port=5004/tcp

However I got an error:

FirewallD is not running

So by some research, I run the command to check the status.

systemctl status firewalld

It shows:

firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled)
Active: inactive (dead)

So what I need to do?

Solution

Try

systemctl restart firewalld

crashed? Try restarting it (sudo) systemctl start firewalld (sudo if you are not root and may run systemctl start as root using it)
