Enable the Cockpit service

To start Cockpit automatically on every reboot, run:

# sudo systemctl enable --now cockpit.socket

Allowing Firewall

After we have started our cockpit server and enable it to start in every boot, we’ll now go for configuring firewall. As we have firewall programs running in our server, we’ll need to allow ports in order to make cockpit accessible outside of the server.

# firewall-cmd --permanent --add-service=cockpit
# firewall-cmd --reload

Accessing Cockpit Web Interface

Once you start the Cockpit service, you access the Cockpit console by going to below URL using the browser.

https://ip.add.re.ss:9090
You would need to add a Security Exception in the browser to access the Cockpit for the first time. Log in with your local user account. In my case; it is “root”.
