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.
[box type=”info” align=”” class=”” width=””]https://ip.add.re.ss:9090[/box]
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”.
Once you have logged in into Cockpit, it will take you to the System page where you can see a complete overview of the system.
That’s it. From here, you can do administrative tasks such as adding/deleting users, starting/stopping services, configuring network and so on.
