How to Enable Cockpit Server Manager in AlmaLinux 10

---

The cockpit is an easy-to-use and simple yet powerful remote manager for GNU/Linux servers, it’s an interactive server administration user interface that offers a live Linux session via a web browser.

Install Cockpit Server Manager

---

dnf install cockpit

Check latest versions here : Cockpit.

Enable the service to start onboot,

systemctl enable --now cockpit.socket

Allow the service to run through the firewall,

firewall-cmd --permanent --zone=public --add-service=cockpit
firewall-cmd --reload

If you see any warnings like,

[root@drop ~]# firewall-cmd --permanent --zone=public --add-service=cockpit
Warning: ALREADY_ENABLED: cockpit    success

You can ignore the warning and proceed ahead.

Allow Root User to Log in to Cockpit

---

By default, Cockpit blocks the root user. To enable root login:

nano /etc/cockpit/disallowed-users

Change this:

root

To this:

# root

Or delete the root line entirely.

Then restart the Cockpit service:

systemctl restart cockpit.socket

Next, open the following URL in your browser, it will error due to the invalid SSL certificate, you can use LetsEncrypt to set up a valid SSL certificate as needed.

https://YOUR-VPS-IP-ADDRESS:9090

Replace "YOUR-VPS-IP-ADDRESS" with your VPSes IP address

Here you can enter your root username/password (SSH Login Details) and it will take you into the Cockpit server manager!

Please note, 

1. The web page might render a blank screen in Chrome due to the self-signed/invalid SSL certificate used by default in Cockpit.  
2. Use Firefox in such a scenario where you do not have an SSL Certificate/Domain to bind the service too.

The Cockpit service User Interface

Within the Cockpit server manager, you can manage nearly all parts of your server from Software Updates, monitoring CPU/RAM Usage, and accessing your Terminal as well.

Now you have successfully installed Cockpit Server Manager in your AlmaLinux 10.
