Cockpit is a free and open-source remote management software sponsored by Red Hat. It provides a web-based interface to manage and monitor a Linux-based server through a web browser. It runs on several operating systems, including Debian, Ubuntu, CentOS, Fedora, RHEL, and Arch Linux. With Cockpit, you can perform server management tasks remotely, such as manage services, create user accounts, monitor system, configure networks, inspect log, system update, manage firewall, domain management, setup OpenVPN, and many more. It also supports Kubernetes and Openshift cluster. Cockpit also provides graphs and easy-to-use forms to measure system performance and make changes to your systems.

In this tutorial, we will explain how to install Cockpit on Debian 10.

Step 1 – Install Cockpit

By default, Cockpit is available in the Debian 10 default repository. You can install it by simply running the following command:

apt-get update -y
apt-get install cockpit -y

Once Cockpit is installed, start the Cockpit service and enable it to start at system reboot with the following command:

systemctl start cockpit
systemctl enable cockpit
You can also verify the status of Cockpit with the following command:
systemctl status cockpit

You should get the following output:
