How to Install and Use Cockpit on Ubuntu 20.04

The Cockpit is a web-based tool that helps system administrators perform day-to-day administrative tasks from a web browser. You can monitor system resources, create and remove user accounts, start and stop services, restart and shut down the system, and create and manage virtual boxes using the Cockpit. Cockpit makes it easier to administer your Linux server via a web-based interface.

In this tutorial, we will show you how to install and use Cockpit on Ubuntu 20.04.

Prerequisites

• A fresh Ubuntu 20.04 server on the Atlantic.Net Cloud Platform
• A root password configured on your server

Step 1 – Create Atlantic.Net Cloud Server

First, log in to your Atlantic.Net Cloud Server. Create a new server, choosing Ubuntu 20.04 as the operating system with at least 2GB RAM. Connect to your Cloud Server via SSH and log in using the credentials highlighted at the top of the page.

Once you are logged in to your Ubuntu 20.04 server, run the following command to update your base system with the latest available packages.

apt-get update -y

Step 2 – Install Cockpit

By default, the Cockpit package is included in the Ubuntu default repository. You can install it by just running the following command:

apt-get install cockpit -y

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

systemctl start cockpit
systemctl enable cockpit

You can also verify the status of the Cockpit service with the following command:

systemctl status cockpit

You should get the following output:

• cockpit.service - Cockpit Web Service
