The course continues by explaining the differences between virtualisation, clouds and containers.
This includes using AppArmor which is installed by default in Ubuntu, and determines exactly what data can be accessed by each program.

There's also a detailed 'security' video on how to harden your new server. The following videos then allow you to consolidate what you've learned so far and learn about specific types of setups such as DNS, databases and mail servers. The networking section details various interfaces, as well as Udev, Upstart and managing the firewall. This section also briefly mentions the handy 'screen' tool which allows you to run multiple programs at once. This is essential knowledge for anyone creating their own server. The initial setup section also explains the difference between the official Ubuntu repositories and those managed by third-parties. The installation guide also shows how to configure a virtual machine to boot from an Ubuntu ISO image. This means it only takes a few minutes to create the installation USB drive.

The install process advises using the cross-platform utility UNetbootin to install the minimal Ubuntu ISO, which is only around 40MB in size. The hard drives topic in particular is an excellent guide for would-be server administrators, as it explains the differences between partition types. The next sections focus on hard drives, installation and setup. However, as you'll be interacting with the server via SSH, the videos do not seem to be dated.
The setup process covered in the training course is for Ubuntu 13.04 LTS, which is no longer supported. This section also details the lifecycle of Ubuntu and distinguishes it from Debian, the distro on which it's based. Some of the videos also have a quiz section to allow you to check what you've learned so far.Īlthough Ubuntu has become most famous (and popular) for being a desktop distribution, the instructor takes some time to explain the advantages of Ubuntu Server at the start of the course, such as the benefits of employing an LTS (Long Term Support) distro. The website also allows you to record notes in a special tab as you watch each video, and every clip comes with a video transcript, which you can copy into the notes tab and annotate to your heart's content. The app, like the website, can keep track of which videos you've already played.
Assuming you're comfortable with the basics of setting up your own virtual machine and have an Ubuntu ISO image, you can get started by watching the 20 training videos that make up the Ubuntu course.ĬBT Nuggets has gone to some lengths to make this a painless process for you, as instead of watching videos on your computer, you can download a mobile app to an Android, Apple or Amazon device and watch them there.
