Install Ubuntu Server 18.04 LTS

In this tutorial, we will show you how to install the latest server version that will enable you to run applications and other services.

Installation Requirements

Before getting started, ensure you have the following in your checklist

  • Installation Media – USB drive or DVD
  • ISO image of Ubuntu server 18.04 LTS You can download the ISO from this link
  • 2 GHz Dual Core processor
  • 25 GB of Hard Disk space
  • Installation Media ( Either DVD / USB drive)
  • Internet Access for downloading necessary updates

With the above requirements met, we’re all set and ready to go!

Install Ubuntu Server 18.04

Step 1: Burn the ISO Image

The first step is to burn the ISO image onto a blank DVD or make a USB drive bootable. There are plenty of free software tools at your disposal for this task.

Here are a couple of such tools:

Power ISO  – A powerful DVD, CD burning software. Check out the official website

Rufus – Used for making your USB drive bootable. Check out the official website

When the process is complete, take the DVD and insert it into the drive of the computer you want to install the server on.

Ensure that your installation medium is set as the priority in the ‘Boot Order of the System’ set up. After that, you can restart your system and get rolling!

Step 2. Choose the Language

After setting the boot order, you’ll be presented with the screen shown below, which requires you to choose your preferred language. Make your selection and hit ‘ENTER.’

Step 3. Select Keyboard Layout

Next, select the preferred keyboard layout and hit ‘ENTER.’

Step 4. Select Ubuntu or MAAS (Metal As A Service)

You will then have a list of various platforms to install Ubuntu. Select the first choice to install Ubuntu generally on a PC. The other two options, titled ‘Install MAAS’, facilitate cloud provisioning for physical servers.

Since we are doing the installation on a PC, we select the first choice and hit ENTER.

Step 5. Network Settings

At this point, you will be required to select the network adapter and accept the automatic assignment of the IP address if your system is configured in a DHCP server environment. Alternatively, you can choose to set the IP address manually.

In this example, the server has obtained IP from a DHCP server using the network adapter enp0s3.

Step 8. Hard Disk Setup

This step prompts you to configure your hard disk as per your usage of the disc during the installation process.

You have the freedom to use the entire disk if no other operating system is installed or you can opt to configure manually and make a few changes

Step 9. Choose a hard drive to install to

Next, select the hard disk you are going to install Ubuntu server 18.04 on. In this case, I’m using VirtualBox to install Ubuntu server 18.04.

If you have multiple hard drives, they will be listed for you to select.

Step 10. File System Summary

Now you can verify if everything is OK and click done.

If you wish to start all over with the disk setup and partitioning, hit ‘RESET.’

Step 13. Select Server snaps

This is a new step in the installation of Ubuntu Server. This step allows you to choose from a list of selected Server Snaps. What this means is that you can choose to have a pre-configured server.

Some of the choices include

  • Kubernetes
  • Docker
  • Next cloud
  • Canonical Live patch

Select your preferred option, or if you do not wish to have any of them, hit ENTER.

The installation process will begin. This will take about 10 minutes, although it could vary depending on the RAM and CPU of your server.
