Ubuntu Server Installation

Let’s get started without further ado!

  1. Start by launching your virtual machine using the Ubuntu Server 20.04 ISO. Although VMware is mentioned often in this article, you may use any hypervisor. The examples below are from VMware ESXi 7.0, but other options include Microsoft Hyper-V, VirtualBox, and VMware Player, to mention a few. When your VM guest boots, you should receive system boot notifications as well as the VM guest boot. After the startup procedure is complete, you’ll see the following welcome screen:

English is the default language option. Enter if this is the language you want to use.

2. Select whether or not you want to update the installer on the following page. If you’re connected to the internet, click Enter after selecting ‘Update to the updated installation’ using the arrow keys. You may skip this step if you like.

The update will begin when the installer has finished downloading:

3. After the update is complete, you will be prompted to choose a keyboard layout. The default language is English (US). If you’re OK with the settings, choose Done and press Enter:

4. It’s now time to set up the networking. By default, the installer looks for a DHCP address and configures networking automatically. However, you should now change the IP address to a proper network setup. You might record the allocated address and save it as a static setting. Make careful to make that address a static reservation in your DHCP server setup if you choose this route.

5. Select eth0 and press Enter to set a static address, as shown below. After that, you must choose between IPv4 and IPv6, as well as provide the necessary subnet, address, gateway, and name server addresses. Because the world’s IPv4 address space is running out, IPv6 is predominantly used for internet traffic. It’s unlikely that you’ll ever need to utilize it for local traffic.

In the vast majority of circumstances, you will use IPv4 as indicated below:

6. When you’re done, the settings will take effect, and you’ll be able to continue. To continue, choose Done and click Enter.

7. You’ll be prompted to set up a proxy address on the following page. If you use one to access the internet, type it in here; if not, leave it blank and click Done, then Enter:

The next step is to choose a disk configuration. For the sake of this tutorial, we’ll use the defaults as much as feasible. Make sure that Use a whole disk is chosen, as well as Set up this disk as an LVM group. Choose Done and hit Enter with both options selected:

9. Take a look at the storage setup. It’s also a good idea to record the disk settings at this point. If you’re happy with your settings, choose Done and hit Enter:

Because formatting and dividing a drive is deemed harmful, a confirmation prompt will appear. Press Enter after selecting Continue:

11. The Profile Setup page will appear next. This account will be the server’s root user account. Enter your name, the name of the server, the username, and the password you want to use. Your name or a Marvel Comics character may be used as the username. It’s all up to you. Whatever option you choose, be sure to record this information before moving further!

12. Select Done and hit Enter when you’re through with the information:

13. You will now be asked whether you wish to install OpenSSH Server. If you’ll simply use the VM console to connect to the server, you may skip the installation. OpenSSH may be installed afterwards. If you want to control your host through SSH, make sure Install OpenSSH Server is chosen. It’s simpler to do it now rather than later while installing and configuring. If you’re acquainted with SSH keys, you may import them immediately to allow a safe login without a password.

14. When you’re happy with your choices, choose Done and press Enter:

15. You’re almost finished! The next step is to install some of the most popular snaps for Ubuntu Server.

Select PowerShell and then Done, then click Enter if you wish to. Otherwise, simply press Enter after selecting Done.

The installation of Ubuntu Server will now begin. On a virtual computer, installation usually takes just a few minutes.

16. After a few moments, you must reboot. The server will restart if you press Enter.

Common Ports are being opened.

Installing a firewall will provide some underlying security to your system. The Uncomplicated Firewall (ufw) is neither set or activated by default in Ubuntu Server 20.04.

Technically, the actions in this section aren’t necessary for a vanilla installation. Read on if you want to use this server as a web server or maybe a database server.

Now use the SSH protocol to connect to your new server. SSH is used to run commands in Windows Terminal and PowerShell 7 for this instruction.

Activating the Firewall

  1. Using the login and IP address you provided during the Ubuntu Server installation, open your SSH client and type the following command:

ssh [Root UserName]@[IP Address] ssh [Root UserName]@[IP Address] ssh [Root

2. Hit the Enter key. If you haven’t connected using SSH previously, wait for the request to accept the encryption key. The following animated gif depicts the process:

Type the following command in the terminal to check the status of the Uncomplicated Firewall, or UFW:

The firewall will be turned off. By entering the command below and clicking Enter, you may enable and start the firewall daemon right now:

SSH access should be enabled first. Once you’ve activated the firewall, you’ll need to do this.

If you want to use this Ubuntu server as a web server or a MySQL server, you’ll need to open the ports listed below.

ufw allow http sudo ufw allow https sudo allow mysql sudo ufw

Enter the following command to reload the firewall configuration and implement the changes:

You may want to be more specific about where you let traffic in. Because there are other security mechanisms in place that prohibit access to workstations on the network, this guide may be used everywhere. If you want to learn more about how to setup UFW, you may start here.

Ubuntu Server 20.04 is being updated.

Before continuing on, you’ll want to update the operating system and upgrade any programs that need it. This is a good way to guarantee that your freshly installed server has all of the latest security and issue patches.

Begin by running the apt command, as seen below.

The apt package manager will then look for updates/upgrades in the Ubuntu repository. The -y option disables confirmation dialogs, and any packages with updates will be shown on the screen.

Now execute the following command.

The apt package manager will now begin to install any previously identified upgrades that need updating. Any confirmation dialogs will be suppressed if the -y argument is used. Depending on your internet connection and system speed, this step may take a minute or two.

Congratulations! You’ve just finished installing, configuring, and updating Ubuntu Server 20.04 LTS.
