What is Ubuntu Server?

Ubuntu Server is an open-source operating system that is widely used in web servers, cloud computing, and data centers. It’s a powerful and reliable operating system that’s perfect for handling server applications and tasks. Whether you’re setting up a web server, file server, or application server, Ubuntu Server is a great choice.

Why Choose Ubuntu Server?

There are several reasons why Ubuntu Server is a popular choice among system administrators. First and foremost, it’s free to use and open source. This means you can download and install it without any license fees. Additionally, Ubuntu Server is highly customizable and has a large community of developers and users who contribute to its development and improvement.

Ubuntu Server also has a wide range of software packages available through its package manager, making it easy to install and configure additional software. And because Linux is known for being secure and stable, you can trust that your server will be reliable and safe from security threats.

Preparing for Installation

Before we begin the installation process, there are a few things you should do to prepare. First, make sure your server meets the minimum system requirements for Ubuntu Server 16.04. You’ll need at least 512MB of RAM and 2GB of disk space.

You’ll also need to download the Ubuntu Server 16.04 ISO file from the official website. Once you’ve downloaded the ISO file, you can create a bootable USB drive using software like Rufus or Etcher.

Once you have your bootable USB drive, you’re ready to begin the installation process!

Installing Ubuntu Server 16.04

Step 1: Boot from USB

To begin the installation process, insert your bootable USB drive into your server and power it on. You may need to change your BIOS settings to ensure that your server boots from the USB drive.

Step 2: Choose Language and Keyboard Layout

Once your server has booted from the USB drive, you’ll be presented with the Ubuntu Server installation wizard. Choose your language and keyboard layout and click “Continue.”

Step 3: Configure Network Settings

The next step is to configure your network settings. If you’re installing Ubuntu Server on a virtual machine, you can choose to configure your network settings automatically. If you’re installing Ubuntu Server on a physical machine, you’ll need to manually configure your network settings.

You’ll need to provide your server with a hostname, choose a domain name, and set up your IP address, netmask, gateway, and DNS servers.

Step 4: Partition Your Disk

Once your network settings are configured, you’ll need to partition your disk. You can choose to use the entire disk or manually partition it.

If you’re not sure how to partition your disk, we recommend choosing the “Guided – use entire disk” option. This will automatically partition your disk for you.

Step 5: Create User and Password

The next step is to create a user and password for your Ubuntu Server. This user will have administrative privileges, so make sure you choose a strong password.

Step 6: Install Software

After you’ve configured your disk and user account, you’ll be prompted to choose which software packages to install. If you’re not sure what to choose, we recommend selecting “OpenSSH server” and “standard system utilities.”

Step 7: Reboot Your Server

Once the installation process is complete, you’ll need to reboot your server. Remove the USB drive and restart your server.

Uncomment the line that reads “Port 22” and change the port number if desired.
