# Installing Ubuntu Server 24.04 LTS

Wondering how to set up a fresh Ubuntu Server 24.04 LTS on your hardware? This guide provides a comprehensive, step-by-step walkthrough for installing Ubuntu Server, covering essential configurations like disk partitioning, network setup, and initial system administration. This process is crucial whether you're setting up a new home server or deploying a dedicated server, such as those offered by [PowerVPS](https://powervps.net/?from=32), which provide full root access for maximum control.

## Prerequisites

Before you begin the installation, ensure you have the following:

* **Ubuntu Server 24.04 LTS ISO Image:** Download the latest LTS (Long Term Support) version from the official Ubuntu website. LTS releases are supported for five years, making them ideal for stable server environments.
* **Bootable Installation Media:** Create a bootable USB drive or DVD from the ISO image. Tools like Rufus (Windows) or balenaEtcher (cross-platform) can help with this.
* **Target Hardware:** A physical server or virtual machine with sufficient resources (at least 2GB RAM and 20GB disk space recommended).
* **Internet Connection:** Required for downloading updates and software during installation.
* **Basic Linux Command Line Familiarity:** While this guide is beginner-friendly, understanding basic commands will be beneficial.

## Starting the Installation

1. **Boot from Installation Media:** Insert your bootable USB/DVD into the server and restart it. Access your server's BIOS/UEFI settings to set the boot order to prioritize the installation media.
2. **Select Language:** Upon booting, you will be presented with a boot menu. Select your preferred language for the installation process and press Enter.
3. **Choose Installation Type:** You'll be asked to choose between "Ubuntu Server" and "Ubuntu Server (minimized)". For a more complete set of tools, select "Ubuntu Server". The minimized option installs a very basic system, requiring more manual package installation later.

## Network Configuration

Proper network configuration is vital for server accessibility.

1. **Network Interface Detection:** The installer will attempt to detect your network interfaces. If you have multiple network cards, select the one you wish to configure for your primary network connection.
2. **DHCP or Static IP:**
* **DHCP (Dynamic Host Configuration Protocol):** If your network has a DHCP server (common in home or small office networks), you can select "DHCP" to automatically obtain an IP address.
* **Static IP:** For servers, a static IP address is generally preferred, ensuring it's always reachable at the same address. Select "Manual" and enter the following details:
* **IP Address:** e.g., `192.168.1.100`
* **Subnet Mask:** e.g., `255.255.255.0`
* **Gateway:** e.g., `192.168.1.1`
* **DNS Servers:** e.g., `8.8.8.8`, `8.8.4.4`
You will configure the network interface name (e.g., `ens18`) and whether to use IPv4 and/or IPv6.

## Disk Partitioning

Careful disk partitioning ensures efficient storage management and can simplify future upgrades.

1. **Guided Partitioning:** For beginners, the "Guided - use entire disk" option is the simplest. It automatically creates partitions for your system.
2. **Guided - use entire disk and set up LVM (Logical Volume Management):** This is a recommended option for flexibility. LVM allows you to resize partitions more easily later, similar to how you might expand a filing cabinet if you run out of space.
3. **Manual Partitioning:** For advanced users, this allows full control over partition sizes and types. You will typically create at least:
* `/boot`: For bootloader files (e.g., 1GB).
* `swap`: For virtual memory (size depends on RAM, often equal to RAM or double).
* `/`: The root filesystem, where most of your operating system and applications will reside (remaining space).

After selecting your partitioning method, review the proposed layout and confirm to proceed.

## Initial System Setup

This section covers essential user and software configuration.

1. **Profile Setup:**
* **Your name:** Enter your full name (optional).
* **Server's name:** This is the hostname of your server, how it will be identified on the network (e.g., `my-ubuntu-server`).
* **Username:** Create a regular user account for yourself. This account will have administrative privileges when needed.
* **Password:** Choose a strong, unique password for your user account.
2. **SSH Setup:**
* **Install OpenSSH server:** It is highly recommended to select "Install OpenSSH server". This allows you to connect to your server remotely using SSH (Secure Shell), a secure encrypted protocol for command-line access.
3. **Featured Server Snaps:** The installer may offer to install popular server applications as "snaps" (a package management system). You can choose to skip this or select applications like Docker if needed.

## Completing the Installation

1. **Installation Progress:** The installer will now copy files and configure your system. This can take some time.
2. **Reboot:** Once the installation is complete, you will be prompted to remove the installation media and reboot the server.

## First Boot and Post-Installation

After rebooting, you will be greeted by the Ubuntu Server login prompt.

1. **Login:** Log in with the username and password you created during the installation.
2. **Update System:** It's crucial to update your system to the latest packages and security patches.
```bash
sudo apt update
sudo apt upgrade -y
```
* `sudo` (superuser do) allows you to run commands with administrative privileges.
* `apt` is the package manager for Ubuntu.
* `update` refreshes the list of available packages.
* `upgrade` installs newer versions of installed packages.
* `-y` automatically answers "yes" to prompts.
3. **Configure Firewall:** Ubuntu comes with `ufw` (Uncomplicated Firewall). It's essential to enable it and allow necessary services.
```bash
sudo ufw enable
sudo ufw allow ssh
sudo ufw status
```
This enables the firewall, allows incoming SSH connections (port 22), and shows the current firewall status.

## Troubleshooting

* **No Network Connectivity:** Double-check your network cable, router settings, and static IP configuration if used.
* **Boot Issues:** Ensure the boot order is correct in your BIOS/UEFI. If you used LVM, verify the LVM configuration.
* **Login Problems:** Verify you are using the correct username and password. If you forgot your password, you may need to boot into recovery mode.
* **Package Installation Errors:** Ensure your network connection is stable and that your `/etc/apt/sources.list` file is correctly configured.

## Next Steps

With Ubuntu Server 24.04 LTS installed, you can now proceed to install and configure your desired applications and services. Consider exploring:

* [[Installing Docker on Ubuntu Server]]
* [[Setting up a LAMP Stack]]
* [[Configuring SSH Key-Based Authentication]]
