### Ubuntu Server 24.04 Installation Guide Step-by-Step Ubuntu Server 24.04 is the latest version of the popular Linux-based server operating system, and it provides a robust platform for deploying servers, containers, and cloud environments. Below is a comprehensive guide to installing Ubuntu Server 24.04 step-by-step. #### Preparation Before beginning the installation process, ensure that you have the following prerequisites in place: - A computer or virtual machine capable of running Ubuntu Server. - A USB drive (at least 8GB) or an ISO image of Ubuntu Server 24.04[^1]. - Internet access for package updates and additional software installations. #### Step 1: Downloading the ISO Image Download the official Ubuntu Server 24.04 ISO image from the [Ubuntu website](https://ubuntu.com/download/server). This ensures that you are using a verified and secure source for your installation media[^1]. #### Step 2: Creating a Bootable USB Drive Use tools like **Rufus** (for Windows) or **balenaEtcher** (cross-platform) to create a bootable USB drive with the downloaded ISO image. Ensure that the USB drive is formatted properly before proceeding[^2]. ```bash # Example command to write the ISO to a USB drive on Linux sudo dd if=/path/to/ubuntu-server-24.04.iso of=/dev/sdX bs=4M status=progress && sync ``` #### Step 3: Booting from the USB Drive Insert the USB drive into your target machine and reboot it. Access the BIOS/UEFI settings by pressing a key such as `F2`, `Del`, or `Esc` during startup. Set the USB drive as the primary boot device and save the changes[^3]. #### Step 4: Initial Setup Once booted, you will be presented with the Ubuntu Server installer interface. Follow these steps: 1. Select your language and press Enter. 2. Choose "Install Ubuntu Server" and confirm the keyboard layout. 3. Configure the network settings: - Provide a hostname for your server. - Set up user accounts, including a root password and a standard user account[^4]. #### Step 5: Disk Partitioning Choose how you want to partition your disk: - **Guided storage setup**: Automatically partitions the disk. - **Manual storage setup**: Allows customization of partition sizes and mount points[^5]. #### Step 6: Package Updates and Installation The installer will prompt you to update packages during installation. It is recommended to enable this option to ensure that your system has the latest security patches and bug fixes. #### Step 7: Additional Software Selection Select any additional software that you may need, such as OpenSSH server for remote access or LXD for container management. These selections can be made through the installer menu[^2]. #### Step 8: Finalizing the Installation After the installation completes, remove the USB drive and reboot the system. Log in using the credentials created during the setup process. #### Post-Installation Configuration 1. Update the system: ```bash sudo apt update && sudo apt upgrade -y ``` 2. Install essential utilities: ```bash sudo apt install -y vim git curl wget ``` #### Optional Configurations - **TimescaleDB Installation**: If you plan to use TimescaleDB, follow the prerequisite steps outlined in the provided reference[^3]. - **NVIDIA Container Toolkit**: For GPU-accelerated workloads, configure the NVIDIA Container Toolkit as described in the reference material. ---
