How to install Ubuntu Live Server 20.04?
There are two main options to install Ubuntu Live Server 20.04: installing from a USB flash drive or a DVD or installing from a network using PXE booting. We will explain both options in detail below.
Option 1: Install from a USB flash drive or a DVD
This option is recommended if you have a USB flash drive or a DVD with enough capacity to store the ISO image of Ubuntu Live Server 20.04 and you want to install it on a computer that can boot from a USB flash drive or a DVD. The steps are as follows:
Step 1: Create a bootable USB flash drive or a DVD using the ISO image
To create a bootable USB flash drive or a DVD, you need a software application that can write the ISO image of Ubuntu Live Server 20.04 to your USB flash drive or your DVD. There are many software applications available for different operating systems, such as , and more. You can choose any software application that suits your preferences and use it to create a bootable USB flash drive or a DVD with the ISO image of Ubuntu Live Server 20.04.
Step 2: Insert the USB flash drive or the DVD into the computer you want to install Ubuntu Live Server on
Once you have created a bootable USB flash drive or a DVD, you need to insert it into the computer you want to install Ubuntu Live Server on. Make sure that the computer is turned off before you insert the USB flash drive or the DVD.
Step 3: Boot from the USB flash drive or the DVD and follow the installation instructions
After you have inserted the USB flash drive or the DVD, you need to turn on the computer and press the appropriate key to enter the boot menu. The key may vary depending on your computer model and manufacturer, but it is usually one of the following: F2, F8, F10, F12, Esc, or Del. Once you enter the boot menu, you need to select the option that says "USB" or "DVD" and press Enter. This will start booting from the USB flash drive or the DVD and launch the Ubuntu Live Server installer. You will see a welcome screen that asks you to choose your language and keyboard layout. After that, you will see a series of screens that guide you through the installation process. You will need to choose your time zone, your network configuration, your storage configuration, your server profile, your user account, and your security settings. You can also choose to install additional software packages or snap applications if you want. Once you have completed all the steps, you will see a confirmation screen that says "Installation complete". You can then reboot your computer and enjoy your Ubuntu Live Server 20.04.
Option 2: Install from a network using PXE booting
This option is recommended if you do not have a USB flash drive or a DVD with enough capacity to store the ISO image of Ubuntu Live Server 20.04 and you want to install it on a computer that can boot from a network using PXE booting. PXE booting is a method that allows you to boot and install an operating system from a network server without using any local storage media. The steps are as follows:
Step 1: Set up a PXE server on another computer with Ubuntu Live Server installed
To set up a PXE server, you need another computer with Ubuntu Live Server installed and connected to the same network as the computer you want to install Ubuntu Live Server on. You also need to install some packages on the PXE server that enable it to serve files over the network using TFTP (Trivial File Transfer Protocol) and DHCP (Dynamic Host Configuration Protocol). You can install these packages by running the following commands in the terminal:
sudo apt update sudo apt install tftpd-hpa isc-dhcp-server syslinux-common pxelinux
After installing these packages, you need to configure them by editing some files in the /etc directory. You can use any text editor of your choice, such as nano, vim, or gedit.
Step 2: Configure the PXE server to serve the ISO image of Ubuntu Live Server 20.04
To configure the PXE server to serve the ISO image of Ubuntu Live Server 20.04, you need to do three things: copy the ISO image to the /var/lib/tftpboot directory, create a configuration file for pxelinux in the /var/lib/tftpboot/pxelinux.cfg directory, and edit the configuration file for dhcpd in the /etc/dhcp directory. The steps are as follows:
Step 2.1: Copy the ISO image to the /var/lib/tftpboot directory
To copy the ISO image of Ubuntu Live Server 20.04 to the /var/lib/tftpboot directory, you need to use the cp command in the terminal. For example, if you have downloaded the ISO image to your Downloads folder, you can run the following command:
sudo cp /Downloads/ubuntu-20.04.3-live-server-amd64.iso /var/lib/tftpboot
This will copy the ISO image to the /var/lib/tftpboot directory, which is the default directory for serving files over TFTP.
Step 2.2: Create a configuration file for pxelinux in the /var/lib/tftpboot/pxelinux.cfg directory
To create a configuration file for pxelinux in the /var/lib/tftpboot/pxelinux.cfg directory, you need to use a text editor and create a file named default. This file will contain the instructions for pxelinux on how to boot and install Ubuntu Live Server 20.04 from the ISO image. You can use the following template for the configuration file:
default ubuntu label ubuntu kernel memdisk append iso initrd=ubuntu-20.04.3-live-server-amd64.iso raw
This configuration file tells pxelinux to load a kernel named memdisk, which is a tool that allows booting from an ISO image in memory, and to append an initrd parameter with the name and location of the ISO image. The raw parameter tells memdisk to treat the ISO image as a raw disk image.
Step 2.3: Edit the configuration file for dhcpd in the /etc/dhcp directory
To edit the configuration file for dhcpd in the /etc/dhcp directory, you need to use a text editor and edit a file named dhcpd.conf. This file will contain the settings for dhcpd on how to assign IP addresses and other network parameters to the clients that request them. You can use the following template for the configuration file:
option domain-name "example.com"; option domain-name-servers ns1.example.com, ns2.example.com; default-lease-time 600; max-lease-time 7200; ddns-update-style none; subnet 192.168.1.0 netmask 255.255.255.0 range 192.168.1.100 192.168.1.200; option routers 192.168.1.1; option broadcast-address 192.168.1.255; next-server 192.168.1.10; filename "pxelinux/pxelinux.bin";
This configuration file tells dhcpd to assign IP addresses from 192.168.1.100 to 192.168.1.200 to the clients that request them, and to provide them with other network parameters, such as domain name, domain name servers, routers, and broadcast address. The next-server parameter specifies the IP address of the PXE server (in this case, 192.168.1.10), and the filename parameter specifies the location of the pxelinux binary file that will be loaded by the clients.
Step 2: Restart tftpd-hpa and isc-dhcp-server services
After editing these files, you need to restart tftpd-hpa and isc-dhcp-server services by running the following commands in the terminal:
sudo systemctl restart tftpd-hpa sudo systemctl restart isc-dhcp-server
This will apply the changes and start serving files over TFTP and DHCP.
Step 3: Connect the computer you want to install Ubuntu Live Server on to the same network as the PXE server
To install Ubuntu Live Server 20.04 from a network using PXE booting, you need to connect the computer you want to install it on to the same network as the PXE server. You can use an Ethernet cable or a Wi-Fi connection, depending on your network setup. Make sure that the computer is turned off before you connect it to the network.
Step 4: Boot from the network and follow the installation instructions
After you have connected the computer to the network, you need to turn on the computer and press the appropriate key to enter the BIOS or UEFI settings. The key may vary depending on your computer model and manufacturer, but it is usually one of the following: F2, F8, F10, F12, Esc, or Del. Once you enter the BIOS or UEFI settings, you need to change the boot order and select the option that says "Network" or "PXE" as the first boot device. This will enable the computer to boot from the network and load the pxelinux binary file from the PXE server. You will see a menu that allows you to choose between different options, such as "ubuntu", "ubuntu (safe graphics)", "OEM install (for manufacturers)", and "Check disc for defects". You should choose the option that says "ubuntu" and press Enter. This will start booting and installing Ubuntu Live Server 20.04 from the ISO image served by the PXE server. You will see a welcome screen that asks you to choose your language and keyboard layout. After that, you will see a series of screens that guide you through the installation process. You will need to choose your time zone, your network configuration, your storage configuration, your server profile, your user account, and your security settings. You can also choose to install additional software packages or snap applications if you want. Once you have completed all the steps, you will see a confirmation screen that says "Installation complete". You can then reboot your computer and enjoy your Ubuntu Live Server 20.04.
