You can skip the whole section of the following manual setup instruction by using this non-official tool. We will also assume your tftp root path is /var/lib/tftpboot in the remaining of this article. It is expected to show active (running) from the output messages. If the installation is successful, check the corresponding TFTP service is active by this command: $ systemctl status rvice
This article assumes that you have setup your tftp (and/or DHCP/bootp if necessary, depending on your LAN configuration) by following this Ubuntu Discourse post, or you could also consider build your own tftp in this way if your DNS and DHCP is already well configured: $ sudo apt install tftpd-hpa Focal (20.04, 20.04.3) and Groovy (20.10) have been tested with the following method. This process is inpired by this Ubuntu Discourse post for legacy mode, which is UEFI’s predecessor. The process is applicable to both of the architectures, arm64 and amd64. This document provides the steps needed to install an system via netbooting and subiquity in UEFI mode with Ubuntu 20.04 (or later). A more advanced iPXE script could, for example, default to booting an operation system from the local disk and only go to the netboot operation if a user pressed a key before a countdown timer reached zero.Netbooting the Live Server Installer via UEFI PXE on Arm (aarch64, arm64) and x86_64 (amd64)
Most notably, iPXE has support for interactive boot menus which can be configured with a default selection and a timeout. Much more complex configurations are possible.
NOTE: The above boot script shows a minimal example of how to get iPXE to netboot Linux. # DEFAULT_DEV=$(ip route show default | awk '/initramfs-$DEFAULT_VER.img The following sequence of commands should find and reconfigure your default network connection appropriately: # MY_DNS1=192.0.2.91 Next, we need a static network address on our server. You may want to disable the console logging temporarily by running: sysctl -w kernel.printk=0 NOTE: Fedora 28 Server tends to dump a lot of logging output to the console by default.
Beware that if you log out, the variable assignments will be cleared. Any value that you might need to customize will be stated as a MY_* variable that you can tweak before running the remaining commands. NOTE: This guide is meant to be copy-and-paste friendly. NOTE: Red Hat recommends that both static and transient names match the fully-qualified domain name (FQDN) used for the machine in DNS, such as ( Understanding Host Names). Once you have your minimal installation of Fedora Server up and running, log in and then become root using this command: $ sudo -i If you start with a different version of Fedora, then you may need to do some troubleshooting if an expected file or command is not available. NOTE: For this tutorial we will be using Fedora 28. Other versions may include a slightly different set of packages in their “Minimal Install”. We just need a typical “Minimal Install” of Fedora Server for our starting point and we will use the command line to add any additional packages that are needed after the installation is finished. Start by downloading one of Fedora Server’s netinst images, burning it to a CD, and booting the server that will be reformatted from it. Part 2 will show how to add Kerberos-authenticated home directories to the netboot configuration. Part 1 of this tutorial will cover creating a netboot server and image. A netboot server can be set up to serve an entire operating system over a network so that the client computers can be configured from one central location. This tutorial will show one method of building a netboot server. One such environment would be a school computer lab.
Some computer networks need to maintain identical software installations and configurations on several physical machines.
