红帽全球峰会第 11 章 Booting the installation media
After you have created bootable media, you are ready to boot the Red Hat Enterprise Linux installation.
You can register RHEL by using the Red Hat Content Delivery Network (CDN). CDN is a geographically distributed series of web servers. These servers provide, for example, packages and updates to RHEL hosts with a valid subscription.
During the installation, registering and installing RHEL from the CDN offers following benefits:
- Utilizing the latest packages for an up-to-date system immediately after installation and
- Integrated support for connecting to Red Hat Lightspeed and enabling System Purpose.
11.1. Booting the installation from a network using HTTP
When installing Red Hat Enterprise Linux on a large number of systems simultaneously, the best approach is to boot and install from a server on the local network. You can boot the Red Hat Enterprise Linux installation from a network by using HTTP.
To boot the installation process from a network, you must use a physical network connection, for example, Ethernet. You cannot boot the installation process with a wireless connection.
Prerequisites
- You have configured an HTTP boot server, and there is a network interface in your system. See Additional resources for more information.
- You have configured your system to boot from the network interface. This option is in the UEFI, and can be labeled Network Boot or Boot Services.
- You have verified that the UEFI is configured to boot from the specified network interface and supports the HTTP boot standard. For more information, see your hardware’s documentation.
- Your platform is x86_64 or you install in KVM.
Procedure
- Verify that the network cable is attached. The link indicator light on the network socket should be lit, even if the computer is not switched on.
Turn on the system.
Depending on your hardware, some network setup and diagnostic information can be displayed before your system connects to an HTTP boot server. When connected, a menu is displayed according to the HTTP boot server configuration.
Use the arrow keys on your keyboard to select the boot option that you require, and press Enter to select the boot option. The installation program gets started and you can install Red Hat Enterprise Linux using the graphical or text user interface.
The installation program starts automatically if no action is performed in the boot menu window, by default within 60 seconds.
Optional: Edit the available boot options.
Press E to enter edit mode. Change the predefined command line to add or remove boot options. Press Ctrl+X to confirm your choice.
