Setting Up a Network Boot Server

To be able to deploy PXE bot images created with KIWI, you need to set up a network boot server providing the services DHCP and atftp.

Installing and Configuring atftp

  1. Install the packages atftp and kiwi-pxeboot.

  2. Edit the file /etc/sysconfig/atftpd. Set or modify the following variables:

    ATFTPD_OPTIONS="--daemon --no-multicast"
    ATFTPD_DIRECTORY="/srv/tftpboot"
    
  3. Start the atftpd service by calling:

    $ systemctl start atftpd.socket
    $ systemctl start atftpd
    

Installing and Configuring DHCP

Contrary to the atftp server setup the following instructions can only serve as an example. Depending on your network structure, the IP addresses, ranges and domain settings need to be adapted to allow the DHCP server to work within your network. If you already have a DHCP server running in your network, make sure that the filename and next-server directives are correctly set on this server.

The following steps describe how to set up a new DHCP server instance using dnsmasq:

  1. Install the dnsmasq package.

  2. Create the file /etc/dnsmasq.conf and insert the following content:

    Note

    Placeholders

    Replace all placeholders (written in uppercase) with data fitting your network setup.

    # Don't function as a DNS server:
    port=0
    
    # Log lots of extra information about DHCP transactions.
    log-dhcp
    
    # Set the root directory for files available via FTP,
    # usually "/srv/tftpboot":
    tftp-root=TFTP_ROOT_DIR
    
    # The boot filename, Server name, Server Ip Address
    dhcp-boot=pxelinux.0,,BOOT_SERVER_IP
    
    # Disable re-use of the DHCP servername and filename fields as extra
    # option space. That's to avoid confusing some old or broken
    # DHCP clients.
    dhcp-no-override
    
    # PXE menu.  The first part is the text displayed to the user.
    # The second is the timeout, in seconds.
    pxe-prompt="Booting FOG Client", 1
    
    # The known types are x86PC, PC98, IA64_EFI, Alpha, Arc_x86,
    # Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI and X86-64_EFI
    # This option is first and will be the default if there is no input
    # from the user.
    pxe-service=X86PC, "Boot to FOG", pxelinux.0
    pxe-service=X86-64_EFI, "Boot to FOG UEFI", ipxe
    pxe-service=BC_EFI, "Boot to FOG UEFI PXE-BC", ipxe
    
    dhcp-range=BOOT_SERVER_IP,proxy
    
  3. Run the dnsmasq server by calling:

    systemctl start dnsmasq
