Ben's notes

Installs a UEFI PXE server with Arch Linux installer and UEFI shell boot options.

• Install prerequisites:

  yum install tftp-server dhcp xinetd grub2-efi grub2-efi-modules

• Configure DHCPd /etc/dhcp/dhcpd.conf

  subnet 10.10.10.0 netmask 255.255.255.0 {
    range 10.10.10.200 10.10.10.250;
    option domain-name "<domain>";
    option domain-name-servers <nameserver1>, <nameserver2>;
    option ntp-servers <ntp1>, <ntp2>;
    option routers 10.10.10.1;
    next-server <this_pxeserver>;
    filename "/boot/grub/x86_64-efi/core.efi";
  
    default-lease-time 600;
    max-lease-time 7200;
  }

• Enable and start DHCPd:

  systemctl enable dhcpd
  systemctl start dhcpd

• Configure the firewall:

  firewall-cmd --zone public --add-service=dhcp --permanent
  firewall-cmd --zone public --add-service=tftp --permanent
  firewall-cmd --zone public --add-service=http --permanent
  firewall-cmd --reload

• Configure xinetd /etc/xinetd.d/tftp

  	disable			= no

• Enable and start xinetd:

  systemctl enable xinetd
  systemctl start xinetd

• Create grub configuration, this is een Arch linux install example:

  mkdir -p /var/lib/tftpboot/boot/grub/
  vi /var/lib/tftpboot/boot/grub/grub.cfg

  set timeout=5
  
  menuentry 'archlinux-2017.07.01-x86_64' --class os {
       insmod all_video
  
       echo 'Network config:'
       net_ls_cards
       net_ls_addr
       net_ls_routes
  
       set root=http,<this_pxeserver>
       
       echo 'Loading Linux...'
       linuxefi /arch/boot/x86_64/vmlinuz archisobasedir=arch archiso_http_srv=http://<this_pxeserver>/ archisobasedir=arch ip=:::::eth0:dhcp
  
       echo 'Loading Intel micro code, initrd...'
       initrdefi /arch/boot/intel_ucode.img /arch/boot/x86_64/archiso.img
  }
  
  menuentry 'UEFI Shell' {
    chainloader ($root)/boot/uefishell/Shell.efi
  }
  

• Create network bootable grub:

  grub2-mknetdir --net-directory=/var/lib/tftpboot --subdir=/boot/grub -d /usr/lib/grub/x86_64-efi/

• Add Arch ISO:

  curl -O http://ftp.nluug.nl/os/Linux/distr/archlinux/iso/2017.07.01/archlinux-2017.07.01-x86_64.iso
  mount archlinux-2017.07.01-x86_64.iso /mnt
  cp -R /mnt/* /var/www/html

• Add UEFI Shell:

  mkdir -p /var/lib/tftpboot/boot/uefishell
  curl -OL https://github.com/tianocore/edk2/raw/master/ShellBinPkg/UefiShell/X64/Shell.efi
