PXE boot VM

  • The ROCs and VTPs are booted using PXEboot. The PXEboot is hosted in a virtual machine located at the Hall ESX clusters. The VM name is "cdaqpxe.jlab.org"

Set up the PXE boot

  • Install required packages: yum install nfs-utils tftp-server syslinux-tftpboot syslinux
  • Enable tftp as root: (an explanation about tftp.service and tftp.socket: [1])
systemctl enable tftp.socket
systemctl start tftp.socket
  • Create PXE boot directory:
cd /tftpboot
mkdir linux-diskless
  • Set up PXE boot configurations
cd /tftpboot/linux-diskless
cp /usr/share/syslinux/pxelinux.0 . (This turns out not working. Instead, do: scp root@cdaqfs1:/tftpboot/linux-diskless/pxelinux.0 )
scp -r root@cdaqfs1:/tftpboot/linux-diskless/pxelinux.cfg .
  • Copy boot images from cdaqfs1 to /tftpboot/linux-diskless/:
scp -r root@cdaqfs1:/tftpboot/linux-diskless/boot .
  • Edit tftp systemd configuration file to let the tftp directory point to the /tftpboot:
vi /usr/lib/systemd/system/tftp.service

and change: 

ExecStart=/usr/sbin/in.tftpd -s /tftpboot
