Configure DHCP, NFS, PXE and IPMI¶

Prerequisites¶

DHCP server
PXE boot server
NFS server
ipmitool and IPMI access to baremetal1‘s BMC

Setup DHCP¶

Configure DHCP for PXE boot baremetal1 and restart dhcpd. Here’s an example of the entry on /etc/dhcpd.conf.

host baremetal1 {
  hardware ethernet aa:bb:cc:11:22:33;
  fixed-address 192.168.1.101;
  option host-name baremetal1;
  filename "pxelinux.0";
  next-server 192.168.1.1;
  server-name mgmt;
}

Note

If you have Dnsmasq instead of dhcpd, please configure it as equivalent to above.

Setup NFS¶

Set the livecd boot image on NFS.

$ mkdir /mnt/livecd
$ sudo mount -o loop /path/to/.teefaa/teefaa-debian-live.iso /mnt/livecd
$ sudo mkdir -p /nfsroot/teefaa
$ sudo cp -pr /mnt/livecd /nfsroot/teefaa/netboot

Add entry on /etc/exports to export /nfsroot/teefaa/netboot.

/nfsroot/teefaa/netboot 192.168.1.0/24(rw,async,no_subtree_check,no_root_squash)

sync exports.
```
sudo exportfs -rv
```

Setup PXE¶

Copy initrd.img and vmlinuz.

mkdir /mnt/squashfs
sudo mount -o loop /mnt/livecd/live/filesystem.squashfs /mnt/squashfs
sudo mkdir /tftproot/teefaa
sudo cp -p /mnt/squashfs/boot/initrd.img-* /tftproot/teefaa/initrd.img
sudo cp -p /mnt/squashfs/boot/vmlinuz-* /tftproot/teefaa/vmlinuz
chmod -R 777 /tftproot/teefaa

Unmount SquashFS and ISO image.
```
sudo umount /mnt/squashfs /mnt/livecd
```

Create netboot config file.

$ vi /tftpboot/pxelinux.cfg/netboot

DEFAULT teefaa
PROMPT 1
TIMEOUT 30

LABEL teefaa
  KERNEL teefaa/vmlinuz
  APPEND teefaa/initrd.img boot=live netboot=nfs nfsroot=<IP of NFS server>:/nfsroot/teefaa console=tty0 console=ttyS0,115200n8r text --

Create localboot config file.

$ vi /tftpboot/pxelinux.cfg/localboot

DEFAULT localboot
LABEL localboot
LOCALBOOT 0

Setup Teefaafile.yml¶

Comment out the config for VirtualBox and update it for Baremetal.

$ cd /path/to/Teefaa
$ vi baremetal1/Teefaafile.yml

# VirtualBox
#host_config:
#  hostname: baremetal1
#  power_driver: virtualbox
#  power_driver_config:
#    vbox_name: baremetal1_baremetal1_XXXXXXXXXX_XXXXX
#  boot_driver: virtualbox
#  boot_driver_config:
#    installer_boot: iso
#    iso_file: /path/to/Teefaa/.teefaa/teefaa-debian-live.iso

# Baremetal
host_config:
  hostname: baremetal1
  power_driver: ipmi
  power_driver_config:
    bmc_address: <bmc's ip address>
    ipmi_password: <ipmi password>
    ipmi_user: <ipmi username>
  boot_driver: pxe
  boot_driver_config:
    pxe_server: <pxe server address>
    pxe_server_user: <ssh login username>
    boot_config_file: /tftpboot/pxelinux.cfg/01-aa-bb-cc-11-22-33
    installer_boot_config_file: /tftpboot/pxelinux.cfg/netboot
    disk_boot_config_file: /tftpboot/pxelinux.cfg/localboot

Register your .teefaa/ssh_key.pub to your pxe_server_user‘s .ssh/authorized_keys on the pxe_server.

Make sure you can login with this.

ssh <ssh login username>@<pxe server address> -i .teefaa/ssh_key

Make sure you have write permission of boot_config_file.

<username>@<pxe server> ~$ ls -la /tftpboot/pxelinux.cfg/01-aa-bb-cc-11-22-33

If all is well, you should be able to provision virtual1‘s snapshot on baremetal1 with this;
```
$ cd baremetal1
$ teefaa provision
```
