In some cases (such as no installed CD-ROM or no physical access to the servers) we need to install Fuel Master node somehow other way from CD or USB Flash drive. Starting from Fuel 4.0 it’s possible to deploy Master node with PXE
The process of deployment of Fuel master node over network consists of booting linux kernel by DHCP and PXE. Then anaconda installer will download configuration file and all packages needed to complete the installation.
You will need to setup NFS server on your install system. Edit the NFS exports file:
# vim /etc/exports
Add the following line:
And restart it:
# /etc/init.d/nfs-kernel-server restart
Now we need to write the pxelinux configuration file. It will be located here /var/lib/tftpboot/pxelinux.cfg/default:
LABEL Fuel for OpenStack version 8.0 ISO KERNEL /commons/openstack/fuel.openstack.v8.0/isolinux/vmlinuz INITRD /commons/openstack/fuel.openstack.v8.0/isolinux/initrd.img APPEND biosdevname=0 ks=nfs:10.12.112.6:/srv/tftp/commons/openstack/fuel.openstack.v8.0/ks.cfg repo=nfs:10.12.112.6:/srv/tftp/commons/openstack/fuel.openstack.v8.0 ip=dhcp
Now we need to unpack the Fuel ISO file we have downloaded:
mkdir -p /var/lib/tftpboot/commons/openstack/fuel.openstack.v8.0 /mnt/fueliso mount -o loop /path/to/your/fuel.iso /mnt/fueliso rsync -a /mnt/fueliso/ /var/lib/tftpboot/commons/openstack/fuel.openstack.v8.0 umount /mnt/fueliso && rmdir /mnt/fueliso
So that’s it! We can boot over the network from this PXE server.
