Estou seguindo o este guia . Eu sou completamente novo no Ubuntu, trabalhando em 14.04 LTS.
Quando chego ao último passo antes de lidar com o Kerrighed (na metade do tutorial), tento iniciar meu servidor DHCP, mas ele falha.
root@MASTER:~# /etc/init.d/tftpd-hpa restart
root@MASTER:~# /etc/init.d/isc-dhcp-server restart
* Stopping ISC DHCP server dhcpd [fail]
* Starting ISC DHCP server dhcpd * check syslog for diagnostics.
[fail]
root@MASTER:~# /etc/init.d/nfs-kernel-server restart

Aqui está o que eu tenho no syslog digitando dmesg:

Aqui está o /etc/dhcp/dhcp.config:
# General options
option dhcp-max-message-size 2048;
use-host-decl-names on;
deny unknown-clients; # This will stop any non-node machines from appearing on the cluster network.
deny bootp;

option domain-name "kerrighed"; # Just an example name - call it whatever you want.
option domain-name-servers 192.168.1.1; # The server's IP address, manually configured earlier.
# Information about the network setup
subnet 192.168.1.0 netmask 255.255.255.0 {

Aqui está etc / network / interfaces:

# The primary network interface, manually configured to protect NFS:

netmask 255.255.255.0
O computador escravo conectado (para o clustering) diz PXE-E51 : No DHCP or proxyDHCP offers were received . Portanto, parece que o servidor DHCP definitivamente não está em execução. O Tftpd não dá nenhuma resposta quando eu reinicio no terminal e o nfs parece bom.
Eu verifico:
- > / etc / default / isc-dhcp-server contém INTERFACES="eth0"?
- > Certifique-se de usar o /etc/dhcp3/dhcpd.conf, e não o /etc/dhcp/dhcp.config (já que está usando o isc-dhcp-server)
- > Defina o grupo e seu host contido na sub-rede {} declaração
