Cluster Beowulf
Configuração do Cluster Beowulf no Debian 7.
Parte 8: NFS
NFS:
# cd /home/kluster
No servidor:
# apt-get install portmap
# apt-get install nfs-common
# apt-get install nfs-kernel-server
# apt-get install nfs-user-server
Atualizando o kernel com as mudanças no arquivo /etc/exports (substituir o conteúdo do arquivo exports):
Exemplo exports (servidor):
Exemplo exports (nó) (alterar o numero do IP):
Executar o comando:
# exportfs -a
# cd /home/kluster
No servidor:
# apt-get install portmap
# apt-get install nfs-common
# apt-get install nfs-kernel-server
# apt-get install nfs-user-server
