Cluster Beowulf
Configuração do Cluster Beowulf no Debian 7.
Parte 6: PVSF2
Instalando PVFS2 (servidor e nós).
Execute a sequência de comandos no servidor e nos nós:
# apt-get install libdb5.1 libdb5.1-dev
Nos nós e no servidor:
# cd /usr/src
# wget ftp://ftp.parl.clemson.edu/pub/pvfs2/pvfs-2.8.2.tar.gz
# mkdir /opt/mpich #Criando o caminho para a MPICH, mesmo sem ter instalado ela ainda
# mkdir /opt/pvfs2
# tar -xzvf pvfs-2.8.2.tar.gz
# ls
# cd pvfs-2.8.2
# ./configure --prefix=/opt/pvfs2 --enable-shared --disable-segv-backtrace --with-mpi=/opt/mpich
Deve terminar sem erros, com a linha: PVFS2 version string: 2.8.2
# make
Deverá terminar com a última linha: GENCONFIG examples/fs.conf
# make install
Depois, substituir o conteúdo dos arquivos fstab no servidor e nós (alterar os números do IP de 192.168.1.6, dentro do arquivo fstab.nopelo pelo IP do servidor).
# nano /etc/fstab
Exemplo fstab (servidor):
Exemplo fstab (nó):
Depois de salvar, execute os comandos:
# mkdir /mnt/pvfs2 #Servidor e nós
# update-rc.d -f exim4 remove #Somente nos nós
Configurando a variável de ambiente, entrar no arquivo (servidor e nós):
# nano ~/.bashrc
E acrescentar no final:
Depois, reiniciar as máquinas:
# shutdown -r now

# apt-get install libdb5.1 libdb5.1-dev
