192.168.1.2 node2.example.com    node2

 in NFS Machine

mkdir /data

vi /etc/exports

/data node1.example.com(rw,no_root_squash) node2.example.com(rw,no_root_squash)

 In both node1 and node2

vi /etc/fstab

add

 nfs.example.com:/data       /data nfs rw 0 0

 In both machines  add

192.168.37.125 nfs.example.com      nfs

in /etc/hosts

 vi /etc/apache2/sites-available/default

 Change default DocumentRoot in line 5, Inplace of  /var/www  add  /data
