Quick NFS HOWTO for Centos

On the server

vi /etc/exports
add lines like:
/data1/sessions 192.168.0.0/255.255.0.0(rw) 10.0.0.0/255.0.0.0(rw)
vi /etc/hosts.allow
add lines like:
portmap: 192.168.0.0/255.255.0.0, 10.0.0.0/255.0.0.0
/etc/init.d/nfsd start

On the Client

vi /etc/fstab, adding the following line:
nfshostname:/data1/sessions /mnt nfs rw,hard,intr 0 0
make sure to mkdir /mnt/sessions, or it won’t work. To do it manually, just:
mount nfshostname:/data1/sessions /mnt/sessions
