NFS Server side configuration
Create directory which you want to share
mkdir -p /nfsshare
yum install nfs-utils rpcbind nfs-utils-lib
chkconfig rpcbind on
chkconfig nfs on
chkconfig nfslock on
service rpcbind start
service nfs start
or
/etc/init.d/nfs start
service nfslock start
define allowed IPs on server
lets suppose
Server IP : a.a.a.a
Client IP : b.b.b.b
vi /etc/hosts.allow
mountd: 127.0.0.1 b.b.b.b
mkdir -p /nfsshare
chown -R nfsnobody.nfsnobody /nfsshare
chmod -R 750 /nfsshare
or
chown -R 65534:65534 /nfsshare
chmod -R 755 /nfsshare
vi /etc/exports
/nfsshare b.b.b.b(rw,sync,no_root_squash,no_subtree_check)
or
/nfsshare b.b.b.b/255.255.255.255(rw,sync,no_wdelay,all_squash)
exportfs -a
service nfs restart
(The no_root_squash option makes that /home will be accessed as root.) you may skip this for non root directories
NFS Client side configurations
yum install nfs-utils nfs-utils-lib
Make sure portmapper is running other wise its authenticate but give errors like this
chkconfig –list | grep portmap
To start it on centos and set it to start at boot
service portmap start
chkconfig portmap on
mkdir -p /mnt/nfsshare
mount a.a.a.a:/nfsshare /mnt/nfsshare
vi /etc/fstab
a.a.a.a:/nfsshare /mnt/nfsshare nfs rw,sync,hard,intr 0 0
df -h
mount

netstat -ntlp | grep 111 stop your firewall and disable the selinux

cat /var/log/messages|grep nfs can you try mounting using this command and make sure portmap service is running on server
mount -t nfs -v a.a.a.a:/nfsshare /mnt/nfsshare
and post the last log messages related to nfs server
cat /var/log/messages
