NFS:  Provide Network shares to specific Clients

(I am using NFS server and NFS clients for this context, but actually no NFS server exists, the server which is sharing NFS files assumed as NFS server and the clients or servers which are accessing those NFS files are assumed as NFS clients)

On the NFS server Side (server IP 192.168.2.250)

Install necessary packages,

#yum install nfs-utils rpcbind

#/etc/init.d/nfs start

#/etc/init.d/rpcbind start

Create NFS shares:

Edit file /etc/exportfs

Inside /etc/exportfs add the mount point and share permissions,

#nano /etc/exportfs

#add the shares

(Important: Do not use no_root_squash when creating shares)

Ex.

/test      192.168.0.0/24(rw,sync)

#this create share with Read Write permission and this can be accessible by all clients in 192.168.0.0/24 subnet.  

/test      192.168.0.217(rw,sync) # NFS share only to client 192.168.0.217

 /test     192.168.0.0/24(ro) #Read only across the subnet

Save and close the file.

Restart NFS services on the server side.

On the client end:

Install packages to access NFS shares (Install client for NFS)

#yum install portmap nfs-common

#add NFS server to /etc/hosts

Mount NFS shares as,

#mount 192.168.2.250:/test /mnt/test

For permanent mount edit fstab,

#nano /etc/fstab

Add these lines,

192.168.0.2.250:/test /mnt/test nfs defaults 0 0
