To export a directory with NFS

In order to export or share directory called /data2, you need to edit a file called /etc/exports. The file /etc/exports serves as the access control list for file systems which may be exported to NFS clients.:
# vi /etc/exports
Add config directive as follows:
/data2 *(rw,sync)

Each line contains an export point and a whitespace-separated list of clients allowed to mount the file system at that point. Each listed client may be immediately followed by a parenthesized, comma-separated list of export options for that client.

Where,

* rw - Allow both read and write requests on /data2 NFS volume
* sync - Reply to requests only after the changes have been committed to stable storage

Save and close the file. Restart the nfs service:
# /etc/init.d/nfs restart
NFS client configuration

Client computer need to mount file system using mount command or /etc/fstab file, enter:
# mkdir /mnt/nfs
# mount -t nfs4 nfsserver-name-or-ip:/data2 /mnt/nfs
