NFS, is abbreviation of Network File System, is a server-client protocol used for sharing files between linux/unix to unix/linux systems. with  NFS enabled you can  mount a remote share locally. You can then  access  the data  , read   and writes  things  and thats depend  on the setup. please nore  that  NFS   share  in one the  objectifs of  RHCE  exam . and  this  tutorials  will help  you to understand  how things  works

This tutorial should work for all Redhat based  sustems  like Centos  /  Oralce Linux / and  Scientific Linux and  will explain  how to install NFS  Server and  NFS  Client

In my articles  am using  2 Centos7   servers

NFS Server Hostname: nfs-server
NFS Server IP Address:
NFS Client Hostname: nfs-client
NFS Client IP Address:

NFS Server Side Configuration

Install NFS packages in your Server system with  the following command:

yum install nfs-utils

Enable and start NFS services:

Now,  we will try  to share some directories

Create a folder named ‘/var/nfs_share’ in server and lets the client users to read and write files in that directory.

Export shared directory on NFS Server:

Edit file /etc/exports,

vi /etc/exports
Add the following line:


/var/nfs_share – shared directory – IP address range of clients
rw – Writable permission to shared folder
sync – Synchronize shared directory
no_root_squash – Enable root privilege
no_all_squash – Enable user’s authority

Allow  NFS  ports  on Firewall 

On server side If you don’t know which ports to allow through firewall, run the following command:

rpcinfo -p
Sample output:

You should allow the above ports.

To do that, go to the NFS server, and run the following commands:


Restart firewalld service to take effect the changes:

Restart the NFS service:

NFS Client Side Configuration

Install NFS packages in your client system by using the following command:

yum install nfs-utils nfs-utils-lib
Enable and start NFS services:

Create  a local founder  and  mount   NFS   share   on it

Show what is shared in remote host 

Mount the share from server to client as shown below

results :

Verify the share from the server is mounted or not using ‘mount’ command.

Sample output:

Auto mount NFS Shares

To mount the shares automatically instead of mounting them manually on every reboot, add the following lines shown in bold in the ‘/etc/fstab’ file of your client system.

vi /etc/fstab


Reboot  and Enjoy

Thats it. Now NFS server is ready to use.
