Linux NFS Server Configuration

What is NFS Server

The Network File System (NFS) was developed to allow machines to mount a disk partition on a remote machine as if it were a local disk. It allows for fast, seamless sharing of files across a network

How to Configure NFSServer in Linux

#There is two way to configure NFS Server.
#Using NFS Server COnfiguration Tool (System-Config-NFS)
#manually Editing Configuration File vi /etc/exportfs
NFS Server Configuration Tool

#root@locathost#system-config-nfs

#Directory — Specify the directory to share, such as /tmp.
#Host(s) — Specify the host(s) with which to share the directory.(bglinux or 138.239.197.10 or * to give everyone access)
#Basic permissions — Specify whether the directory should have read-only or read/write permissions.

#General tab->click checkbox Sync write operations on request

Manually Editing NFS Server Configuration File vi /etc/exportfs

#root@localhost#vi /etc/exportfs
#root@localhost# /work *(ro,sync) (edit or delete and !wq save file)
#root@localhost#exportfs -a (reflect changes in NFS Server
Linux NFS configuration services

#root@localhost#etc/rc.d/init.d/portmap start
#root@localhost#/etc/rc.d/init.d/nfslock start
#root@localhost#/etc/rc.d/init.d/nfs start

Verify NFS Server is Running

#root@localhost#rpcinfo -p
