Configure NFS server and Configure NFS client - Network File System

   NFS offers service which can use the file which other remote hosts have as well as the file which a local host has.  Portmapper should should be install and configure in order to start NFS service.  The article below show the step by step NFS installation, the NFS server configuration and NFS client configuration.

Installation of NFS server

[root@tenouk ~]# mount /dev/cdrom

[root@tenouk ~]# cd /mnt/cdrom/RedHat/RPMS

[root@tenouk ~]# rpm –Uhv nfs-utils-0.3.1-13.i386.rpm

[root@tenouk ~]# cd /

[root@tenouk ~]# umount /dev/cdrom

Start and stop NFS service

[root@tenouk ~]# /sbin/service nfs start

[root@tenouk ~]# /sbin/service nfs stop

Setting of automatic start for NFS

Set automatically start for nfs on runlevel 3 and runlevel 5.

[root@tenouk ~]# /sbin/chkconfig –level 35 nfs on

Confirmation of automatic start

[root@tenouk ~]# /sbin/chkconfig --list nfs

nfs 0:off 1: off 2: off 3: on 4: off 5:on 6: off

[root@tenouk ~]#

Configure /etc/exports

File which sets which file or directory on NFS server other hosts can share

It is called export to put out permission to other hosts.

[root@tenouk ~]# vi /etc/exports

/home 10.10.0.0/255.255.0.0(rw)

The NFS mount is permitted to be done to the host who has belonged to 10.10.0.0/255.255.0.0 while possible to be read and written.

Configure /usr/sbin/exportfs

The content written in /etc/exports is moved to the export table.

[root@tenouk ~]# /usr/sbin/exportfs –a

All content written in /etc/exports is made effective.

[root@tenouk ~]# /usr/sbin/exportfs –v

The content of a present export table is displayed.

Confirmation of NFS mount

Which client does the NFS mount is confirmed.

[root@tenouk ~]# showmount

Host on localhost

192.168.0.199

[root@tenouk ~]#

Display the NFS mount directory.

[root@tenouk ~]# showmount –d

/home

/export

[root@tenouk ~]#

The directory and the client that the NFS mount is done are displayed.

[root@tenouk ~]# showmount –a

hostA:/home

192.168.0.2:/export

192.168.0.3:/export

[root@tenouk ~]#

Setting of NFS client

[root@tenouk ~]# mount –t nfs compaq:/export /mnt/nfs

(type)

Directory /export on NFS server compaq is done and the NFS mount is done to local host's /mnt/nfs.

Un mount NFS.

[root@tenouk ~]# umount /mnt/nfs

Automatic mount NFS filesystem

When starting, the mount is done when the NFS mount is described in /etc/fstab.

[root@tenouk ~]# vi /etc/fstab

hostA:/export /mnt/nfs mfs soft 0 0

The first field : Directory name on NFS server

The second field : Mount point on local host

The third field : Kind of filesystem

The fourth field : Mount option

The fifth field :

The sixth field :

Automount NFS

Installation of autofs is needed to make sure that the NFS is aoutmatically mount.

Confirmation on autofs installation.

[root@tenouk ~]# rpm -q autofs 

Installation of autofs.

Install autofs using rpm package.

[root@tenouk ~]# mount /dev/cdrom

[root@tenouk ~]# cd /mnt/cdrom/RedHat/RPMS

[root@tenouk ~]# rpm -Uhv autofs-3.1.7-28.i386.rpm

[root@tenouk ~]# cd /

[root@tenouk ~]# umont /dev/cdrom

Start, stop and restart autofs.

[root@tenouk ~]# /sbin/service autofs start

[root@tenouk ~]# /sbin/service autofs stop

[root@tenouk ~]# /sbin/service autofs restart

Setting of autofs automatic start.

[root@tenouk ~]# /sbin/chkconfig --level 35 autofs on

Confirmation of autofs automatic start

[root@tenouk ~]# /sbin/chkconfig --list autofs

Setting which uses NIS

The configuration on the NIS server

[root@tenouk ~]# vi /etc/auto.master

/nfs /etc/auto.home --timeout 60

[root@tenouk ~]# vi /etc/auto.home

home -rw,hard,intr,nolock compaq:/home

[root@tenouk ~]# vi /var/yp/Makefile

all: passwd group hosts rpc services netid protocols mail \

shadow auto.home \

# netgrp shadow publickey networks ethers bootparams printcap \

# amd.home auto.master auto.home auto.local passwd.adjunct \

# timezone locale netmasks

Update of NIS data base

[root@tenouk ~]# cd /var/yp

[root@tenouk ~]# make

Setting on the NIS / NFS client side

Confirmation of auto.home

[root@tenouk ~]# ypcat auto.home

-rw,hard,intr,nolock compaq:/home

[root@tenouk ~]# vi /etc/auto.master

/nfs auto.home --timeout 60
