Setup NFS Server On CentOS, RHEL

NFS, Network File System, is a server-client protocol used for sharing files between linux/unix to unix/linux systems. NFS enables you to mount a remote share locally. You can then directly access any of the files on that remote share.


On NFS Server :

# yum install nfs* -y

# service rpcbind start
# chkconfig rpcbind on
# service nfs start
# chkconfig nfs on

## Create one share directory "/backup/share"

mkdir /backup/share
chmod 755 /backup/share


## Export shared directory on NFS Server

# vim /etc/exports

/media/ivr    10.20.30.48/24(rw,sync,no_root_squash,no_all_squash)
/media/ivr    10.20.30.49/24(rw,sync,no_root_squash,no_all_squash)
:wq

# exportfs -a
# exportfs -v

## where,

/backup/share         – shared directory

10.20.30.48/24           – 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

####################################


# service nfs restart
# service rpcbind restart
# chkconfig nfs on
# chkconfig rpcbind on



###########  On NFS Client : #######################

# yum install nfs* -y

# service rpcbind start
# chkconfig rpcbind on
# service nfs start
# chkconfig nfs on


mkdir /share

### Mount the share from server to client as shown below

mount -t nfs 10.20.30.61:/media/ivr/ /media/ivr/

Note:  10.20.30.46  -  is nfs server ip and /backup/share is share folder on nfs server


For Perment Mounting on Client Side:

[root@ivr ~]# cat /etc/fstab


10.20.30.61:/media/ivr/ /media/ivr/ nfs rw,sync,hard,intr 0 0

:wq



@ reboot server and check, be carefull check all entries in fstab
