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
