+----------------------+          |          +----------------------+
| [    NFS Server    ] |10.0.0.30 | 10.0.0.31| [    NFS Client    ] |
|     dlp.srv.world    +----------+----------+     www.srv.world    |
|                      |                     |                      |

[1] Configure NFS Client.
[root@www ~]#
yum -y install nfs-utils
[root@www ~]#
vi /etc/idmapd.conf
# line 5: uncomment and change to your domain name

Domain =
srv.world
[root@www ~]#
systemctl restart rpcbind

[root@www ~]#
systemctl enable rpcbind

[root@www ~]#
mount -t nfs dlp.srv.world:/home /home

[root@www ~]#
df -hT

# home directory from NFS server is mounted
[2] Configure NFS mounting on fstab to mount it when the system boots.
[root@www ~]#
vi /etc/fstab 
/dev/mapper/fedora--server-root /                  ext4  defaults 1 1
UUID=1dfd504b-a288-4e1e-bfdc-9241e3b4bb6c /boot    ext4  defaults 1 2
/dev/mapper/fedora--server-swap swap               swap  defaults 0 0
# add at the lat line: change home directory this server mounts to the one on NFS

dlp.srv.world:/home /home                       nfs   defaults 0 0
[3] Configure auto-mounting.
For example, set NFS directory on /mntdir.
[root@www ~]#
yum -y install autofs
[root@www ~]#
vi /etc/auto.master
# add follows to the end

/-    /etc/auto.mount
[root@www ~]#
vi /etc/auto.mount
# create new : [mount point] [option] [location]

/mntdir -fstype=nfs,rw  dlp.srv.world:/home
[root@www ~]#
mkdir /mntdir

[root@www ~]#
systemctl start autofs

[root@www ~]#
systemctl enable autofs

# move to the mount point to make sure it normally mounted

[root@www ~]#
cd /mntdir

[root@www mntdir]#
ll
