[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 start rpcbind

[root@www ~]#
systemctl enable rpcbind

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

[root@www ~]#
df -hT 

Filesystem              Type      Size  Used Avail Use% Mounted on
/dev/mapper/centos-root xfs        46G  1.4G   45G   4% /
devtmpfs                devtmpfs  1.9G     0  1.9G   0% /dev

dlp.srv.world:/home  nfs4       46G  1.4G   45G   4% /home
# /home from NFS server is mounted
# if you'd like to mount with NFSv3, add '-o vers=3' option

[root@www ~]#
mount -t nfs -o vers=3 dlp.srv.world:/home /home
[2] Configure NFS mounting on fstab to mount it when the system boots.
[root@www ~]#
vi /etc/fstab 
/dev/mapper/centos-root /                       xfs     defaults        1 1
UUID=a18716b4-cd67-4aec-af91-51be7bce2a0b /boot xfs     defaults        1 2
/dev/mapper/centos-swap swap                    swap    defaults        0 0
# add like follows to the end

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
