Configure NFS Client

This example is based on the environment below.
+———————-+ | +———————-+
| [ NFS Server ] |10.0.0.30 | 10.0.0.31| [ NFS Client ] |
| techhades.in + |——————+++|www.techhades.com |
| | | |
+———————-+ +———————-+

[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 = techhades.i
[root@www ~]# systemctl start rpcbind
[root@www ~]# systemctl enable rpcbind
[root@www ~]# mount -t techhades.in:/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
tmpfs tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs tmpfs 1.9G 8.3M 1.9G 1% /run
tmpfs tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup
/dev/vda1 xfs 497M 219M 278M 45% /boot
dlp.srv.world:/home nfs4 46G 1.4G 45G 4% /home
# /home 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/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
techhades.in:/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 techhades.in:/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

[root@www mntdir]# cat /proc/mounts | grep mntdir
/etc/auto.mount /mntdir autofs rw,relatime,fd=18,pgrp=2093,timeout=300,minproto=5,maxproto=5,direct 0 0
dlp.srv.world:/home /mntdir nfs4 rw,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,
