NFS Server/Client configuration on Linux

Install NFS packages:

yum install nfs-utils libnfsidmap

Once the packages are installed, enable and start NFS services:

systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind
systemctl start nfs-server
systemctl start rpc-statd
systemctl start nfs-idmapd

Create NFS share directory:

mkdir /share
touch /share/{a,b,c}
echo test message > /share/test

Export share:

cat /etc/exports
/share 192.168.122.191(rw,sync,no_root_squash)

exportfs -rv

On client side:

Install client package:
yum install nfs-utils rpcbind

Start rpcbind service:

systemctl start rpcbind

Show mount from NFS server:

showmount -e 192.168.122.107
Export list for 192.168.122.107:
/share 192.168.122.191

Mount NFS share:

mkdir /mnt/share
mount 192.168.122.107:/share /mnt/share/
df -ah
ls -la /mnt/share/
touch /mnt/share/d

To umount it, use umount command.
