Hello,
Follow below configuration steps -

ssh natasha@ststor01
sudo su
systemctl enable nfs-server
chkconfig nfs-server on
systemctl enable rpcbind
chkconfig rpcbind on
systemctl start nfs-server
systemctl status nfs-server
systemctl start rpcbind
systemctl status rpcbind
vi /etc/exports
/web 172.16.238.10(rw,sync,no_root_squash)
/web 172.16.238.11(rw,sync,no_root_squash)
/web 172.16.238.12(rw,sync,no_root_squash)
exportfs -a
showmount -e ststor01
On all 3 nfs client i.e., app servers
mount -t nfs ststor01:/web /var/www/html
echo 1 >>/var/www/html/file.txt
