$ cat /etc/exports
/home *(rw,no_root_squash)

$ exportfs -r

Allow NFS in firewall

$ firewall-cmd --add-service=nfs --permanent
$ firewall-cmd --permanent --add-service=rpc-bind
$ firewall-cmd --permanent --add-service=nfs
$ firewall-cmd --permanent --add-service=mountd
$ firewall-cmd --reload

Checking NFS from server

$ showmount -e localhost
Export list for localhost:
/home *

Mounting the share on client

$ sudo mount -t nfs 192.168.15.15:/home /mnt
$ echo $?
0

Check /etc/mtab for NFS mount point:

192.168.15.15:/home /mnt nfs rw,vers=4,addr=192.168.15.15,clientaddr=192.168.0.48 0 0
