Configure services

Start (and keep it started after a reboot) “rpcbind” :

[root@nfs ~]# systemctl start rpcbind && systemctl enable rpcbind

Start (and keep it started after a reboot) NFS server :

[root@nfs ~]# systemctl start nfs-server && systemctl enable nfs-server
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.

Configure firewalld

Open services :

[root@nfs ~]# firewall-cmd --permanent --add-service=nfs --add-service=rpc-bind --add-service=mountd

Activate the configuration :

[root@nfs ~]# firewall-cmd --reload

Export filsystems

Add mount point to export in “/etc/exports” :

[root@nfs ~]# cat /etc/exports
# Here is an simple example :

And export defined mount points :

[root@nfs ~]# exportfs -av

This mount point is now exported :

[root@nfs ~]# showmount -e
Export list for nfs:

On NFS client side

We can mount this export filesystem :

[root@client ~]# mount /mnt

Because our I.P. address is authorized :

[root@client ~]# ip addr show dev eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether f6:2f:e3:7f:8a:26 brd ff:ff:ff:ff:ff:ff
    inet brd scope global eth1
       valid_lft forever preferred_lft forever
    inet6 fe80::f42f:e3ff:fe7f:8a26/64 scope link
       valid_lft forever preferred_lft forever
