CentOS NFS How-to Guide: Exporting and Mounting a NFS Drive

with one comment

This guide shows you how to start an NFS service on one (host) machine, export the NFS drive, and then connect to that NFS drive from a client machine.

## On the NFS host machine:

#Start Portmap service if needed.
#NFS uses portmap and a bunch of ports (that you can set in /etc/sysconfig/nfs) if you want.
See this link for more details on NFS ports.

#Start portmap service

service portmap status
service portmap start (if needed)

#Start NFS

service nfs start

#Edit /etc/exports
#Reference: https://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/ref-guide/s1-nfs-server-export.html

Format is (select the options you want):
[Directory to export] [Hosts to allow](options)

/home/just_testing 192.168.0.0/24(rw,async,wdelay,root_squash)

#Run exportfs to refresh NFS exports

exportfs -av

Be sure the proper ports are open on iptables
Reference: http://pario.no/2008/01/15/allow-nfs-through-iptables-on-a-redhat-system/

## Now on your NFS client machine:
Start portmap

service portmap start

Create a mount point and mount the NFS drive. Remember to use your own server’s IP address:

mkdir /mnt/nfs-usbdisk
mount 192.168.0.2:/home/just_testing /mnt/nfs-usbdisk

Voila ! Tail your logs if you have any problems !
