NFS – quick win

This is a very basic step-by-step guide to create a CentOS7 NFS server that shares a folder /nfsshare over 192.168.4.0/24 network. This share will be owned by apache and mountable on a CentOS web server.

Here the instructions how to create the server and how to setup the client.

NFS Server

Add this line in IPTABLES:

 

Run the following to create a share folder and setup NFS:

 

NFS Client

e.g. assuming that NFS server’s IP is 192.168.4.1

Add this line in IPTABLES:

Then, run this:

NOTE: we are hardly mapping the NFS server’s IP in /etc/hosts to make easier to recognise the mount (in case of multiple mounts).

If you are facing the issue where you mount /nfsshare and you see the owner of the files and folders showing as nobody:nobody, it could be related to rpcidmapd and DNS. To fix this, try to update /etc/hosts on the Client with <hostname>.nfsdomain.loc

Disable firewalld – Centos 7

Install iptables and remove firewalld
