NFS Export Setup Guide for Red Hat and CentOS EC2

This guide covers the steps to set up NFS export to share a directory from a Red Hat or CentOS server running on EC2.

Steps

  1. Start a Red Hat or CentOS EC2 instance and check the security group to make sure that the NFS port on this server is open for connection from your NFS client servers.

  2. Install NFS server.

    $ sudo yum install nfs-utils

  3. Mount your objectivefs filesystem (e.g. on /ofs).

    $ sudo mount.objectivefs <your filesystem> /ofs

  4. In /etc/exports, add the following line where directory is the directory you would like to share and ip address is the ip address of the NFS client machines.

    <directory> <ip addr>(rw,fsid=<unique id>,no_subtree_check,mp,async)
    Example to allow the NFS client at 10.0.0.100 to mount /ofs:
    /ofs  10.0.0.100(rw,fsid=222,no_subtree_check,mp,async)

  5. In /etc/sysconfig/nfs, increase the number of threads on the NFS server.

    RPCNFSDCOUNT=<number of threads>  # e.g. 64

  6. Restart the service.

    $ sudo /etc/init.d/nfs restart
    OR
    $ sudo service nfs restart
