If you are a non-root regular user and attemp to mount a remote NFS share, you will get the following error:
mount: only root can do that
In order to allow a regular user without root privilege to mount a remote home directory via NFS, you can do the following.
On the NFS client host (e.g.,
/etc/fstab as root. I assume that the user requiring NFS mount is
$ sudo vi /etc/fstab
10.1.1.10:/export/alice /home/alice/Desktop/mnt nfs rw,noauto,user 0 0
In the above configuration, the
user option allows a non-root user to mount, and
noauto means no automatic mount on boot.
On the NFS server host (e.g.,
10.1.1.10), enable export for the client as root.
If you want to enable export temporarily one time (which is not persistent across reboots):
$ sudo exportfs 10.1.1.20:/export -o rw,async,no_root_squash,no_subtree_check
If you want to enable export permanently (which is persistent across reboots), edit
/etc/exports as follows.
$ sudo vi /etc/exports
Finally, run this command:
$ sudo exportfs -a
Now you can log in as
alice on the NFS client host, and do NFS mount as follows.
$ mount /home/alice/Desktop/mnt
