I'm trying to setup NFS so that a linux user (non-root) can mount a directory of another machine(server) with read/write permissions.

Let say, I have a directory named "storage" on server(192.168.50.100) which will be exported and a host with IP address 192.168.50.60 should mount that directory in a local linux user account.

The details I used,

On server machine (/etc/exports)
/storage 192.168.50.60(rw,sync)

On host (/etc/fstab)
192.168.50.100:/storage /demo nfs defaults 0 1

[admin@suraj demo]# mount 192.168.50.100:/storage .
mount: only root can do that

So, I tried to login with root
[root@suraj demo]# mount 192.168.50.100:/storage .

>> directory is mounted. And I re-login into "admin" user account to create a file. But it says read-only.

[admin@suraj demo]# vi hello
[readonly]

I'm able to mount and edit files if I'm mounting in "root" account. But unable to mount in "admin" linux user account and perform read/write/execute operations. Can someone help me how to edit configurations to mount and have read-write permissions for local linux user instead of root.

Hello and welcome to LinuxQuestions,

If you want a user to be able to mount a partition/share to a mountpoint you'll need to add the user parameter to the mountpoint in /etc/fstab. Have a look at
Next, check the permissions on the directory where you're mounting the NFS share. And on the NFS server side add
to the export in /etc/exports (read man page for details), then run
and try again. Let us know if you encounter errors.

Looking forward to your participation in the forums. Have fun with Linux.

Kind regards,

Eric

Thanks Eric for the reply.

On the server there will be no user called "admin" and I'm creating "storage" folder in "/". So, its permissions are uid=root and gid=root.Now, from client machine when I log in as root and create a mount point folder called "demo", it has permissions uid=root and gid=root and I feel this is the reason, it allows me to mount and create files in mount directory. But how do I achieve the same with local linux user say "admin" ? Even if I create a folder "demo" in admin userspace, initially its permissions are uid=admin and gid=admin. And now when I try to mount it says "only root can do mount". So, I did sudo su and then mounted the directory to my mountpoint and now the "demo" permissions changed to uid=root and gid="root" and gives me "readonly" when I switch back to "admin" space.

I have tried giving
In /etc/exports:
/storage 192.168.50.100(rw,sync,no_subtree_check,no_root_squash)
> exportfs -a

On client (/etc/fstab):
192.168.50.60:/storage /home/admin/demo nfs defaults,user 0 1

Still I can't do mount from "admin" account.

Hi
as far i know any nfs mounted its inherited permission from the server, you may need to check what permission on the server side.
and also you you can solve you problem with autofs by using autofs no need for the any users to use mount and it simply it available on demand
