Known to work on Slackware 14 & 14.1
Assumptions
1) This HOWTO assumes that you are using a vanilla install of Slackware and have not changed the default HOSTS_ALLOW, HOSTS_DENY, or firewall rules.
2) For this example, the shared directory on the server will be /nfs_share
3) For this example, the mount point of the NFS share will be /mnt/nfs_share
4) We want anyone on our subnet (192.168.1.x) to have RW access the share
Overview
1) Setup the server
2) Setup the client
3) Mount the NFS directories on the client
Server Setup
Add the NFS shares to the /etc/exports file
vi /etc/exports
add:
/nfs_share 192.168.1.1/24(rw,sync,no_subtree_check)
Start the NFS and RPC daemons
chmod 755 /etc/rc.d/rc.nfsd chmod 755 /etc/rc.d/rc.rpc /etc/rc.d/rc.nfsd start /etc/rc.d/rpc start
Export the shares
exportfs -a
Check to see if the shares are being shared
exportfs
Client Setup
Create the mount point
mkdir /mnt/nfs_share
Mounting
On the CLIENT machine, you have 3 options here: manually mounting, auto-mount at boot, or semi-auto mount
MANUALLY MOUNT
mount my.nfs.server:/nfs_share /mnt/nfs_share
AUTO-MOUNT AT BOOT
Add the mount command to /etc/fstab
vi /etc/fstab
add:
my.nfs.server:/nfs_share /mnt/nfs_share nfs rw,defaults 0 0
SEMI-AUTO-MOUNT
Add the mount command to /etc/fstab
vi /etc/fstab
add:
my.nfs.server:/nfs_share /mnt/nfs_share nfs rw,noauto 0 0
then when you want to mount, just run:
mount /mnt/nfs_share
NOTE ABOUT AUTO_MOUNTING
If you mount at boot and the server machine is unavailable, it will cause your client machine to take a long time to boot as the NFS client will make multiple attempts to connect and you will have to wait for it to time-out for each attampt.
For The Impatient
All the steps with no explanation:
SERVER:
echo "/SHARED_DIR YOUR_SUBNET/24(rw,sync,no_subtree_check)" >> /etc/exports chmod 755 /etc/rc.d/rc.nfsd chmod 755 /etc/rc.d/rc.rpc /etc/rc.d/rc.nfsd start /etc/rc.d/rpc start exportfs -a
CLIENT:
mkdir /mnt/nfs_share echo "YOUR_NFS_SERVER:/SHARED_DIR /CLIENT_MOUNT_POINT nfs rw,defaults 0 0" >> /etc/fstab mount /CLIENT_MOUNT_POINT
Problems/Solutions
PROBLEM: NFS shares won't mount on client box with a “Stale NFS file handle” error.
SOLUTION:
1) Forcibly unmount the directory on the CLIENT machine (if mounted): <code>umount -f /mnt/nfs_share</code> 2) Flush the NFS registry on the SERVER machine: <code>exportfs -f</code> 3) Remount the NFS share
