How to create an NFS Server and mount a share to another Linux server

How to create an NFS Server and mount a share at another Linux server.

How to create an NFS Server to export or share a directory:

1. YaST --> Network Services --> NFS Server, select Start.
2. Click Next.
3. Select Add Directory, provide the local directory path to export, and click OK.
4. A box will come up for configuring the export options for that path.  "Host Wild Card" is used to define what NFS client hosts will be allowed to mount.  This will default to "*" (any client) but can be changed to limited allowed clients, based on hostnames, ip addresses, subnets, netgroups, etc.  See "man exports" for more details.
5. The export options for the defined client hosts will usually need to be changed, based on administrative preferences and security needs.  Frequently it is desired to replace ro (read-only) with rw (read-write) and replace root_squash with no_root_squash, to allow the client's root user to be treated as a true root user on the NFS share.  Otherwise the client's root user is "squashed" and treated like "nobody".
6. Click OK and then click Finish.
   
   

How to mount an NFS Share at a Linux client host.  Select from the following options:

• (option 1) To setup permanent mounts within YaST:
• YaST --> Network Services --> NFS Client --> Add.
• Provide the NFS Server Hostname or Network Address.
• For Remote Directory click Select.  Choose a path and click OK.
• Provide a Mount point (local directory).
• For Options, the defaults are usually okay, but other mount options can be added there.
• Click OK and OK.
• (option 2) To temporarily mount, from a terminal window (one-time mount):
  mount <hostServer>:/share <localMountPoint>
  Note: The local mount point directory must already be created.
• (option 3) To create a permanent (at boot) mount manually (without yast), edit /etc/fstab and add the following line in:
  <hostServer>:/<share> <localMountPoint>    nfs     defaults 0 0
  Note: Replace <hostServer> with the NFS Server name or IP address, replace <share> with the path which has been exported from the NFS Server, and replace <localMountpoint> with a local path which already exists.  If you wish to change the default mount options, replace the word "defaults" with whatever options are desired.
