Answer 1

On the server, edit the file <tt>/etc/exports</tt> to list the directories you
want NFS to offer, and to which systems they should be offered:
/u01    *(rw,sync,no_root_squash)
/u02    *(rw,sync,no_root_squash)
/u03    *(rw,sync,no_root_squash)The <tt>*</tt> matches any system/network and the <tt>(rw)</tt> says let the
other systems read and write the tree, the <tt>sync</tt> forces the server NFS
to finish the I/O before telling the clients the I/O is done, and the optional
<tt>no_root_squash</tt> lets root on a client system access the files as if
they were root on the NFS server; this may not be what you want.
# /sbin/chkconfig nfs on
# /sbin/service nfs startOn the NFS client, edit the <tt>/etc/fstab</tt> file to have lines that look
like this:
myserver:/u01 /u01 nfs rw,rsize=32768,wsize=32768,sync,nointr,hard 0 0
myserver:/u02 /u02 nfs rw,rsize=32768,wsize=32768,sync,nointr,hard 0 0
myserver:/u03 /u03 nfs rw,rsize=32768,wsize=32768,sync,nointr,hard 0 0and then from the client make sure you can see the offered files:
# /usr/sbin/showmount -e myserverand if you can, do this on the client:
# mkdir /u01 /u02 /u03
# mount /u01
# mount /u02
# mount /u03If the clients ever reboot, the NFS files will be mounted automatically and you
will not need these last 3 commands.
The RDBMS has its own requirements for the options in the <tt>/etc/fstab</tt>
entry, so the <tt>rw,rsize=...</tt> example may need to be adjusted a little.
Happy NFS'ing.
