Use the mount command to mount an NFS filesystem
from another machine:
mkdir /mnt/local # Only required if /mnt/local doesn't exist
mount bigdog:/mnt/export /mnt/local
|
In this command, bigdog is the hostname of the NFS fileserver,
/mnt/export is the filesystem that bigdog is
exporting, and /mnt/local is a directory on the
local machine where we want to mount the filesystem. After the
mount command runs (and if we have the proper
permissions from bigdog) we can enter ls
/mnt/local and get a listing of the files in
/mnt/export on bigdog.
The file that controls what filesystems you wish to export is
/etc/exports. Its format is:
directory hostname(options)
|
the
(options) are
discretionary. For example:
/mnt/export speedy.redhat.com
|
would allow speedy.redhat.com to mount
/mnt/export, but:
/mnt/export speedy.redhat.com(ro)
|
would just allow speedy to mount
/mnt/export
read-only.
Each time you change /etc/exports, you must tell
the NFS daemons to examine it for new information. One simple way to
accomplish this is to just stop and start the daemons:
/etc/rc.d/init.d/nfs stop
/etc/rc.d/init.d/nfs start
|
Or you can restart the daemons with this command:
/etc/rc.d/init.d/nfs restart
|
The following will also work:
killall -HUP rpc.nfsd rpc.mountd
|
See the following man pages for more details: nfsd(8), mountd(8), and
exports(5). Another good reference is Managing NFS and NIS
Services, by Hal Stern, published by O'Reilly &
Associates.
