Setting Up An NFS Server And Client On Fedora 13 - Page 2
4 Mounting The NFS Shares On The Client
client:
First we create the directories where we want to mount the NFS shares, e.g.:
mkdir -p /mnt/nfs/home
mkdir -p /mnt/nfs/var/nfs
Afterwards, we can mount them as follows:
mount 192.168.0.100:/home /mnt/nfs/home
mount 192.168.0.100:/var/nfs /mnt/nfs/var/nfs
You should now see the two NFS shares in the outputs of
df -h
[root@client ~]# df -h

/dev/mapper/vg_client-lv_root

[root@client ~]#
and
mount
[root@client ~]# mount
/dev/mapper/vg_client-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)

none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

192.168.0.100:/home on /mnt/nfs/home type nfs (rw,vers=4,addr=192.168.0.100,clientaddr=192.168.0.101)
192.168.0.100:/var/nfs on /mnt/nfs/var/nfs type nfs (rw,vers=4,addr=192.168.0.100,clientaddr=192.168.0.101)
[root@client ~]#
5 Testing
On the client, you can now try to create test files on the NFS shares:
client:
touch /mnt/nfs/home/test.txt
touch /mnt/nfs/var/nfs/test.txt
Now go to the server and check if you can see both test files:
server:
ls -l /home/
[root@server ~]# ls -l /home/
total 8
-rw-r--r-- 1 root root 0 Sep 16 17:44 test.txt
[root@server ~]#
ls -l /var/nfs
[root@server ~]# ls -l /var/nfs
total 0
-rw-r--r-- 1 65534 65534 0 Sep 16 19:58 test.txt
[root@server ~]#
(Please note the different ownerships of the test files: the /home NFS share gets accessed as root, therefore /home/test.txt is owned by root; the /var/nfs share gets accessed as nobody/65534, therefore /var/nfs/test.txt is owned by 65534.)
6 Mounting NFS Shares At Boot Time
Instead of mounting the NFS shares manually on the client, you could modify /etc/fstab so that the NFS shares get mounted automatically when the client boots.
client:
Open /etc/fstab and append the following lines:
vi /etc/fstab
[...] 192.168.0.100:/home /mnt/nfs/home nfs rw,sync,hard,intr 0 0 192.168.0.100:/var/nfs /mnt/nfs/var/nfs nfs rw,sync,hard,intr 0 0 |
Instead of rw,sync,hard,intr you can use different mount options. To learn more about available options, take a look at
man nfs
To test if your modified /etc/fstab is working, reboot the client:
reboot
After the reboot, you should find the two NFS shares in the outputs of
df -h
[root@client ~]# df -h
