Setting Up the NFS Client


Step One—Download the Required Software

Start off by using apt-get to install the nfs programs. 
apt-get install nfs-common portmap

Step Two—Mount the Directories

Once the programs have been downloaded to the the client server, create the directories that will contain the NFS shared files 
mkdir -p /mnt/nfs/fs-01.sda1


mkdir -p /mnt/nfs/fs-01.sdb1

prevent accedent writes:

sudo chmod 000 /mnt/nfs/fs-01.sda1

sudo chmod 000 /mnt/nfs/fs-01.sdb1 

sudo mount fileshare-01:/mnt/local/sda1/ /mnt/nfs/fs-01.sda1/




You can use the df -h command to check that the directories have been mounted. You will see them last on the list.



df -h

Additionally, use the mount command to see the entire list of mounted file systems.

mount




Your list should look something like this:

/dev/sda on / type ext4 (rw,errors=remount-ro,barrier=0) [DOROOT]proc on /proc type proc (rw,noexec,nosuid,nodev)sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)none on /sys/fs/fuse/connections type fusectl (rw)none on /sys/kernel/debug type debugfs (rw)none on /sys/kernel/security type securityfs (rw)udev on /dev type devtmpfs (rw,mode=0755)devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)none on /run/shm type tmpfs (rw,nosuid,nodev)rpc_pipefs on /run/rpc_pipefs type rpc_pipefs (rw)fileshare-01:/home on /mnt/nfs/home type nfs (rw,vers=4,addr= fileshare-01,clientaddr=192.168.1.xxx)fileshare-01:/var/nfs on /mnt/nfs/var/nfs type nfs (rw,vers=4,addr=12.34.56.78,clientaddr=192.168.1.xxx)








  Testing the NFS Mount
Once you have successfully mounted your NFS
directories, you can test that they work by creating files on the Client
and checking their availability on the Server.



Create a file in each directory to try it out:

touch /mnt/nfs/fs-01.sda1/test.txt



touch /mnt/nfs/fs-01.sdb1/test.txt






You should then be able to find the files on the Server in the /home and /var/nfs directories.



ls /home






ls /mnt/nfs/






You can ensure that the mount is always active by adding the directories
to the fstab file on the client. This will ensure that the mounts start
up after the server reboots.

vi /etc/fstab



fileshare-01:/mnt/local/sda1/ /mnt/nfs/fs-01.sda1/ nfs4 _netdev,auto,retry=1,nolock,bg,intr 0 0

fileshare-01:/mnt/local/sdb1/ /mnt/nfs/fs-01.sdb1/ nfs4 _netdev,auto,retry=1,nolock,bg,intr 0 0



You can learn more about the fstab options by typing in:



man nfs




Any subsequent restarts will include the NFS mount—although the mount
may take a minute to load after the reboot You can check the mounted
directories with the two earlier commands:

df -h






mount






 Removing the NFS Mount
Should you decide to remove a directory, you can unmount it using the umount command:



sudo umount /directory name





You can see that the mounts were removed by then looking at the filesystem again.

df -h





You should find your selected mounted directory gone.
