The Simple Setup of NFS On Single Device.

About NFS:

Network File System is a distributed file system.

developed by :  SUN Microsystems in 1984.

- User can access files over network much like local storage.

  

Set up NFS on Single Device:

OS: Ubuntu 14.04

1:  Install packages :

       sudo apt-get install nfs-kernel-server portmap

2:  Choose which Directory to be shared.

     suppose, we want to share  /home/youandme

     if there is no directory of youandme...

     you can create it:
                 sudo -s

                mkdir /home/youandme
 
        check by :  ls /home

3:  Permissions:

        give permissons

            chown  nobody:nogroup  /home/youandme

 4: Registor the directory to exports:

                  

        nano /etc/exports

       

      

       -file is opened.. add below line at end of file.

      

         /home/youandme  127.0.0.1(rw,sync,no_root_squash,no_subtree_check)

       - press ctrl+O to save
       -  Enter
       - press ctrl+X to exit. 

  5:    In above line.

       -    /home/youandme is directory to be shared.

       -   127.0.0.1 is ip of ur laptop/pc 

              -  u can get it by:

                       

                           ifconfig

               -  find inet addr: 127.0.0.1    (something like this..)

         -  U can also give only ur Username instead of 127.0.0.1 

                         like..  my username is matrix.
                      /home/youandme  matrix(rw,sync,no_root_squash,no_subtree_check)

         - (rw,sync,no_root_squash,no_subtree_check) are the serveral tasks:

                  rw  - read and write in shared directory.

                  sync - confirms request to shared directory only the changes have been committed.

                  no_subtree_check  -  this option prevents the subtree checking.

                  no_root_squash  - this allow root to connect to designated directory.

 6:  Run the following command to export the file:

         

             exportfs -a

///@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

                         

                                            ......INTERVAL....

//############################################################

 below commands can be done on different Computer or Same.

7:  apt-get install nfs-common portmap    //client setting..

8:   create the directory or choose the directory, where u would want to see the shared file.

         suppose i want to see all /home/youandme file  in  /home/friends

           create /home/friends :      

                                  mkdir -p  /home/friends

 9:   finally mount..

            mount 127.0.0.1:/home/youandme   /home/friends

//@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

   

you can check it by 

           df    -h

10:     TEST: 

                 create one file in /home/youandme

   

                 check in /home/youandme   AND ... it will be in /home/friends also..!!

           

      

//##############################################################

11:   u can keep this mount active by adding the directory to fstab.

            

                   nano /etc/fstab

          - file opened... add below line.

           

     127.0.0.1:/home/youandme   /home/friends  nfs  auto,noatime,nolock,bg,nfsvers=3,intr,tcp,actimeo = 1800 0 0

                  

                                             

//@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

12: To  Remove the mount do as follow:

              cd

              sudo umount /home/friends

         - check by 

            

               df -h

//@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
