CONFIGURE NFS (Network File System) SERVER AND CLIENT

*NFS (Network File System)

NFS used for sharing files over network between

☼  Linux → Linux

☼  Linux ↔ Unix

☼   Unix → Unix

1-      Installing Packages: (nfs4, nfs-utils, rpcbind (On Server Machine)

•  [root@server2 ~]# yum install nfs* -y  (install nfs4 + utilities + rpcbind. “-y= yes”)
• [root@server2 ~]# rpm -qa |grep nfs (check nfs if installed successfully)
• [root@server2 ~]# rpm -qa |grep rpcbind (check rpcbind if installed successfully)

2-      Restarting the services

1.  [root@server2 ~]# service rpcbind restart
2. [root@server2 ~]# service nfs restart
3. [root@server2 ~]# service nfslock restart

3-      Turn on these Services permanently

• [root@server2 ~]# chkconfig nfs on
• [root@server2 ~]# chkconfig nfslock on
•  [root@server2 ~]# chkconfig rpcbind on

 

4-      Create some folder to be shared or Share existing folder

♫ [root@server2 ~]# mkdir /nfs/resource -p

♪  [root@server2 ~]# mkdir /nfs/projects -p

[root@server2 ~]# mkdir /nfs/software –p

ü  [root@server2 ~]# mkdir /nfs/media –p

 

5-      Edit Export file “located at” /etc/exports

ý  vi /etc/exports (Don’t worry this is an Empty file, add folder name and folder path that you want to share with permission type) Example:

»        /nfs/software   *(rw,sync)

»        /nfs/resource   192.168.78.0/24(ro,sync)

»        /nfs/projects   *.server1.com, *.sever2.com(rw,sync)

»        /nfs/media      192.168.78.130/32(rw,sync)                (press “ESC” →:wq← =save and Exit

Note: *=Any user / rw=Read Write permission / ro=Read Only permission / sync=Synchronize / 192.168.78.0/24=Permission for all 254 node on this network /*.server1.com, *.sever2.com= Permission for all Member of server1.com and server2.com/ 192.168.78.130/32= Permission for only this IP

6-      Restarting nfs service,→ check shared resources → re Export Shared resources _(optional)

_v   [root@server2 nfs]# service nfs restart

_v   [root@server2 nfs]# showmount -e localhost            _OR

_v    [root@server2 nfs]# showmount -e 192.168.78.101    _{(*change to your own IP  “View All shared Resources)}

_v    [root@server2 nfs]# exportfs -ra       _{(Optional only for double Ensure “-ra”= Re Export All Shared directories)}

 

7-      Configure Clint Machine

©    [root@clint ~]# yum install nfs* -y

©    [root@clint ~]#showmount -e server2.com    _{(Use Server Name or Server IP “View All shared Resources Server)}

©     [root@clint ~]# mkdir /mnt/nfs -p     _{(optional create new folder )}

©     [root@clint ~]# mount -t nfs server2.com:/nfs/software /mnt/nfs       _{(Mount software folder “Server IP can be used instead of Sever name )}

©     [root@clint ~]# echo $?          _{(if output “0” = mounted successfully, if output not “0”= there is a problem)}

©     [root@clint ~]# cd /mnt/nfs

©     [root@clint nfs]# ls

©     [root@clint nfs]# vi /etc/fstab                        _{(permanent mount for shared folder’ “just add 1 line at the bottom of the fstab file)}

_»                   server2.com:/nfs/software     /mnt/nfs         nfs       default             0          0
