Login as a root user, Open the NFS configuration file
# vi /etc/exports
In the above example, there is a directory in / partition named “nfs” is being shared with client IP “0.0.0.0/0” i.e., any address with read and write (rw) privilege, you can also use specific network or hostname of the client in the place of IP in above example.
rw: This option allows the client server to both read and write access within the shared directory.
no_root_squash -- This phrase allows root to connect to the designated directory.
Root squashing is enabled by default and you need to disable it explicitly.
