Step1: Installing the packages
# yum install nfs-utils nfs4-acl-tools portmapSome facts about the tools above as given from yum info.
nfs-utils - The nfs-utils package provides a daemon for the kernel NFS server and related tools, which provides a much higher level of performance than the traditional Linux NFS server used by most users.
This package also contains the showmount program. Showmount queries the mount daemon on a remote host for information about the NFS (Network File System) server on the remote host. For example, showmount can display the clients which are mounted on that host. This package also contains the mount.nfs and umount.nfs program.
nfs4-acl-tools – This package contains commandline and GUI ACL utilities for the Linux NFSv4 client.
portmap - The portmapper program is a security tool which prevents theft of NIS (YP), NFS and other sensitive information via the portmapper. A portmapper manages RPC connections, which are used by protocols like NFS and NIS.
The portmap package should be installed on any machine which acts as a server for protocols using RPC.
Step 2: Exports the File System from the NFS Server (Similar to NFSv3 except with the inclusion of fsid=0)
/home 192.168.1.0/24(rw,no_root_squash,sync,no_subtree_check,fsid=0) /install 192.168.1.0/24(rw,no_root_squash,sync,no_subtree_check,fsid=1)The fsid=0 and fsid=1 option provides a number to use in identifying the filesystem. This number must be different for all the filesystems in /etc/exports that use the fsid option. This option is only necessary for exporting filesystems that reside on a block device with a minor number above 255.one directory can be exported with each fsid option.
Exports the file system
# exportfs -av
Restart the NFS service
# service nfs startIf you are supporting NFSv3, you have to start portmap as NFSv3 requires them. As such, NFSv4 does not need to interact with rpcbind, rpc.lockd, and rpc.statd daemons. For more information see Fedora Chapter 9. Network File System (NFS) – How it works for a more in-depth understanding.
# service portmap restart
Step 2: Client Mapping
# mount -t nfs4 192.168.1.1:/ /home
