Linux Disable / Remove All NFS Services

NFS was not designed with security in mind, and has a number of weaknesses, both in terms of the protocol itself and because any NFS installation must expose several daemons, running on both servers and clients, to network attack. I use my CentOS based server only to server web pages and nothing else. How do I disable NFS services under RHEL / CentOS / Fedora Linux?

You can easily disable NFS, which is a commonly used for sharing data and files between machines. However, its use opens many potential security holes. If NFS is not needed, improve the security by removing and disabling NFS as follows:
# chkconfig nfslock off
# chkconfig rpcgssd off
# chkconfig rpcidmapd off
# chkconfig portmap off
# chkconfig nfs off
Delete nfs-utils and portmap packages:
# yum remove portmap nfs-utils
