check if nfs-utils and nfs-utils-lib are installed

[root@apaternina apaternina]# rpm -qa "*nfs*"
nfs4-acl-tools-0.3.3-8.el6.x86_64
nfs-utils-lib-1.1.5-11.el6.x86_64
nfs-utils-1.2.3-70.el6_8.2.x

if not, then install them

[root@apaternina apaternina]# yum install nfs-utils nfs-utils-lib

Nothing to do

configure startup links

[root@apaternina apaternina]# chkconfig --levels 235 nfs on

start service

[root@apaternina apaternina]# service nfs start

edit exports file to declare the directories that will be exported

[root@apaternina apaternina]# vi /etc/exports
/home           192.168.15.6(rw,sync,no_root_squash,no_subtree_check)
/var/nfs        192.168.15.6(rw,sync,no_subtree_check)

export directories

[root@apaternina apaternina]# exportfs -a

make NFS ports fixed

[root@dlp ~]# vi /etc/sysconfig/nfs

# line 20,22: uncomment
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
# line 57: uncomment
MOUNTD_PORT=892
# line 63: uncomment
STATD_PORT=662

allow 111, 2049 and fixed ports above

[root@apaternina apaternina]# for port in 111 662 892 2049 32803; do iptables -I INPUT 5 -p tcp -m state --state NEW -m tcp --dport $port -j ACCEPT; done 
[root@apaternina apaternina]# for port in 111 662 892 2049 32769; do iptables -I INPUT 6 -p udp -m state --state NEW -m udp --dport $port -j ACCEPT; done

make changes to iptables persistent

[root@apaternina apaternina]# service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[  OK  ]

restart rpc and nfs

[root@dlp ~]# /etc/rc.d/init.d/rpcbind restart 
[root@dlp ~]# /etc/rc.d/init.d/nfs restart

client

mount directories in client

mount 192.168.56.100:/home /mnt/nfs/home
mount 192.168.56.100:/var/nfs /mnt/nfs/var/nfs

verify that the directories were mounted successfully

[root@apaternina apaternina]# df -h
