NFS: Provide network shares to specific clients

Install the NFS packages:

# yum groupinstall -y "NFS file server"

Add new rules to the firewall:

# iptables -I INPUT -m state --state NEW -m udp -p udp --dport 111 -j ACCEPT
# iptables -I INPUT -m state --state NEW -m tcp -p tcp --dport 111 -j ACCEPT
# iptables -I INPUT -m state --state NEW -m tcp -p tcp --dport 2049 -j ACCEPT

Save the firewall configuration:

# service iptables save

Activate the NFS services at boot:

# chkconfig rpcbind on
# chkconfig nfs on
# chkconfig nfslock on

Start the NFS services:

# service rpcbind start
# service nfs start
# service nfslock start

Create directories to export and assign access rights:

# mkdir -p /home/tools
# chmod 777 /home/tools
# mkdir -p /home/guests
# chmod 777 /home/guests

Edit the /etc/exports file and add the following lines with the name (or IP address) of the client(s):

/home/tools client1(rw,no_root_squash)
/home/guests client2(rw,no_root_squash)

Note: Please, don’t put any space before the open parenthesis, this would completely change the meaning of the line!

Export the directories:

# exportfs -avr

Note: On the client side, the commands are:

# yum install -y nfs-utils
# mount -t nfs server:/home/tools /mnt
