Server Side

  1. Disable SeLinux
    Edit the configuration file:

    vi /etc/selinux/config

    Modify as follows:

    #SELINUX=enforcing    # Comment out
#SELINUXTYPE=targeted # Comment out
SELINUX=disabled      # Add this line

    Then reboot the system:

    reboot  # Restart the system

  2. Create a Directory
    Using the root user, create a directory named /nfs. Note: It’s best to check which partition has the most space by running df, as the root (/) partition may not have the most space. In some automatic partitioning setups, the /home partition may have the most space.

  3. Install NFS Utilities and RPC Bind

    yum -y install nfs-utils rpcbind

  4. Enable Services at Boot

    chkconfig nfs on
chkconfig rpcbind on
chkconfig nfslock on

  5. Configure Exports
    Edit the NFS exports file:

    vi /etc/exports

    Add the following line:

    /home/nfs 192.168.1.0/24(rw,sync,no_all_squash)

  6. Start NFS Services

    service rpcbind start
service nfs start
service nfslock start
exportfs -a

  7. Configure NFS Ports
    Edit the NFS configuration file:

    vi /etc/sysconfig/nfs

    Uncomment the following lines:

    LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
MOUNTD_PORT=892

  8. Restart NFS Services

    service rpcbind restart
service nfs restart
service nfslock restart

  9. Verify RPC Services

    rpcinfo -p localhost

    Note down the ports and their types.

  10. Configure Firewall Rules
    Adjust the IP range according to your network:

    iptables -I INPUT -m state --state NEW -p tcp -m multiport --dport 111,892,2049,32803 -s 192.168.0.0/24 -j ACCEPT
iptables -I INPUT -m state --state NEW -p udp -m multiport --dport 111,892,2049,32769 -s 192.168.0.0/24 -j ACCEPT

  11. Save Firewall Rules
    Test from the client side. If successful, save the iptables configuration:

    service iptables save

Client Side

  1. Create Mount Point

    mkdir /nfs

  2. Check RPC Services on Server

    rpcinfo -p [server_ip]

  3. Show NFS Exports

    showmount -e [server_ip]

  4. Mount NFS Share

    mount -t nfs -o soft,intr,bg,rw [server_ip]:/home/nfs /nfs

  5. Unmount NFS Share

    umount /nfs

  6. Configure Automatic Mounting
    Edit the fstab file:

    vi /etc/fstab

    Add the following line:

    [server_ip]:/home/nfs /nfs nfs soft,intr,bg,rw 0 0
