How to Configure CentOS 6 NFS Service

Thu, Jun 5, 2014

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
