NFS Quick howto for CentOS 5


To use NFS successfully, you’ll have to configure the server and the client. In this example, the client is 192.168.10.5 and the server is 192.168.10.1. The folder to be shared is /home/sharing, and to be mounted to /mnt on the client.

On the server:

1. Make directory that you want to use.
# mkdir /home/sharing

2. Edit /etc/exports, insert the client machine’s ip
# nano /etc/exports
Add this line:
/home/sharing 192.168.10.5/255.255.255.0(rw,sync)
Save.

3. Edit /etc/hosts.allow
# nano /etc/hosts.allow
Add this line:
portmap: 192.168.10.0/255.255.255.0
Save.

4. Start NFS and portmap
# /etc/init.d/nfs start
# /etc/init.d/portmap start

 

On the client:

1. Start portmap
# /etc/init.d/portmap start

2. Mount the nfs folder
# mount 192.168.10.1:/home/sharing /mnt

3. chech /var/log/messages for any error that might occur
# colortail -f /var/log/messages

4. Use mount to chech if the folder is mounted properly
# mount
The output should be like this:
192.168.10.1:/home/sharing on /mnt type nfs (rw,addr=192.168.10.1)

5. Edit /etc/fstab to mount the shared folder on boot
# nano /etc/fstab
Add this line:
192.168.10.1:/home/sharing /mnt nfs rw,hard,intr 0 0
Save.
