NFS quick howto for centos 5

To use nfs successfully, you have to configure the server and the client. In this example, the client is 192.168.0.3 and the server is 192.168.0.1. 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
• # vi /etc/exports
• Add this line:
• /home/sharing 192.168.0.3/255.255.255.255(rw,sync)
3. Save
4. Edit /etc/hosts.allow
• # vi /etc/hosts.allow
• Add this line:
• portmap: 192.168.0.0/255.255.255.0
5. Save
6. 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 192.168.0.1:/home/sharing /mnt
3. Check /var/log/messages for any error that might occur
• # tailf /var/log/messages
4. Use mount to check if the folder is mounted properly
• # mount 
• This should be the output:
• 192.168.0.1:/home/sharing on /mnt type nfs (rw,addr=192.168.0.1)
5. Edit /etc/fstab to mount the shared folder on boot
• # vi /etc/fstab
• Add this line
• 192.168.0.1:/mnt/sdb1/backup /mnt nfs rw,hard,intr 0 0
6. Save

You can use 'man exports' to see the options available for /etc/exports
