Now we will be creating a directory on host machine which is shared with a client or you can also share already existing directory.
After creating a directory, we need to make or add an entry in “/etc/exports” configuration file and restart the services to make our directory shared on the client system.
In above example, we will be sharing directory /sharenfsdir with client system ip(192.168.3.213) and provided read and write privileges on a shared directory. you can also use HOSTNAME of client machine instead of IP.
To reflect changes from exports config file we need to run below command,
- Restart services on the host machine.
So here we will be completed server or service installation steps.
Configure NFS share directory on Client machine :
Now, we are going to start configuring client machine to access shareable directory.
First we are going to check available shared directory on server for that use below command,
showmount -e 192.168.3.39
Above command shows shared directory /sharenfsdir is available with server ip 192.168.3.39.
To mount that shared directory on client machine we use below mount command,
mount -t nfs 192.168.3.39:/sharenfsdir /mnt/nfsshare [use any path but before mounting on any dir create that directory on system if not available]
with the above help of command we mounted directory on client machine temporarily if you want to make it permanent then add below entry under “/etc/fstab” file.
192.168.3.39:/sharenfsdir /mnt/nfsshare nfs defaults 0 0
Test working of NFS setup :
Create a file under the shared directory on the client machine and checked it on the server it is created or not.
- cd /mnt/nfsshare
- touch nfstestfile.txt
now go on the server and checked under the /sharenfsdir you will found the file under the /sharenfsdir.
To remove NFS mount use below command,
Some important commands for NFS :
- showmount -e : it will shows you available shared directory on server.
- showmount -d : List all the sub directories.
- exportfs -a : it will help to reflect and listed the changes done under the /etc/exports
- exportfs -v : Display’s list of share files and options on server.
- exportfs -r : Reflect the changes after modifying /etc/exports
