sudo mkdir /mnt/my_data
- Next, assign ownership and permissions.
sudo chown nobody:nogroup /mnt/my_data
sudo chmod -R 777 /mnt/my_data
Configure Exports for client
- Allow client access by editing the exports configuration file. Use the following command to open the exports file.
sudo nano /etc/exports
- Add client that can access the NFS server using the following line in the config file. Note, you can add several lines with different clients IP to add more clients.
Above command meaning;
- rw-Read and Write )
- sync-Write changes to disk before applying them)
- no_subtree_check-Avoid subtree checking )
Then, using the following command, export the shared directory.
sudo exportfs -a
Allow NFS Share Access on Firewall

sudo mkdir -p /mnt/client_directory
- Mount the remote NFS share directory with the command below after you’ve created the mount directory.
sudo mount SERVER-IP:/mnt/my_data /mnt/client_directory
Test NFS Share
- Navigate to your directory share on the NFS server and create a test file.
- List the content of the mounted share directory on your client system.
In the client directory, you should be able to see the contents of the server.
- It’s a warp, you have reached the end of the article. You now know how to Install NFS Server on Debian 11.
