Installing NFS (Network File System) on Ubuntu 18.04

NFS (Network File System) is a distributed file system protocol that allows you to share files and directories with other Linux/Unix clients over a network. It allows you to mount remote directories on your local machine and access them as if they were on your local filesystem.

Here are the steps to install and configure NFS on Ubuntu 18.04:

sudo apt update

sudo apt install nfs-kernel-server

sudo mkdir /shared-directory

sudo chown nobody:nogroup /shared-directory
sudo chmod 777 /shared-directory

sudo nano /etc/exports

/shared-directory client_ip_address(rw,sync,no_subtree_check)

sudo exportfs -a

sudo systemctl restart nfs-kernel-server

sudo ufw allow from client_ip_address to any port nfs

sudo mount server_ip_address:/shared-directory /mount-directory

1. Update your system's package repository:
2. Install the NFS server package:
3. Create a directory to be shared:
4. Set appropriate permissions for the shared directory:
5. Edit the NFS server configuration file:
6. Add the following line to the end of the file to define the shared directory and the clients that can access it:
7. Note: Replace "client_ip_address" with the actual IP address of the client machine that you want to grant access to.
8. Save and close the file.
9. Export the shared directory:
10. Restart the NFS server:
11. Allow NFS through the firewall:
12. Note: Replace "client_ip_address" with the actual IP address of the client machine.
13. Finally, mount the shared directory on the client machine:
14. Note: Replace "server_ip_address" with the IP address of the NFS server, and "/mount-directory" with the local directory where you want to mount the shared directory.

You have successfully installed and configured NFS on Ubuntu 18.04. You can now share files and directories between your server and client machines over the network.

Remember to replace "client_ip_address" and "server_ip_address" with the actual IP addresses of your client and server machines respectively.
