Network File System (NFS) is a distributed file system protocol that allows you to share directories and files between Linux systems over a network. In this guide, we will walk you through how to install and configure both the NFS server and client on Ubuntu 20.04 LTS. Whether you’re using a or another server, NFS provides a simple way to share files between multiple systems.<\/p>\n
Before starting, ensure you have the following:<\/p>\n
On the server machine, install the NFS server package:<\/p>\n
sudo apt update\r\nsudo apt install nfs-kernel-server -y<\/code><\/pre>\nStep 2: Create a Directory to Share<\/h2>\n
Create a directory that will be shared with the NFS client. For example, we will create a directory called \/srv\/nfs_share<\/code>:<\/p>\nsudo mkdir -p \/srv\/nfs_share<\/code><\/pre>\nSet the appropriate permissions for the directory:<\/p>\n
sudo chown nobody:nogroup \/srv\/nfs_share\r\nsudo chmod 755 \/srv\/nfs_share<\/code><\/pre>\nStep 3: Configure NFS Exports<\/h2>\n
Edit the \/etc\/exports<\/code> file to define the shared directory and the client that will be allowed to access it:<\/p>\nsudo nano \/etc\/exports<\/code><\/pre>\nAdd the following line, replacing client_ip<\/code> with the IP address of the client machine:<\/p>\n\/srv\/nfs_share client_ip(rw,sync,no_subtree_check)<\/code><\/pre>\nThis configuration grants read and write access to the client with IP client_ip<\/code> to the \/srv\/nfs_share<\/code> directory. Save and close the file.<\/p>\nStep 4: Export the Shared Directory<\/h2>\n
Export the shared directory to make it available to clients:<\/p>\n
sudo exportfs -a<\/code><\/pre>\nTo apply the changes, restart the NFS server:<\/p>\n
sudo systemctl restart nfs-kernel-server<\/code><\/pre>\nStep 5: Install NFS Client<\/h2>\n
On the client machine, install the NFS client package:<\/p>\n
sudo apt update\r\nsudo apt install nfs-common -y<\/code><\/pre>\nStep 6: Mount the Shared Directory on the Client<\/h2>\n
Create a mount point on the client where the NFS share will be mounted. For example, create a directory called \/mnt\/nfs_share<\/code>:<\/p>\nsudo mkdir -p \/mnt\/nfs_share<\/code><\/pre>\nNext, mount the shared directory from the NFS server:<\/p>\n
sudo mount server_ip:\/srv\/nfs_share \/mnt\/nfs_share<\/code><\/pre>\nReplace server_ip<\/code> with the IP address of the NFS server. The shared directory should now be accessible on the client machine at \/mnt\/nfs_share<\/code>.<\/p>\nStep 7: Verify the NFS Share<\/h2>\n
To verify that the NFS share is mounted, use the df -h<\/code> command to check the mounted file systems:<\/p>\ndf -h<\/code><\/pre>\nYou should see an entry showing that the NFS share from the server is mounted on \/mnt\/nfs_share<\/code>.<\/p>\nStep 8: Make the Mount Permanent (Optional)<\/h2>\n
If you want the NFS share to be automatically mounted at boot, you can add an entry to the \/etc\/fstab<\/code> file on the client machine:<\/p>\nsudo nano \/etc\/fstab<\/code><\/pre>\nAdd the following line at the end of the file:<\/p>\n
server_ip:\/srv\/nfs_share \/mnt\/nfs_share nfs defaults 0 0<\/code><\/pre>\nThis will ensure the NFS share is mounted every time the client reboots.<\/p>\n
Conclusion<\/h2>\n
By following these steps, you have successfully installed and configured NFS server and client on Ubuntu 20.04 LTS. NFS provides a simple way to share files between multiple Linux systems over a network, whether you’re using a , Microsoft SQL VPS Windows<\/a>, or another Windows VPSVirtual Private Server Hosting<\/a> solution.<\/p>\n
