Installing NFS (Network File System) on CentOS 8

NFS (Network File System) is a distributed file system protocol that allows you to share files and directories between multiple Linux or Unix-like systems over a network. It enables you to access remote files as if they were on your local system.

To install NFS on CentOS 8, follow these steps:

sudo dnf update

sudo dnf install nfs-utils

sudo systemctl start nfs-server
sudo systemctl enable nfs-server

The NFS server is now running on your system.

sudo mkdir /mnt/nfs_share

sudo chown nobody:nobody /mnt/nfs_share
sudo chmod 777 /mnt/nfs_share

sudo nano /etc/exports

Add the following line to the file:

/mnt/nfs_share *(rw,sync,no_subtree_check)

Save and close the file.

sudo exportfs -a

sudo firewall-cmd --add-service=nfs --permanent
sudo firewall-cmd --reload

If you want to allow specific client systems to access the NFS server, you can specify their IP addresses or hostnames in the /etc/exports file. For example:

/mnt/nfs_share client1.example.com(rw,sync,no_subtree_check)
/mnt/nfs_share 192.168.0.100(rw,sync,no_subtree_check)

Save the file and export the changes by running sudo exportfs -a.

sudo mkdir /mnt/nfs_client
sudo mount nfs_server_ip:/mnt/nfs_share /mnt/nfs_client

Replace nfs_server_ip with the IP address of the NFS server.

1. Update the system packages:
2. Install the NFS package:
3. Start and enable the NFS server:
4. Create a directory to be shared:
5. Set the appropriate permissions for the shared directory:
6. Edit the exports file to configure the shared directory:
7. Export the shared directory:
8. Allow NFS traffic in the firewall:
9. Configure client access (optional):
10. Mount the NFS share on the client system:

You have successfully installed and configured NFS on CentOS 8. Now you can access the shared directory on the client system.
