Installing the NFS client

To connect your EC2 instance and install the NFS client

1. Connect to your EC2 instance. For more information, see Connect to your EC2 instance in the Amazon EC2 User Guide.

   The key file cannot be publicly viewable for SSH. You can use the chmod 400 filename.pem command to set these permissions. For more information, see Create a key pair for your Amazon EC2 instance.

2. (Optional) Get updates and reboot.

   $ sudo yum -y update 
               $  sudo reboot

3. After the reboot, reconnect to your EC2 instance.

4. Install the NFS client.

   If you're using an Amazon Linux AMI or Red Hat Linux AMI, install the NFS client with the following command.

   $ sudo yum -y install nfs-utils

   If you're using an Ubuntu Amazon EC2 AMI, install the NFS client with the following command.

   $ sudo apt-get -y install nfs-common

5. Start the NFS service using the following commands. For RHEL 7:

   $ sudo service nfs start

   For RHEL 8:

   $ sudo service nfs-server start

6. Verify that the NFS service started, as follows.

   $ sudo service nfs status
