Services Covered

  • EC2 EC2

Lab description

In this lab I will create an Elastic File System that will span across an entire region, mount it to an instance, copy several files, and then mount it to a different instance and retrieve files from it.

Learning Objectives

  • Create file system
  • Install NFS client on the EC2
  • Mount the NFS file system
  • Update the ownership of the efs directory and download a test file to it

Lab date



  • AWS account
  • An EC2 Instance running

Lab steps

  1. In EC2 create a Security Group for the that will allow access to EFS. It should allow inbound access of type NFS from Instances Security group on port 2049.
  2. Create file system in EFS. Keep the default VPC and Regional type, on the Network access tab replace the deafult SG’s with the one created in previous step.

    No need to change anything else. Continue toCreate.
  3. Go back to EC2 and connect to an Instance using EC2 Instance Connect. Leave the window open.
  4. Go back to EFS tab and choose your EFS, then click on Attach. Use the command for Mount via DNS:
    sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport efs

    Save it because for later.

  5. Back in the Instance Connect tab install the NFS Client.
    sudo yum install -y nfs-utils

    Then create a directory to mount the file system:

    mkdir efs 

    Next paste the sudo mount command from previous step and run it. To verify the mount was successful, enter:

    df -h


    Update the ownership of the efs folder to the ec2-user using the following command:

    sudo chown ec2-user efs/
  6. Upload a file to the file system. Navigate to the efs folder:
    cd efs

    Then download for example wordpress distribution

  7. Connect to the second instance. Install NFS Client, create efs directory, run the sudo mount command, change ownership of the efs folder. Navigate to efs folder and run:
    ls -l


    It should display the package downloaded in the first Instance.
