Step 3: Connect to Your Amazon EC2 Instance and Mount the Amazon EFS File System

You can connect to your Amazon EC2 instance from a computer running Windows or Linux. To connect to your Amazon EC2 instance and mount the Amazon EFS file system, you need the File system ID value for the mount target for your Amazon EFS file system. You made a note of this value at the end of Step 2: Create Your Amazon EFS File System.

To connect to your Amazon EC2 instance and mount the Amazon EFS file system

  1. Connect to your Amazon EC2 instance. For more information, see Connecting to Your Linux Instance from Windows Using PuTTY or Connecting to Your Linux Instance Using SSH in the Amazon EC2 User Guide for Linux Instances.

  2. After you've connected, install the amazon-efs-utils package, which has the Amazon EFS mount helper.

    Run the following command to install amazon-efs-utils.

    sudo yum install -y amazon-efs-utils


    For more information on the amazon-efs-utils package, including installation instructions for other Linux distributions, see Using the amazon-efs-utils Tools.

  3. Make a directory for the mount point with the following command.

    $ sudo mkdir efs
  4. Mount the Amazon EFS file system to the directory that you created. Use the following command and replace file-system-id with your File System ID value.

    sudo mount -t efs fs-12345678:/ /mnt/efs


    We recommend that you wait 90 seconds after creating a mount target before you mount your file system.

  5. Change directories to the new directory that you created with the following command.

    $ cd efs
  6. Make a subdirectory and change the ownership of that subdirectory to your EC2 instance user. Then navigate to that new directory with the following commands.

    $ sudo mkdir getting-started $ sudo chown ec2-user getting-started $ cd getting-started
  7. Create a text file with the following command.

    $ touch test-file.txt
  8. List the directory contents with the following command.

    $ ls -al

As a result, the following file is created.

-rw-rw-r-- 1 ec2-user ec2-user 0 Aug 15 15:32 test-file.txt
