Mount Up! A Step-by-Step Guide to Creating and Using Amazon EFS on Ubuntu

#aws #efs #storage #cloudcomputing

Amazon Elastic File System (EFS) provides a simple, scalable, and fully managed Network File System for use with AWS Cloud services and on-premises resources. This guide will walk you through the process of creating an EFS, mounting it on an Ubuntu instance, and adding files to it.

Prerequisites

An AWS account
An EC2 instance running Ubuntu in the same VPC as your EFS file system
Proper security group settings to allow NFS traffic

Step 1: Create an EFS File System

1.. Navigate to the EFS Dashboard

Open the AWS Management Console.
Go to the EFS dashboard.
Create a File System

2.. Click on "Create file system".

Follow the prompts to set up your EFS file system. You can choose the VPC, security group, and performance mode as per your requirements.

Step 2: Configure Security Groups

1.. EFS Security Group

Ensure the security group associated with your EFS allows inbound traffic on port 2049 (NFS).

2.. EC2 Security Group

Modify the security group associated with your EC2 instance to allow NFS traffic from the security group used by the EFS.

Step 3: Install NFS Client on Ubuntu

1.. Connect to Your EC2 Instance

Use SSH to connect to your EC2 instance.

2.. Install NFS Client using the following script:

- sudo apt-get update sudo apt-get install -y nfs-common

Step 4: Create a Mount Point

1.. Create a Directory to Mount EFS using the following script:

- sudo mkdir /mnt/efs

Step 5: Mount the EFS File System

1.. Mount the EFS File System using the following script:

- sudo mount -t nfs4 -o nfsvers=4.1 < file-system-id >.efs. < region >.amazonaws.com:/ /mnt/efs

Note: Be sure to replace file-system-id with your EFS file system ID and region with the appropriate AWS region (e.g., us-west-2).

Step 6: Verify the Mount

1.. Check the Mount Point using the following script:

- ls /mnt/efs

Step 7: Add Files to EFS

1.. Copy Files to the EFS using the following script:

- sudo cp /path/to/local/file /mnt/efs/

and / or

2.. Create Files Directly in EFS using the following script:

- echo "Hello, EFS!" | sudo tee /mnt/efs/hello.txt

Summary

There you have it! By following these steps, you can easily create an Amazon EFS, mount it on your Ubuntu instance, and add files to it. EFS provides a solution for storing files in the cloud, accessible from multiple instances as well as on-premises environments.
