Mounting EFS file system to AWS EC2 ubuntu 18, 20 and 22

Step 1:

create security group for nfs access points

The source needs to be the target servers

Step 2:

create file system

while creating file system make sure to select the proper security group

Step 3:

login to ubuntu and create folder /mnt/efs/

mkdir /mnt/efs/

Step 4:

install amazon-efs-utils package

For information you can visit to [Manually installing the Amazon EFS client – Amazon Elastic File System]

Follow following commands to install on Ubuntu

sudo apt update
sudo apt -y install git binutils
git clone https://github.com/aws/efs-utils
cd efs-utils
./build-deb.sh
sudo apt -y install ./build/amazon-efs-utils*deb

Step 5:

visit efs section click on file system id

from the details page find out the attach button and click on to get the command

in my case i got following using EFS Mount:

sudo mount -t efs -o tls fs-radond-number-of-efs-id:/ /mnt/efs/app.example.com

mount file system automatically on reboot

This is must follow step without this your efs file system will not be useful

Step 1:

Make sure to replace the id of your file system id
add following line to fstab – so that it will automatically mount to your server when system get rebooted

nano /etc/fstab

fs-eft-id.efs.us-east-1.amazonaws.com:/	/mnt/efs	nfs4	_netdev,nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport,nofail 0 0

Step 2:

Ensure that on the fstab file you use the exact path

sudo mount -fav

unmount

sudo umount /mnt/efs

or 

sudo umount -f /mnt/efs

assign write access to the web user

Assign the proper access so that web server(s) should be able to write/store whatever want store

cd /mnt/efs
sudo chgrp -R www-data app.example.com
sudo chmod -R ug+rwx app.example.com

Mounting via IP

Install the botocore lib

apt install python3-pip
 sudo pip3 install botocore

sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport <REPACE_IP_ADDRESS_HERE>:/ efs
