• Mount the Amazon EFS File System on the EC2
• Public DNS name of your EC2 instance in the following format:
  • Ec2-xx-xxx-xxx-xx.aws-region.compute.amazonaws.com
• DNS name of your file system. You can construct this DNS name using the following generic form:
  • File-system-id.efs.aws-region.amazonaws.com

• Install the NFS Client on Your EC2 Instance
• Execute the following commands on the EC2 instance by using the SSH session:

$ sudo yum -y update

$ sudo reboot 

• Install the NFS client.

sudo yum -y install nfs-utils

• Install the NFS Client on Your EC2 Instance
• Execute the following commands on the EC2 instance by using the SSH session:

$ sudo yum -y update

$ sudo reboot 

• Install the NFS client.

sudo yum -y install nfs-utils

• Mount File System on Your EC2 Instance
• Make a directory (“efs-mount-point”).

mkdir ~/efs-mount-point

• Mount the Amazon EFS file system.

sudo mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport mount-target-DNS:/   ~/efs-mount-point

• The EC2 instance can resolve the mount target DNS name to the IP address. You can optionally specify the IP address of the mount target directly.

sudo mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport mount-target-ip:/  ~/efs-mount-point

• To check that the mount is done or not

cd /efs-mount-point

• Create a new file

sudo mkdir new-file-name

• How to create a bootstrap script to attach the EFS on launch to an EC2 instance?
• When we want to implement something without even logging in into an EC2 Instance, then bootstrap scripts can be used in order to achieve that
• In our case we want to make sure that when we logging to our server our EFS is already connected to the server
• Also we can attach this bootstrap to launch configuration in an autoscaling which will to maintain the latest updated files in the server
• Bootstrap Script

#/bin/bash

sudo yum -y update

sudo yum -y install nfs-utils

sudo mkdir ~/efs-mount-point

sudo mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport mount-target-DNS:/   ~/efs-mount-point

• Explanation Bootstrap Script

#/bin/bash

• This will make sure that commands are running to the write path

sudo yum -y update 

• This will update the server and will have latest dependencies

sudo yum -y install nfs-utils

• This will install the NFS client inside the server which will help to connect the EFS file

sudo mkdir ~/efs-mount-point

• This will make a directory inside the server to which the EFS will be mounted

sudo mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport mount-target-DNS:/   ~/efs-mount-point

• This is the detail information of the EFS file and path to connect
