How to Mount the Amazon EFS File System on the EC2?

- 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
