3 Steps to setup SSH remote Access to EC2 from Cloud9

When you need to connect securely to an already running EC2 instance via SSH from a Cloud9, you need to prepare

the instance for Cloud9. AWS Cloud9 generate a SSH public key to connect securely to your EC2 server. To start a secure

connection from Cloud9 via SSH you need to setp the the SSH key, generated by Cloud9, to EC2.

Step 1

Login to the EC2 instance and run the below commands:

sudo yum -y update

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash

export NVM_DIR="/home/ec2-user/.nvm"

[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" 

. ~/.bashrc

nvm install node

sudo chmod u=rwx,g=rx,o=rx ~

sudo yum -y groupinstall "Development Tools"

curl -L https://raw.githubusercontent.com/c9/install/master/install.sh | bash

export NVM_DIR="/root/.nvm"

[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

Step 2

Copy the SSH Key from the Cloud9

Step 3

Paste the SSH key to the ec2-user authorization key.

nano /home/ec2-user/.ssh/authorized_keys
