Create m3 large instance for SOA installation on AWS -EC2.

 1. Choose Static Elastic IP. So that you do not loose IP when server is restarted.

  

 2.  Save the KeyPair on local Machine.  Use PuttyGen to create the PPK file.

 3. Use Putty to login to the terminal using the PPK.  

      a. Hostname:  Public DNS name from AWS console.

      b. Port : 22  for ssh.  

      c.  Putty-> connection -> ssh -> Auth -> Browse for PPK file.

Change Hostname to Fully Qualified name.

HOSTNAME=obprodb.objectprosolutions.com

Direct your custom hostname to AWS Public IP:

Create the A Record in your DNS control pointing to AWS PUBLIC IP.

Create User:

From Root user:


ec2-user> sudo useradd oracle

ec2-user> sudo su - oracle

oracle> mkdir .ssh

oracle> chmod 700 .ssh

oracle> touch .ssh/authorized_keys

oracle> chmod 600 .ssh/authorized_keys

oracle> vi .ssh/authrized_keys

Paste the public key here.  

P.S:  PuttyGEN is used to dispaly the public key 

Now login to terminal using the new user 'oracle'.

su - oracle

mkdir .ssh

chmod 700 .ssh

touch .ssh/authorized_keys
