• Set the username and password for the master user.

• Once the role is created, you will see a confirmation page with the role details.

  

Assign the role to EC2 so that your EC2 Instance can connect with RDS

• Select the IAM role that you want to assign to the EC2 instance and Click on the "Update IAM role" button to attach the IAM role to the instance.

  

Once the RDS instance is up and running, get the credentials and connect your EC2 instance using a MySQL client.

• Go to the RDS console and see database is created.

  

• Click on the database name and copy the endpoint from the connectivity & security section.

  

• Connect the instance using ssh.

  

• Install mysql and check the version to verify the installation.

  

  

• Use the mysql -h <Endpoint> -P <portno.> -u <Username> -p command to connect to the RDS. You can see SQL is connected.
