Introduction

In addition to the Instance-backed EC2 AMI that has been in existence since 2008, Virtuoso is now also available as an EBS-backed EC2 AMI based on your choice of License Model --

Bring You Own License, or BYOL (documented here)
Pay As You Go, or PAGO

With either License Model, you will be starting with a preconfigured Virtuoso instance. The fundamental benefits provided by this type of AMI include:

Virtuoso is preinstalled and tuned for the host operating system
You can start and stop this Virtuoso instance without having to terminate its host AMI

BYOL simply requires that you acquire a Virtuoso License, as you would for any other deployment, and then apply that license to the preconfigured Virtuoso instance that awaits you in the Amazon EC2 Cloud.

Prerequisites

An Amazon Web Services (AWS) account.
Recently created AWS accounts will have been automatically signed up for the Amazon S3 and EC2 Web Service. If you created your AWS account a long time ago, you may now need to manually sign up for these services.
A Virtuoso commercial license for Linux, purchased from the Virtuoso Web Site.

Setup & Instantiation of the EBS-backed BYOL Virtuoso AMI

From the AWS Management Console, select Launch Instances.

You will need to choose an AMI. In the Community AMIs tab, type Virtuoso 7.1 in the search box to find the relevant images published by OpenLink —

Edition	ID	Description
64-bit	`ami-c04220a8`	`Virtuoso 7.1 (for Red Hat Enterprise Linux)`

Choose the Instance Type the AMI is to be instantiated with.
Configure your Instance Details.
Add Storage, selecting a suitably sized storage device.
Tag the Instance(s) with a suitable name for your own purposes.
Configure network access security. Note that port 22 is always required for ssh access to the AMI, and port 80 is needed for HTTP access to the Virtuoso server instance. Access to port 1111 may also be needed, if access to the Virtuoso SQL port is required, and/or port 443, if HTTP+TLS will be needed.
Review the Instance settings before clicking Launch to instantiate the AMI.
Select a suitable pre-existing security key pair, or choose to create a new pair, for instance instantiation and access, and Launch the instance.
The Launch Status page will be displayed for tracking progress.
Once complete, view the Launched Instance page in AWS console to see the instantiated AMI.

After AMI Instantiation

Locate the security key selected or created above, and run the command —
```
chmod 600 MyKeyPair.pem
```
Copy your Virtuoso license file (virtuoso.lic) to the AMI instance, using the default "ec2-user" that has "sudo" rights, with the command —
```
scp -i MyKeyPair.pem virtuoso.lic ec2-user@your-ec2-instance-cname:~/
```
Connect to the EC2 AMI Server using the default "ec2-user" that has "sudo" rights, with the command —
```
ssh -i MyKeyPair.pem ec2-user@your-ec2-instance-cname
```
The Virtuoso EC2 AMI installation is located in /opt/virtuoso. Run the following commands to navigate to this location, and set the Virtuoso server environment variables —
```
cd /opt/virtuoso
. ./virtuoso-environment.sh
```
Run the following command to copy the Virtuoso license to the bin directory of your Virtuoso installation
```
sudo cp ~/virtuoso.lic bin/virtuoso.lic
```
Run the following command to start the default Virtuoso database located in the database directory.
```
sudo bin/virtuoso-start.sh database
```

The Virtuoso instance should now be running. This can be verified by checking the virtuoso.log file in the database directory, with a command like this:


tail -n 100 database/virtuoso.log

Output will look something like this:
