Launching Riak VMs via the AWS Marketplace
In order to launch a Riak virtual machine via the AWS Marketplace, you will first need to sign up for an Amazon Web Services account.
Navigate to https://aws.amazon.com/marketplace/ and sign in with your Amazon Web Services account.
Locate Riak in the Databases & Caching category or search for Riak from any page.
Set your desired AWS region, EC2 instance type, firewall settings, and key pair
Click the Accept Terms and Launch with 1-Click button.
Security Group Settings
Once the virtual machine is created, you should verify that your selected EC2 security group is properly configured for Riak.
In the AWS EC2 Management Console, click Security Groups, then click the name of the security group for your Riak VM.
Click on the Inbound tab in the lower pane. Your security group should include the following open ports:
- 22 (SSH)
- 8087 (Riak Protocol Buffers Interface)
- 8098 (Riak HTTP Interface)
You will need to add additional rules within this security group to allow your Riak instances to communicate. For each port range below, create a new Custom TCP rule with the source set to the current security group ID (found on the Details tab).
- Port range: 4369
- Port range: 6000-7999
- Port range: 8099
When complete, your security group should contain all of the rules listed below. If you are missing any rules, add them in the lower panel and then click the Apply Rule Changes button.
We also recommend that you read more about Riak’s Security and Firewalls.
Clustering Riak on AWS
You will need need to launch at least 3 instances to form a Riak cluster. When the instances have been provisioned and the security group is configured, you can connect to them using SSH or PuTTY as the ec2-user.
You can find more information on connecting to an instance on the official Amazon EC2 instance guide.
On the first node, obtain the internal IP address:
For all other nodes, use the internal IP address of the first node:
sudo riak-admin cluster join riak@<ip.of.first.node>
After all of the nodes are joined, execute the following:
sudo riak-admin cluster plan
If this looks good:
sudo riak-admin cluster commit
To check the status of clustering use:
sudo riak-admin member_status
You now have a Riak cluster running on AWS.
