This is a quick Howto for setting up MySQL cluster using Amazon EC2 instances. I have used 3 small instances (1 mgmt + 2 data nodes) from RightScale’s CentOS 5 public image to test things. I’ve a working cluster using these steps but there’s no guarantee that these steps works for you as well.

Management server for cluster:
Although we can set up management server for cluster in one of the data node but we should have a third node as if one of the two MySQL cluster nodes fails, and the management server is not running, then the data on the two cluster nodes will become inconsistent and if the same node fails which have management server, then we will not be able to create another node or configure cluster.

For many users, running FTP Sever in Amazon EC2 instance is headache at the first time. You need to experiment before being able to transfer data. The main problems are Ingress firewall in Amazon environment and NAT traversal.

Here I’m using vsftp (vsfptd) Server, which is one of the most popular and easy to configure. The instance is running from base Fedora 4 AMI but the setup should be identical to other Red Hat based distros.

Install vsftpd FTP server, if not installed earlier:

$ yum install vsftpd
