“So then what is the purpose of this article? To let you setup a
MySQL Cluster for fun, on a single box, so you can test out its
features1. The main things I wanted to test out are:“Setting up a cluster on one or two boxes. People tell me this
is impossible. For personal and business reasons, this article
attempts to squash those rumors so I can just point people to this
article instead of explaining the details to them. There are
advantages to setting up a cluster on 3 boxes as compared to 2
boxes, however. There is a difference between a network outage and
a single server becoming unavailable and 3 servers help with
this.“Using other storage engines and setup dangerous replication
between the frontend MySQL servers. Replicating data to a cluster
slave as well as a normal slave.“There is also one important item to keep in mind about MySQL
Cluster. I have no idea why they make “MySQL Cluster” as a separate
product from the main MySQL server. In the past, the “MySQL
Cluster” was just the NDB engine running in MySQL. It seems to be
the same way even now and I suspect that it might just be due to
politics and marketing that they have something called a “MySQL
Cluster” when it is really just MySQL with the NDB engine. The
mysqld server running in “MySQL Cluster” can still store data in
InnoDB and MyISAM formats.”
