How to install MYSQL NDB cluster

In the tutorial we will install MYSQL Network Database cluster (NDB) using 4 nodes.

Prerequisites

To complete this tutorial, you'll need the following:

• 1 management node
• 2 data nodes
• 1 SQL node

Naming db2004.dfw.ppnet = SQL node db2005.dfw.ppnet = 1st data node db2006.dfw.ppnet= 2nd data node db2008.dfw.ppnet= management node

Hardware/software requirements

I am running this in a VM environment. All nodes have 1Gb of RAM and 20GB of disk. To run this in a productions environment please refer to the MSQL NDB cluster documentation.

All 4 nodes are running Debian stretch
