MySQL Cluster Multi Computer How To


This section is a “How-To
” that describes the basics
for how to plan, install, configure, and run a MySQL Cluster.
Whereas the examples in
Chapter 3, MySQL Cluster Configuration
provide more in-depth
information on a variety of clustering options and configuration,
the result of following the guidelines and procedures outlined here
should be a usable MySQL Cluster which meets the
minimum
requirements for availability and
safeguarding of data.

This section covers hardware and software requirements; networking
issues; installation of MySQL Cluster; configuration issues;
starting, stopping, and restarting the cluster; loading of a sample
database; and performing queries.

Basic assumptions. 
This How-To
makes the following
assumptions:
