Tài liệu High Availability MySQL Cookbook phần 2

In this recipe, we will discuss the initial configuration required to start a MySQL Cluster.
A MySQL Cluster has a global configuration file—config.ini, which resides on all
management nodes. This file defines the nodes (processes) that make up the cluster
and the parameters that the nodes will use.
Each management node, when it starts, reads the config.ini file to get information on the
structure of the cluster and when other nodes (storage and SQL / API) start, they contact the
already-running management node to obtain the details of the cluster architecture.
The creation of this global configuration file—config.ini, is the first step in building the
cluster and this recipe looks at the initial configuration for this file. Later recipes will cover
more advanced parameters which you can define (typically to tune a cluster for specific
goals, such as performance).
