1. 先了解一下你是否应该用MySQL集群。

　　减少数据中心结点压力和大数据量处理，采用把MySQL分布，一个或多个application对应一个MySQL数据库。把几个MySQL数据库公用的数据做出共享数据，例如购物车，用户对象等等，存在数据结点里面。其他不共享的数据还维持在各自分布的MySQL数据库本身中。

　　2. 集群MySQL中名称概念.(如上图)

　　1)Sql结点(SQL node--上图对应为MySQLd):分布式数据库。包括自身数据和查询中心结点数据.

　　2)数据结点(Data node -- ndbd):集群共享数据(内存中).

　　3)管理服务器(Management Server – ndb_mgmd):集群管理SQL node,Data node.

　　3.配置

　　MySQL-max版本，当然现在MySQL集群系统windonws平台上面不被支持.

　　安装MySQL就不多说了，网上一大堆，简明扼要。

　　A:192.168.1.251 – Data node和Management Server.

　　B:192.168.1.254 – SQL node.

　　当然，你也可以让一个机器同时为3者。

　　A,B my.inf加上：

MySQLD] 
ndbcluster # run NDB engine 
ndb-connectstring=192.168.1.251 # location of MGM node 
# Options for ndbd process: [MySQL_CLUSTER] 
ndb-connectstring=192.168.1.251 # location of MGM node 
A: /var/lib/MySQL-cluster/config.ini [NDBD DEFAULT] 
NoOfReplicas=1 
# Number of replicas DataMemory=80M 
# How much memory to allocate for data storage IndexMemory=18M 
# How much memory to allocate for index storage 
# For DataMemory and IndexMemory, we have used the 
# default values. Since the "world" database takes up 
# only about 500KB, this should be more than enough for 
# this example Cluster setup. # TCP/IP options: [TCP DEFAULT] 
portnumber=2202 # This the default; however, you can use any 
# port that is free for all the hosts in cluster 
# Note: It is recommended beginning with MySQL 5.0 that 
# you do not specify the portnumber at all and simply allow 
# the default value to be used instead # Management process options: [NDB_MGMD] hostname=192.168.1.251 
# Hostname or IP address of MGM node datadir=/var/lib/MySQL-cluster # Directory for MGM node logfiles # Options for data node "A": [NDBD] 
# (one [NDBD] section per data node) hostname=192.168.1.251 
 # Hostname or IP address datadir=/usr/local/MySQL/data 
# Directory for this data node's datafiles 
# SQL node options: [MySQLD] hostname=192.168.1.254 
#[MySQLD] #这个相当于192.168.1.251
