//配置文件
(1)在data节点和storage节点，都需要my.cnf配置文件。ndb-connectstring告诉节点可以找到management(管理节点),ndbcluster 告诉节点使用ndbcluster存储引擎。
(2)在management节点需要config.ini配置文件，在数据节点有多少复制维护，分配多少内存给数据和索引。怎么找到数据节点，怎么保存数据到硬盘在每个数据节点上，怎么找到数据节点。
(3)[root@appdb /]#vim /etc/my.cnf
[mysqld]
#run NDB storage engine
ndbcluster
#location of management server
ndb-connectstring = 192.168.70.161
#options for ndbd process:
[ndb_cluster]
#location of management server
ndb-connectstring = 192.168.70.161
配置management节点，首先创建一个目录(/var/lib/mysql-cluster)，然后在改目录下创建config.ini
[root@appdb /]#mkdir -pv /var/lib/mysql-cluster
[root@appdb /]#cd /var/lib/mysql-cluster/
[root@appdb /]#vim config.ini
