(1)启动管理节点，数据节点，SQL节点
在主机10.10.54.86上显示：
ndb_mgm> show
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2   @10.10.54.85  (mysql-5.5.35 ndb-7.2.15, Nodegroup: 0)
id=3   @10.10.54.87  (mysql-5.5.35 ndb-7.2.15, Nodegroup: 0, *)[ndb_mgmd(MGM)]    1 node(s)
id=1   @10.10.54.86  (mysql-5.5.35 ndb-7.2.15)[mysqld(API)]   3 node(s)
id=10  @10.10.54.85  (mysql-5.5.35 ndb-7.2.15)
id=11  @10.10.54.87  (mysql-5.5.35 ndb-7.2.15)
id=12 (not connected, accepting connect from any host)(2)在数据节点上创建数据
即在10.10.54.85上
mysql> create database test1;
mysql> use test1;
mysql> create table test1(age int) engine=ndbcluster default charset=utf8;
mysql> insert into test1 values(88);(3)在管理节点上备份数据
ndb_mgm> start backup 17
Waiting for completed, this may take several minutes
Node 3: Backup 17 started from node 1
Node 3: Backup 17 started from node 1 completedStartGCP: 363 StopGCP: 366#Records: 2063 #LogRecords: 0Data: 52196 bytes Log: 0 bytes(4)在数据节点上删除数据
删除tes1
即在10.10.54.87上
mysql> drop database test1;(5)在数据节点上恢复数据
注意：
必须在删除的那个数据节点上恢复数据
-n 当前存储节点的nodeid
-b 要还原的backupid
-r 数据开关，也就是还原数据了
-m 还原表结构[root@nan87 backup]# ndb_restore -n3 -b17 -c 10.10.54.86 -r -m --backup_path=/data/backup/BACKUP/BACKUP-17
Nodeid = 3
Backup Id = 17
backup path = /data/backup/BACKUP/BACKUP-17
Opening file '/data/backup/BACKUP/BACKUP-17/BACKUP-17.3.ctl'

在10.10.54.85/87上没有数据test1
mysql> show databases;
+--------------------+

7 rows in set (0.18 sec)(7)需要创建数据库test1
即在10.10.54.85/87上
mysql> create database test1;
mysql> show databases;
