mysql cluster数据节点启不了

[root@NDB1 bin]# ./ndbd --initial
Unable to connect with connect string: nodeid=0,localhost:1186
Retrying every 5 seconds. Attempts left: 12 11 10 9 8 7 6 5 4 3 2 1, failed.
2016-04-03 06:33:35 [ndbd] ERROR -- Could not connect to management server, error: ''

MGM节点配置如下:
vi config.ini

[ndbd default]

NoOfReplicas=2
DataMemory=200M
IndexMemory=30M

[ndb_mgmd]
NodeId=1
hostname=192.168.137.102
datadir=/var/lib/mysql-cluster/_

[ndbd]
NodeId=2
hostname=192.168.137.101
datadir=/usr/local/mysql/data

[ndbd]
NodeId=3
hostname=192.168.137.103
datadir=/usr/local/mysql/data

[mysqld]
NodeId=4
hostname=192.168.137.104

[mysqld]
NodeId=5
hostname=192.168.137.105

[mysqld]
NodeId=6

MGM启动正常:
[root@MGM bin]# ./ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: localhost:1186

Cluster Configuration

[ndbd(NDB)] 2 node(s)
id=2 (not connected, accepting connect from 192.168.137.101)
id=3 (not connected, accepting connect from 192.168.137.103)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.137.102 (mysql-5.6.28 ndb-7.4.10)

[mysqld(API)] 3 node(s)

id=5 (not connected, accepting connect from 192.168.137.105)
id=6 (not connected, accepting connect from any host)

但启动数据节点报错:
[root@NDB1 bin]# ./ndbd --initial
Unable to connect with connect string: nodeid=0,localhost:1186
Retrying every 5 seconds. Attempts left: 12 11 10 9 8 7 6 5 4 3 2 1, failed.
2016-04-03 06:33:35 [ndbd] ERROR -- Could not connect to management server, error: ''

在数据节点connect管理节点没有问题:
[root@NDB1 bin]# ./ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> connect 192.168.137.102
Connected to Management Server at: 192.168.137.102:1186

数据节点指定管理节点地址登录成功了,在管理端也能使用ndb_mgm工具做停止,但不能用ndb_mgm做启动,不知道为何
ndbd -c 192.168.137.102

ndb_mgm> 2 stop
