错误：
[root@localhost ~]# ndbd
2010-04-15 17:02:20 [ndbd] INFO     -- Unable to alloc node id
2010-04-15 17:02:20 [ndbd] INFO     -- Error : Could not alloc node id at 192.168.100.118 port 1186: No free node id found for ndbd(NDB).
error=2350
2010-04-15 17:02:20 [ndbd] INFO     -- Error handler restarting system

管理节点（好像正常啊）：
[root@localhost mysql-cluster]# ndb_mgm

ndb_mgm> show

管理节点，配置文件

[root@localhost mysql-cluster]# more config.ini
[NDBD DEFAULT]
NoOfReplicas=2    # Number of replicas
DataMemory=80M    # How much memory to allocate for data storage
IndexMemory=18M   # How much memory to allocate for index storage
MaxNoOfOrderedIndexes= 512

                  # 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]
id=0                     
hostname=192.168.100.118           # Hostname or IP address of MGM node
datadir=/var/lib/mysql-cluster  # Directory for MGM node logfiles

# Options for data node "A":
[NDBD]
id=2                          
                                # (one [NDBD] section per data node)
hostname=192.168.100.119           # Hostname or IP address
datadir=/usr/local/mysql/data   # Directory for this data node's datafiles

# Options for data node "B":
[NDBD]
id=3                          
hostname=192.168.100.120           # Hostname or IP address
datadir=/usr/local/mysql/data   # Directory for this data node's datafiles

[MYSQLD]

存储和sql节点在一起，配置如下
datadir=/usr/local/mysql/data/       //脮脌要脫鹿脺铆碌茫config.ini脧同
  ndbcluster
  ndb-connectstring=192.168.100.118
  [ndbd]
  connect-string=192.168.100.118
  [mysql_cluster]
  ndb-connectstring=192.168.100.118
  [ndb_mgm]
  connect-string=192.168.100.118
  [ndb_mgmd]
  config-file=/var/lib/mysql-cluster/config.ini  

数据不能同步，还报上面的错误！困惑啊！而且SQL节点也少一个呀！
