關於MySQL簇問題的成功解決

我在測試MySQL cluster時出現如下問題請大家幫忙分析一下是怎麼回事，我的mysql cluster布署如下，用的是mysql-cluster-gpl-6.2.15-linux-i686-glibc23.tar.gz tar 包
節點管理器：192.168.5.254
儲存節點
192.168.5.45
192.168.5.30
sql節點
192.168.5.238
按著官方文檔配置好後在節點管理器（192.168.5.254）用show命令顯示結果如下：
Connected to Management Server at: localhost:1186
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2 @192.168.5.45 (mysql-5.1.23 ndb-6.2.15, starting, Nodegroup: 0)
id=3 @192.168.5.30 (mysql-5.1.23 ndb-6.2.15, starting, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1 (mysql-5.1.23 ndb-6.2.15)

[mysqld(API)] 1 node(s)
id=4 (not connected, accepting connect from 192.168.5.23

從節點伺服器或儲存伺服器上nmap管理伺服器時看不到1186連接埠，但telnet 192.168.5.254可以連上，不過在輸入get version與get status時沒有任何反應（這是我在國外一貼子上看到的）。

最終確定為192.168.5.45上防火牆引起的故障，無法與伺服器1186連接埠通話。
