我在测试mysql cluster时出现如下问题请大家帮忙分析一下是怎么回事，我的mysql cluster布署如下，用的是mysql-cluster-gpl-6.2.15-linux-i686-glibc23.tar.gz tar 包
节点管理器：192.168.5.254
存储节点
192.168.5.45
192.168.5.30
sql节点
192.168.5.238
按着官方文档配置好后在节点管理器（192.168.5.254）用show命令显示结果如下：
Connected to Management Server at: localhost:1186

ndb-connectstring=192.168.5.254
[MYSQL_CLUSTER]
ndb-connectstring=192.168.5.254
从节点服务器或存储服务器上nmap管理服务器时看不到1186端口，但telnet 192.168.5.254可以连上，不过在输入get version与get status时没有任何反应（这是我在国外一贴子上看到的）。
最终确定为192.168.5.45上防火墙引起的故障，无法与服务器1186端口通话。
