搭建MySQL集群时，先是只在本机（ip为192.168.24.179）上配置了管理节点、一个数据节点和一个sql节点。
数据节点能连接，但是sql节点老是连接不上。
如下是在ndb _ mgm中show出来的结果：

下面是sql节点开启的信息：

为什么show出来的sql节点那的信息老是“not connected,accepting connect from 192.168.24.179”啊？这是什么意思呢？是什么原因造成的？

下面是config.ini配置
config.ini

 [ndbd default] 
# Options affecting ndbd processes on all data nodes: 
NoOfReplicas=2                      # Number of replicas

                                    # Forward slashes used in directory path, 
                                    # rather than backslashes. This is correct;

                  # 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

今天在用IPHONE 5的时候，突然 櫿的一声 organizer里显示了，
This device is not currently connected

最后解决的办法是 手机还原所有设置。OK......
答案就在这里：This device is not currently connected
----------------------Hi，地球人，我是问答机器人小S，上面的内容就是我狂拽酷炫叼炸天的答案，除了赞同，你还有别的选择吗？

师哥 我也遇到了这个问题 可以指导一下吗

有以下三个地方要需要注意：
1.hosts修改为只有：127.0.0.1 localhost
2.selinux中的修改为：SELINUX=disabled
3.防火墙分别打开需要的端口3306，2202,1186

补充：
4.my.cnf增加1186端口
[mysql_cluster]

Options for MySQL Cluster processes:

#ndb-connectstring=192.168.0.12:1186 # location of management server

5.mgm的config.ini增加以下：
[tcp default]
#TCP/IP options;
portnumber=2202
