Mysql and NDB are not connected
<p>i am new in my mysql and i try to configure and run a cluster. i have done the installation and the config , my.cnf .
We can see the manager of cluster and the data node correct :</p>

<p>MySQL Cluster Management Server mysql-5.7.13 ndb-7.5.3</p>

<p>2016-10-05 16:48:55 [ndbd] INFO     -- Angel connected to '10.1.4.39:1186'
2016-10-05 16:48:55 [ndbd] INFO     -- Angel allocated nodeid: 2</p>

<p>All okay but then i go check my cluster and it show that:</p>

<pre><code>-- NDB Cluster -- Management Client --
ndb_mgm&gt; show
Connected to Management Server at: localhost:1186
Cluster Configuration
---------------------
[ndbd(NDB)]     2 node(s)
id=2    @10.1.4.41  (mysql-5.7.13 ndb-7.5.3, Nodegroup: 0, *)
id=3    @10.1.4.42  (mysql-5.7.13 ndb-7.5.3, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1    @10.1.4.39  (mysql-5.7.13 ndb-7.5.3)

[mysqld(API)]   1 node(s)
id=4 (not connected, accepting connect from manager.mysql.cluster)
</code></pre>

<p>why the mysqld is not connected ? That output is normal ?
When i connect to mysql doesnt show the its connected to ndb as it should </p>
