Is mysqld connecting?

[Alex Mace]

I'm trying to setup a test cluster here to catch any gotchas I might come across in a production environment. At the moment I've got the management server setup and running fine, and I can get data nodes to connect to it fine.

Seemingly though, there is something that mysqld doesn't like because the Management node doesn't seem to show it is connected. This is the output I get from the management client -

-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: 10.1.1.79:1186
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2 (not connected, accepting connect from 10.1.1.78)
id=3 @10.1.1.77 (Version: 5.0.15, starting, Nodegroup: 0, Master)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @10.1.1.79 (Version: 5.0.15)

[mysqld(API)] 2 node(s)
id=4 (not connected, accepting connect from any host)
id=5 (not connected, accepting connect from any host)

ndb_mgm>

No mysqlds. However, when I issue a shutdown command, the .err log for the mysqld server shows that it's lost it's connection to the management server, and is going to try to reconnect. Which would seem to suggest that it is connected. Is there something I'm missing here?

Here's my my.cnf

[mysqld]
ndbcluster
ndb-connectstring=10.1.1.79
[mysql_cluster]
ndb-connectstring=10.1.1.79

and my config.ini

[NDBD DEFAULT]
NoOfReplicas=2
DataMemory=500M
IndexMemory=100M
[MYSQLD DEFAULT]
[NDB_MGMD DEFAULT]
[TCP DEFAULT]
[NDB_MGMD]
HostName=10.1.1.79
[NDBD]
HostName=10.1.1.78
DataDir=/var/lib/mysql-cluster
[NDBD]
HostName=10.1.1.77
DataDir=/var/lib/mysql-cluster
[MYSQLD]
[MYSQLD]

Any ideas please?
