Starting multiple ndbd instances on the same machine

[Robert McHugh]

I know this may sound a little strange. But for the purposes of testing I would like to run a system using the following setup:

1 management node
2 API nodes
2 Database nodes

Due to a lack of resources I would like to do this on the same computer. But every time I try to start the second ndbd it seems to work (ndbd comes back with no messages). However when I do a "show" in the management console it's not there.

Any ideas?

my config.ini looks like this

[NDBD DEFAULT]
NoOfReplicas=1

[MYSQLD DEFAULT]
[NDB_MGMD DEFAULT]
[TCP DEFAULT]

[NDB_MGMD]
HostName=192.168.10.161

[NDBD]
HostName=192.168.10.161
DataDir=/var/lib/mysql-cluster

[NDBD]
HostName=192.168.10.161
DataDir=/var/lib/mysql-cluster
