MySQL Cluster: cannot start the management node

That is weird. Two things I would check that can cause problems (in my experience):

1> make sure iptables is not running

2> make sure selinux is disabled (or permissive)

...at least in the beginning.

You can also try watching the network to see if things are going as suggested although I've never done this for mysql cluster specifically:

tcpdump -s0 -A -i any port 63132

Finally,

I noticed you forced a port number in the ndb mgmt config but not in the node configs. Is that going to be required info on the nodes? Try commenting that out in the mgmt node.

Your management configuration seems fine to me. It sounds like ndb_mgmd didn't quite die or there is a problem with the contents in the /var/lib/mysql-cluster directory on the management server.

You might also want to make sure that ndb_mgmd isn't starting automatically, like through some startup script in /etc/init.d/.

To try and resolve the issue, I'd start with these steps first.

Since you are just getting started and don't have any real data yet.

1. Kill any left over ndb_mgmd processes with: killall ndb_mgmd or by rebooting if killall doesn't help.
2. Completely delete everything within /var/lib/mysql-cluster: rm -Rf /var/lib/mysql-cluster/*
3. Start the cluster process again: ndb_mgmd -f /etc/config.ini --initial

4. Verify that ndb_mgmd is listening with netstat

   $> netstat -tlpn

Update

Here is a Quick Start guide from Oracle with all nodes, management, mysql and data running on one server.
