MySQL Cluster has been using the default port 2200 for the management
server in the past. This has not been a port that is "free to use".
We have now gotten a port number for MySQL Cluster assigned to us from
IANA which is 1186. From 4.1.8 this will be the default port number. If
you have specified a port for the management server explicitly in your
config files you will not be affected by this. E.g.
[ndb_mgmd] or [mgm]
mysqld and all tools will default connect to this port (1186) so you
should not experience a problem with this change, unless you need to
open up firewalls or similar for this port.
To make as small changes as possible, TCP portnumbers for the internal
cluster communication will default be allocated starting at 2202 as they
have been before. However it is _highly_ recommended that you specify
this number explicitly in your config files:
