Comment 2 for bug 450837

Here is an example of the configuration file for the mgmt node (/etc/mysql/config.ini):

# Options affecting ndbd processes on all data nodes:
[ndbd default]
NoOfReplicas=2 # Number of replicas
DataMemory=80M # How much memory to allocate for data storage
IndexMemory=18M # How much memory to allocate for index storage
                  # For DataMemory and IndexMemory, we have used the
                  # default values. Since the "world" database takes up
                  # only about 500KB, this should be more than enough for
                  # this example Cluster setup.

# TCP/IP options:
[tcp default]
portnumber=2202 # This the default; however, you can use any
                  # port that is free for all the hosts in the cluster
                  # Note: It is recommended beginning with MySQL 5.0 that
                  # you do not specify the portnumber at all and simply allow
                  # the default value to be used instead

# Management process options:
[ndb_mgmd]
hostname=192.168.0.10 # Hostname or IP address of MGM node
datadir=/var/lib/mysql-cluster # Directory for MGM node log files

# Options for data node "A":
[ndbd]
                                # (one [ndbd] section per data node)
hostname=192.168.0.30 # Hostname or IP address
datadir=/usr/local/mysql/data # Directory for this data node's data files

# Options for data node "B":
[ndbd]
hostname=192.168.0.40 # Hostname or IP address
datadir=/usr/local/mysql/data # Directory for this data node's data files

# SQL node options:
[mysqld]
hostname=192.168.0.20 # Hostname or IP address
                                # (additional mysqld connections can be
                                # specified for this node for various
                                # purposes such as running ndb_restore)
