mysql ndb cluster add data node - mysql

Question

This is my config.ini file
options affecting ndbd processes on all data nodes:
[ndbd default]
NoOfReplicas=1 # 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 that you do not specify the port
# number at all and allow the default value to be used instead
Management process options:
[ndb_mgmd]
hostname=192.168.1.10 # Hostname or IP address of management node
datadir=/var/lib/mysql-cluster # Directory for management node log files
Options for data node "A":
[ndbd]
# (one [ndbd] section per data node)
hostname=192.168.1.10 # Hostname or IP address
datadir=/usr/local/mysql/data # Directory for this data node's data files
Options for data node "B":
[ndbd]
hostname=192.168.0.20 # Hostname or IP address
datadir=/usr/local/mysql/data # Directory for this data node's data files
SQL node options:
[mysqld]
hostname=192.168.1.10 # Hostname or IP address
# (additional mysqld connections can be
# specified for this node for various
# purposes such as running ndb_restore)
I want to specify second data node on 192.168.0.20 server.
What changes do i need to do on 192.168.0.20? It is a very low end machine so, I want don't want mysqld to run there.
can anyone provide any input on this.

If you use http://www.severalnines.com/config/index.php to create configurations files, and ask it to send it to you as an e-mail, you will get several scripts, including add_node.sh, which might be what you need.
