[mysqld]
ndbcluster # run NDB storage engine
[mysql_cluster]
ndb-connectstring=192.168.0.10 # location of management server

 

Configuring the management node:
shell> mkdir /var/lib/mysql-cluster
shell> cd /var/lib/mysql-cluster
shell> vi config.ini

[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

[tcp default]
# TCP/IP options:
portnumber=2202 # This the default; however, you can use any

[ndb_mgmd]
