Criando my.cnf 

cd /etc/
mv my.cnf my.cnf.disabled
ln -sf /databases/my_cluster/conf/my.cnf .

Configurando a instância

cd /usr/local/mysql/scripts
./mysql_install_db --no-defaults --datadir=/databases/my_cluster/mysqld_data/ --basedir=/usr/local/mysql/scripts/

cd /databases/
chown mysql:mysql my_cluster/ -R

Configurando a API(MySQL)

cd /etc
mv my.cnf my.cnf-original
ln -sf /databases/my_cluster/conf/my.cnf .
/etc/init.d/mysql start
mysql -h 127.0.0.1 -P 5000 -u root

Start do Gerenciado do Cluster

ndb_mgmd -f /databases/my_cluster/conf/config.ini  --initial \
--configdir=/databases/my_cluster/conf/

Start do DataNode

ndbd -c localhost:1186
ndbd -c localhost:1186

Verificando

ndb_mgm -e show
