To get started with MySQL Cluster, read MySQL Cluster Quick Start at
http://dev.mysql.com/downloads/cluster/
Default configuration files have been created inside:
#{var}/mysql-cluster
Note that in a production system there are other parameters
that you would set to tune the configuration.
Set up databases to run AS YOUR USER ACCOUNT with:
unset TMPDIR
mysql_install_db --verbose --user=`whoami` --basedir="#{opt_prefix}" --datadir=#{var}/mysql-cluster/mysqld_data --tmpdir=/tmp
For a first cluster, you may start with a single MySQL Server (mysqld),
a pair of Data Nodes (ndbd) and a single management node (ndb_mgmd):
ndb_mgmd -f #{var}/mysql-cluster/conf/config.ini --initial --configdir=#{var}/mysql-cluster/conf/
ndbd -c localhost:1186
ndbd -c localhost:1186
mysqld --defaults-file=/usr/local/var/mysql-cluster/conf/my.cnf &
mysql -h 127.0.0.1 -P 5000 -u root -p
(Leave the password empty and press Enter)
create database clusterdb;
use clusterdb;
create table simples (id int not null primary key) engine=ndb;
insert into simples values (1),(2),(3),(4);
select * from simples;
To shutdown everything:
mysqladmin -u root -p shutdown
ndb_mgm -e shutdown
