To get started with MySQL Cluster, read MySQL Cluster Quick Start at
https://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.
MySQL is configured to only allow connections from localhost by default
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=#{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
