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
