MySQL Cluster Configuration — Basic Example
To support MySQL Cluster, you will need to update
my.cnf
as shown in the following example.
You may also specify these parameters on the command line when
invoking the executables.
Note
The options shown here should not be confused with those that
are used in config.ini
global
configuration files. Global configuration options are
discussed later in this section.
# my.cnf
# example additions to my.cnf for MySQL Cluster
# (valid in MySQL 5.1)
# enable ndbcluster storage engine, and provide connectstring for
# management server host (default port is 1186)
[mysqld]
ndbcluster
ndb-connectstring=ndb_mgmd.mysql.com
# provide connectstring for management server host (default port: 1186)
[ndbd]
connect-string=ndb_mgmd.mysql.com
# provide connectstring for management server host (default port: 1186)
[ndb_mgm]
connect-string=ndb_mgmd.mysql.com
# provide location of cluster configuration file
[ndb_mgmd]
config-file=/etc/config.ini
(For more information on connectstrings, see
Section 3.2.3, “The MySQL Cluster Connectstring”
.)
# my.cnf
# example additions to my.cnf for MySQL Cluster
# (will work on all versions)
# enable ndbcluster storage engine, and provide connectstring for management
# server host to the default port 1186
[mysqld]
ndbcluster
ndb-connectstring=ndb_mgmd.mysql.com:1186
Important
Once you have started a mysqld
process with
the NDBCLUSTER
and
ndb-connectstring
parameters in the
[mysqld]
in the my.cnf
file as shown previously, you cannot execute any
CREATE TABLE
or
ALTER TABLE
statements without
having actually started the cluster. Otherwise, these
statements will fail with an error. This is by
design
.
You may also use a separate [mysql_cluster]

To familiarize you with the basics, we will describe the simplest
possible configuration for a functional MySQL Cluster. After this,
you should be able to design your desired setup from the
information provided in the other relevant sections of this
chapter.
