NuoDB module for Puppet

Archived

This has not been in active use in use since 2017.

---

Overview

Installs and configures NuoDB database.

Requirements

• Java 8 or higher - This module will by default use puppetlabs/java module to install Java it is requested not manage Java.
• Disable Transparent Hugepages (THP) on Linux - This module will by default use alexharvey/disable_transparent_hugepage module to install Java it is requested not manage THP.

Usage

Installation using minimal parameters

This module can install and configure NuoDB with a minimal set of parameters.

It is highly recommended that you at least set your own domainPassword to make sure your database does not use the default password (ch@ngeMe) providedy this module.

If you are not using Hiera, to setup NuoDB with the default parameters, just include the module.

include ::nuodb

Or to set any parameters as follows.

class { ::nuodb:
  config_overrides => {
    domainPassword => 'mySuperSecretPassword',
  },
}

With Hiera

All the configuration data required for this module can be prprovidedy Hiera, so just including the module should suffice in the in the Puppet code.

include ::nuodb

In Hiera, it is rerecommendedo at least set the following.

nuodb::config_overrides:
  domainPassword: 'mySuperSecretPassword'

Installing on RedHat/CentOS 7

There is a known issue in disabling THP on RedHat/CentOS unless the service_provider is specified when including the alexharv074/puppet-disable_transparent_hugepage module.

class { ::disable_transparent_hugepage:
  service_provider => 'redhat',
}

class { ::nuodb:
  config_overrides => {
    domainPassword => 'mySuperSecretPassword',
  },
}

With Hiera

include ::disable_transparent_hugepage:

include ::nuodb

disable_transparent_hugepage::service_provider: redhat

nuodb::config_overrides:
  domainPassword: mySuperSecretPassword

Install NuoDB without installing Java, if Java is already installed

class { ::nuodb:
  manage_java => false,
}

With Hiera

include ::nuodb

nuodb::manage_java: false

Setting properties in default.properties file

When using the config_overrides parameter, this will get merged with config_defaults to determine the final set of properties to set, where values defined in config_overrides will always win.

For example, to set the peer propoerty in the default.properties file in addition to all the defaults provided by the module,

class { ::nuodb:
  config_overrides => {
    domainPassword => 'mySuperSecretPassword',
    peer           => '192.168.1.20',
  },
}

With Hiera

include ::nuodb

nuodb::config_overrides:
  domainPassword: mySuperSecretPassword
  peer: 192.168.1.20

To not use any default values provided by this module for the default.properties file

To prevent using the provided default values for the default.properties file, redefine the config_defaults hash instead of using config_overrides.

class { ::nuodb:
  config_defaults => {
    domainPassword => 'superSecretDomainPassword',
  },
}

With Hiera

include ::nuodb

nuodb::config_defaults:
  domainPassword: superSecretDomainPassword

Creating a domain administrator

class { ::nuodb:
  domain_administrators => {
    'domainadmin1' => {
      ensure   => present,
      password => 'domainadmin1password',
    },
  },
}

With Hiera

include ::nuodb

nuodb::domain_administrators:
  domainadmin1:
    ensure: present
    password: domainadminpassword1

Creating a database

class { ::nuodb:
  databases => {
    'testdb1' => {
      ensure       => present,
      template     => 'Multi Host',
      dba_username => 'dba1',
      dba_password => 'secret1',
    },
  },
}

With Hiera

include ::nuodb

nuodb::databases:
  testdb1:
    ensure: present
    template: Multi Host
    dba_username: dba1
    dba_password: secret1
