module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

##Overview

The MySQL module installs, configures, and manages the MySQL service.

##Module Description

The MySQL module manages both the installation and configuration of MySQL as well as extends Pupppet to allow management of MySQL resources, such as databases, users, and grants.

##Backwards Compatibility

This module has just undergone a very large rewrite. As a result it will no longer work with the previous classes and configuration as before. We've attempted to handle backwards compatibility automatically by adding a attempt_compatibility_mode parameter to the main mysql class. If you set this to true it will attempt to map your previous parameters into the new mysql::server class.

###WARNING

This may fail. It may eat your MySQL server. PLEASE test it before running it live. Even if it's just a no-op and a manual comparision. Please be careful!

##Setup

###What MySQL affects

  • MySQL package.
  • MySQL configuration files.
  • MySQL service.

###Beginning with MySQL

If you just want a server installing with the default options you can run include '::mysql::server'. If you need to customize options, such as the root password or /etc/my.cnf settings then you can also include mysql::server and pass in an override hash as seen below:

class { '::mysql::server':
  override_options => { 'mysqld' => { 'max_connections' => '1024' } }
}

##Usage

All interaction for the server is done via mysql::server. To install the client you use mysql::client, and to install bindings you can use mysql::bindings.

###Overrides

The hash structure for overrides in mysql::server is as follows:

override_options = {
  'section' => {
    'item'             => 'thing',
  }
}

For items that you would traditionally represent as:

[section] thing

You can just make an entry like thing => true in the hash. MySQL doesn't care if thing is alone or set to a value, it'll happily accept both.

###Custom configuration

To add custom mysql configuration you can drop additional files into /etc/mysql/conf.d/ in order to override settings or add additional ones (if you choose not to use override_options in mysql::server). This location is hardcoded into the my.cnf template file.

##Reference

###Classes

####Public classes

  • mysql::server: Installs and configures MySQL.
  • mysql::server::account_security: Deletes default MySQL accounts.
  • mysql::server::monitor: Sets up a monitoring user.
  • mysql::server::mysqltuner: Installs MySQL tuner script.
  • mysql::server::backup: Sets up MySQL backups via cron.
  • mysql::bindings: Installs various MySQL language bindings.
  • mysql::client: Installs MySQL client (for non-servers).

####Private classes

  • mysql::server::install: Installs packages.
  • mysql::server::config: Configures MYSQL.
  • mysql::server::service: Manages service.
  • mysql::server::root_password: Sets MySQL root password.

###Parameters

####mysql::server

#####root_password

What is the MySQL root password. Puppet will attempt to set it to this and update /root/.my.cnf.

#####old_root_password

What was the previous root password (REQUIRED if you wish to change the root password via Puppet.)

#####override_options

This is the hash of override options to pass into MySQL. It can be visualized like a hash of the my.cnf file, so that entries look like:

override_options => { 'section' => { 'key' => 'value' } }

For items that you would traditionally represent as:

[section] thing

You can just make an entry like thing => true in the hash. MySQL doesn't care if thing is alone or set to a value, it'll happily accept both.

#####manage_config_file

Should we manage the MySQL configuration file.

#####purge_conf_dir

  options    => ['GRANT'],
  privileges => ['ALL'],
  table      => '*.*',
  user       => 'root@localhost',

#Development

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.

We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.

You can read the complete module contribution guide on the Puppet Labs wiki.
