Module Description

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

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

Setup

Beginning with MySQL

If you want a server installed 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 must also pass in an override hash:

class { '::mysql::server':
  root_password           => 'strongpassword',
  remove_default_accounts => true,
  override_options        => $override_options
}

See Customizing Server Options below for examples of the hash structure for $override_options`.

Usage

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

Customizing Server Options

The hash structure for overrides in mysql::server can be structured like a hash in the my.cnf file, so:

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

For items that you would traditionally represent as

[section]
thing = X

you can make an entry like thing => true, thing => value, or thing => " in the hash. Alternatively, you can pass an array, as thing => ['value', 'value2'], or list each thing => value separately on separate lines.

MySQL doesn't care if 'thing' is alone or set to a value; it happily accepts both. To keep an option out of the my.cnf file --- e.g., when using override_options to revert to a default value --- you can pass thing => undef.

If an option needs multiple instances, you can pass an array. For example,

$override_options = {
  'mysqld' => {
    'replicate-do-db' => ['base1', 'base2'],
  }
}

produces

[mysqld]
replicate-do-db = base1
replicate-do-db = base2

Creating a database

To use mysql::db to create a database with a user and assign some privileges:

mysql::db { 'mydb':
  user     => 'myuser',
  password => 'mypass',
  host     => 'localhost',
  grant    => ['SELECT', 'UPDATE'],
}

Or to use a different resource name with exported resources:

 @@mysql::db { "mydb_${fqdn}":
  user     => 'myuser',
  password => 'mypass',
  dbname   => 'mydb',
  host     => ${fqdn},
  grant    => ['SELECT', 'UPDATE'],
  tag      => $domain,
}

Then you can collect it on the remote DB server:

Mysql::Db <<| tag == $domain |>>

If you set the sql param to a file when creating a database, the file gets imported into the new database.

For large sql files, you should raise the $import_timeout parameter, set by default to 300 seconds.

mysql::db { 'mydb':
  user     => 'myuser',
  password => 'mypass',
  host     => 'localhost',
  grant    => ['SELECT', 'UPDATE'],
  sql      => '/path/to/sqlfile',
  import_timeout => 900,
}

Custom Configuration

To add custom MySQL configuration, drop additional files into includedir. Dropping files into includedir allows you to override settings or add additional ones, which is helpful if you choose not to use override_options in mysql::server. The includedir location is by default set to /etc/mysql/conf.d.

Working with an existing server

You can use the MySQL module to instantiate databases and users on an existing MySQL server. For this to work, you need an appropriate .my.cnf in root's home directory containing the remote server address and credentials. For example:

[client]
user=root
host=localhost
password=secret

When working with a remote server, do not use the mysql::server class in your Puppet manifests.

Using passwords

As well as inputting passwords as plain text you can input them as hashes. For example:

mysql::db { 'mydb':
  user     => 'myuser',
  password => '*6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4',
  host     => 'localhost',
  grant    => ['SELECT', 'UPDATE'],
}

Parameters

mysql::server

`create_root_user`

Specify whether root user should be created. Valid values are 'true', 'false'. Defaults to 'true'.

This is useful for a cluster setup with Galera. The root user has to be created only once. create_root_user can be set to 'true' on one node while it is set to 'false' on the remaining nodes.

`create_root_my_cnf`

If set to 'true', creates /root/.my.cnf. Valid values are 'true', 'false'. Defaults to 'true'.

create_root_my_cnf allows creation of /root/.my.cnf independently of create_root_user. This can be used for a cluster setup with Galera where you want /root/.my.cnf to exist on all nodes.

`root_password`

The MySQL root password. Puppet attempts to set the root password and update /root/.my.cnf with it.

This is required if create_root_user or create_root_my_cnf are 'true'. If root_password is 'UNSET', then create_root_user and create_root_my_cnf are assumed to be false --- that is, the MySQL root user and /root/.my.cnf are not created.

Password changes are supported; however, the old password must be set in /root/.my.cnf. Effectively, Puppet uses the old password, configured in /root/my.cnf, to set the new password in MySQL, and then updates /root/.my.cnf with the new password.

`old_root_password`

This parameter no longer does anything. It exists only for backwards compatibility. See the root_password parameter above for details on changing the root password.

`override_options`

The hash of override options to pass into MySQL. Structured like a hash in the my.cnf file:

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

See Customizing Server Options above for usage details.

`config_file`

`manage_config_file`

mysql_grant

mysql_grant creates grant permissions to access databases within MySQL. To create grant permissions to access databases with MySQL, use it you must create the title of the resource as shown below, following the pattern of username@hostname/database.table:

Facts

`mysql_version`

Determines the MySQL version by parsing the output from mysql --version

`mysql_server_id`

Generates a unique id, based on the node's MAC address, which can be used as server_id. This fact will always return 0 on nodes that have only loopback interfaces. Because those nodes aren't connected to the outside world, this shouldn't cause any conflicts.

Limitations

This module has been tested on:

RedHat Enterprise Linux 5, 6, 7
Debian 6, 7
CentOS 5, 6, 7
Ubuntu 10.04, 12.04, 14.04
Scientific Linux 5, 6
SLES 11

Testing on other platforms has been minimal and cannot be guaranteed.

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.

Check out our the complete module contribution guide.
