Module Description

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

This 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

To install a server with the default options:

include '::mysql::server'.

To customize options, such as the root password or /etc/my.cnf settings, you must also pass in an override hash:

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

See Customize 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.

Customize server options

To define server options, structure a hash structure of overrides in mysql::server. This hash resembles a hash in the my.cnf file:

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

For options that you would traditionally represent in this format:

[section]
thing = X

Entries can be created as 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 individual lines.

You can pass a variable in the hash without setting a value for it; the variable would then use MySQL's default settings. To exclude an option from the my.cnf file --- for example, when using override_options to revert to a default value --- pass thing => undef.

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

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

produces

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

To implement version specific parameters, specify the version, such as [mysqld-5.5]. This allows one config for different versions of MySQL.

Create a database

To create a database with a user and some assigned privileges:

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

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 parameter to a file when creating a database, the file is imported into the new database.

For large sql files, increase the import_timeout parameter, which defaults to 300 seconds.

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

Customize configuration

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

Work with an existing server

To instantiate databases and users on an existing MySQL server, you need a .my.cnf file in root's home directory. This file must specify the remote server address and credentials. For example:

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

This module uses the mysqld_version fact to discover the server version being used. By default, this is set to the output of mysqld -V. If you're working with a remote MySQL server, you may need to set a custom fact for mysqld_version to ensure correct behaviour.

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

Specify passwords

In addition to passing passwords as plain text, you can input them as hashes. For example:

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

Install Percona server on CentOS

This example shows how to do a minimal installation of a Percona server on a CentOS system. This sets up the Percona server, client, and bindings (including Perl and Python bindings). You can customize this usage and update the version as needed.

This usage has been tested on Puppet 4.4 / CentOS 7 / Percona Server 5.7.

Note: The installation of the yum repository is not part of this package and is here only to show a full example of how you can install.

yumrepo { 'percona':
  descr    => 'CentOS $releasever - Percona',
  baseurl  => 'http://repo.percona.com/centos/$releasever/os/$basearch/',
  gpgkey   => 'http://www.percona.com/downloads/percona-release/RPM-GPG-KEY-percona',
  enabled  => 1,
  gpgcheck => 1,
}

class {'mysql::server':
  package_name     => 'Percona-Server-server-57',
  package_ensure   => '5.7.11-4.1.el7',
  service_name     => 'mysql',
  config_file      => '/etc/my.cnf',
  includedir       => '/etc/my.cnf.d',
  root_password    => 'PutYourOwnPwdHere',
  override_options => {
    mysqld => {
      log-error => '/var/log/mysqld.log',
      pid-file  => '/var/run/mysqld/mysqld.pid',
    },
    mysqld_safe => {
      log-error => '/var/log/mysqld.log',
    },
  }
}

# Note: Installing Percona-Server-server-57 also installs Percona-Server-client-57.
# This shows how to install the Percona MySQL client on its own
class {'mysql::client':
  package_name   => 'Percona-Server-client-57',
  package_ensure => '5.7.11-4.1.el7',
}

# These packages are normally installed along with Percona-Server-server-57
# If you needed to install the bindings, however, you could do so with this code
class { 'mysql::bindings':
  client_dev_package_name   => 'Percona-Server-shared-57',
  client_dev_package_ensure => '5.7.11-4.1.el7',
  client_dev                => true,
  daemon_dev_package_name   => 'Percona-Server-devel-57',
  daemon_dev_package_ensure => '5.7.11-4.1.el7',
  daemon_dev                => true,
  perl_enable               => true,
  perl_package_name         => 'perl-DBD-MySQL',
  python_enable             => true,
  python_package_name       => 'MySQL-python',
}

Install MariaDB on Ubuntu

Optional: Install the MariaDB official repo

In this example, we'll use the latest stable (currently 10.1) from the official MariaDB repository, not the one from the distro repository. You could instead use the package from the Ubuntu repository. Make sure you use the repository corresponding to the version you want.

Note: sfo1.mirrors.digitalocean.com is one of many mirrors available. You can use any official mirror.

include apt

apt::source { 'mariadb':
  location => 'http://sfo1.mirrors.digitalocean.com/mariadb/repo/10.1/ubuntu',
  release  => $::lsbdistcodename,
  repos    => 'main',
  key      => {
    id     => '199369E5404BD5FC7D2FE43BCBCB082A1BB943DB',
    server => 'hkp://keyserver.ubuntu.com:80',
  },
  include => {
    src   => false,
    deb   => true,
  },
}

Install the MariaDB server

This example shows MariaDB server installation on Ubuntu Trusty. Adjust the version and the parameters of my.cnf as needed. All parameters of the my.cnf can be defined using the override_options parameter.

The folders /var/log/mysql and /var/run/mysqld are created automatically, but if you are using other custom folders, they should exist as prerequisites for this code.

All the values set here are an example of a working minimal configuration.

Specify the version of the package you want with the package_ensure parameter.

class {'::mysql::server':
  package_name     => 'mariadb-server',
  package_ensure   => '10.1.14+maria-1~trusty',
  service_name     => 'mysql',
  root_password    => 'AVeryStrongPasswordUShouldEncrypt!',
  override_options => {
    mysqld => {
      'log-error' => '/var/log/mysql/mariadb.log',
      'pid-file'  => '/var/run/mysqld/mysqld.pid',
    },
    mysqld_safe => {
      'log-error' => '/var/log/mysql/mariadb.log',
    },
  }
}

# Dependency management. Only use that part if you are installing the repository
# as shown in the Preliminary step of this example.
Apt::Source['mariadb'] ~>
Class['apt::update'] ->
Class['::mysql::server']

Install the MariaDB client

This example shows how to install the MariaDB client and all of the bindings at once. You can do this installation separately from the server installation.

Specify the version of the package you want with the package_ensure parameter.

class {'::mysql::client':
  package_name    => 'mariadb-client',
  package_ensure  => '10.1.14+maria-1~trusty',
  bindings_enable => true,
}

Parameters

mysql::server

`create_root_user`

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. You can set this parameter true on one node and set it to false on the remaining nodes.

`create_root_my_cnf`

Whether to create /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. You can use this 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`

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

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

See Customize Server Options above for usage details.

`config_file`

Valid values are true, false.

Defaults to false.

`restart`

Whether the service should be restarted when things change.

Valid values are true, false.

Defaults to false.

`root_group`

The name of the group used for root. Can be a group name or a group ID. See more about the group file attribute.

Valid values are true, false.

Defaults to true.

`service_manage`

Specifies whether the service should be managed.

Valid values are true, false.

Defaults to true.

Command to read the sqlfile for importing the database. Useful for compressed sqlfiles. For example, you can use 'zcat' for .gz files.

Defaults to 'cat'.

Types

mysql_database

mysql_database creates and manages databases within MySQL.

`ensure`

Whether the resource is present.

Valid values are 'present', 'absent'.

Defaults to 'present'.

`name`

The name of the MySQL database to manage.

`charset`

The CHARACTER SET setting for the database.

Defaults to ':utf8'.

`collate`

The COLLATE setting for the database.

Defaults to ':utf8_general_ci'.

mysql_user

Creates and manages user grants within MySQL.

mysql_user { 'root@127.0.0.1':
  ensure                   => 'present',
  max_connections_per_hour => '0',
  max_queries_per_hour     => '0',
  max_updates_per_hour     => '0',
  max_user_connections     => '0',
}

You can also specify an authentication plugin.

mysql_user{ 'myuser'@'localhost':
  ensure                   => 'present',
  plugin                   => 'unix_socket',
}

TLS options can be specified for a user.

mysql_user{ 'myuser'@'localhost':
  ensure                   => 'present',
  tls_options              => ['SSL'],
}

`name`

The name of the user, as 'username@hostname' or username@hostname.

`password_hash`

The user's password hash of the user. Use mysql_password() for creating such a hash.

`max_user_connections`

Maximum concurrent connections for the user.

Must be an integer value.

A value of '0' specifies no (or global) limit.

`max_connections_per_hour`

Maximum connections per hour for the user.

Must be an integer value.

A value of '0' specifies no (or global) limit.

`max_queries_per_hour`

Maximum queries per hour for the user.

Must be an integer value.

A value of '0' specifies no (or global) limit.

`max_updates_per_hour`

Maximum updates per hour for the user.

Must be an integer value.

A value of '0' specifies no (or global) limit.

`tls_options`

SSL-related options for a MySQL account, using one or more tls_option values. 'NONE' specifies that the account has no TLS options enforced, and the available options are 'SSL', 'X509', 'CIPHER cipher', 'ISSUER issuer', 'SUBJECT subject'; as stated in the MySQL documentation.

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:

mysql_grant { 'root@localhost/*.*':
  ensure     => 'present',
  options    => ['GRANT'],
  privileges => ['ALL'],
  table      => '*.*',
  user       => 'root@localhost',
}

It is possible to specify privileges down to the column level:

mysql_grant { 'root@localhost/mysql.user':
  ensure     => 'present',
  privileges => ['SELECT (Host, User)'],
  table      => 'mysql.user',
  user       => 'root@localhost',
}

To revoke GRANT privilege specify ['NONE'].

`ensure`

Whether the resource is present.

Valid values are 'present', 'absent'.

Defaults to 'present'.

`name`

Name to describe the grant. Must in a 'user/table' format.

`privileges`

Privileges to grant the user.

`table`

The table to which privileges are applied.

`user`

User to whom privileges are granted.

`options`

MySQL options to grant. Optional.

mysql_plugin

mysql_plugin can be used to load plugins into the MySQL Server.

mysql_plugin { 'auth_socket':
  ensure     => 'present',
  soname     => 'auth_socket.so',
}

`ensure`

Whether the resource is present.

Valid values are 'present', 'absent'.

Defaults to 'present'.

`name`

The name of the MySQL plugin to manage.

`soname`

The library file name.

`mysql_datadir`

Initializes the MySQL data directory with version specific code. Pre MySQL 5.7.6 it uses mysql_install_db. After MySQL 5.7.6 it uses mysqld --initialize-insecure.

Insecure initialization is needed, as mysqld version 5.7 introduced 'secure by default' mode. This means MySQL generates a random password and writes it to STDOUT. This means puppet can never access the database server afterwards, as no credentials are available.

This type is an internal type and should not be called directly.

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.

Tasks

The MySQL module has an example task that allows a user to execute arbitary SQL against a database. Please refer to to the PE documentation or Bolt documentation on how to execute a task.

Limitations

This module has been tested on:

RedHat Enterprise Linux 5, 6, 7
Debian 6, 7, 8
CentOS 5, 6, 7
Ubuntu 10.04, 12.04, 14.04, 16.04
Scientific Linux 5, 6
SLES 11

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

Note: The mysqlbackup.sh does not work and is not supported on MySQL 5.7 and greater.

Debian 9 compatibility has not been fully verified.

Development

Puppet 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.
