# Mysql module for Puppet

This module manages mysql on Linux (RedHat/Debian) distros. A native mysql provider implements database resource type to handle database, database user, and database permission.

Pluginsync needs to be enabled for this module to function properly.
Read more about pluginsync in our [docs](http://docs.puppetlabs.com/guides/plugins_in_modules.html#enabling-pluginsync)

## Description

This module uses the fact osfamily which is supported by Facter 1.6.1+. If you do not have facter 1.6.1 in your environment, the following manifests will provide the same functionality in site.pp (before declaring any node):

    if ! $::osfamily {
      case $::operatingsystem {
        'RedHat', 'Fedora', 'CentOS', 'Scientific', 'SLC', 'Ascendos', 'CloudLinux', 'PSBM', 'OracleLinux', 'OVS', 'OEL': {
          $osfamily = 'RedHat'
        }
        'ubuntu', 'debian': {
          $osfamily = 'Debian'
        }
        'SLES', 'SLED', 'OpenSuSE', 'SuSE': {
          $osfamily = 'Suse'
        }
        'Solaris', 'Nexenta': {
          $osfamily = 'Solaris'
        }
        default: {
          $osfamily = $::operatingsystem
        }
      }
    }

This module depends on creates_resources function which is introduced in Puppet 2.7. Users on puppet 2.6 can use the following module which provides this functionality:

## Usage

### mysql
Installs the mysql-client package.

    class { 'mysql': }

### mysql::java
Installs mysql bindings for java.

    class { 'mysql::java': }

### mysql::python
Installs mysql bindings for python.

    class { 'mysql::python': }

### mysql::ruby
Installs mysql bindings for ruby.

    class { 'mysql::ruby': }

### mysql::server
Installs mysql-server packages, configures my.cnf and starts mysqld service:

    class { 'mysql::server':
      config_hash => { 'root_password' => 'foo' }
    }

Database login information stored in `/root/.my.cnf`.

### mysql::db
Creates a database with a user and assign some privileges.

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

### mysql::backup
Installs a mysql backup script, cronjob, and priviledged backup user.

    class { 'mysql::backup':
      backupuser     => 'myuser',
      backuppassword => 'mypassword',
      backupdir      => '/tmp/backups',
    }

### Providers for database types:
MySQL provider supports puppet resources command:

    $ puppet resource database
    database { 'information_schema':
      ensure  => 'present',
      charset => 'utf8',
    }
    database { 'mysql':
      ensure  => 'present',
      charset => 'latin1',
    }

The custom resources can be used in any other manifests:

    database { 'mydb':
      charset => 'latin1',
    }

    database_user { 'bob@localhost':
      password_hash => mysql_password('foo')
    }

    database_grant { 'user@localhost/database':
      privileges => ['all'] ,
      # Or specify individual privileges with columns from the mysql.db table:
      # privileges => ['Select_priv', 'Insert_priv', 'Update_priv', 'Delete_priv']
    }

A resource default can be specified to handle dependency:

    Database {
      require => Class['mysql::server'],
    }
