The proxysql module installs, configures and manages the ProxySQL service.

This module will install the ProxySQL and manage it's configuration. It also extends Puppet to be able to manage mysql_users, mysql_servers, mysql_replication_hostgroups, mysql_query_rules, scheduler and global_variables.

Setup

Setup Requirements OPTIONAL

The module requires Puppet 4.x and currently supports only Debian 8 "Jessie" (and possibly Debian 7 "Wheezy").

Note: the ProxySQL-package is currently not in any public upstream package manager. So you should consider uploading it to a private package manager and manage that before calling the proxysql-class.

Beginning with proxysql

To install the ProxySQL software with all the default options:

include ::proxysql

You can customize options such as (but not limited to) listen_port, admin_password, monitor_password, ...

  class { '::proxysql':
    listen_port              => 3306,
    admin_password           => '654321',
    monitor_password         => '123456',
    override_config_settings => $override_settings,
    repo                     => {
      'debs_proxysql_repo' => {
        comment  => 'ProxySQL repo',
        location => 'http://debs.example.tld/debian',
        repos    => 'proxsql',
      },
    },
  }

Usage

Configuration is done by the proxysql class.

Customize config settings

You can override any configuration setting by using the override_config_settings hash. This hash resembles the structure of the proxysql.cnf file

{
    admin_variables => {
      refresh_interval => 2000,
      ...
    },
    mysql_variables => {
      monitor_writer_is_also_reader => false,
      ...
    },
    mysql_servers => {
      'mysql1' => {
         'address' => '127.0.0.1',
         'port'    => 33061,
       },
      'mysql2' => {
         'address' => '127.0.0.1',
         'port'    => 33062,
       },
      ...
    },
    mysql_users => { ... },
    mysql_query_rules => { ... },
    scheduler => { ... },
    mysql_replication_hostgroups => { ... },

}
