Overview

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, proxysql_servers, scheduler and global_variables.

Setup

Setup Requirements OPTIONAL

The module requires Puppet 4.10.0 over above.

It depends on the puppetlabs/mysql module (>= 2.5.x) and on the puppetlabs/apt module (>= 2.1.x) when using deb based systems.

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           => Sensitive('654321'),
    monitor_password         => Sensitive('123456'),
    override_config_settings => $override_settings,
  }

You can configure users\hostgroups\rules\schedulers using class parameters

  class { 'proxysql':
     mysql_servers    => [ 
       { 
         'db1' => { 
           'port' => 3306, 
           'hostgroup_id' => 1, 
         } 
       },
       { 
         'db2' => { 
           'hostgroup_id' => 2, 
         } 
       },
     ],
     mysql_users      => [ 
       { 
         'app' => { 
           'password' => '*92C74DFBDA5D60ABD41EFD7EB0DAE389F4646ABB', 
           'default_hostgroup' => 1, 
         } 
       },
       { 
         'ro'  => { 
           'password' => mysql_password('MyReadOnlyUserPassword'), 
           'default_hostgroup' => 2, 
         } 
       },
     ],
     mysql_hostgroups => [ 
       { 
         '1-2' => { 
           'writer_hostgroup' => 1, 
           'reader_hostgroup' => 2, 
         } 
       },
     ],
     mysql_rules      => [ 
       { 
         'mysql_query_rule-1' => { 
           'rule_id'         => 1,
           'match_pattern'   => 'testtable',
           'replace_pattern' => 'test.newtable',
           'apply'           => 1,
           'active'          => 1, 
         }
       },
     ],
     schedulers       => [ 
       { 
         'scheduler-1' => { 
           'scheduler_id'  => 1,
           'active'        => 0,
           'filename'      => '/usr/bin/whoami', 
         }
       },
     ],

Or by using individual resources:

  class { 'proxysql':
    listen_port    => 3306,
    admin_password => Sensitive('SuperSecretPassword'),
  }

  proxy_mysql_server { '192.168.33.31:3306-31':
    hostname     => '192.168.33.31',
    port         => 3306,
    hostgroup_id => 31,
  }
  proxy_mysql_server { '192.168.33.32:3306-31':
    hostname     => '192.168.33.32',
    port         => 3306,
    hostgroup_id => 31,
  }
  proxy_mysql_server { '192.168.33.33:3306-31':
    hostname     => '192.168.33.33',

    port         => 3306,
    hostgroup_id => 31,
  }

  proxy_mysql_replication_hostgroup { '30-31':
    writer_hostgroup => 30,
    reader_hostgroup => 31,
    comment          => 'Replication Group 1',
  }
  proxy_mysql_replication_hostgroup { '20-21':
    writer_hostgroup => 20,
    reader_hostgroup => 21,
    comment          => 'Replication Group 2',
  }

  proxy_mysql_user { 'tester':
    password          => 'testerpwd',
    default_hostgroup => 30,
  }

  proxy_mysql_query_rule { 'mysql_query_rule-1':
    rule_id               => 1,
    match_pattern         => '^SELECT',
    apply                 => 1,
    active                => 1,
    destination_hostgroup => 31,
  }

  proxy_scheduler { 'scheduler-1':
    scheduler_id => 1,
    active       => 0,
    filename     => '/usr/bin/whoami',
  }

  proxy_scheduler { 'scheduler-2':
    scheduler_id => 2,
    active       => 0,
    interval_ms  => 1000,
    filename     => '/usr/bin/id',
  }

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 => {
      '127.0.0.1:33061-1' => {
         'address'      => '127.0.0.1',
         'port'         => 33061,
         'hostgroup_id' => 1,
       },
      '127.0.0.1:33062-1' => {
         'address'      => '127.0.0.1',
         'port'         => 33062,
         'hostgroup_id' => 1,
       },
      ...
    },
    mysql_users => { ... },
    mysql_query_rules => { ... },
    scheduler => { ... },
    mysql_replication_hostgroups => { ... },

}
