#Redis Module for Puppet

This module installs and manages a Redis server. All redis.conf options are accepted in the parameterized class.

##Important

If you are upgrading this module from 0.x to 1.0+, please test it carefully outside production as it is not fully backwards compatible.

Some class parameters were added, removed or had their default values changed.

The redis.conf template has been completely rewritten to support Redis 2.2+ to 2.8+.

##Operating System

Tested on CentOS 6.5, Ubuntu Saucy/Trusty/Precise, Debian 7.4
redis.conf options compatible with Redis 2.2, 2.4, 2.6, 2.8

##Quick Start

Use the default parameters:

class { 'redis': }

To change the port and listening network interface:

class { 'redis':
  conf_port => '6379',
  conf_bind => '0.0.0.0',
}

##Parameters

Check the init.pp file for a complete list of parameters accepted.

• custom sysctl

To enable and set important Linux kernel sysctl parameters as described in the Redis Admin Guide - use the following configuration option:

class { 'redis':
  system_sysctl => true
}

By default, this sysctl parameter will not be enabled. Furthermore, you will need the sysctl module defined in the Modulefile file.

• service restart

If you need to execute a controlled restart of redis after changes due master/slave relationships to avoid that both are restarted at the same time use the parameter below.

class { 'redis':
  service_restart => false
}

By default service restart is true.

#Sentinel

This module supports Redis Sentinel that comes with Redis 2.8+ with all the configuration parameters.

It manages upstart scripts (can be deactivated with parameter manage_upstart_scripts = false).

##Operating System

Tested on Ubuntu 14.04 with Redis 2.8

##Quick Start

Example:

class { redis::sentinel:
  conf_port      => '26379',
  sentinel_confs => {
    'mymaster' => {
      'monitor'                 => '127.0.0.1 6379 2',
      'down-after-milliseconds' => '60000',
      'failover-timeout'        => 180000,
      'notification-script'     => '/etc/redis/scripts/thescript.py',
      'parallel-syncs'          => '3',
    },
    'resque' => {
      'monitor'                 => '127.0.0.1 6379 4',
      'down-after-milliseconds' => '10000',
      'failover-timeout'        => 180000,
      'notification-script'     => '/etc/redis/scripts/thescript.py',
      'parallel-syncs'          => '5',
    }
  }
}
