#Redis Module for Puppet
[![puppet-redis](https://img.shields.io/puppetforge/v/fsalum/redis.svg)](https://forge.puppetlabs.com/fsalum/redis) [![Build Status](https://travis-ci.org/fsalum/puppet-redis.svg?branch=master)](https://travis-ci.org/fsalum/puppet-redis)
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](https://github.com/fsalum/puppet-redis/blob/master/manifests/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](http://redis.io/topics/admin) - 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](https://github.com/fsalum/puppet-redis/blob/master/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',
}
}
}

# sentinel monitor <master-name> <ip> <redis-port> <quorum>
#
# Tells Sentinel to monitor this master, and to consider it in O_DOWN
# (Objectively Down) state only if at least <quorum> sentinels agree.
#
# Note that whatever is the ODOWN quorum, a Sentinel will require to
# be elected by the majority of the known Sentinels in order to
# start a failover, so no failover can be performed in minority.
#
# Slaves are auto-discovered, so you don't need to specify slaves in
# any way. Sentinel itself will rewrite this configuration file adding
# the slaves using additional configuration options.
# Also note that the configuration file is rewritten when a
# slave is promoted to master.
#
# Note: master name should not include special characters or spaces.
# The valid charset is A-z 0-9 and the three characters ".-_".
#sentinel monitor mymaster 127.0.0.1 6379 2
# sentinel auth-pass <master-name> <password>
#
# Set the password to use to authenticate with the master and slaves.
# Useful if there is a password set in the Redis instances to monitor.
#
# Note that the master password is also used for slaves, so it is not
# possible to set a different password in masters and slaves instances
# if you want to be able to monitor these instances with Sentinel.
#
# However you can have Redis instances without the authentication enabled
# mixed with Redis instances requiring the authentication (as long as the
# password set is the same for all the instances requiring the password) as
# the AUTH command will have no effect in Redis instances with authentication
# switched off.
#
# Example:
#
# sentinel auth-pass mymaster MySUPER--secret-0123passw0rd
# sentinel down-after-milliseconds <master-name> <milliseconds>
#
# Number of milliseconds the master (or any attached slave or sentinel) should
# be unreachable (as in, not acceptable reply to PING, continuously, for the
# specified period) in order to consider it in S_DOWN state (Subjectively
# Down).
#
# Default is 30 seconds.
#sentinel down-after-milliseconds mymaster 30000
# sentinel parallel-syncs <master-name> <numslaves>
#
# How many slaves we can reconfigure to point to the new slave simultaneously
# during the failover. Use a low number if you use the slaves to serve query
# to avoid that all the slaves will be unreachable at about the same
# time while performing the synchronization with the master.
#sentinel parallel-syncs mymaster 1
# sentinel failover-timeout <master-name> <milliseconds>
#
# Specifies the failover timeout in milliseconds. It is used in many ways:
#
# - The time needed to re-start a failover after a previous failover was
# already tried against the same master by a given Sentinel, is two
# times the failover timeout.
#
# - The time needed for a slave replicating to a wrong master according
# to a Sentinel current configuration, to be forced to replicate
# with the right master, is exactly the failover timeout (counting since
# the moment a Sentinel detected the misconfiguration).
#
# - The time needed to cancel a failover that is already in progress but
# did not produced any configuration change (SLAVEOF NO ONE yet not
# acknowledged by the promoted slave).
#
# - The maximum time a failover in progress waits for all the slaves to be
# reconfigured as slaves of the new master. However even after this time
# the slaves will be reconfigured by the Sentinels anyway, but not with
# the exact parallel-syncs progression as specified.
#
# Default is 3 minutes.
#sentinel failover-timeout mymaster 180000
# SCRIPTS EXECUTION
#
# sentinel notification-script and sentinel reconfig-script are used in order
# to configure scripts that are called to notify the system administrator
# or to reconfigure clients after a failover. The scripts are executed
# with the following rules for error handling:
#
# If script exits with "1" the execution is retried later (up to a maximum
# number of times currently set to 10).
#
# If script exits with "2" (or an higher value) the script execution is
# not retried.
#
# If script terminates because it receives a signal the behavior is the same
# as exit code 1.
#
# A script has a maximum running time of 60 seconds. After this limit is
# reached the script is terminated with a SIGKILL and the execution retried.
# NOTIFICATION SCRIPT
#
# sentinel notification-script <master-name> <script-path>
#
# Call the specified notification script for any sentinel event that is
# generated in the WARNING level (for instance -sdown, -odown, and so forth).
# This script should notify the system administrator via email, SMS, or any
# other messaging system, that there is something wrong with the monitored
# Redis systems.
#
# The script is called with just two arguments: the first is the event type
# and the second the event description.
#
# The script must exist and be executable in order for sentinel to start if
# this option is provided.
#
# Example:
#
# sentinel notification-script mymaster /var/redis/notify.sh
# CLIENTS RECONFIGURATION SCRIPT
#
# sentinel client-reconfig-script <master-name> <script-path>
#
# When the master changed because of a failover a script can be called in
# order to perform application-specific tasks to notify the clients that the
# configuration has changed and the master is at a different address.
#
# The following arguments are passed to the script:
#
# <master-name> <role> <state> <from-ip> <from-port> <to-ip> <to-port>
#
# <state> is currently always "failover"
# <role> is either "leader" or "observer"
#
# The arguments from-ip, from-port, to-ip, to-port are used to communicate
# the old address of the master and the new address of the elected slave
# (now a master).
#
# This script should be resistant to multiple invocations.
#
# Example:
#
# sentinel client-reconfig-script mymaster /var/redis/reconfig.sh
