daemonize yes
pidfile /var/run/redis_6379.pid

Redis sentinel

In your hieradata file

    redis_26389:
        sentinel: true
        conf:
          sentinel monitor: mymaster 127.0.0.1 6379 2

          sentinel parallel-syncs: mymaster 1
          sentinel failover-timeout: mymaster 180000

It will create /etc/redis/26389.conf see file. The default template configuration comes from sentinel.conf provided by the original package. Only these default values are uncommented/added/changed:

Advanced configuration

Parameters

  • redis::version: version of Redis (required)
  • redis::servers: hash of servers instances, default { redis_6379 => {} }
    • sentinel: boolean, redis sentinel, default false
    • default_template: boolean, use default redis template, default true
    • conf: hash of redis properties, default { daemonize => 'yes' }
  • redis::conf_dir: configuration directory, default /etc/redis
  • redis::data_dir: data directory, default /var/lib/redis
  • redis::sysctl: boolean, apply sysctl overcommit conf, default true
  • redis::tmp: tmp directory used by install, default /tmp

Available redis properties

All properties can be added. But due to the regex used, there are some restrictions:

Don't forget double-quotes "" for "yes" and "no" otherwise puppet will understand true or false.

Some properties only work with default_template = true:

  • rename-command
  • appendfsync

The key of some others must have two parts:

  • client-output-buffer-limit

    • client-output-buffer-limit normal: 64mb 0 0
    • client-output-buffer-limit slave: 128mb 64mb 60
    • client-output-buffer-limit pubsub: 64mb 8mb 60

  • save

    • save 900: 1
    • save 300: 10
    • save 60: 10000

  • sentinel

    • sentinel monitor: mymaster 127.0.0.1 6379 2
    • sentinel auth-pass: mymaster MySUPER--secret-0123passw0rd
    • sentinel down-after-milliseconds: mymaster 30000
    • sentinel parallel-syncs: mymaster 2
    • sentinel failover-timeout: mymaster 190000
    • sentinel notification-script: mymaster /var/redis/notify.sh
    • sentinel client-reconfig-script: mymaster /var/redis/reconfig.sh

No template

redis::version: 2.8.8
redis::servers:
    my_redis_1:
      default_template: false
      conf:
        port: 9999
        property_key: property_value
        ...

It will create /etc/redis/9999.conf with these default values:

port 9999
logfile /var/log/redis_9999.log
dir /var/lib/redis/9999
pidfile /var/run/redis_9999.pid
daemonize yes
property_key property_value
