Description

Installs Redis, an advanced key-value store whose keys can be strings, hashes, lists, sets and sorted sets.

Requirements

Platforms

• CentOS 5.x, 6.x
• Red Hat Enterprise Linux 5.x, 6.x
• Ubuntu 12.04.1 (Precise)

Tested with Redis 2.4.x on CentOS/Red Hat Enterpise, and Redis 2.2.x on Ubuntu.

Cookbooks

• yum

Redis lives within the EPEL repository, so you'll need to include yum::epel in your run list. (It seems to be a matter of debate whether or not cookbook authors should include_recipe this -- I haven't, at least for now.)

Attributes

Global options

• ['redis']['server']['bind_address'] - what address to bind to (default 127.0.0.1; set to 0.0.0.0 if you're connecting to Redis from another server)
• ['redis']['server']['idle_timeout'] - idle timeout
• ['redis']['server']['log_level'] - what log level should the Redis server log at
• ['redis']['server']['datadir'] - where RDB or AOF format snapshots/data files will live

RDB format snapshots

• ['redis']['server']['snapshotting'] - whether to generate RDB format snapshots; false by default
• ['redis']['server']['snapshot_compression'] - whether to compress RDB format snapshots; true by default
• ['redis']['server']['snapshot_file'] - name of the snapshot file, 'dump.rdb' by default
• ['redis']['server']['snapshot_intervals'] - an array of snapshot policies, each element of which is a policy. Will save the DB if both the given number of seconds (the first element) and the given number of write operations (the second element) against the DB occurred.

Master-Slave

Note that the slave finds the master using Search, so this doesn't work in Chef Solo.

• ['redis']['server']['is_slave'] - whether to operate this instance as a slave.
• ['redis']['server']['master_role'] - name of the role to search for, to find the master.

AOF (Append-Only File) Format Snapshots

• ['redis']['server']['appendonly'] - whether to generate AOF-format snapshots; default is false.
• ['redis']['server']['aof_file'] - name of the AOF file, 'appendonly.aof' by default
• ['redis']['server']['fsync_style'] - when to fsync() the file; 'everysec' by default

Recipes

default

Does nothing.

server

Installs Redis from EPEL packages and optionally configures it as a slave if you have set the ['redis']['server']['is_slave'] attribute.

Limitations

• Not every parameter is configurable in redis.conf.
• Slave search logic assumes that you're using Chef environments and that the master resides in the same environment.
