= DESCRIPTION:
This cookbooks installs Redis 2 key-value datastore server. Redis can be installed from packages (where available) or source.
= REQUIREMENTS:
For compiling from source: build-essential
= ATTRIBUTES:
[redis2.install_from] _package_ to install from distro packages, any other value to install from source.
[redis2.instances.default] default attributes for all redis instances, will be merged with per instance attributes
[redis2.instances._instance_name_] per instance configuration attributes tree
= USAGE:
This cookbook implements redis instances as a definition. If you plan to run only one instance, use the <tt>redis::default_instance</tt> recipe which call a "redis_default" <tt>redis_instance</tt>.
To spawn instances of redis, use the +redis_instance+ definition, usage is pretty straight forward:
redis_instance "datastore" do
port 8866
data_dir "/mnt/redis/datastore"
master master_node
end
_port_, <em>data_dir</em> and _master_ are the only attributes directly configurable using the definition syntax. Other attributes can be configured using the normal attribute interface under the <tt>node["redis2"]["instances"][instance_name]</tt> scope. Missing attributes will be merged from <tt>node["redis2"]["instances"]["default"]</tt>
The _master_ attribute will set up redis as a slave of a the same redis instance on another server. It will not set <tt>node["redis2"]["instances"][instance_name]["replication"]["role"]</tt> (which can be _slave_ or _master_), because redis can be both at the same time (e.g. chained masters).
== Recipes
* redis2::auto - automagically call redis_instance for every instance defined in the <tt>node["redis2"]["instances"]</tt> tree.
* redis2::default_instance - use this if you want a simple recipe with a single redis instance
It's generally not a good idea to use the redis2::default_instance recipe. If you want a single redis instance, either use redis_instance definition or redis2::auto and define your instance in the attributes tree.
