This cookbooks installs Redis 2 key-value datastore server. Redis can be installed from packages (where available) or source.
For compiling from source: build-essential
package to install from distro packages, any other value to install from source.
default attributes for all redis instances, will be merged with per instance attributes
per instance configuration attributes tree
This cookbook implements redis instances as a definition. If you plan to run only one instance, use the redis::default_instance recipe which call a “redis_default” redis_instance. 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, data_dir and master are the only attributes directly configurable using the definition syntax. Other attributes can be configured using the normal attribute interface under the node["redis2"]["instances"][instance_name] scope. Missing attributes will be merged from node["redis2"]["instances"]["default"]
The master attribute will set up redis as a slave of a the same redis instance on another server. It will not set node["redis2"]["instances"][instance_name]["replication"]["role"] (which can be slave or master), because redis can be both at the same time (e.g. chained masters).
redis2::auto - automagically call redis_instance for every instance defined in the node["redis2"]["instances"] 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.
