chef-redis

Description

This cookbook installs Redis from Chris Lea's ppa archive.

Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

Requirements

Supported Platforms

The following platforms are supported by this cookbook, meaning that the recipes run on these platforms without error:

• Ubuntu 12.04+
• Debian 6+

Cookbooks

• apt
• minitest-handler (suggested, not required)

Recipes

• redis - The default recipe. Setup apt with ppa details.
• redis::server - Install the Redis server.
• redis::client - Install the Redis client.

Usage

This cookbook installs the Redis components if not present, and pulls updates if they are installed on the system.

Basic Settings

• node["redis"]["ulimit"] - Sets the maximum number of file descriptors for the Redis process. If this is unset or empty, the limit is the system default. The default may not be high enough to handle a large number of concurrent connections. See Redis Clients Handling.
