DESCRIPTION:

Installs and configures Redis.

** NOTE ** This cookbook does not currently configure or manage Redis replication.

REQUIREMENTS:

The Redis cookbook has been tested on Ubuntu 10.04, 11.04, 11.10, and CentOS 5 and 6.

Cookbooks:

  • build-essential - Used when compiling Redis.
  • runit - Used only if Redis is configured to start with Runit.

ATTRIBUTES:

Installation:

  • ['redis']['install_type'] - Install the Package by default. [ package, source ]
  • ['redis']['source']['sha'] - The sha256 checksum of the source tarball.
  • ['redis']['source']['url'] - The url to the source tarball.
  • ['redis']['source']['version'] - The version of Redis to install.
  • ['redis']['src_dir'] - Extract the Redis source to this directory.
  • ['redis']['dst_dir'] - Install compiled Redis to this directory.
  • ['redis']['conf_dir'] - The Redis configuration directory.
  • ['redis']['init_style'] - A value of "init" is currently recommended, but full runit support is coming soon.

Configuration:

The config file template should support all current configuration options. If we've missed something please file a ticket.

  • ['redis']['config']['appendonly'] - Use the AOF file writing system.
  • ['redis']['config']['appendfsync'] - The mode Redis uses for fsync() calls. [ everysec, no, always ]
  • ['redis']['config']['daemonize'] - Run Redis as a daemon. In this mode Redis will create a pid file.
  • ['redis']['config']['databases'] - Set the number of Redis databases.
  • ['redis']['config']['dbfilename'] - The filename where the database is dumped.
  • ['redis']['config']['dir'] - The directory where Redis will store its DB and AOF files.
  • ['redis']['config']['listen_addr'] - Address to listen on. Defaults to localhost.
  • ['redis']['config']['listen_port'] - Port to listen on.
  • ['redis']['config']['logfile'] - The Redis logfile.
  • ['redis']['config']['loglevel'] - Changes logging verbosity. [debug, verbose, notice, warning ]
  • ['redis']['config']['pidfile'] - When daemonize is enabled this configures where Redis will write the pid file.
  • ['redis']['config']['rdbcompression'] - Whether or not to use LZF compression when dumping .rdb databases. [ yes, no ]
  • ['redis']['config']['timeout'] - Configures when Redis will timeout a idle client connection.
  • ['redis']['config']['vm']['enabled']- Use Redis' virtual memory.
  • ['redis']['config']['vm']['max_memory'] - Limits the amount of memory available to Redis.
  • ['redis']['config']['vm']['max_threads'] - Maximum number of VM I/O threads running simultaneously.
  • ['redis']['config']['vm']['page_size'] - Configures the page size Redis uses when writing out swap files.
  • ['redis']['config']['vm']['pages'] - The total number of memory pages in a swap file.
  • ['redis']['config']['vm']['vm_swap_file'] - The Redis swapfile.

** The following configuration settings are only available in redis >= 2.1.12 -- http://redis.io/commands/slowlog **

  • ['redis']['config']['configure_slowlog'] - Adds or Removes slowlog options from your redis.conf [ true, nil ]
  • ['redis']['config']['slowlog_log_slower_than'] - Time in microseconds a command must run beyond to be caught by the slow logger.
  • ['redis']['config']['slowlog_max_len'] - The length of the slow log.

USAGE:

There are several recipes broken up into reusable pieces. For ease of use, we've also included wrappers that map the most common use.

  • redis::_group - Creates a group for Redis.
  • redis::_server_config - Creates configuration directories and installs templatized redis.conf.
  • redis::_server_init - Installs a templatized Redis sysv initscript.
  • redis::_server_install_from_package - Installs Redis through the chef package resource.
  • redis::_server_install_from_package - Downloads, compiles, and installs Redis from source.
  • redis::_server_runit - Installs templatized Redis runit configuration.
  • redis::_server_service - Configures Redis through the chef service resource.
  • redis::_user - Creates a user for Redis.
  • redis::default - The default recipe executes the redis::server_package recipe.
  • redis::server - The default recipe executes the redis::server_package recipe. This recipe is here for compatibility with other community Redis cookbooks.
  • redis::server_package - Uses the recipe crumbs in the Redis cookbook to manage a packaged Redis instance.
  • redis::server_source - Uses the recipe crumbs in the Redis cookbook to manage a source compiled Redis instance.
