Description

Installs heartbeat, and includes resources/providers for managing
heartbeat configuration.

It is outside the scope of this cookbook and the README to replace
documentation and user understanding of the linux-ha and heartbeat
project.

• http://linux-ha.org/wiki/Heartbeat

Requirements

Requires a Chef Server due to use of Search.

Platform:

Supported via Platform Family:

• Debian
• RHEL

Attributes

• node['heartbeat']['conf_dir'] - Directory where heartbeat configuration lives.

The following attributes are used in recipe[heartbeat::config] to
pass into the LWRP used there. Each corresponds to a resource
attribute in the LWRP, making the recipe drivable with attributes,
e.g. set in a role. See the heartbeat resource attributes below for
descriptions.

• node['heartbeat']['config']['auto_failback']
• node['heartbeat']['config']['autojoin']
• node['heartbeat']['config']['compression']
• node['heartbeat']['config']['compression_threshold']
• node['heartbeat']['config']['deadtime']
• node['heartbeat']['config']['initdead']
• node['heartbeat']['config']['keepalive']
• node['heartbeat']['config']['logfacility']
• node['heartbeat']['config']['udpport']
• node['heartbeat']['config']['warntime']
• node['heartbeat']['config']['search']
• node['heartbeat']['config']['authkeys']
• node['heartbeat']['config']['active_key']
• node['heartbeat']['config']['mode']
• node['heartbeat']['config']['interface']
• node['heartbeat']['config']['mcast_group']
• node['heartbeat']['config']['mcast_ttl']
• node['heartbeat']['config']['resource_ip']

Resources/Providers

heartbeat

Manages heartbeat configuration files (ha.cf, authkeys, haresources).

Actions

• :create - Default Creates the configuration. This will search for a specified query (see the search resource attribute below), and fall back to finding the cookbook and recipe name where the LWRP is used in the node's recipes attribute.

Attributes

• auto_failback - used for the auto_failback configuration directive in ha.cf.
• autojoin - used for the autojoin configuration directive in ha.cf.
• compression - used for the compression configuration directive in ha.cf.
• compression_threshold - used for the compression_threshold configuration directive in ha.cf.
• deadtime - used for the deadtime configuration directive in ha.cf.
• initdead - used for the initdead configuration directive in ha.cf.
• keepalive - used for the keepalive configuration directive in ha.cf.
• logfacility - used for the logfacility configuration directive in ha.cf.
• udpport - used for the udpport configuration directive in ha.cf.
• warntime - used for the warntime configuration directive in ha.cf.
• search - a search query to use instead of the default (see description above).
• authkeys - sha1 keys used in the authkeys config file.
• active_key - the key used for the auth configuration directive in the authkeys config file.
• interface - used for the `` configuration directive in ha.cf.
• mcast_group - used for the `` configuration directive in ha.cf.
• mcast_ttl - used for the `` configuration directive in ha.cf.
• mode - tye network mode to use, can be ucast, bcast, or mcast, corresponds to the configuration directives in ha.cf.
• resource_groups - array of resource groups

Examples

See recipe[heartbeat::config].

heartbeat_ipaddr

Used in the heartbeat LWRP for the group IP.

heartbeat_resource_group

Manages the haresources resource_groups.

Recipes

default

Installs the heartbeat and heartbeat-dev packages, and manages the
heartbeat service. The recipe does not at this time manage any configuration.

config

Uses the heartbeat LWRP with the node['heartbeat']['config']
attributes to manage a complete heartbeat configuration.

Usage

Use the default recipe to install heartbeat's packages and manage
the service.

Use the LWRP in your own recipe, or set the attributes described above
and use the config recipe to setup a heartbeat-monitored application.
