Description

Installs haproxy and prepares the configuration location.

Requirements

Platform

  • Ubuntu (10.04+ due to config option change)
  • Debian (6.0+)

Attributes

  • node['haproxy']['incoming_port'] - sets the port on which haproxy listens
  • node['haproxy']['member_port'] - the port that member systems will be listening on, default 80
  • node['haproxy']['enable_admin'] - whether to enable the admin interface. default true. Listens on port 22002.
  • node['haproxy']['app_server_role'] - used by the app_lb recipe to search for a specific role of member systems. Default webserver.
  • node['haproxy']['balance_algorithm'] - sets the load balancing algorithm; defaults to roundrobin.
  • node['haproxy']['member_max_connections'] - the maxconn value to be set for each app server
  • node['haproxy']['x_forwarded_for'] - if true, creates an X-Forwarded-For header containing the original client's IP address. This option disables KeepAlive.
  • node['haproxy']['enable_ssl'] - whether or not to create listeners for ssl, default false
  • node['haproxy']['ssl_member_port'] - the port that member systems will be listening on for ssl, default 8443
  • node['haproxy']['ssl_incoming_port'] - sets the port on which haproxy listens for ssl, default 443

Usage

Use either the default recipe or the app_lb recipe.

When using the default recipe, modify the haproxy.cfg.erb file with listener(s) for your sites/servers.

The app_lb recipe is designed to be used with the application cookbook, and provides search mechanism to find the appropriate application servers. Set this in a role that includes the haproxy::app_lb recipe. For example,

name "load_balancer"
description "haproxy load balancer"
run_list("recipe[haproxy::app_lb]")
override_attributes(
  "haproxy" => {
    "app_server_role" => "webserver"
  }
)

The search uses the node's chef_environment. For example, create environments/production.rb, then upload it to the server with knife

% cat environments/production.rb
name "production"
description "Nodes in the production environment."
% knife environment from file production.rb
