Description

Installs and configures PostgreSQL as a client or a server.

Requirements

Platforms

• Debian, Ubuntu
• Red Hat/CentOS/Scientific (6.0+ required) - "EL6-family"
• Fedora
• SUSE

Tested on:

• Ubuntu 10.04, 11.10
• Red Hat 6.1, Scientific 6.1

Cookboooks

Requires Opscode's openssl cookbook for secure password generation.

Requires a C compiler and development headers in order to build the pg RubyGem to provide Ruby bindings so they're available in other cookbooks.

Opscode's build-essential cookbook provides this functionality on Debian, Ubuntu, and EL6-family.

While not required, Opscode's database cookbook contains resources and providers that can interact with a PostgreSQL database. This cookbook is a dependency of that one.

Attributes

The following attributes are set based on the platform, see the attributes/default.rb file for default values.

• node['postgresql']['version'] - version of postgresql to manage
• node['postgresql']['dir'] - home directory of where postgresql data and configuration lives.

The following attributes are generated in recipe[postgresql::server].

• node['postgresql']['password']['postgres'] - randomly generated password by the openssl cookbook's library.
• node['postgresql']['ssl'] - whether to enable SSL (off for version 8.3, true for 8.4).

Recipes

default

Includes the client recipe.

client

Installs postgresql client packages and development headers during the compile phase. Also installs the pg Ruby gem during the compile phase so it can be made available for the database cookbook's resources, providers and libraries.

server

Includes the server_debian or server_redhat recipe to get the appropriate server packages installed and service managed. Also manages the configuration for the server:

• generates a strong default password (via openssl) for postgres
• sets the password for postgres
• manages the pg_hba.conf file.

server_debian

Installs the postgresql server packages, manages the postgresql service and the postgresql.conf file.

server_redhat

Manages the postgres user and group (with UID/GID 26, per RHEL package conventions), installs the postgresql server packages, initializes the database and manages the postgresql service, and manages the postgresql.conf file.

Resources/Providers

See the database for resources and providers that can be used for managing PostgreSQL users and databases.

Usage

On systems that need to connect to a PostgreSQL database, add to a run list recipe[postgresql] or recipe[postgresql::client].

This does install the pg RubyGem, which has native C extensions, so that the resources and providers can be used in the database cookbook, or elsewhere in the same Chef run. Use Opscode's build-essential cookbook to make sure the proper build tools are installed so the C extensions can be compiled.

On systems that should be PostgreSQL servers, use recipe[postgresql::server] on a run list. This recipe does set a password and expect to use it. It performs a node.save when Chef is not running in solo mode. If you're using chef-solo, you'll need to set the attribute node['postgresql']['password']['postgres'] in your node's json_attribs file or in a role.
