Resource/Provider

This cookbook includes LWRPs for managing:

• PEAR channels
• PEAR/PECL packages
• PHP-FPM instances

php_pear_channel

PEAR Channels are alternative sources for PEAR packages. This LWRP provides and easy way to manage these channels.

Actions

• discover: Initialize a channel from its server.
• add: Add a channel to the channel list, usually only used to add private channels. Public channels are usually added using the :discover action
• update: Update an existing channel
• remove: Remove a channel from the List

Parameters

• channel_name: name attribute. The name of the channel to discover
• channel_xml: the channel.xml file of the channel you are adding

Example

# discover the horde channel
php_pear_channel "pear.horde.org" do
  action :discover
end

# download xml then add the symfony channel
remote_file "#{Chef::Config['file_cache_path']}/symfony-channel.xml" do
  source "http://pear.symfony-project.com/channel.xml"
  mode 0644
end
php_pear_channel "symfony" do
  channel_xml "#{Chef::Config['file_cache_path']}/symfony-channel.xml"
  action :add
end

# update the main pear channel
php_pear_channel 'pear.php.net' do
  action :update
end

# update the main pecl channel
php_pear_channel 'pecl.php.net' do
  action :update
end

php_pear

PEAR is a framework and distribution system for reusable PHP components. PECL is a repository for PHP Extensions. PECL contains C extensions for compiling into PHP. As C programs, PECL extensions run more efficiently than PEAR packages. PEARs and PECLs use the same packaging and distribution system. As such this LWRP is clever enough to abstract away the small differences and can be used for managing either. This LWRP also creates the proper module .ini file for each PECL extension at the correct location for each supported platform.

Actions

• install: Install a pear package - if version is provided, install that specific version
• upgrade: Upgrade a pear package - if version is provided, upgrade to that specific version
• remove: Remove a pear package
• purge: Purge a pear package (this usually entails removing configuration files as well as the package itself). With pear packages this behaves the same as :remove

Parameters

• package_name: name attribute. The name of the pear package to install
• version: the version of the pear package to install/upgrade. If no version is given latest is assumed.
• preferred_state: PEAR by default installs stable packages only, this allows you to install pear packages in a devel, alpha or beta state
• directives: extra extension directives (settings) for a pecl. on most platforms these usually get rendered into the extension's .ini file
• options: Add additional options to the underlying pear package command

Example

# upgrade a pear
php_pear "XML_RPC" do
  action :upgrade
end


# install a specific version
php_pear "XML_RPC" do
  version "1.5.4"
  action :install
end


# install the mongodb pecl
php_pear "mongo" do
  action :install
end


# install apc pecl with directives
php_pear "apc" do
  action :install
  directives(:shm_size => 128, :enable_cli => 1)
end


# install the beta version of Horde_Url
# from the horde channel
hc = php_pear_channel "pear.horde.org" do
  action :discover
end
php_pear "Horde_Url" do
  preferred_state "beta"
  channel hc.channel_name
  action :install
end


# install the YAML pear from the symfony project
sc = php_pear_channel "pear.symfony-project.com" do
  action :discover
end
php_pear "YAML" do
  channel sc.channel_name
  action :install
end

php_fpm

PHP-FPM is a relatively new extension to PHP that actually embeds a FastCGI process manager right inside the PHP codebase. It runs independently of Apache or NGINX and supports both Apache's mod_fcgi and NGINX's fastcgi modules. You can easily create farms of PHP application servers using PHP-FPM as the middleware to your web frontend (i.e. NGINX and PHP-FPM work pretty well).

Actions

• add: Adds a PHP-FPM instance and restarts the service
• remove: Removes the PHP-FPM instance profile from the PHP-FPM pool and restarts the PHP-FPM service

Parameters

• name: name attribute. Defines the PHP-FPM's pool name and actual .conf filename
• user: System user the pool runs as.
• group: System group the pool runs as.
• socket: Set to true to enable communication via a UNIX socket instead of IP. Only useful if you run PHP-FPM on the same system with the web server or over a shared filesystem (i.e. NFS)
• socket_path: The UNIX socket filename
• socket_user: The UNIX socket file owner
• socket_group: The UNIX socket file group
• socket_perms: The UNIX socket file permissions. Set it to "0666" if running the web server under a different user for the web server to be able to write to it.
• ip_address: IF you are not using a UNIX socket, bind the FPM instance to a specific IP address. Use 0.0.0.0 to bind to all interfaces
• port: TCP port to bind to, to accept requests
• ip_whitelist: An array of IP addresses from which we can accept requests. Useful only for IP-based communication
• max_children: Maximum number of concurrent running pool children
• start_servers: Initial number of started pool servers
• min_spare_servers: Minimum number of idling servers. Must be equal to or larger than start_servers.
• max_spare_servers: Maximum number of idling servers
• max_requests: Maximum number of requests a pool child has received after being recycled. Useful for combating memory leaks that can't be fixed in any other way
• backlog: Maximum number of pending requests a pool can have waiting
• status_url: A URL to query the status of the pool
• ping_url: A URL to ping for health monitoring
• ping_response: The response expected from pinging healthy instance
• log_filename: A log filename for pool request logging
• log_format: The format in which the pool will be logging to the request log
• slow_filename: A file for recording long-taking requests
• slow_timeout: The slow request threshold
• valid_extensions: A number of extensions that are considered safe for processing
• terminate_timeout: A timeout after which the pool master process will terminate the child. Must be equal or large to the longest expected maximum execution time
• initial_directory: A directory to change to before start accepting request
• flag_overrides: A hash of PHP flags that will be overridden in the manner of Apache's php_flag and php_admin_flag
• value_overrides: A hash of PHP values that will be overridden in the manner of Apache's php_value and php_admin_value
• env_overrides: A hash of environment variables that will be overridden embedded in the pools environment variable set

Example

# Define a pool for PHPMyAdmin
php_fpm 'phpmyadmin' do
  action :add
  user 'phpmyadmin'
  group 'phpmyadmin'
  socket true
  socket_path '/tmp/phpmyadmin.sock'
  socket_perms "0666"
  start_servers 2
  min_spare_servers 2
  max_spare_servers 8
  max_children 8
  terminate_timeout (node['php']['ini_settings']['max_execution_time'].to_i + 20)
  value_overrides({
    :error_log => "#{node['php']['fpm_log_dir']}/phpmyadmin.log"
  })
end

Recipes

default

Include the default recipe in a run list, to get php.

dotdeb

Include the dotdeb recipe in a run list to install the PHP distributed by the DotDeb repository instead of the official Ubuntu/Debian one.

package

This recipe installs PHP from packages.

fpm

This recipe installs and configures the PHP FastCGI Process Manager but without any pools. To define an application pool please use the php_fpm LWRP.

module_*

This recipe installs various PHP modules via the appropriate package commands. module_common will install a common set of PHP modules needed for most web applications (such as Joomla or Wordpress).

Usage

Simply include the php recipe where ever you would like php installed. To install from source override the node['php']['install_method'] - with in a role:

name "php"
description "Install php from source"
override_attributes(
  "php" => {
    "install_method" => "source"
  }
)
run_list(
  "recipe[php]"
)
