Description

Installs nginx from package OR source code and sets up configuration
handling similar to Debian's Apache2 scripts.

Requirements

Cookbooks

The following cookbooks are direct dependencies because they're used
for common "default" functionality.

build-essential (for nginx::source)
ohai (for nginx::ohai_plugin)

The following cookbook is not a strict dependency because its use can
be controlled by an attribute, so it may not be a common "default."

runit (for nginx::source)

On RHEL family distros, the "yum" cookbook is required for "recipe[yum::epel]".

Platform

The following platforms are supported and tested under test kitchen:

Ubuntu 10.04, Ubuntu 12.04
CentOS 5.8, 6.3

Other Debian and RHEL family distributions are assumed to work.

Attributes

Node attributes for this cookbook are logically separated into
different files. Some attributes are set only via a specific recipe.

default.rb

Generally used attributes. Some have platform specific values. See
attributes/default.rb. "The Config" refers to "nginx.conf" the main
config file.

v0.101.0 - Attribute Change: node['nginx']['url'] is now
node['nginx']['source']['url'] as the URL was only used when
retrieving the source to build Nginx.

node['nginx']['dir'] - Location for Nginx configuration.
node['nginx']['log_dir'] - Location for Nginx logs.
node['nginx']['user'] - User that Nginx will run as.
node['nginx']['group] - Group for Nginx.
node['nginx']['binary'] - Path to the Nginx binary.
node['nginx']['init_style'] - How to run Nginx as a service when using nginx::source. Values can be "runit", "init" or "bluepill". When using runit or bluepill, those recipes will be included as well and are dependencies of this cookbook. Not used in the nginx recipe because the package manager's init script style for the platform is assumed.
node['nginx']['pid'] - Location of the PID file.
node['nginx']['keepalive'] - Whether to use keepalive_timeout, any value besides "on" will leave that option out of the config.
node['nginx']['keepalive_timeout'] - used for config value of keepalive_timeout.
node['nginx']['worker_processes'] - used for config value of worker_processes.
node['nginx']['worker_connections'] - used for config value of events { worker_connections }
node['nginx']['worker_rlimit_nofile'] - used for config value of worker_rlimit_nofile. Can replace any "ulimit -n" command. The value depend on your usage (cache or not) but must always be superior than worker_connections.
node['nginx']['multi_accept'] - used for config value of events { multi_accept }. Try to accept() as many connections as possible. Disable by default.
node['nginx']['event'] - used for config value of events { use }. Set the event-model. By default nginx looks for the most suitable method for your OS.
node['nginx']['server_names_hash_bucket_size'] - used for config value of server_names_hash_bucket_size.
node['nginx']['disable_access_log'] - set to true to disable the general access log, may be useful on high traffic sites.
node['nginx']['default_site_enabled'] - enable the default site
node['nginx']['install_method'] - Whether nginx is installed from packages or from source.
node['nginx']['types_hash_max_size'] - Used for the types_hash_max_size configuration directive.
node['nginx']['types_hash_bucket_size'] - Used for the types_hash_bucket_size configuration directive.

Attributes for configuring the gzip module

node['nginx']['gzip'] - Whether to use gzip, can be "on" or "off"
node['nginx']['gzip_http_version'] - used for config value of gzip_http_version.
node['nginx']['gzip_comp_level'] - used for config value of gzip_comp_level.
node['nginx']['gzip_proxied'] - used for config value of gzip_proxied.
node['nginx']['gzip_types'] - used for config value of gzip_types - must be an Array.

Attributes set in recipes

nginx::source

node['nginx']['daemon_disable'] - Whether the daemon should be disabled which can be true or false; disable the daemon (run in the foreground) when using a service supervisor such as runit or bluepill for "init_style". This is automatically set in the nginx::source recipe when the init style is not bluepill or runit.

nginx::authorized_ips

node['nginx']['remote_ip_var'] - The remote ip variable name to use.
node['nginx']['authorized_ips'] - IPs authorized by the module

nginx::http_realip_module

From: http://wiki.nginx.org/HttpRealIpModule

node['nginx']['realip']['header'] - Header to use for the RealIp Module; only accepts "X-Forwarded-For" or "X-Real-IP"
node['nginx']['realip']['addresses'] - Addresses to use for the http_realip configuration.

source.rb

These attributes are used in the nginx::source recipe. Some of them
are dynamically modified during the run. See attributes/source.rb
for default values.

node['nginx']['source']['url'] - (versioned) URL for the Nginx source code. By default this will use the version specified as `node['nginx']['version'].
node['nginx']['source']['prefix'] - (versioned) prefix for installing nginx from source
node['nginx']['source']['conf_path'] - location of the main config file, in node['nginx']['dir'] by default.
node['nginx']['source']['modules'] - Array of modules that should be compiled into Nginx by including their recipes in nginx::source.
node['nginx']['source']['default_configure_flags'] - The default flags passed to the configure script when building Nginx.
node['nginx']['configure_flags'] - Preserved for compatibility and dynamically generated from the node['nginx']['source']['default_configure_flags'] in the nginx::source recipe.

geoip.rb

These attributes are used in the nginx::http_geoip_module recipe.
Please note that the country_dat_checksum and city_dat_checksum
are based on downloads from a datacenter in Fremont, CA, USA. You
really should override these with checksums for the geo tarballs from
your node location.

Note The upstream, maxmind.com, may block access for repeated
downloads of the data files. It is recommended that you download and
host the data files, and change the URLs in the attributes.

node['nginx']['geoip']['path'] - Location where to install the geoip libraries.
node['nginx']['geoip']['enable_city'] - Whether to enable City data
node['nginx']['geoip']['country_dat_url'] - Country data tarball URL

node['nginx']['geoip']['lib_url'] - (Versioned) Tarball URL of the GeoIP library
node['nginx']['geoip']['lib_checksum'] - Checksum of the GeoIP library tarball

upload_progress.rb

These attributes are used in the nginx::upload_progress_module
recipe.

node['nginx']['upload_progress]['url'] - URL for the tarball.
node['nginx']['upload_progress']['checksum'] - Checksum of the tarball.

passenger.rb

Recipes

This cookbook provides two main recipes for installing Nginx.

default.rb: Use this recipe if you have a native package for Nginx.
source.rb: Use this recipe if you do not have a native package for Nginx, or if you want to install a newer version than is available, or if you have custom module compilation needs.

Several recipes are related to the source recipe specifically. See
that recipe's section below for a description.

default.rb

The default recipe will install Nginx as a native package for the
system through the package manager and sets up the configuration
according to the Debian site enable/disable style with sites-enabled
using the nxensite and nxdissite scripts. The nginx service will
be managed with the normal init scripts that are presumably included
in the native package.

Includes the ohai_plugin recipe so the plugin is available.

ohai_plugin.rb

This recipe provides an Ohai plugin as a template. It is included by
both the default and source recipes.

authorized_ips.rb

Sets up configuration for the authorized_ip nginx module.

source.rb

This recipe is responsible for building Nginx from source. It ensures
that the required packages to build Nginx are installed (pcre,
openssl, compile tools). The source will be downloaded from the
node['nginx']['source']['url']. The node['nginx']['user'] will be
created as a system user. The appropriate configuration and log
directories and config files will be created as well according to the
attributes node['nginx']['dir'] and 'node['nginx']['log_dir']`.

The recipe attempts to detect whether additional modules should be
added to the configure command through recipe inclusion (see below),
and whether the version or configuration flags have changed and should
trigger a recompile.

The nginx service will be set up according to
node['nginx']['init_style']. Available options are:

runit: uses runit cookbook and sets up runit_service.
bluepill: uses bluepill cookbook and sets up bluepill_service.
anything else (e.g., "init") will use the nginx init script template.

RHEL/CentOS This recipe should work on RHEL/CentOS with "init" as
the init style.

The following recipes are used to build module support into Nginx. To
use a module in the nginx::source recipe, add its recipe name to the
attribute node['nginx']['source']['modules'].

http_echo_module.rb - downloads the http_echo_module module and enables it as a module when compiling nginx.
http_geoip_module.rb - installs the GeoIP libraries and data files and enables the module for compilation.
http_gzip_static_module.rb - enables the module for compilation.
http_realip_module.rb - enables the module for compilation and creates the configuration.
http_ssl_module.rb - enables SSL for compilation.
http_stub_status_module.rb - provides nginx_status configuration and enables the module for compilation.
naxsi_module - enables the naxsi module for the web application firewall for nginx.
passenger - builds the passenger gem and configuration for "mod_passenger".
upload_progress_module.rb - builds the upload_progress module and enables it as a module when compiling nginx.

Adding New Modules

To add a new module to be compiled into nginx in the source recipe,
the node's run state is manipulated in a recipe, and the module as a
recipe should be added to node['nginx']['source']['modules']. For
example:

node.run_state['nginx_configure_flags'] =
  node.run_state['nginx_configure_flags'] | ["--with-http_stub_status_module"]

The recipe will be included by recipe[nginx::source] automatically,
adding the configure flags. Add any other configuration templates or
other resources as required. See the recipes described above for
examples.

Ohai Plugin

The ohai_plugin recipe includes an Ohai plugin. It will be
automatically installed and activated, providing the following
attributes via ohai, no matter how nginx is installed (source or
package):

node['nginx']['version'] - version of nginx
node['nginx']['configure_arguments'] - options passed to ./configure when nginx was built
node['nginx']['prefix'] - installation prefix
node['nginx']['conf_path'] - configuration file path

In the source recipe, it is used to determine whether control
attributes for building nginx have changed.

Usage

Include the recipe on your node or role that fits how you wish to
install Nginx on your system per the recipes section above. Modify the
attributes as required in your role to change how various
configuration is applied per the attributes section above. In general,
override attributes in the role should be used when changing
attributes.

There's some redundancy in that the config handling hasn't been
separated from the installation method (yet), so use only one of the
recipes, default or source.
