nginx Cookbook

Cookbook Build Status

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 source installations
  • ohai for setting up the ohai plugin
  • compat_resource for setting up the nginx.org repository on Chef 12.1 - 12.13
  • yum-epel for setting up the EPEL repository on RHEL platforms
  • zypper for setting up the nginx.org repository on Suse platforms

Platforms

The following platforms are supported and tested with Test Kitchen:

  • Ubuntu 14.04+
  • CentOS 6+
  • Debian 7+
  • openSUSE
  • FreeBSD

Other Debian and RHEL family distributions are assumed to work.

Chef

  • Chef 12.1+

Attributes

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

nginx::auth_request

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

  • node['nginx']['auth_request']['url'] - The url to the auth_request module tar.gz file
  • node['nginx']['auth_request']['checksum'] - The checksum of the auth_request module tar.gz file

nginx::default

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

  • node['nginx']['upstart']['runlevels'] - String of runlevels in the format '2345' which determines which runlevels nginx will start at when entering and stop at when leaving.
  • node['nginx']['upstart']['respawn_limit'] - Respawn limit in upstart stanza format, count followed by space followed by interval in seconds.

Resources

nginx_site

Enable or disable a Server Block in #{node['nginx']['dir']}/sites-available by calling nxensite or nxdissite (introduced by this cookbook) to manage the symbolic link in #{node['nginx']['dir']}/sites-enabled.

Actions

  • enable - Enable the nginx site (default)
  • disable - Disable the nginx site

Properties:

  • name - (optional) Name of the site to enable. By default it's assumed that the name of the nginx_site resource is the site name, but this allows overriding that.
  • template - (optional) Path to the source for the template resource.
  • variables - (optional) Variables to be used with the template resource

nginx_cleanup_runit

A simple resource to remove existing runit based nginx service installations. This is used in the default nginx recipe to stop runit based nginx services and cleanup runit service configs before setting up nginx under the system's own init system.

Actions

  • cleanup - Stop runit based nginx and remove runit configs (default)

Usage

This cookbook provides three distinct installation methods, all of which are controlled via attributes and executed using the nginx::default recipe.

Package installation using the nginx.org repositories

Nginx provides repositories for RHEL, Debian/Ubuntu, and Suse platforms with up to date packages available on older distributions. Due to the age of many nginx packages shipping with distros we believe this is the ideal installation method. With no attributes set the nginx.org repositories will be added to your system and nginx will be installed via package. This provides a solid out of the box install for most users.

Package installation using distro repositories

If you prefer to use the packages included in your distro or to roll your own packages you'll want to set node['nginx']['repo_source'] to nil or distro to skip the repository setup. The default recipe will still install nginx from packages, but you'll retain control over the package location.

Source installation to compile non-dynamic modules

If you need control over how nginx is built, or you need non-dynamic modules to be included you'll need to compile nginx from source. We highly recommend against using this method as it requires the installation of a full compilation toolchain and development dependencies on your nodes. Creating your own packages with nginx compiled as necessary is a preferred option. If that's not possible you can set node['nginx']['install_method'] to source and provide a version in node['nginx']['version'].

Specifying Modules to compile

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

  • ipv6.rb - enables IPv6 support
  • headers_more_module -
  • `http_auth_request_module``
  • 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. Be sure to set node['nginx']['gzip_static'] = 'yes'.
  • http_mp4_module -
  • http_perl_module.rb - enables embedded Perl for compilation.
  • http_realip_module.rb - enables the module for compilation and creates the configuration.
  • http_spdy_module -
  • http_ssl_module.rb - enables SSL for compilation.
  • http_stub_status_module.rb - provides nginx_status configuration and enables the module for compilation.
  • http_v2_module
  • ipv6 -
  • naxsi_module - enables the naxsi module for the web application firewall for nginx.
  • ngx_devel_module -
  • ngx_lua_module -
  • openssl_source.rb - downloads and uses custom OpenSSL source when compiling nginx
  • pagespeed_module-
  • passenger - builds the passenger gem and configuration for "mod_passenger".
  • set_misc -
  • syslog_module - enables syslog support for nginx. This only works with source builds. See https://github.com/yaoweibin/nginx_syslog_patch -
  • upload_progress_module.rb - builds the upload_progress module and enables it as a module when compiling nginx.

Resources

nginx_site

Enable or disable a Server Block in #{node['nginx']['dir']}/sites-available by calling nxensite or nxdissite (introduced by this cookbook) to manage the symbolic link in #{node['nginx']['dir']}/sites-enabled.

Actions

  • enable - Enable the nginx site (default)
  • disable - Disable the nginx site

Properties:

  • name - (optional) Name of the site to enable. By default it's assumed that the name of the nginx_site resource is the site name, but this allows overriding that.
  • template - (optional) Path to the source for the template resource.
  • cookbook - (optional) The cookbook that contains the template source.
  • variables - (optional) Variables to be used with the template resource

Adding New Modules

Previously we'd add each possible module to this cookbook itself. That's not necessary using wrapper cookbooks and we'd prefer to not add any addition module recipes at this time. Instead in your nginx wrapper cookbook setup any necessary packages and then include the follow code to add the module to the list of modules to compile:

node.run_state['nginx_configure_flags'] =
  node.run_state['nginx_configure_flags'] | ['--with-SOMETHING', "--with-SOME_OPT='things'"]
