Installs nginx from package OR source code and sets up configuration handling similar to Debian's Apache2 scripts.
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]
".
On Ubuntu, when using Nginx.org's stable package, "recipe[apt]
"
is required.
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.
Node attributes for this cookbook are logically separated into different files. Some attributes are set only via a specific recipe.
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']

retrieving the source to build Nginx.

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']

recipe.
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.

This cookbook provides three main recipes for installing Nginx.
- default.rb: Use this recipe if you have a native package for Nginx.
- repo.rb: The developer of Nginx also maintain stable packages for several platforms.
- 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.
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.
This recipe provides an Ohai plugin as a template. It is included by
both the default
and source
recipes.
Sets up configuration for the authorized_ip
nginx module.
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']
.
ipv6.rb
- enables IPv6 supporthttp_echo_module.rb
- downloads thehttp_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
- providesnginx_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 theupload_progress
module and enables it as a module when compiling nginx.
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.
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 nginxnode['nginx']['configure_arguments']
- options passed to ./configure when nginx was builtnode['nginx']['prefix']
- installation prefixnode['nginx']['conf_path']
- configuration file path
In the source recipe, it is used to determine whether control attributes for building nginx have changed.
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.
