NGINX Module

James Fryman james@frymanet.com

This module manages NGINX configuration.

Quick Start

Install and bootstrap an NGINX instance

class { 'nginx': }

Setup a new virtual host

nginx::resource::vhost { 'www.puppetlabs.com':
  www_root => '/var/www/www.puppetlabs.com',
}

Add a Proxy Server

nginx::resource::upstream { 'puppet_rack_app':
  members => [
    'localhost:3000',
    'localhost:3001',
    'localhost:3002',
  ],
}

nginx::resource::vhost { 'rack.puppetlabs.com':
  proxy => 'http://puppet_rack_app',
}

Add a smtp proxy

class { 'nginx':
  mail => true,
}

nginx::resource::mailhost { 'domain1.example':
  auth_http   => 'server2.example/cgi-bin/auth',
  protocol    => 'smtp',
  listen_port => 587,
  ssl_port    => 465,
  starttls    => 'only',
  xclient     => 'off',
  ssl         => true,
  ssl_cert    => '/tmp/server.crt',
  ssl_key     => '/tmp/server.pem',
}

SSL configuration

By default, creating a vhost resource will only create a HTTP vhost. To also create a HTTPS (SSL-enabled) vhost, set ssl => true on the vhost. You will have a HTTP server listening on listen_port (port 80 by default) and a HTTPS server listening on ssl_port (port 443 by default). Both vhosts will have the same server_name and a similar configuration.

To create only a HTTPS vhost, set ssl => true and also set listen_port to the same value as ssl_port. Setting these to the same value disables the HTTP vhost. The resulting vhost will be listening on ssl_port.

Locations

Locations require specific settings depending on whether they should be included in the HTTP, HTTPS or both vhosts.

HTTP only vhost (default)

If you only have a HTTP vhost (i.e. ssl => false on the vhost) maks sure you don't set ssl => true on any location you associate with the vhost.

HTTP and HTTPS vhost

If you set ssl => true and also set listen_port and ssl_port to different values on the vhost you will need to be specific with the location settings since you will have a HTTP vhost listening on listen_port and a HTTPS vhost listening on ssl_port:

• To add a location to only the HTTP server, set ssl => false on the location (this is the default).
• To add a location to both the HTTP and HTTPS server, set ssl => true on the location, and ensure ssl_only => false (which is the default value for ssl_only).
• To add a location only to the HTTPS server, set both ssl => true and ssl_only => true on the location.

HTTPS only vhost

If you have set ssl => true and also set listen_port and ssl_port to the same value on the vhost, you will have a single HTTPS vhost listening on ssl_port. To add a location to this vhost set ssl => true and ssl_only => true on the location.

Hiera Support

Defining nginx resources in Hiera.

nginx::nginx_upstreams:
  'puppet_rack_app':
    ensure: present
    members:
      - localhost:3000
      - localhost:3001
      - localhost:3002
nginx::nginx_vhosts:
  'www.puppetlabs.com':
    www_root: '/var/www/www.puppetlabs.com'
  'rack.puppetlabs.com':
    proxy: 'http://puppet_rack_app'
nginx::nginx_locations:
  'static':
    location: '~ "^/static/[0-9a-fA-F]{8}\/(.*)$"'
    vhost: www.puppetlabs.com
  'userContent':
    location: /userContent
    vhost: www.puppetlabs.com
    www_root: /var/www/html

Nginx with precompiled Passenger

Currently this works only for Debian family.

class { 'nginx':
  package_source  => 'passenger',
  http_cfg_append => {
    'passenger_root' => '/usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini',
  }
}

Package source passenger will add Phusion Passenger repository to APT sources. For each virtual host you should specify which ruby should be used.

nginx::resource::vhost { 'www.puppetlabs.com':
  www_root         => '/var/www/www.puppetlabs.com',
  vhost_cfg_append => {
    'passenger_enabled' => 'on',
    'passenger_ruby'    => '/usr/bin/ruby',
  }
}

Puppet master served by Nginx and Passenger

Virtual host config for serving puppet master:

nginx::resource::vhost { 'puppet':
  ensure               => present,
  server_name          => ['puppet'],
  listen_port          => 8140,
  ssl                  => true,
  ssl_cert             => '/var/lib/puppet/ssl/certs/example.com.pem',
  ssl_key              => '/var/lib/puppet/ssl/private_keys/example.com.pem',
  ssl_port             => 8140,
  vhost_cfg_append     => {
    'passenger_enabled'      => 'on',
    'passenger_ruby'         => '/usr/bin/ruby',
    'ssl_crl'                => '/var/lib/puppet/ssl/ca/ca_crl.pem',
    'ssl_client_certificate' => '/var/lib/puppet/ssl/certs/ca.pem',
    'ssl_verify_client'      => 'optional',
    'ssl_verify_depth'       => 1,
  },
  www_root             => '/etc/puppet/rack/public',
  use_default_location => false,
  access_log           => '/var/log/nginx/puppet_access.log',
  error_log            => '/var/log/nginx/puppet_error.log',
  passenger_cgi_param  => {
    'HTTP_X_CLIENT_DN'     => '$ssl_client_s_dn',
    'HTTP_X_CLIENT_VERIFY' => '$ssl_client_verify',
  },
}
