Module description

Apache HTTP Server (also called Apache HTTPD, or simply Apache) is a widely used web server. This Puppet module simplifies the task of creating configurations to manage Apache servers in your infrastructure. It can configure and manage a range of virtual host setups and provides a streamlined way to install and configure Apache modules.

Setup

What the apache module affects:

• Configuration files and directories (created and written to)
  • WARNING: Configurations not managed by Puppet will be purged.
• Package/service/configuration files for Apache
• Apache modules
• Virtual hosts
• Listened-to ports
• /etc/make.conf on FreeBSD and Gentoo

On Gentoo, this module depends on the gentoo/puppet-portage Puppet module. Note that while several options apply or enable certain features and settings for Gentoo, it is not a supported operating system for this module.

Warning: This module modifies Apache configuration files and directories and purges any configuration not managed by Puppet. Apache configuration should be managed by Puppet, as unmanaged configuration files can cause unexpected failures.

To temporarily disable full Puppet management, set the purge_configs parameter in the apache class declaration to false. We recommend this only as a temporary means of saving and relocating customized configurations.

Beginning with Apache

To have Puppet install Apache with the default parameters, declare the apache class:

class { 'apache': }

When you declare this class with the default options, the module:

• Installs the appropriate Apache software package and required Apache modules for your operating system.
• Places the required configuration files in a directory, with the default location Depends on operating system.
• Configures the server with a default virtual host and standard port ('80') and address ('*') bindings.
• Creates a document root directory Depends on operating system, typically /var/www.
• Starts the Apache service.

Apache defaults depend on your operating system. These defaults work in testing environments but are not suggested for production. We recommend customizing the class's parameters to suit your site.

For instance, this declaration installs Apache without the apache module's default virtual host configuration, allowing you to customize all Apache virtual hosts:

class { 'apache':
  default_vhost => false,
}

Note: When default_vhost is set to false, you have to add at least one apache::vhost resource or Apache will not start. To establish a default virtual host, either set the default_vhost in the apache class or use the apache::vhost defined type. You can also configure additional specific virtual hosts with the apache::vhost defined type.

Usage

Configuring virtual hosts

The default apache class sets up a virtual host on port 80, listening on all interfaces and serving the docroot parameter's default directory of /var/www.

To configure basic name-based virtual hosts, specify the port and docroot parameters in the apache::vhost defined type:

apache::vhost { 'vhost.example.com':
  port    => '80',
  docroot => '/var/www/vhost',
}

See the apache::vhost defined type's reference for a list of all virtual host parameters.

Note: Apache processes virtual hosts in alphabetical order, and server administrators can prioritize Apache's virtual host processing by prefixing a virtual host's configuration file name with a number. The apache::vhost defined type applies a default priority of 15, which Puppet interprets by prefixing the virtual host's file name with 15-. This all means that if multiple sites have the same priority, or if you disable priority numbers by setting the priority parameter's value to false, Apache still processes virtual hosts in alphabetical order.

To configure user and group ownership for docroot, use the docroot_owner and docroot_group parameters:

apache::vhost { 'user.example.com':
  port          => '80',
  docroot       => '/var/www/user',
  docroot_owner => 'www-data',
  docroot_group => 'www-data',
}

Configuring virtual hosts with SSL

To configure a virtual host to use SSL encryption and default SSL certificates, set the ssl parameter. You must also specify the port parameter, typically with a value of '443', to accommodate HTTPS requests:

apache::vhost { 'ssl.example.com':
  port    => '443',
  docroot => '/var/www/ssl',
  ssl     => true,
}

To configure a virtual host to use SSL and specific SSL certificates, use the paths to the certificate and key in the ssl_cert and ssl_key parameters, respectively:

apache::vhost { 'cert.example.com':
  port     => '443',
  docroot  => '/var/www/cert',
  ssl      => true,
  ssl_cert => '/etc/ssl/fourth.example.com.cert',
  ssl_key  => '/etc/ssl/fourth.example.com.key',
}

To configure a mix of SSL and unencrypted virtual hosts at the same domain, declare them with separate apache::vhost defined types:

# The non-ssl virtual host
apache::vhost { 'mix.example.com non-ssl':
  servername => 'mix.example.com',
  port       => '80',
  docroot    => '/var/www/mix',
}

# The SSL virtual host at the same domain
apache::vhost { 'mix.example.com ssl':
  servername => 'mix.example.com',
  port       => '443',
  docroot    => '/var/www/mix',
  ssl        => true,
}

To configure a virtual host to redirect unencrypted connections to SSL, declare them with separate apache::vhost defined types and redirect unencrypted requests to the virtual host with SSL enabled:

apache::vhost { 'redirect.example.com non-ssl':
  servername      => 'redirect.example.com',
  port            => '80',
  docroot         => '/var/www/redirect',
  redirect_status => 'permanent',
  redirect_dest   => 'https://redirect.example.com/'
}

apache::vhost { 'redirect.example.com ssl':
  servername => 'redirect.example.com',
  port       => '443',
  docroot    => '/var/www/redirect',
  ssl        => true,
}

Configuring virtual host port and address bindings

Virtual hosts listen on all IP addresses ('*') by default. To configure the virtual host to listen on a specific IP address, use the ip parameter:

apache::vhost { 'ip.example.com':
  ip      => '127.0.0.1',
  port    => '80',
  docroot => '/var/www/ip',
}

You can also configure more than one IP address per virtual host by using an array of IP addresses for the ip parameter:

apache::vhost { 'ip.example.com':
  ip      => ['127.0.0.1','169.254.1.1'],
  port    => '80',
  docroot => '/var/www/ip',
}

You can configure multiple ports per virtual host by using an array of ports for the port parameter:

apache::vhost { 'ip.example.com':
  ip      => ['127.0.0.1'],
  port    => ['80','8080']
  docroot => '/var/www/ip',
}

To configure a virtual host with aliased servers, refer to the aliases using the serveraliases parameter:

apache::vhost { 'aliases.example.com':
  serveraliases => [
    'aliases.example.org',
    'aliases.example.net',
  ],
  port          => '80',
  docroot       => '/var/www/aliases',
}

To set up a virtual host with a wildcard alias for the subdomain mapped to a directory of the same name, such as 'http://example.com.loc' mapped to /var/www/example.com, define the wildcard alias using the serveraliases parameter and the document root with the virtual_docroot parameter:

apache::vhost { 'subdomain.loc':
  vhost_name      => '*',
  port            => '80',
  virtual_docroot => '/var/www/%-2+',
  docroot         => '/var/www',
  serveraliases   => ['*.loc',],
}

To configure a virtual host with filter rules, pass the filter directives as an array using the filters parameter:

apache::vhost { 'subdomain.loc':
  port    => '80',
  filters => [
    'FilterDeclare  COMPRESS',
    'FilterProvider COMPRESS DEFLATE resp=Content-Type $text/html',
    'FilterChain    COMPRESS',
    'FilterProtocol COMPRESS DEFLATE change=yes;byteranges=no',
  ],
  docroot => '/var/www/html',
}

Configuring virtual hosts for apps and processors

To set up a virtual host with suPHP, use the following parameters:

• suphp_engine, to enable the suPHP engine.
• suphp_addhandler, to define a MIME type.
• suphp_configpath, to set which path suPHP passes to the PHP interpreter.
• directory, to configure Directory, File, and Location directive blocks.

For example:

apache::vhost { 'suphp.example.com':
  port             => '80',
  docroot          => '/home/appuser/myphpapp',
  suphp_addhandler => 'x-httpd-php',
  suphp_engine     => 'on',
  suphp_configpath => '/etc/php5/apache2',
  directories      => [
    { 'path'  => '/home/appuser/myphpapp',
      'suphp' => {
        user  => 'myappuser',
        group => 'myappgroup',
      },
    },
  ],
}

To configure a virtual host to use the Web Server Gateway Interface (WSGI) for Python applications, use the wsgi set of parameters:

apache::vhost { 'wsgi.example.com':
  port                        => '80',
  docroot                     => '/var/www/pythonapp',
  wsgi_application_group      => '%{GLOBAL}',
  wsgi_daemon_process         => 'wsgi',
  wsgi_daemon_process_options => {
    processes    => '2',
    threads      => '15',
    display-name => '%{GROUP}',
  },
  wsgi_import_script          => '/var/www/demo.wsgi',
  wsgi_import_script_options  => {
    process-group     => 'wsgi',
    application-group => '%{GLOBAL}',
  },
  wsgi_process_group          => 'wsgi',
  wsgi_script_aliases         => { '/' => '/var/www/demo.wsgi' },
}

As of Apache 2.2.16, Apache supports FallbackResource, a simple replacement for common RewriteRules. You can set a FallbackResource using the fallbackresource parameter:

apache::vhost { 'wordpress.example.com':
  port             => '80',
  docroot          => '/var/www/wordpress',
  fallbackresource => '/index.php',
}

Note: The fallbackresource parameter only supports the 'disabled' value since Apache 2.2.24.

To configure a virtual host with a designated directory for Common Gateway Interface (CGI) files, use the scriptalias parameter to define the cgi-bin path:

apache::vhost { 'cgi.example.com':
  port        => '80',
  docroot     => '/var/www/cgi',
  scriptalias => '/usr/lib/cgi-bin',
}

To configure a virtual host for Rack, use the rack_base_uris parameter:

apache::vhost { 'rack.example.com':
  port           => '80',
  docroot        => '/var/www/rack',
  rack_base_uris => ['/rackapp1', '/rackapp2'],
}

Configuring IP-based virtual hosts

You can configure IP-based virtual hosts to listen on any port and have them respond to requests on specific IP addresses. In this example, the server listens on ports 80 and 81, because the example virtual hosts are not declared with a port parameter:

apache::listen { '80': }

apache::listen { '81': }

Configure the IP-based virtual hosts with the ip_based parameter:

apache::vhost { 'first.example.com':
  ip       => '10.0.0.10',
  docroot  => '/var/www/first',
  ip_based => true,
}

apache::vhost { 'second.example.com':
  ip       => '10.0.0.11',
  docroot  => '/var/www/second',
  ip_based => true,
}

You can also configure a mix of IP- and name-based virtual hosts in any combination of SSL and unencrypted configurations.

In this example, we add two IP-based virtual hosts on an IP address (in this example, 10.0.0.10). One uses SSL and the other is unencrypted:

apache::vhost { 'The first IP-based virtual host, non-ssl':
  servername => 'first.example.com',
  ip         => '10.0.0.10',
  port       => '80',
  ip_based   => true,
  docroot    => '/var/www/first',
}

apache::vhost { 'The first IP-based vhost, ssl':
  servername => 'first.example.com',
  ip         => '10.0.0.10',
  port       => '443',
  ip_based   => true,
  docroot    => '/var/www/first-ssl',
  ssl        => true,
}

Next, we add two name-based virtual hosts listening on a second IP address (10.0.0.20):

apache::vhost { 'second.example.com':
  ip      => '10.0.0.20',
  port    => '80',
  docroot => '/var/www/second',
}

apache::vhost { 'third.example.com':
  ip      => '10.0.0.20',
  port    => '80',
  docroot => '/var/www/third',
}

To add name-based virtual hosts that answer on either 10.0.0.10 or 10.0.0.20, you must disable the Apache default Listen 80, as it conflicts with the preceding IP-based virtual hosts. To do this, set the add_listen parameter to false:

apache::vhost { 'fourth.example.com':
  port       => '80',
  docroot    => '/var/www/fourth',
  add_listen => false,
}

apache::vhost { 'fifth.example.com':
  port       => '80',
  docroot    => '/var/www/fifth',
  add_listen => false,
}

Installing Apache modules

There are two ways to install Apache modules using the Puppet apache module:

• Use the apache::mod::<MODULE NAME> classes to install specific Apache modules with parameters.
• Use the apache::mod defined type to install arbitrary Apache modules.

Installing specific modules

The Puppet apache module supports installing many common Apache modules, often with parameterized configuration options. For a list of supported Apache modules, see the apache::mod::<MODULE NAME> class references.

For example, you can install the mod_ssl Apache module with default settings by declaring the apache::mod::ssl class:

class { 'apache::mod::ssl': }

apache::mod::ssl has several parameterized options that you can set when declaring it. For instance, to enable mod_ssl with compression enabled, set the ssl_compression parameter to true:

class { 'apache::mod::ssl':
  ssl_compression => true,
}

Note that some modules have prerequisites, which are documented in their references under apache::mod::<MODULE NAME>.

Installing arbitrary modules

You can pass the name of any module that your operating system's package manager can install to the apache::mod defined type to install it. Unlike the specific-module classes, the apache::mod defined type doesn't tailor the installation based on other installed modules or with specific parameters---Puppet only grabs and installs the module's package, leaving detailed configuration up to you.

For example, to install the mod_authnz_external Apache module, declare the defined type with the 'mod_authnz_external' name:

apache::mod { 'mod_authnz_external': }

There are several optional parameters you can specify when defining Apache modules this way. See the defined type's reference for details.

Configuring FastCGI servers to handle PHP files

Add the apache::fastcgi::server defined type to allow FastCGI servers to handle requests for specific files. For example, the following defines a FastCGI server at 127.0.0.1 (localhost) on port 9000 to handle PHP requests:

apache::fastcgi::server { 'php':
  host       => '127.0.0.1:9000',
  timeout    => 15,
  flush      => false,
  faux_path  => '/var/www/php.fcgi',
  fcgi_alias => '/php.fcgi',
  file_type  => 'application/x-httpd-php'
}

You can then use the custom_fragment parameter to configure the virtual host to have the FastCGI server handle the specified file type:

apache::vhost { 'www':
  ...
  custom_fragment => 'AddType application/x-httpd-php .php'
  ...
}

Load balancing examples

Apache supports load balancing across groups of servers through the mod_proxy Apache module. Puppet supports configuring Apache load balancing groups (also known as balancer clusters) through the apache::balancer and apache::balancermember defined types.

To enable load balancing with exported resources, export the apache::balancermember defined type from the load balancer member server:

@@apache::balancermember { "${::fqdn}-puppet00":
  balancer_cluster => 'puppet00',
  url              => "ajp://${::fqdn}:8009",
  options          => ['ping=5', 'disablereuse=on', 'retry=5', 'ttl=120'],
}

Then, on the proxy server, create the load balancing group:

apache::balancer { 'puppet00': }

To enable load balancing without exporting resources, declare the following on the proxy server:

apache::balancer { 'puppet00': }

apache::balancermember { "${::fqdn}-puppet00":
  balancer_cluster => 'puppet00',
  url              => "ajp://${::fqdn}:8009",
  options          => ['ping=5', 'disablereuse=on', 'retry=5', 'ttl=120'],
}

Then declare the apache::balancer and apache::balancermember defined types on the proxy server.

To use the ProxySet directive on the balancer, use the proxy_set parameter of apache::balancer:

apache::balancer { 'puppet01':
  proxy_set => {
    'stickysession' => 'JSESSIONID',
    'lbmethod'      => 'bytraffic',
  },
}

Load balancing scheduler algorithms (lbmethod) are listed in mod_proxy_balancer documentation.

Public Classes

Class: apache

Guides the basic setup and installation of Apache on your system.

When this class is declared with the default options, Puppet:

• Installs the appropriate Apache software package and required Apache modules for your operating system.
• Places the required configuration files in a directory, with the default location determined by your operating system.
• Configures the server with a default virtual host and standard port ('80') and address ('*') bindings.
• Creates a document root directory determined by your operating system, typically /var/www.
• Starts the Apache service.

You can simply declare the default apache class:

class { 'apache': }

allow_encoded_slashes

Sets the server default for the AllowEncodedSlashes declaration, which modifies the responses to URLs containing '\' and '/' characters. If not specified, this parameter omits the declaration from the server's configuration and uses Apache's default setting of 'off'.

Values: 'on', 'off', 'nodecode'.

Default: undef.

apache_version

Configures module template behavior, package names, and default Apache modules by defining the version of Apache to use. We do not recommend manually configuring this parameter without reason.

Default: Depends on operating system and release version detected by the apache::version class.

conf_dir

Sets the directory where the Apache server's main configuration file is located.

Default: Depends on operating system.

• Debian: /etc/apache2
• FreeBSD: /usr/local/etc/apache22
• Gentoo: /etc/apache2
• Red Hat: /etc/httpd/conf

conf_template

Defines the template used for the main Apache configuration file. Modifying this parameter is potentially risky, as the apache module is designed to use a minimal configuration file customized by conf.d entries.

Default: apache/httpd.conf.erb.

confd_dir

Sets the location of the Apache server's custom configuration directory.

Default: Depends on operating system.

• Debian: /etc/apache2/conf.d
• FreeBSD: /usr/local/etc/apache22
• Gentoo: /etc/apache2/conf.d
• Red Hat: /etc/httpd/conf.d

default_charset

Used as the AddDefaultCharset directive in the main configuration file.

Default: undef.

default_confd_files

Determines whether Puppet generates a default set of includable Apache configuration files in the directory defined by the confd_dir parameter. These configuration files correspond to what is typically installed with the Apache package on the server's operating system.

Boolean.

Default: true.

default_mods

Determines whether to configure and enable a set of default Apache modules depending on your operating system.

If false, Puppet includes only the Apache modules required to make the HTTP daemon work on your operating system, and you can declare any other modules separately using the apache::mod::<MODULE NAME> class or apache::mod defined type.

If true, Puppet installs additional modules, depending on the operating system and the values of apache_version and mpm_module parameters. Because these lists of modules can change frequently, consult the Puppet module's code for up-to-date lists.

If this parameter contains an array, Puppet instead enables all passed Apache modules.

Values: Boolean or an array of Apache module names.

Default: true.

default_ssl_ca

Sets the default certificate authority for the Apache server.

Although the default value results in a functioning Apache server, you must update this parameter with your certificate authority information before deploying this server in a production environment.

Boolean.

Default: undef.

default_ssl_cert

Sets the SSL encryption certificate location.

Although the default value results in a functioning Apache server, you must update this parameter with your certificate location before deploying this server in a production environment.

Default: Depends on operating system.

• Debian: /etc/ssl/certs/ssl-cert-snakeoil.pem
• FreeBSD: /usr/local/etc/apache22/server.crt
• Gentoo: /etc/ssl/apache2/server.crt
• Red Hat: /etc/pki/tls/certs/localhost.crt

default_ssl_chain

Sets the default SSL chain location.

Although this default value results in a functioning Apache server, you must update this parameter with your SSL chain before deploying this server in a production environment.

Default: undef.

default_ssl_crl

Sets the path of the default certificate revocation list (CRL) file to use.

Although this default value results in a functioning Apache server, you must update this parameter with the CRL file path before deploying this server in a production environment. You can use this parameter with or in place of the default_ssl_crl_path.

Default: undef.

default_ssl_crl_path

Sets the server's certificate revocation list path, which contains your CRLs.

Although this default value results in a functioning Apache server, you must update this parameter with the CRL file path before deploying this server in a production environment.

Default: undef.

default_ssl_crl_check

Sets the default certificate revocation check level via the SSLCARevocationCheck directive. This parameter applies only to Apache 2.4 or higher and is ignored on older versions.

Although this default value results in a functioning Apache server, you must specify this parameter when using certificate revocation lists in a production environment.

Default: undef.

default_ssl_key

Sets the SSL certificate key file location.

Although the default values result in a functioning Apache server, you must update this parameter with your SSL key's location before deploying this server in a production environment.

Default: Depends on operating system.

• Debian: /etc/ssl/private/ssl-cert-snakeoil.key
• FreeBSD: /usr/local/etc/apache22/server.key
• Gentoo: /etc/ssl/apache2/server.key
• Red Hat: /etc/pki/tls/private/localhost.key

default_ssl_vhost

Configures a default SSL virtual host.

If true, Puppet automatically configures the following virtual host using the apache::vhost defined type:

apache::vhost { 'default-ssl':
  port            => 443,
  ssl             => true,
  docroot         => $docroot,
  scriptalias     => $scriptalias,
  serveradmin     => $serveradmin,
  access_log_file => "ssl_${access_log_file}",
  }

Note: SSL virtual hosts only respond to HTTPS queries.

Boolean.

Default: false.

default_type

Apache 2.2 only. Sets the MIME content-type sent if the server cannot otherwise determine an appropriate content-type. This directive is deprecated in Apache 2.4 and newer, and is only for backwards compatibility in configuration files.

Default: undef.

default_vhost

Configures a default virtual host when the class is declared.

To configure customized virtual hosts, set this parameter's value to false.

Note: Apache will not start without at least one virtual host. If you set this to false you must configure a virtual host elsewhere.

Boolean.

Default: true.

dev_packages

Configures a specific dev package to use.

Values: A string or array of strings.

Example for using httpd 2.4 from the IUS yum repo:

include ::apache::dev
class { 'apache':
  apache_name  => 'httpd24u',
  dev_packages => 'httpd24u-devel',
}

Default: Depends on operating system.

• Red Hat: 'httpd-devel'
• Debian 8/Ubuntu 13.10 or newer: ['libaprutil1-dev', 'libapr1-dev', 'apache2-dev']
• Older Debian/Ubuntu versions: ['libaprutil1-dev', 'libapr1-dev', 'apache2-prefork-dev']
• FreeBSD, Gentoo: undef
• Suse: ['libapr-util1-devel', 'libapr1-devel']

docroot

Sets the default DocumentRoot location.

Default: Depends on operating system.

• Debian: /var/www/html
• FreeBSD: /usr/local/www/apache22/data
• Gentoo: /var/www/localhost/htdocs
• Red Hat: /var/www/html

error_documents

Determines whether to enable custom error documents on the Apache server.

Boolean.

Default: false.

group

Sets the group ID that owns any Apache processes spawned to answer requests.

By default, Puppet attempts to manage this group as a resource under the apache class, determining the group based on the operating system as detected by the apache::params class. To to prevent the group resource from being created and use a group created by another Puppet module, set the manage_group parameter's value to false.

Note: Modifying this parameter only changes the group ID that Apache uses to spawn child processes to access resources. It does not change the user that owns the parent server process.

httpd_dir

Sets the Apache server's base configuration directory. This is useful for specially repackaged Apache server builds but might have unintended consequences when combined with the default distribution packages.

Default: Depends on operating system.

• Debian: /etc/apache2
• FreeBSD: /usr/local/etc/apache22
• Gentoo: /etc/apache2
• Red Hat: /etc/httpd

http_protocol_options

Specifies the strictness of HTTP protocol checks.

Valid options: any sequence of the following alternative values: Strict or Unsafe, RegisteredMethods or LenientMethods, and Allow0.9 or Require1.0.

Default 'Strict LenientMethods Allow0.9'.

keepalive

Determines whether to enable persistent HTTP connections with the KeepAlive directive. If you set this to 'On', use the keepalive_timeout and max_keepalive_requests parameters to set relevant options.

Values: 'Off', 'On'.

Default: undef.

manage_group

When false, stops Puppet from creating the group resource.

If you have a group created from another Puppet module that you want to use to run Apache, set this to false. Without this parameter, attempting to use a previously established group results in a duplicate resource error.

Boolean.

Default: true.

supplementary_groups

Setting this to false is a stopgap measure to allow the apache module to coexist with existing or unmanaged configurations. We recommend moving your configuration to resources within this module. For virtual host configurations, see purge_vhost_dir.

Boolean.

Default: true.

purge_vhost_dir

If the vhost_dir parameter's value differs from the confd_dir parameter's, this parameter determines whether Puppet removes any configurations inside vhost_dir that are not managed by Puppet.

root_directory_secured

Sets the default access policy for the / directory in httpd.conf. A value of false allows access to all resources that are missing a more specific access policy. A value of true denies access to all resources by default. If true, more specific rules must be used to allow access to these resources (for example, in a directory block using the directories parameter).

Boolean.

Default: false.

vhost_dir

Changes your virtual host configuration files' location.

Default: Depends on operating system:

• Debian: /etc/apache2/sites-available

Default: '*'.

Some operating systems use a value of *.conf. By default, this module creates configuration files ending in .conf.

user

Changes the user that Apache uses to answer requests. Apache's parent process continues to run as root, but child processes access resources as the user defined by this parameter. To prevent Puppet from managing the user, set the manage_user parameter to false.

Default: Depends on the user set by apache::params class, based on your operating system:

• FreeBSD: 'www'
• Gentoo and Red Hat: 'apache'

To prevent Puppet from managing the user, set the manage_user parameter to false.

apache_name

Class: apache::mod::jk

Installs and manages mod_jk, a connector for Apache httpd redirection to old versions of TomCat and JBoss

Note: There is no official package available for mod_jk and thus it must be made available by means outside of the control of the apache module. Binaries can be found at Apache Tomcat Connectors download page

class { '::apache::mod::jk':
  ip           = '192.168.2.15',
  workers_file = 'conf/workers.properties',
  mount_file   = 'conf/uriworkermap.properties',
  shm_file     = 'run/jk.shm',
  shm_size     = '50M',
  $workers_file_content = {
    <Content>
  },
}

Parameters within apache::mod::jk:

The best source for understanding the mod_jk parameters is the official documentation, except for:

add_listen

Defines if a Listen directive according to parameters ip and port (see below), so that Apache listens to the IP/port combination and redirect to mod_jk. Useful when another Listen directive, like Listen *:<Port> or Listen <Port>, can conflict with the one necessary for mod_jk binding.

Type: Boolean Default: true

ip

IP for binding to mod_jk. Useful when the binding address is not the primary network interface IP.

Type: String Default: $facts['ipaddress']

port

Port for binding to mod_jk. Useful when something else, like a reverse proxy or cache, is receiving requests at port 80, then needs to forward them to Apache at a different port.

Type: String (numerical) Default: '80'

workers_file_content

Each directive has the format worker.<Worker name>.<Property>=<Value>. This maps as a hash of hashes, where the outer hash specifies workers, and each inner hash specifies each worker properties and values.
Plus, there are two global directives, 'worker.list' and 'worker.mantain'
For example, the workers file below:

worker.list = status
worker.list = some_name,other_name

worker.mantain = 60

# Optional comment
worker.some_name.type=ajp13
worker.some_name.socket_keepalive=true

# I just like comments
worker.other_name.type=ajp12 (why would you?)
worker.other_name.socket_keepalive=false

Should be parameterized as:

$workers_file_content = {
  worker_lists   => ['status', 'some_name,other_name'],
  worker_mantain => '60',
  some_name      => {
    comment          => 'Optional comment',
    type             => 'ajp13',
    socket_keepalive => 'true',
  },
  other_name     => {
    comment          => 'I just like comments',
    type             => 'ajp12',
    socket_keepalive => 'false',
  },
}

mount_file_content

Each directive has the format <URI> = <Worker name>. This maps as a hash of hashes, where the outer hash specifies workers, and each inner hash contains two items: uri_list - an array with URIs to be mapped to the worker - and comment - an optional string with a comment for the worker.
For example, the mount file below:

# Worker 1
/context_1/ = worker_1
/context_1/* = worker_1

# Worker 2
/ = worker_2
/context_2/ = worker_2
/context_2/* = worker_2

Should be parameterized as:

$mount_file_content = {
  worker_1 => {
    uri_list => ['/context_1/', '/context_1/*'],
    comment  => 'Worker 1',
  },
  worker_2 => {
    uri_list => ['/context_2/', '/context_2/*'],
    comment  => 'Worker 2',
  },
},

shm_file and log_file

Depending on how these files are specified, the class creates their final path differently:

• Relative path: prepends supplied path with logroot (see below)
• Absolute path or pipe: uses supplied path as-is

Examples (RHEL 6):

shm_file => 'shm_file'
# Ends up in
$shm_path = '/var/log/httpd/shm_file'

shm_file => '/run/shm_file'
# Ends up in
$shm_path = '/run/shm_file'

shm_file => '"|rotatelogs /var/log/httpd/mod_jk.log.%Y%m%d 86400 -180"'
# Ends up in
$shm_path = '"|rotatelogs /var/log/httpd/mod_jk.log.%Y%m%d 86400 -180"'

The default logroot is sane enough. Therefore, it is not recommended to specify absolute paths.

logroot

The base directory for shm_file and log_file is determined by the logroot parameter. If unspecified, defaults to apache::params::logroot.

The default logroot is sane enough. Therefore, it is not recommended to override it.
