##Overview
The Apache module allows you to set up virtual hosts and manage web services with minimal effort.
##Module Description
Apache is a widely-used web server, and this module provides a simplified way of creating configurations to manage your infrastructure. This includes the ability to configure and manage a range of different virtual host setups, as well as a streamlined way to install and configure Apache modules.
##Setup
What Apache affects:
- configuration files and directories (created and written to)
- NOTE: Configurations that are 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
###Beginning with Apache
To install Apache with the default parameters
class { 'apache': }
The defaults are determined by your operating system (e.g. Debian systems have one set of defaults, RedHat systems have another). These defaults will work well in a testing environment, but are not suggested for production. To establish customized parameters
class { 'apache':
default_mods => false,
default_confd_files => false,
}
###Configure a virtual host
Declaring the apache
class will create a default virtual host by setting up a vhost on port 80, listening on all interfaces and serving $apache::docroot
.
class { 'apache': }
To configure a very basic, name-based virtual host
apache::vhost { 'first.example.com':
port => '80',
docroot => '/var/www/first',
}
Note: The default priority is 15. If nothing matches this priority, the alphabetically first name-based vhost will be used. This is also true if you pass a higher priority and no names match anything else.
A slightly more complicated example, which moves the docroot owner/group
apache::vhost { 'second.example.com':
port => '80',
docroot => '/var/www/second',
docroot_owner => 'third',
docroot_group => 'third',
}
To set up a virtual host with SSL and default SSL certificates
apache::vhost { 'ssl.example.com':
port => '443',
docroot => '/var/www/ssl',
ssl => true,
}
To set up a virtual host with SSL and specific SSL certificates
apache::vhost { 'fourth.example.com':
port => '443',
docroot => '/var/www/fourth',
ssl => true,
ssl_cert => '/etc/ssl/fourth.example.com.cert',
ssl_key => '/etc/ssl/fourth.example.com.key',
}
To set up a virtual host with IP address different than '*'
apache::vhost { 'subdomain.example.com':
ip => '127.0.0.1',
port => '80',
docrout => '/var/www/subdomain',
}
To set up a virtual host with wildcard alias for subdomain mapped to same named directory
http://examle.com.loc => /var/www/example.com
apache::vhost { 'subdomain.loc':
vhost_name => '*',
port => '80',
virtual_docroot' => '/var/www/%-2+',
docroot => '/var/www',
serveraliases => ['*.loc',],
}
To set up a virtual host with suPHP
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 set up a virtual host with WSGI
apache::vhost { 'wsgi.example.com':
port => '80',
docroot => '/var/www/pythonapp',
wsgi_daemon_process => 'wsgi',
wsgi_daemon_process_options =>
{ processes => '2', threads => '15', display-name => '%{GROUP}' },
wsgi_process_group => 'wsgi',
wsgi_script_aliases => { '/' => '/var/www/demo.wsgi' },
}
Starting 2.2.16, httpd supports FallbackResource which is a simple replace for common RewriteRules:
apache::vhost { 'wordpress.example.com':
port => '80',
docroot => '/var/www/wordpress',
fallbackresource => '/index.php',
}
Please note that the disabled
argument to FallbackResource is only supported since 2.2.24.

##Usage
###Classes and Defined Types
This module modifies Apache configuration files and directories and will purge any configuration not managed by Puppet. Configuration of Apache should be managed by Puppet, as non-puppet configuration files can cause unexpected failures.
It is possible to temporarily disable full Puppet management by setting the purge_configs
parameter within the base apache
class to 'false'. This option should only be used as a temporary means of saving and relocating customized configurations.
####Class: apache
The Apache module's primary class, apache
, guides the basic setup of Apache on your system.
You may establish a default vhost in this class, the vhost
class, or both. You may add additional vhost configurations for specific virtual hosts using a declaration of the vhost
type.
Parameters within apache
:
#####default_mods
Sets up Apache with default settings based on your OS. Defaults to 'true', set to 'false' for customized configuration.
#####default_vhost
Sets up a default virtual host. Defaults to 'true', set to 'false' to set up customized virtual hosts.
#####default_confd_files
Generates default set of include-able apache configuration files under ${apache::confd_dir}
directory. These configuration files correspond to what is usually installed with apache package on given platform.
#####default_ssl_vhost
Sets up a default SSL virtual host. Defaults to 'false'.
apache::vhost { 'default-ssl':
port => 443,
ssl => true,
docroot => $docroot,
scriptalias => $scriptalias,
serveradmin => $serveradmin,
access_log_file => "ssl_${access_log_file}",
}
SSL vhosts only respond to HTTPS queries.
#####default_ssl_cert
The default SSL certification, which is automatically set based on your operating system (/etc/pki/tls/certs/localhost.crt
for RedHat, /etc/ssl/certs/ssl-cert-snakeoil.pem
for Debian, /usr/local/etc/apache22/server.crt
for FreeBSD). This default will work out of the box but must be updated with your specific certificate information before being used in production.
#####default_ssl_key
The default SSL key, which is automatically set based on your operating system (/etc/pki/tls/private/localhost.key
for RedHat, /etc/ssl/private/ssl-cert-snakeoil.key
for Debian, /usr/local/etc/apache22/server.key
for FreeBSD). This default will work out of the box but must be updated with your specific certificate information before being used in production.
#####default_ssl_chain
The default SSL chain, which is automatically set to 'undef'. This default will work out of the box but must be updated with your specific certificate information before being used in production.
#####default_ssl_ca
The default certificate authority, which is automatically set to 'undef'. This default will work out of the box but must be updated with your specific certificate information before being used in production.
#####default_ssl_crl_path
The default certificate revocation list path, which is automatically set to 'undef'. This default will work out of the box but must be updated with your specific certificate information before being used in production.
#####default_ssl_crl
The default certificate revocation list to use, which is automatically set to 'undef'. This default will work out of the box but must be updated with your specific certificate information before being used in production.
#####service_name
Name of apache service to run. Defaults to: 'httpd'
on RedHat, 'apache2'
on Debian, and 'apache22'
on FreeBSD.
#####service_enable
Determines whether the 'httpd' service is enabled when the machine is booted. Defaults to 'true'.
#####service_ensure
Determines whether the service should be running. Can be set to 'undef' which is useful when you want to let the service be managed by some other application like pacemaker. Defaults to 'running'.
#####purge_configs
Removes all other apache configs and vhosts, which is automatically set to true. Setting this to false is a stopgap measure to allow the apache module to coexist with existing or otherwise managed configuration. It is recommended that you move your configuration entirely to resources within this module.
#####serveradmin
Sets the server administrator. Defaults to 'root@localhost'.
#####servername
Sets the servername. Defaults to fqdn provided by facter.
#####server_root
A value to be set as ServerRoot
in main configuration file (httpd.conf
). Defaults to /etc/httpd
on RedHat, /etc/apache2
on Debian and /usr/local
on FreeBSD.
#####sendfile
Makes Apache use the Linux kernel 'sendfile' to serve static files. Defaults to 'On'.
#####server_root
A value to be set as ServerRoot
in main configuration file (httpd.conf
). Defaults to /etc/httpd
on RedHat and /etc/apache2
on Debian.
#####error_documents
Enables custom error documents. Defaults to 'false'.
#####httpd_dir
Changes the base location of the configuration directories used for the service. This is useful for specially repackaged HTTPD builds but may have unintended consequences when used in combination with the default distribution packages. Default is based on your OS.
#####confd_dir
Changes the location of the configuration directory your custom configuration files are placed in. Default is based on your OS.
#####vhost_dir
Changes the location of the configuration directory your virtual host configuration files are placed in. Default is based on your OS.
#####mod_dir
Changes the location of the configuration directory your Apache modules configuration files are placed in. Default is based on your OS.
#####mpm_module
Configures which mpm module is loaded and configured for the httpd process by the apache::mod::event
, apache::mod::itk
, apache::mod::peruser
, apache::mod::prefork
and apache::mod::worker
classes. Must be set to false
to explicitly declare apache::mod::event
, apache::mod::itk
, apache::mod::peruser
, apache::mod::prefork
or apache::mod::worker
classes with parameters. All possible values are event
, itk
, peruser
, prefork
, worker
(valid values depend on agent's OS), or the boolean false
. Defaults to prefork
on RedHat and FreeBSD and worker
on Debian. Note: on FreeBSD switching between different mpm modules is quite difficult (but possible). Before changing $mpm_module
one has to deinstall all packages that depend on currently installed apache
.
#####conf_template
Setting this allows you to override the template used for the main apache configuration file. This is a potentially risky thing to do as this module has been built around the concept of a minimal configuration file with most of the configuration coming in the form of conf.d/ entries. Defaults to 'apache/httpd.conf.erb'.
#####keepalive
Setting this allows you to enable persistent connections.
#####keepalive_timeout
Amount of time the server will wait for subsequent requests on a persistent connection. Defaults to '15'.
#####logroot
Changes the location of the directory Apache log files are placed in. Defaut is based on your OS.
#####log_level
Changes the verbosity level of the error log. Defaults to 'warn'. Valid values are emerg
, alert
, crit
, error
, warn
, notice
, info
or debug
.
#####ports_file
Changes the name of the file containing Apache ports configuration. Default is ${conf_dir}/ports.conf
.
#####server_tokens
Controls how much information Apache sends to the browser about itself and the operating system. See Apache documentation for 'ServerTokens'. Defaults to 'OS'.
#####server_signature
Allows the configuration of a trailing footer line under server-generated documents. See Apache documentation for 'ServerSignature'. Defaults to 'On'.
#####trace_enable
Controls, how TRACE requests per RFC 2616 are handled. See Apache documentation for 'TraceEnable'. Defaults to 'On'.
#####manage_user
Setting this to false will avoid the user resource to be created by this module. This is useful when you already have a user created in another puppet module and that you want to used it to run apache. Without this, it would result in a duplicate resource error.
#####manage_group
Setting this to false will avoid the group resource to be created by this module. This is useful when you already have a group created in another puppet module and that you want to used it for apache. Without this, it would result in a duplicate resource error.
#####package_ensure
Allow control over the package ensure statement. This is useful if you want to make sure apache is always at the latest version or whether it is only installed.
####Class: apache::default_mods
Installs default Apache modules based on what OS you are running
class { 'apache::default_mods': }
####Defined Type: apache::mod
Used to enable arbitrary Apache httpd modules for which there is no specific apache::mod::[name]
class. The apache::mod
defined type will also install the required packages to enable the module, if any.
apache::mod { 'rewrite': }
apache::mod { 'ldap': }
####Classes: apache::mod::[name]
There are many apache::mod::[name]
classes within this module that can be declared using include
:
alias
auth_basic
auth_kerb
autoindex
cache
cgi
cgid
dav
dav_fs
dav_svn
deflate
dev
dir
*disk_cache
event

rpaf
*setenvif
ssl
* (see apache::mod::ssl below)status
*suphp
userdir
*vhost_alias
worker
*wsgi
(see apache::mod::wsgi below)xsendfile
Modules noted with a * indicate that the module has settings and, thus, a template that includes parameters. These parameters control the module's configuration. Most of the time, these parameters will not require any configuration or attention.
The modules mentioned above, and other Apache modules that have templates, will cause template files to be dropped along with the mod install, and the module will not work without the template. Any mod without a template will install package but drop no files.
####Class: apache::mod::ssl
Installs Apache SSL capabilities and utilizes ssl.conf.erb
template. These are the defaults:
class { 'apache::mod::ssl':
ssl_compression => false,
ssl_options => [ 'StdEnvVars' ],
}
To use SSL with a virtual host, you must either set thedefault_ssl_vhost
parameter in apache
to 'true' or set the ssl
parameter in apache::vhost
to 'true'.
####Class: apache::mod::wsgi
class { 'apache::mod::wsgi':
wsgi_socket_prefix => "\${APACHE_RUN_DIR}WSGI",
wsgi_python_home => '/path/to/virtenv',
wsgi_python_path => '/path/to/virtenv/site-packages',
}
####Defined Type: apache::vhost
The Apache module allows a lot of flexibility in the set up and configuration of virtual hosts. This flexibility is due, in part, to vhost
's setup as a defined resource type, which allows it to be evaluated multiple times with different parameters.
The vhost
defined type allows you to have specialized configurations for virtual hosts that have requirements outside of the defaults. You can set up a default vhost within the base apache
class as well as set a customized vhost setup as default. Your customized vhost (priority 10) will be privileged over the base class vhost (15).
If you have a series of specific configurations and do not want a base apache
class default vhost, make sure to set the base class default host to 'false'.
class { 'apache':
default_vhost => false,
}
Parameters within apache::vhost
:
The default values for each parameter will vary based on operating system and type of virtual host.
#####access_log
Specifies whether *_access.log
directives should be configured. Valid values are 'true' and 'false'. Defaults to 'true'.
#####access_log_file
Points to the *_access.log
file. Defaults to 'undef'.
#####access_log_pipe
Specifies a pipe to send access log messages to. Defaults to 'undef'.
#####access_log_syslog
Sends all access log messages to syslog. Defaults to 'undef'.
#####access_log_format
Specifies either a LogFormat nickname or custom format string for access log. Defaults to 'undef'.
#####add_listen
Determines whether the vhost creates a listen statement. The default value is 'true'.
Setting add_listen
to 'false' stops the vhost from creating a listen statement, and this is important when you combine vhosts that are not passed an ip
parameter with vhosts that are passed the ip
parameter.
#####aliases
Passes a list of hashes to the vhost to create Alias
or AliasMatch
statements as per the mod_alias
documentation. Each hash is expected to be of the form:
aliases => [
{ aliasmatch => '^/image/(.*)\.jpg$', path => '/files/jpg.images/$1.jpg' }
{ alias => '/image', path => '/ftp/pub/image' },
],
For Alias
and AliasMatch
to work, each will need a corresponding <Directory /path/to/directory>
or <Location /path/to/directory>
block. The Alias
and AliasMatch
directives are created in the order specified in the aliases
paramter. As described in the mod_alias
documentation more specific Alias
or AliasMatch
directives should come before the more general ones to avoid shadowing.
Note: If apache::mod::passenger
is loaded and PassengerHighPerformance true
is set, then Alias
may have issues honouring the PassengerEnabled off
statement. See this article for details.
#####block
Specifies the list of things Apache will block access to. The default is an empty set, '[]'. Currently, the only option is 'scm', which blocks web access to .svn, .git and .bzr directories. To add to this, please see the Development section.
#####custom_fragment
Pass a string of custom configuration directives to be placed at the end of the vhost configuration.
#####default_vhost
Sets a given apache::vhost
as the default to serve requests that do not match any other apache::vhost
definitions. The default value is 'false'.
#####directories
Passes a list of hashes to the vhost to create <Directory /path/to/directory>...</Directory>
directive blocks as per the Apache core documentation. The path
key is required in these hashes. An optional provider
defaults to directory
. Usage will typically look like:
apache::vhost { 'sample.example.net':
docroot => '/path/to/directory',
directories => [
{ path => '/path/to/directory', <directive> => <value> },
{ path => '/path/to/another/directory', <directive> => <value> },
],
}
Note: At least one directory should match docroot
parameter, once you start declaring directories apache::vhost
assumes that all required <Directory>
blocks will be declared.
Note: If not defined a single default <Directory>
block will be created that matches the docroot
parameter.
provider
can be set to any of directory
, files
, or location
. If the pathspec starts with a ~
, httpd will interpret this as the equivalent of DirectoryMatch
, FilesMatch
, or LocationMatch
, respectively.
apache::vhost { 'files.example.net':
docroot => '/var/www/files',
directories => [
{ path => '~ (\.swp|\.bak|~)$', 'provider' => 'files', 'deny' => 'from all' },
],
}
The directives will be embedded within the Directory
(Files
, or Location
) directive block, missing directives should be undefined and not be added, resulting in their default vaules in Apache. Currently this is the list of supported directives:
######addhandlers

#####ip
The IP address the vhost listens on. Defaults to 'undef'.
#####ip_based
Enables an IP-based vhost. This parameter inhibits the creation of a NameVirtualHost directive, since those are used to funnel requests to name-based vhosts. Defaults to 'false'.
#####logroot
Specifies the location of the virtual host's logfiles. Defaults to /var/log/<apache log location>/
.
#####log_level
Specifies the verbosity level of the error log. Defaults to warn
for the global server configuration and can be overridden on a per-vhost basis using this parameter. Valid value for log_level

#####rack_base_uris
Specifies the resource identifiers for a rack configuration. The file paths specified will be listed as rack application roots for passenger/rack in the _rack.erb
template. Defaults to 'undef'.
#####redirect_dest
Specifies the address to redirect to. Defaults to 'undef'.
#####redirect_source
Specifies the source items? that will redirect to the destination specified in redirect_dest
. If more than one item for redirect is supplied, the source and destination must be the same length, and the items are order-dependent.
apache::vhost { 'site.name.fdqn':
…
redirect_source => ['/images','/downloads'],
redirect_dest => ['http://img.example.com/','http://downloads.example.com/'],
}
#####redirect_status
Specifies the status to append to the redirect. Defaults to 'undef'.
apache::vhost { 'site.name.fdqn':
…
redirect_status => ['temp','permanent'],
}
#####request_headers
Specifies additional request headers.
apache::vhost { 'site.name.fdqn':
…
request_headers => [
'append MirrorID "mirror 12"',
'unset MirrorID',
],
}
#####rewrite_base
Limits the rewrite_rule
to the specified base URL. Defaults to 'undef'.
apache::vhost { 'site.name.fdqn':
…
rewrite_rule => '^index\.html$ welcome.html',
rewrite_base => '/blog/',
}
The above example would limit the index.html -> welcome.html rewrite to only something inside of http://example.com/blog/.
#####rewrite_cond
Rewrites a URL via rewrite_rule
based on the truth of specified conditions. For example
apache::vhost { 'site.name.fdqn':
…
rewrite_cond => '%{HTTP_USER_AGENT} ^MSIE',
}
will rewrite URLs only if the visitor is using IE. Defaults to 'undef'.
Note: At the moment, each vhost is limited to a single list of rewrite conditions. In the future, you will be able to specify multiple rewrite_cond
and rewrite_rules
per vhost, so that different conditions get different rewrites.
#####rewrite_rule
Creates URL rewrite rules. Defaults to 'undef'. This parameter allows you to specify, for example, that anyone trying to access index.html will be served welcome.html.
apache::vhost { 'site.name.fdqn':
…
rewrite_rule => '^index\.html$ welcome.html',
}
#####scriptalias
Defines a directory of CGI scripts to be aliased to the path '/cgi-bin'
#####scriptaliases
Passes a list of hashes to the vhost to create ScriptAlias
or ScriptAliasMatch
statements as per the mod_alias
documentation. Each hash is expected to be of the form:
scriptaliases => [
{
alias => '/myscript',
path => '/usr/share/myscript',
},
{
aliasmatch => '^/foo(.*)',
path => '/usr/share/fooscripts$1',
},
{
aliasmatch => '^/bar/(.*)',
path => '/usr/share/bar/wrapper.sh/$1',
},
{
alias => '/neatscript',
path => '/usr/share/neatscript',
},
]
These directives are created in the order specified. As with Alias
and AliasMatch
directives the more specific aliases should come before the more general ones to avoid shadowing.
#####serveradmin
Specifies the email address Apache will display when it renders one of its error pages.
#####serveraliases
Sets the server aliases of the site.
#####servername
Sets the primary name of the virtual host.
#####setenv
Used by HTTPD to set environment variables for vhosts. Defaults to '[]'.
#####setenvif

#####ssl
Enables SSL for the virtual host. SSL vhosts only respond to HTTPS queries. Valid values are 'true' or 'false'.
#####ssl_ca
Specifies the certificate authority.
#####ssl_cert
Specifies the SSL certification.
#####ssl_protocol
Specifies the SSL Protocol (SSLProtocol).
#####ssl_cipher
Specifies the SSLCipherSuite.
#####ssl_honorcipherorder

An example:
apache::vhost { 'sample.example.net':
…
ssl_verify_client => 'optional',
}
#####ssl_verify_depth
Sets SSLVerifyDepth
directives as per the Apache Core documentation. Defaults to undef.
An example:
apache::vhost { 'sample.example.net':
…
ssl_verify_depth => 1,
}
#####ssl_options
Sets SSLOptions
directives as per the Apache Core documentation. This is the global setting for the vhost and can be a string or an array. Defaults to undef. A single string example:
apache::vhost { 'sample.example.net':
…
ssl_options => '+ExportCertData',
}
An array of strings example:
apache::vhost { 'sample.example.net':
…
ssl_options => [ '+StrictRequire', '+ExportCertData' ],
}
#####ssl_proxyengine
Specifies whether to use SSLProxyEngine
or not. Defaults to false
.
#####vhost_name
This parameter is for use with name-based virtual hosting. Defaults to '*'.
#####itk
Hash containing infos to configure itk as per the ITK documentation.
Keys could be:
- user + group
- assignuseridexpr
- assigngroupidexpr

}
###Virtual Host Examples
The Apache module allows you to set up pretty much any configuration of virtual host you might desire. This section will address some common configurations. Please see the Tests section for even more examples.
Configure a vhost with a server administrator
apache::vhost { 'third.example.com':
port => '80',
docroot => '/var/www/third',
serveradmin => '[email protected]',
}
Set up a vhost with aliased servers
apache::vhost { 'sixth.example.com':
serveraliases => [
'sixth.example.org',
'sixth.example.net',
],
port => '80',
docroot => '/var/www/fifth',
}
Configure a vhost with a cgi-bin
apache::vhost { 'eleventh.example.com':
port => '80',
docroot => '/var/www/eleventh',
scriptalias => '/usr/lib/cgi-bin',
}
Set up a vhost with a rack configuration
apache::vhost { 'fifteenth.example.com':
port => '80',
docroot => '/var/www/fifteenth',
rack_base_uris => ['/rackapp1', '/rackapp2'],
}
Set up a mix of SSL and non-SSL vhosts at the same domain
#The non-ssl vhost
apache::vhost { 'first.example.com non-ssl':
servername => 'first.example.com',
port => '80',
docroot => '/var/www/first',
}
#The SSL vhost at the same domain
apache::vhost { 'first.example.com ssl':
servername => 'first.example.com',
port => '443',
docroot => '/var/www/first',
ssl => true,
}
Configure a vhost to redirect non-SSL connections to SSL
apache::vhost { 'sixteenth.example.com non-ssl':
servername => 'sixteenth.example.com',
port => '80',
docroot => '/var/www/sixteenth',
redirect_status => 'permanent'
redirect_dest => 'https://sixteenth.example.com/'
}
apache::vhost { 'sixteenth.example.com ssl':
servername => 'sixteenth.example.com',
port => '443',
docroot => '/var/www/sixteenth',
ssl => true,
}
Set up IP-based vhosts on any listen port and have them respond to requests on specific IP addresses. In this example, we will set listening on ports 80 and 81. This is required because the example vhosts are not declared with a port parameter.
apache::listen { '80': }
apache::listen { '81': }
Then we will set up the IP-based vhosts
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,
}
Configure a mix of name-based and IP-based vhosts. First, we will add two IP-based vhosts on 10.0.0.10, one SSL and one non-SSL
apache::vhost { 'The first IP-based vhost, 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,
}
Then, we will add two name-based vhosts listening on 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',
}
If you want to add two name-based vhosts so that they will answer on either 10.0.0.10 or 10.0.0.20, you MUST declare add_listen => 'false'
to disable the otherwise automatic 'Listen 80', as it will conflict with the preceding IP-based vhosts.
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,
}
##Implementation
###Classes and Defined Types
####Class: apache::dev
Installs Apache development libraries
class { 'apache::dev': }
On FreeBSD you're required to define apache::package
or apache
class before apache::dev
.
####Defined Type: apache::listen
Controls which ports Apache binds to for listening based on the title:
apache::listen { '80': }
apache::listen { '443': }
Declaring this defined type will add all Listen
directives to the ports.conf
file in the Apache httpd configuration directory. apache::listen
titles should always take the form of: <port>
, <ipv4>:<port>
, or [<ipv6>]:<port>
Apache httpd requires that Listen
directives must be added for every port. The apache::vhost
defined type will automatically add Listen
directives unless the apache::vhost
is passed add_listen => false
.
####Defined Type: apache::namevirtualhost
Enables named-based hosting of a virtual host
class { 'apache::namevirtualhost`: }
Declaring this defined type will add all NameVirtualHost
directives to the ports.conf
file in the Apache https configuration directory. apache::namevirtualhost
titles should always take the form of: *
, *:<port>
, _default_:<port>
, <ip>
, or <ip>:<port>
.
####Defined Type: apache::balancermember
Define members of a proxy_balancer set (mod_proxy_balancer). Very useful when using exported resources.
On every app server you can export a balancermember like this:
@@apache::balancermember { "${::fqdn}-puppet00":
balancer_cluster => 'puppet00',
url => "ajp://${::fqdn}:8009"
options => ['ping=5', 'disablereuse=on', 'retry=5', 'ttl=120'],
}
And on the proxy itself you create the balancer cluster using the defined type apache::balancer:
apache::balancer { 'puppet00': }
If you need to use ProxySet in the balncer config you can do as so:
apache::balancer { 'puppet01':
proxy_set => {'stickysession' => 'JSESSIONID'},
}
###Templates
The Apache module relies heavily on templates to enable the vhost
and apache::mod
defined types. These templates are built based on Facter facts around your operating system. Unless explicitly called out, most templates are not meant for configuration.
##Limitations
This has been tested on Ubuntu Precise, Debian Wheezy, CentOS 5.8, and FreeBSD 9.1.
##Development
Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.
We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.
You can read the complete module contribution guide on the Puppet Labs wiki.
This project contains tests for both rspec-puppet and rspec-system to verify functionality. For in-depth information please see their respective documentation.
Quickstart:
gem install bundler
bundle install
bundle exec rake spec
bundle exec rake spec:system
