This cookbook provides a complete Debian/Ubuntu style Apache HTTPD
|
|
configuration. Non-Debian based distributions such as Red Hat/CentOS,
|
|
ArchLinux and others supported by this cookbook will have a
|
|
configuration that mimics Debian/Ubuntu style as it is easier to
|
|
manage with Chef.
|
|
|
|
Debian-style Apache configuration uses scripts to manage modules and
|
|
sites (vhosts). The scripts are:
|
|
|
|
* a2ensite
|
|
* a2dissite
|
|
* a2enmod
|
|
* a2dismod
|
|
* a2enconf
|
|
* a2disconf
|
|
|
|
This cookbook ships with templates of these scripts for non
|
|
Debian/Ubuntu platforms. The scripts are used in the __Definitions__
|
|
below.
|
|
|
|
## Cookbooks:
|
|
|
|
This cookbook has no direct external dependencies.
|
|
|
|
Depending on your OS configuration and security policy, you may need
|
|
additional recipes or cookbooks for this cookbook's recipes to
|
|
converge on the node. In particular, the following Operating System
|
|
settings may affect the behavior of this cookbook:
|
|
|
|
* apt cache outdated
|
|
* SELinux enabled
|
|
* firewalls (such as iptables, ufw, etc.)
|
|
* Compile tools
|
|
* 3rd party repositories
|
|
|
|
On Ubuntu/Debian, use [apt](https://supermarket.chef.io/cookbooks/apt) cookbook to ensure the package
|
|
cache is updated so Chef can install packages, or consider putting
|
|
apt-get in your bootstrap process or
|
|
[knife bootstrap template](http://docs.chef.io/knife_bootstrap.html)
|
|
|
|
On RHEL, SELinux is enabled by default. The [selinux](https://supermarket.chef.io/cookbooks/selinux) cookbook
|
|
contains a `permissive` recipe that can be used to set SELinux to
|
|
"Permissive" state. Otherwise, additional recipes need to be created
|
|
by the user to address SELinux permissions.
|
|
|
|
|
|
To deal with firewalls Chef Software does provide an [iptables](https://supermarket.chef.io/cookbooks/iptables) and [ufw](https://supermarket.chef.io/cookbooks/ufw) cookbook but is migrating from the approach used there to a more robust solution
|
|
utilizing the general [firewall](https://supermarket.chef.io/cookbooks/firewall) cookbook to setup rules.
|
|
See those cookbooks' READMEs for documentation.
|
|
|
|
Build/compile tools may not be installed on the system by default.
|
|
Some recipes (e.g., `apache2::mod_auth_openid`) build the module from
|
|
source. Use the [build-essential](https://supermarket.chef.io/cookbooks/build-essential) cookbook to get essential
|
|
build packages installed.
|
|
|
|
On ArchLinux, if you are using the `apache2::mod_auth_openid` recipe,
|
|
you also need the [pacman](https://supermarket.chef.io/cookbooks/pacman) cookbook for the `pacman_aur` LWRP. Put
|
|
`recipe[pacman]` on the node's expanded run list (on the node or in a
|
|
role). This is not an explicit dependency because it is only required
|
|
for this single recipe and platform; the pacman default recipe
|
|
performs `pacman -Sy` to keep pacman's package cache updated.
|
|
|
|
## Platforms:
|
|
|
|
The following platforms and versions are tested and supported using
|
|
[test-kitchen](http://kitchen.ci/)
|
|
|
|
* Ubuntu 14.04
|
|
* Ubuntu 16.04
|
|
* Debian 8.6
|
|
* CentOS 7.3
|
|
* Fedora 25
|
|
|
|
The following platform families are supported in the code, and are
|
|
assumed to work based on the successful testing on Ubuntu and CentOS.
|
|
|
|
* Red Hat (rhel)
|
|
|
|
The following platforms are also supported in the code, have been
|
|
tested manually but are not regularly tested under test-kitchen.
|
|
|
|
* Amazon Linux
|
|
* SUSE/OpenSUSE
|
|
* ArchLinux
|
|
* FreeBSD
|
|
|
|
### Notes for RHEL Family:
|
|
|
|
On Red Hat Enterprise Linux and derivatives, the EPEL repository may
|
|
be necessary to install packages used in certain recipes. The
|
|
`apache2::default` recipe, however, does not require any additional
|
|
repositories. The [yum-epel](https://supermarket.chef.io/cookbooks/yum-epel) cookbook can be used to add the
|
|
EPEL repository. See __Examples__ for more information.
|
|
|
|
Usage
|
|
=====
|
|
|
|
Using this cookbook is relatively straightforward. It is recommended to create
|
|
a project or organization specific [wrapper cookbook](https://www.chef.io/blog/2013/12/03/doing-wrapper-cookbooks-right/)
|
|
and add the desired recipes to the run list of a node, or create a role. Depending on your
|
|
environment, you may have multiple roles that use different recipes
|
|
from this cookbook. Adjust any attributes as desired. For example, to
|
|
create a basic role for web servers that provide both HTTP and HTTPS:
|
|
|
|
```ruby
|
|
% cat roles/webserver.rb
|
|
name "webserver"
|
|
description "Systems that serve HTTP and HTTPS"
|
|
run_list(
|
|
"recipe[apache2]",
|
|
"recipe[apache2::mod_ssl]"
|
|
)
|
|
default_attributes(
|
|
"apache" => {
|
|
"listen" => ["*:80", "*:443"]
|
|
}
|
|
)
|
|
```
|
|
|
|
For examples of using the definitions in your own recipes, see their
|
|
respective sections below.
|
|
|
|
|
|

These are general settings used in recipes and templates. Default
|
|
values are noted.
|
|
|
|
* `node['apache']['version']` - Specifing 2.4 triggers apache 2.4 support. If the platform is known during our test to install 2.4 by default, it will be set to 2.4 for you. Otherwise it falls back to 2.2. This value should be specified as a string.

|
|
|
|
The modules listed in `default_modules` will be included as recipes in `recipe[apache::default]`.
|
|
|
|
Prefork attributes
|
|
------------------
|
|
|
|
Prefork attributes are used for tuning the Apache HTTPD [prefork MPM](http://httpd.apache.org/docs/current/mod/prefork.html) configuration.
|
|
|
|
* `node['apache']['prefork']['startservers']` - initial number of server processes to start. Default is 16.

|
|
|
|
Worker attributes
|
|
-----------------
|
|
|
|
Worker attributes are used for tuning the Apache HTTPD [worker MPM](http://httpd.apache.org/docs/current/mod/worker.html)
|
|
configuration.
|
|
|
|
* `node['apache']['worker']['startservers']` - Initial number of server processes to start. Default 4
|
|
* `node['apache']['worker']['serverlimit']` - Upper limit on configurable server processes. Default 16.
|

Event attributes
|
|
----------------
|
|
|
|
Event attributes are used for tuning the Apache HTTPD [event MPM](http://httpd.apache.org/docs/current/mod/event.html)
|
|
configuration.
|

|
|
* `node['apache']['event']['maxconnectionsperchild']` - Limit on the number of connections that an individual child server will handle during its life.
|
|
|
|
Other/Unsupported MPM
|
|
---------------------
|
|
|
|
To use the cookbook with an unsupported mpm (other than prefork, event or worker):
|
|
|
|
* set `node['apache']['mpm']` to the name of the module (e.g. `itk`)
|
|
* in your cookbook, after `include_recipe 'apache2'` use the `apache_module` definition to enable/disable the required module(s)
|
|
|
|
Module specific attributes
|
|
--------------------------
|
|
|
|
Some module recipes have their own attributes that can be used to alter and modify the behavior of this cookbook. Please see the sections for the indivual modules below for more information on those attributes.
|
|
|
|
|
|
|
|
Recipes
|
|
=======
|
|
|
|
Most of the recipes in the cookbook are for enabling Apache modules.
|
|
Where additional configuration or behavior is used, it is documented
|
|
below in more detail.
|
|
|
|
The following recipes merely enable the specified module: `mod_actions`, `mod_alias`,
|
|
`mod_auth_basic`, `mod_auth_digest`, `mod_authn_file`, `mod_authnz_ldap`,
|
|
`mod_authz_default`, `mod_authz_groupfile`, `mod_authz_host`,
|
|
`mod_authz_user`, `mod_autoindex`, `mod_cgi`, `mod_dav_fs`,
|
|
`mod_dav_svn`, `mod_deflate`, `mod_dir`, `mod_env`, `mod_expires`,
|
|
`mod_headers`, `mod_ldap`, `mod_log_config`, `mod_mime`,
|
|
`mod_negotiation`, `mod_proxy`, `mod_proxy_ajp`, `mod_proxy_balancer`,
|
|
`mod_proxy_connect`, `mod_proxy_http`, `mod_python`, `mod_rewrite`,
|
|
`mod_setenvif`, `mod_status`, `mod_wsgi`, `mod_xsendfile`.
|
|
|
|
On RHEL Family distributions, certain modules ship with a config file
|
|
with the package. The recipes here may delete those configuration
|
|
files to ensure they don't conflict with the settings from the
|
|
cookbook, which will use per-module configuration in
|
|
`/etc/httpd/mods-enabled`.
|
|
|
|
default
|
|
-------
|
|
|
|
The default recipe does a number of things to set up Apache HTTPd. It
|
|
also includes a number of modules based on the attribute
|
|
`node['apache']['default_modules']` as recipes.
|
|
|
|
mod\_auth\_cas
|
|
--------------
|
|
|
|
This recipe installs the proper package and enables the `auth_cas`
|
|
module. It can install from source or package. Package is the default,
|
|
set the attribute `node['apache']['mod_auth_cas']['from_source']` to
|
|
true to enable source installation. Modify the version to install by
|
|
changing the attribute
|
|
`node['apache']['mod_auth_cas']['source_revision']`. It is a version
|
|
tag by default, but could be master, or another tag, or branch.
|
|
|
|
The module configuration is written out with the `CASCookiePath` set,
|
|
otherwise an error loading the module may cause Apache to not start.
|
|
|
|
**Note**: This recipe does not work on EL 6 platforms unless
|
|
epel-testing repository is enabled (outside the scope of this
|
|
cookbook), or the package version 1.0.8.1-3.el6 or higher is otherwise
|
|
available to the system due to this bug:
|
|
|
|
https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=708550
|
|
|
|
mod\_auth\_openid
|
|
-----------------
|
|
|
|
This recipe compiles the module from source. In addition to
|
|
`build-essential`, some other packages are included for installation
|
|
like the GNU C++ compiler and development headers.
|
|
|
|
To use the module in your own cookbooks to authenticate systems using
|
|
OpenIDs, specify an array of OpenIDs that are allowed to authenticate
|
|
with the attribute `node['apache']['allowed_openids']`. Use the
|
|
following in a vhost to protect with OpenID authentication:
|
|
|
|
AuthType OpenID require user <%= node['apache']['allowed_openids'].join(' ') %>
|
|
AuthOpenIDDBLocation <%= node['apache']['mod_auth_openid']['dblocation'] %>
|
|
|
|
Change the DBLocation with the attribute as required; this file is in
|
|
a different location than previous versions, see below. It should be a
|
|
sane default for most platforms, though, see
|
|
`attributes/mod_auth_openid.rb`.
|
|
|
|
The following attributes are in the `attributes/mod_auth_openid.rb` file.
|
|
|
|
* `node['apache']['mod_auth_openid']['checksum']` - sha256sum of the tarball containing the source.
|
|
* `node['apache']['mod_auth_openid']['ref']` - Any sha, tag, or branch found from https://github.com/bmuller/mod_auth_openid
|
|
* `node['apache']['mod_auth_openid']['version']` - directory name version within the tarball
|
|
* `node['apache']['mod_auth_openid']['cache_dir']` - the cache directory is where the sqlite3 database is stored. It is separate so it can be managed as a directory resource.
|
|
* `node['apache']['mod_auth_openid']['dblocation']` - filename of the sqlite3 database used for directive `AuthOpenIDDBLocation`, stored in the `cache_dir` by default.
|
|
* `node['apache']['mod_auth_openid']['configure_flags']` - optional array of configure flags passed to the `./configure` step in the compilation of the module.
|
|
|
|
|
|
mod\_fastcgi
|
|
------------
|
|
|
|
Install the fastcgi package and enable the module.
|
|
|
|
Note: In Ubuntu 14.04, the `libapache2-mod-fastcgi` module is not available by default due to the [Multiverse](https://help.ubuntu.com/community/Repositories/Ubuntu) repositories.
|
|
You need to enable the multiverse repositories either from `/etc/apt/sources.list` or use the [apt](https://supermarket.chef.io/cookbooks/apt) cookbook.
|
|
|
|
mod\_fcgid
|
|
----------
|
|
|
|
Installs the fcgi package and enables the module. Requires EPEL on
|
|
RHEL family.
|
|
|
|
mod\_php5
|
|
--------
|
|
|
|
Simply installs the appropriate package on Debian, Ubuntu and
|
|
ArchLinux.
|
|
|
|
On Red Hat family distributions including Fedora, the php.conf that
|
|
comes with the package is removed. On RHEL platforms less than v6, the
|
|
`php53` package is used.
|
|
|
|
* `node['apache']['mod_php5']['install_method']` - default `package` can be overridden to avoid package installs.
|
|
|
|
mod\_ssl
|
|
--------
|
|
|
|
Besides installing and enabling `mod_ssl`, this recipe will append
|
|
port 443 to the `node['apache']['listen']` attributes for all addresses and
|
|
update the ports.conf.
|
|
|
|
|
|
* `node['apache']['mod_ssl']['cipher_suite']` - sets the SSLCiphersuite value to the specified string. The default is
|
|
considered "sane" but you may need to change it for your local security policy, e.g. if you have PCI-DSS requirements. Additional
|
|
commentary on the
|
|
[original pull request](https://github.com/sous-chefs/apache2/pull/15#commitcomment-1605406).
|
|
* `node['apache']['mod_ssl']['honor_cipher_order']` - Option to prefer the server's cipher preference order. Default 'On'.
|
|
* `node['apache']['mod_ssl']['insecure_renegotiation']` - Option to enable support for insecure renegotiation. Default 'Off'.
|
|
* `node['apache']['mod_ssl']['strict_sni_vhost_check']` - Whether to allow non-SNI clients to access a name-based virtual host. Default 'Off'.
|
|
* `node['apache']['mod_ssl']['session_cache']` - Configures the OCSP stapling cache. Default `shmcb:/var/run/apache2/ssl_scache`
|
|
* `node['apache']['mod_ssl']['session_cache_timeout']` - Number of seconds before an SSL session expires in the Session Cache. Default 300.
|
|
* `node['apache']['mod_ssl']['compression']` - Enable compression on the SSL level. Default 'Off'.
|
|
* `node['apache']['mod_ssl']['use_stapling']` - Enable stapling of OCSP responses in the TLS handshake. Default 'Off'.
|
|
* `node['apache']['mod_ssl']['stapling_responder_timeout']` - Timeout for OCSP stapling queries. Default 5
|
|
* `node['apache']['mod_ssl']['stapling_return_responder_errors']` - Pass stapling related OCSP errors on to client. Default 'Off'
|
|
* `node['apache']['mod_ssl']['stapling_cache']` - Configures the OCSP stapling cache. Default `shmcb:/var/run/ocsp(128000)`
|
|
* `node['apache']['mod_ssl']['pass_phrase_dialog']` - Configures SSLPassPhraseDialog. Default `builtin`
|
|
* `node['apache']['mod_ssl']['mutex']` - Configures SSLMutex. Default `file:/var/run/apache2/ssl_mutex`
|
|
* `node['apache']['mod_ssl']['directives']` - Hash for add any custom directive.

Definitions
|
|
===========
|
|
|
|
The cookbook provides a few definitions. At some point in the future
|
|
these definitions will be refactored into custom resources see
|
|
[issue 414](https://github.com/sous-chefs/apache2/issues/414).
|
|
|
|
apache\_conf
|
|
------------
|
|
|
|
Writes conf files to the `conf-available` folder, and passes enabled values to `apache_config`.
|
|
|
|
This definition should generally be called over `apache_config`.
|
|
|
|
### Parameters:
|
|
|
|
* `name` - Name of the config placed and enabled or disabled with the `a2enconf` or `a2disconf` scripts.
|
|
* `enable` - Default true, which uses `a2enconf` to enable the config. If false, the config will be disabled with `a2disconf`.
|
|
* `conf_path` - path to put the config in if you need to override the default `conf-available`.
|
|
* `source` - The source configuration template name. The default value is `params[:name].conf.erb`
|
|
* `cookbook` - The cookbook in which the configuration template is located. The default value is the current cookbook.
|
|
|
|
### Examples:
|
|
|
|
Place and enable the example conf:
|
|
|
|
```ruby
|
|
apache_conf 'example' do
|
|
enable true
|
|
end
|
|
```
|
|
|
|
Place and disable (or never enable to begin with) the example conf:
|
|
|
|
```ruby
|
|
apache_conf 'example' do
|
|
enable false
|
|
end
|
|
```
|
|
|
|
Place the example conf, which has a different path than the default (conf-*):
|
|
|
|
```ruby
|
|
apache_conf 'example' do
|
|
conf_path '/random/example/path'
|
|
enable false
|
|
end
|
|
```
|
|
|
|
|
|
apache\_config (internal)
|
|
--------------------------
|
|
|
|
Sets up configuration file for Apache from a template. The
|
|
template should be in the same cookbook where the definition is used. This is used by the `apache_conf` definition and should not be used directly.
|
|
|
|
It will use `a2enconf` and `a2disconf` to control the symlinking of configuration files between `conf-available` and `conf-enabled`.
|
|
|
|
Enable or disable an Apache config file in
|
|
`#{node['apache']['dir']}/conf-available` by calling `a2enconf` or
|
|
`a2disconf` to manage the symbolic link in
|
|
`#{node['apache']['dir']}/conf-enabled`. These config files should be created in your cookbook, and placed on the system using `apache_conf`
|
|
|
|
### Parameters:
|
|
|
|
* `name` - Name of the config enabled or disabled with the `a2enconf` or `a2disconf` scripts.
|
|
* `source` - The location of a template file. The default `name.erb`.
|
|
* `cookbook` - The cookbook in which the configuration template is located (if it is not located in the current cookbook). The default value is the current cookbook.
|
|
* `enable` - Default true, which uses `a2enconf` to enable the config. If false, the config will be disabled with `a2disconf`.
|
|
|
|
### Examples:
|
|
|
|
Enable the example config.
|
|
|
|
```ruby
|
|
apache_config 'example' do
|
|
enable true
|
|
end
|
|
```
|
|
|
|
Disable a module:
|
|
|
|
```ruby
|
|
apache_config 'disabled_example' do
|
|
enable false
|
|
end
|
|
```
|
|
|
|
See the recipes directory for many more examples of `apache_config`.
|
|
|
|
|
|
apache\_module
|
|
--------------
|
|
|
|
Enable or disable an Apache module in
|
|
`#{node['apache']['dir']}/mods-available` by calling `a2enmod` or
|
|
`a2dismod` to manage the symbolic link in
|
|
`#{node['apache']['dir']}/mods-enabled`. If the module has a
|
|
configuration file, a template should be created in the cookbook where
|
|
the definition is used. See __Examples__.
|
|
|
|
### Parameters:
|
|
|
|
* `name` - Name of the module enabled or disabled with the `a2enmod` or `a2dismod` scripts.
|
|
* `identifier` - String to identify the module for the `LoadModule` directive. Not typically needed, defaults to `#{name}_module`
|
|
* `enable` - Default true, which uses `a2enmod` to enable the module. If false, the module will be disabled with `a2dismod`.
|
|
* `conf` - Default false. Set to true if the module has a config file, which will use `apache_mod` for the file.
|
|
* `filename` - specify the full name of the file, e.g.
|
|
|
|
### Examples:
|
|
|
|
Enable the ssl module, which also has a configuration template in `templates/default/mods/ssl.conf.erb`.
|
|
|
|
```ruby
|
|
apache_module "ssl" do
|
|
conf true
|
|
end
|
|
```
|
|
|
|
Enable the php5 module, which has a different filename than the module default:
|
|
|
|
```ruby
|
|
apache_module "php5" do
|
|
filename "libphp5.so"
|
|
end
|
|
```
|
|
|
|
Disable a module:
|
|
|
|
```ruby
|
|
apache_module "disabled_module" do
|
|
enable false
|
|
end
|
|
```
|
|
|
|
See the recipes directory for many more examples of `apache_module`.
|
|
|
|
apache\_mod (internal)
|
|
----------------------
|
|
|
|
Sets up configuration file for an Apache module from a template. The
|
|
template should be in the same cookbook where the definition is used.
|
|
This is used by the `apache_module` definition and is not often used
|
|
directly.
|
|
|
|
This will use a template resource to write the module's configuration
|
|
file in the `mods-available` under the Apache configuration directory
|
|
(`node['apache']['dir']`). This is a platform-dependent location. See
|
|
__apache\_module__.
|
|
|
|
### Parameters:
|
|
|
|
* `name` - Name of the template. When used from the `apache_module`,
|
|
it will use the same name as the module.
|
|
|
|
### Examples:
|
|
|
|
Create `#{node['apache']['dir']}/mods-available/alias.conf`.
|
|
|
|
```ruby
|
|
apache_mod "alias"
|
|
```
|
|
|
|
apache\_site
|
|
------------
|
|
|
|
Enable or disable a VirtualHost in
|
|
`#{node['apache']['dir']}/sites-available` by calling a2ensite or
|
|
a2dissite to manage the symbolic link in
|
|
`#{node['apache']['dir']}/sites-enabled`.
|
|
|
|
The template for the site must be managed as a separate resource. To
|
|
combine the template with enabling a site, see `web_app`.
|
|
|
|
### Parameters:
|
|
|
|
* `name` - Name of the site.
|
|
* `enable` - Default true, which uses `a2ensite` to enable the site. If false, the site will be disabled with `a2dissite`.
|
|
|
|
web\_app
|
|
--------
|
|
|
|
Manage a template resource for a VirtualHost site, and enable it with
|
|
`apache_site`. This is commonly done for managing web applications
|
|
such as Ruby on Rails, PHP or Django, and the default behavior
|
|
reflects that. However it is flexible.
|
|
|
|
This definition includes some recipes to make sure the system is
|
|
configured to have Apache and some sane default modules:
|
|
|
|
* `apache2`
|
|
* `apache2::mod_rewrite`
|
|
* `apache2::mod_deflate`
|
|
* `apache2::mod_headers`
|
|
|
|
It will then configure the template (see __Parameters__ and
|
|
__Examples__ below), and enable or disable the site per the `enable`
|
|
parameter.
|
|
|
|
### Parameters:
|
|
|
|
Current parameters used by the definition:
|
|
|
|
* `name` - The name of the site. The template will be written to
|
|
`#{node['apache']['dir']}/sites-available/#{params['name']}.conf`
|
|
* `cookbook` - Optional. Cookbook where the source template is. If
|
|
this is not defined, Chef will use the named template in the
|
|
cookbook where the definition is used.
|
|
* `template` - Default `web_app.conf.erb`, source template file.
|
|
* `enable` - Default true. Passed to the `apache_site` definition.
|
|
|
|
Additional parameters can be defined when the definition is called in
|
|
a recipe, see __Examples__.
|
|
|
|
### Examples:
|
|
|
|
The recommended way to use the `web_app` definition is in a application specific cookbook named "my_app".
|
|
The following example would look for a template named 'web_app.conf.erb' in your cookbook containing
|
|
the apache httpd directives defining the `VirtualHost` that would serve up "my_app".
|
|
|
|
```ruby
|
|
web_app "my_app" do
|
|
template 'web_app.conf.erb'
|
|
server_name node['my_app']['hostname']
|
|
end
|
|
```
|
|
|
|
All parameters are passed into the template. You can use whatever you
|
|
like. The apache2 cookbook comes with a `web_app.conf.erb` template as
|
|
an example. The following parameters are used in the template:
|
|
|
|
* `server_name` - ServerName directive.
|
|
* `server_aliases` - ServerAlias directive. Must be an array of aliases.
|
|
* `docroot` - DocumentRoot directive.
|
|
* `application_name` - Used in RewriteLog directive. Will be set to the `name` parameter.
|
|
* `directory_index` - Allow overriding the default DirectoryIndex setting, optional
|
|
* `directory_options` - Override Options on the docroot, for example to add parameters like Includes or Indexes, optional.
|
|
* `allow_override` - Modify the AllowOverride directive on the docroot to support apps that need .htaccess to modify configuration or require authentication.
|
|
|
|
To use the default web_app, for example:
|
|
|
|
```ruby
|
|
web_app "my_site" do
|
|
server_name node['hostname']
|
|
server_aliases [node['fqdn'], "my-site.example.com"]
|
|
docroot "/srv/www/my_site"
|
|
cookbook 'apache2'
|
|
end
|
|
```
|
|
|
|
The parameters specified will be used as:
|
|
|
|
* `@params[:server_name]`
|
|
* `@params[:server_aliases]`
|
|
* `@params[:docroot]`
|
|
|
|
In the template. When you write your own, the `@` is significant.
