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
This cookbook ships with templates of these scripts for non Debian/Ubuntu platforms. The scripts are used in the Definitions below.
- Ohai: 0.6.12+
- Chef: 0.10.10+
As of v1.2.0, this cookbook makes use of node['platform_family']
to
simplify platform selection logic. This attribute was introduced in
Ohai v0.6.12. The recipe methods were introduced in Chef v0.10.10. If
you must run an older version of Chef or Ohai, use version 1.1.16 of
this cookbook.
This cookbook doesn't have direct dependencies on other cookbooks, as none are needed for the default recipe or the general use cases.
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- apt cache outdated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
- IPtables
- Compile tools
- 3rd party repositories
On Ubuntu/Debian, use Opscode's 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.
On RHEL, SELinux is enabled by default. The 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.
The easiest but certainly not ideal way to deal with IPtables is
to flush all rules. Opscode does provide an iptables
cookbook but is
migrating from the approach used there to a more robust solution
utilizing a general "firewall" LWRP that would have an "iptables"
provider. Alternately, you can use ufw, with Opscode's ufw
and
firewall
cookbooks to set up 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 Opscode's 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
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.
The apache2::god_monitor
recipe uses a definition from the god
cookbook. Include recipe[god]
in the node's expanded run list to
ensure that the cookbook is available to the node, and to set up god
.
The following platforms and versions are tested and supported using Opscode's test-kitchen.
- Ubuntu 10.04, 12.04
- CentOS 5.8, 6.3
The following platform families are supported in the code, and are assumed to work based on the successful testing on Ubuntu and CentOS.
- Debian
- Red Hat (rhel)
- Fedora
- Amazon Linux
The following platforms are also supported in the code, have been tested manually but are not tested under test-kitchen.
- SUSE/OpenSUSE
- ArchLinux
- FreeBSD
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. Opscode's yum
cookbook contains a recipe to add the
EPEL repository. See Examples for more information.
The apache2::mod_php5
recipe depends on the freebsd
cookbook,
which it uses to set the correct options for compiling the php5
port
from sources. You need to ensure the freebsd
is in the expanded run
list, or this recipe will fail. We don't set an explicit dependency
because we feel the freebsd
cookbook is something users would want
on their nodes, and due to the generality of this cookbook we don't
want additional specific dependencies.
This cookbook in the source repository contains minitest and cucumber tests. This is an initial proof of concept that will be fleshed out with more supporting infrastructure at a future time.
Please see the CONTRIBUTING file for information on how to add tests for your contributions.
This cookbook uses many attributes, broken up into a few different kinds.
In order to support the broadest number of platforms, several attributes are determined based on the node's platform. See the attributes/default.rb file for default values in the case statement at the top of the file.
node['apache']['dir']
- Location for the Apache configurationnode['apache']['log_dir']
- Location for Apache logsnode['apache']['error_log']
- Location for the default error lognode['apache']['access_log']
- Location for the default access lognode['apache']['user']
- User Apache runs asnode['apache']['group']
- Group Apache runs asnode['apache']['binary']
- Apache httpd server daemonnode['apache']['icondir']
- Location for iconsnode['apache']['cache_dir']
- Location for cached files used by Apache itself or recipesnode['apache']['pid_file']
- Location of the PID file for Apache httpdnode['apache']['lib_dir']
- Location for shared librariesnode['apache']['default_site_enabled']
- Default site enabled. Default is false.node['apache']['ext_status']
- if true, enables ExtendedStatus formod_status
These are general settings used in recipes and templates. Default values are noted.
node['apache']['listen_addresses']
- Addresses that httpd should listen on. Default is any ("*") and a list is expected (e.g.["127.0.0.1"]
).node['apache']['listen_ports']
- Ports that httpd should listen on. Default is port 80 and a list is expected (e.g.["8080", "4343"]
).node['apache']['contact']
- Value for ServerAdmin directive. Default "ops@example.com".node['apache']['timeout']
- Value for the Timeout directive. Default is 300.node['apache']['keepalive']
- Value for the KeepAlive directive. Default is On.node['apache']['keepaliverequests']
- Value for MaxKeepAliveRequests. Default is 100.node['apache']['keepalivetimeout']
- Value for the KeepAliveTimeout directive. Default is 5.node['apache']['default_modules']
- Array of module names. Can take "mod_FOO" or "FOO" as names, where FOO is the apache module, e.g. "mod_status
" or "status
".
The modules listed in default_modules
will be included as recipes in recipe[apache::default]
.
Prefork attributes are used for tuning the Apache HTTPD prefork MPM configuration.
node['apache']['prefork']['startservers']
- initial number of server processes to start. Default is 16.node['apache']['prefork']['minspareservers']
- minimum number of spare server processes. Default 16.node['apache']['prefork']['maxspareservers']
- maximum number of spare server processes. Default 32.node['apache']['prefork']['serverlimit']
- upper limit on configurable server processes. Default 400.node['apache']['prefork']['maxclients']
- Maximum number of simultaneous connections.node['apache']['prefork']['maxrequestsperchild']
- Maximum number of request a child process will handle. Default 10000.
Worker attributes are used for tuning the Apache HTTPD worker MPM configuration.
node['apache']['worker']['startservers']
- Initial number of server processes to start. Default 4node['apache']['worker']['serverlimit']
- upper limit on configurable server processes. Default 16.node['apache']['worker']['maxclients']
- Maximum number of simultaneous connections. Default 1024.node['apache']['worker']['minsparethreads']
- Minimum number of spare worker threads. Default 64node['apache']['worker']['maxsparethreads']
- Maximum number of spare worker threads. Default 192.node['apache']['worker']['maxrequestsperchild']
- Maximum number of requests a child process will handle.
The following attributes are in the attributes/mod_auth_openid.rb
file. Like all Chef attributes files, they are loaded as well, but
they're logistically unrelated to the others, being specific to the
mod_auth_openid
recipe.
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_openidnode['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 directiveAuthOpenIDDBLocation
, stored in thecache_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.
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.
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_alias
,
mod_basic
, mod_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
.
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.
Logrotate adds a logrotate entry for your apache2 logs. This recipe
requires the logrotate
cookbook; ensure that recipe[logrotate]
is
in the node's expanded run list.
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
Changed via COOK-915
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
.
AuthType OpenID
instead ofAuthOpenIDEnabled On
.require user
instead ofAuthOpenIDUserProgram
.- A bug(?) in
mod_auth_openid
causes it to segfault when attempting to update the database file if the containing directory is not writable by the HTTPD process owner (e.g., www-data), even if the file is writable. In order to not interfere with other settings from the default recipe in this cookbook, the db file is moved.
Install the fastcgi package and enable the module.
Only work on Debian/Ubuntu
Installs the fcgi package and enables the module. Requires EPEL on RHEL family.
On RHEL family, this recipe will delete the fcgid.conf and on version 6+, create the /var/run/httpd/mod_fcgid` directory, which prevents the emergency error:
[emerg] (2)No such file or directory: mod_fcgid: Can't create shared memory for size XX bytes
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.
Besides installing and enabling mod_ssl
, this recipe will append
port 443 to the node['apache']['listen_ports']
attribute array and
update the ports.conf.
Sets up a god
monitor for Apache. External requirements are the
god
and runit
cookbooks from Opscode. When using this recipe,
include recipe[god]
in the node's expanded run list to ensure the
client downloads it; god
depends on runit so that will also be
downloaded.
Note This recipe is not tested under test-kitchen yet and is pending fix in COOK-744.
The cookbook provides a few definitions. At some point in the future these definitions may be refactored into lightweight resources and providers as suggested by foodcritic rule FC015.
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.
name
- Name of the template. When used from theapache_module
, it will use the same name as the module.
Create #{node['apache']['dir']}/mods-available/alias.conf
.
apache_conf "alias"
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.
name
- Name of the module enabled or disabled with thea2enmod
ora2dismod
scripts.identifier
- String to identify the module for theLoadModule
directive. Not typically needed, defaults to#{name}_module
enable
- Default true, which usesa2enmod
to enable the module. If false, the module will be disabled witha2dismod
.conf
- Default false. Set to true if the module has a config file, which will useapache_conf
for the file.filename
- specify the full name of the file, e.g.
Enable the ssl module, which also has a configuration template in templates/default/mods/ssl.conf.erb
.
apache_module "ssl" do
conf true
end
Enable the php5 module, which has a different filename than the module default:
apache_module "php5" do
filename "libphp5.so"
end
Disable a module:
apache_module "disabled_module" do
enable false
end
See the recipes directory for many more examples of apache_module
.
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
.
name
- Name of the site.enable
- Default true, which usesa2ensite
to enable the site. If false, the site will be disabled witha2dissite
.
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.
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
- Defaultweb_app.conf.erb
, source template file.enable
- Default true. Passed to theapache_site
definition.
Additional parameters can be defined when the definition is called in a recipe, see Examples.
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 thename
parameter.directory_index
- Allow overriding the default DirectoryIndex setting, optionaldirectory_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:
web_app "my_site" do
server_name node['hostname']
server_aliases [node['fqdn'], "my-site.example.com"]
docroot "/srv/www/my_site"
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.
For more information about Definitions and parameters, see the Chef Wiki
Using this cookbook is relatively straightforward. 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:
% 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_ports" => ["80", "443"]
}
)
For examples of using the definitions in your own recipes, see their respective sections above.
