HTTPD Cookbook
The HTTPD Cookbook is a "Pure Library Cookbook" (Module Cookbook?)
that provides resource primitives for use in recipes. It is designed
to be an example to reference for creating highly re-usable cross
platform cookbooks.
This cookbook does its best to follow platform native idioms at all
times. This means things like logs, pid files, sockets, and service
managers work "as expected" by an administrator familiar with a given
platform.
Scope
This cookbook is concerned with
The Apache HTTP Server, particularly those
shipped with F/OSS Unix and Linux distributions. It does not address
other httpd server implementations like Lighttpd, Nginx, or IIS.
Requirements
- Chef 11 or higher
- Ruby 1.9 or higher (preferably from the Chef full-stack installer)
Resources
httpd_service
The httpd_service
does minimal configuration to get the service up
and running. Its parameters can select and tune the multi-processing
module, along with a small selection of server-wide configuration
options such as listen_ports and run_user.
All other configuration options are offloaded to the user, and should
be dropped off with the httpd_config
resource.
httpd_service
supports multiple Apache instances on a single
machine, enabling advanced Apache configuration in scenarios where
multiple servers need different loaded modules and global
configurations.
Examples
httpd_service 'default' do
action :create
end
httpd_service 'instance-1' do
listen_ports ['81', '82']
action :create
end
httpd_service 'an websites' do
instance_name 'bob'
servername 'www.computers.biz'
version '2.4'
mpm 'event'
threadlimit '4096'
listen_ports ['1234']
action :create
end
Parameters
Most of the parameters on the httpd_service
resource map to their
CamelCase equivalents found at
http://httpd.apache.org/docs/2.4/mod/directives.html
contact
- The email address rendered into the main configuration file as the ServerAdmin directive.
hostname_lookups
- Enables DNS lookups on client IP addresses. Can
be 'on' 'off' or 'double'. Defaults to 'off'.
instance
- A string name to identify the httpd_service
instance.
By convention, this will result in configuration, log, and support
directories being created and used in the form '/etc/instance-name',
'/var/log/instance-name', etc. If set to 'default', the platform
native defaults are used.
keepalive
- Enables HTTP persistent connections. Values can be true or false.
keepalivetimeout
- Amount of time the server will wait for
subsequent requests on a persistent connection.
listen_addresses
- IP addresses that the server listens
to. Defaults to ['0.0.0.0'].
listen_ports
- Ports that the server listens
to. Defaults to ['80', '443'].
log_level
- Controls the verbosity of the ErrorLog. Defaults to 'warn'.
maxclients
- Maximum number of connections that will be processed
simultaneously. Valid only with prefork and worker MPMs.
maxconnectionsperchild
- Limit on the number of connections that an individual child server
will handle during its life. Valid with Apache 2.4 prefork, worker and event MPMs.
maxkeepaliverequests
- Number of requests allowed on a persistent
connection. Defaults to 100.
maxrequestsperchild
- The Apache 2.2 version of maxconnectionsperchild. Still supported as of 2.4
maxrequestworkers
- Maximum number of connections that will be
processed simultaneously. Valid on prefork, worker, and event MPMs.
maxspareservers
- Maximum number of idle child server processes.
Valid only for prefork MPM.
maxsparethreads
- Maximum number of idle threads. Valid only for
worker and event MPMs.
minspareservers
- Minimum number of idle child server processes.
Valid only for preform MPM.
minsparethreads
- Minimum number of idle threads available to handle
request spikes. Valid only for worker and event MPMs.
mpm
- The Multi-Processing Module to use for the httpd_service
instance. Values can be 'prefork', 'worker', and 'event'. Defaults to
'worker' for Apache 2.2 and 'event' for Apache 2.4.
package_name
- Name of the server package to install on the machine
using the system package manager. Defaults to 'apache2' on Debian and
'httpd' on RHEL.
run_group
- System group to start the httpd_service
as. Defaults to
'www-data' on Debian and 'apache' on RHEL.
run_user
- System user to start the httpd_service
as. Defaults to
'www-data' on Debian and 'apache' on RHEL.
servername
- Hostname and port that the server uses to identify
itself. Syntax: [scheme://]fully-qualified-domain-name[:port].
Defaults to node['hostname'].
startservers
- Number of child server processes created at startup.
Valid for prefork, worker, and event MPMs. Default value differs from MPM to MPM.
threadlimit
- Sets the upper limit on the configurable number of
threads per child process. Valid on worker and event MPMs.
threadsperchild
- Number of threads created by each child process.
Valid on worker and event MPMs.
timeout
- Amount of time the server will wait for certain events
before failing a request. Defaults to '400'
version
- Apache software version to use. Available options are
'2.2', and '2.4', depending on platform. Defaults to latest available.
httpd_module
The httpd_module
resource is responsible ensuring that an Apache
module is installed on the system, as well as ensuring a load configuration
snippet is dropped off at the appropriate location.
Examples
httpd_module 'ssl' do
action :create
end
httpd_module 'el dap' do
module_name 'ldap'
action :create
end
httpd_module 'auth_pgsql' do
httpd_instance 'instance-2'
action :create
end
Parameters
filename
- The filename of the shared object to be rendered into the
load config snippet. This can usually be omitted, and defaults to a
generated value looked up in an internal map.
httpd_version
- The version of the httpd_service
this module is
meant to be installed for. Useful on platforms that support multiple
Apache versions. Defaults to the platform default.
instance
- The httpd_service
name to drop the load snippet off
for. Defaults to 'default'.
module_name
- The module name to install. Defaults to the
httpd_module
name.
package_name
- The package name the module is found in. By default,
this is looked up in an internal map.
httpd_config
The httpd_config
resource is a thin wrapper around the core Chef
template resource. Instead of a path parameter, httpd_config
uses
the instance parameter to calculate where the config is dropped off.
Examples
httpd_config 'mysite' do
source 'mysite.erb'
action :create
end
httpd_config 'computers dot biz ssl_config' do
config_name 'ssl-config'
httpd_instance 'computers_dot_biz'
source 'ssl_config.erb'
action :create
end
Parameters
config_name
- The name of the config on disk
cookbook
- The cookbook that the source template is found in. Defaults to the current cookbook.
httpd_version
- Used to calculate the configuration's disk path. Defaults to the platform's native Apache version.
instance
- The httpd_service
instance the config is meant for. Defaults to 'default'
source
- The ERB format template source used to render the file.
variables
- A hash of variables passed to the underlying template resource
