Apache HTTP Server Version 2.2
The configure
script configures the source tree
for compiling and installing the Apache HTTP Server on your
particular platform. Various options allow the compilation of a
server corresponding to your personal requirements.
This script, included in the root directory of the source distribution, is for compilation on Unix and Unix-like systems only. For other platforms, see the platform documentation.
You should call the configure
script from within the
root directory of the distribution.
./configure [OPTION]...
[VAR=VALUE]...
To assign environment variables (e.g. CC
,
CFLAGS
...), specify them as
VAR=VALUE
. See below
for descriptions of some of the useful variables.
The following options influence the behavior of
configure
itself.
-C
--config-cache
--cache-file=config.cache
--cache-file=FILE
-h
--help [short|recursive]
short
only
options specific to this package will displayed. The argument
recursive
displays the short help of all the included
packages.-n
--no-create
configure
script is run normally but does
not create output files. This is useful to check the test results
before generating makefiles for compilation.-q
--quiet
checking ...
messages during the
configure process.--srcdir=DIR
configure
is located, or
the parent directory.--silent
--quiet
These options define the installation directory. The installation tree depends on the selected layout.
--prefix=PREFIX
/usr/local/apache2
.--exec-prefix=EPREFIX
By default, make install
will install all the files in
/usr/local/apache2/bin
, /usr/local/apache2/lib
etc. You can specify an installation prefix other than
/usr/local/apache2
using --prefix
,
for instance --prefix=$HOME
.
--enable-layout=LAYOUT
config.layout
file contains several example configurations, and you can also create
your own custom configuration following the examples. The different
layouts in this file are grouped into <Layout
FOO>...</Layout>
sections and referred to by name as
in FOO
. The default layout is Apache
.For better control of the installation directories, use the options
below. Please note that the directory defaults are set by
autoconf
and are overwritten by the corresponding layout
setting.
--bindir=DIR
htpasswd
,
dbmmanage
, etc. which are useful for site
administrators. By default DIR is set to
EPREFIX/bin
.--datadir=DIR
datadir
is set to
PREFIX/share
. This option is offered by
autoconf
and currently unused.--includedir=DIR
includedir
is set to
EPREFIX/include
.--infodir=DIR
infodir
is set to
PREFIX/info
. This option is currently
unused.--libdir=DIR
libdir
is set to
EPREFIX/lib
.--libexecdir=DIR
libexecdir
is set to
EPREFIX/modules
.--localstatedir=DIR
localstatedir
is set to
PREFIX/var
. This option is offered by
autoconf
and currently unused.--mandir=DIR
mandir
is set to
EPREFIX/man
.--oldincludedir=DIR
oldincludedir
is set to
/usr/include
. This option is offered by
autoconf
and currently unused.--sbindir=DIR
httpd
,
apachectl
, suexec
, etc. which
are neccessary to run the Apache HTTP Server. By default
sbindir
is set to
EPREFIX/sbin
.--sharedstatedir=DIR
sharedstatedir
is set to
PREFIX/com
. This option is offered by
autoconf
and currently unused.--sysconfdir=DIR
httpd.conf
, mime.types
, etc. in
DIR. By default sysconfdir
is set to
PREFIX/conf
.These options are used to cross-compile the Apache HTTP Server to run on another system. In normal cases, when building and running the server on the same system, these options are not used.
--build=BUILD
config.guess
.--host=HOST
--target=TARGET
autoconf
and not necessary for the Apache HTTP
Server.These options are used to fine tune the features your HTTP server will have.
Generally you can use the following syntax to enable or disable a feature:
--disable-FEATURE
--enable-FEATURE=no
.--enable-FEATURE[=ARG]
yes
.--enable-MODULE=shared
--enable-MODULE=static
configure
will not complain about
--enable-foo
even if foo doesn't
exist, so you need to type carefully.
Some modules are compiled by default and have to be disabled explicitly. Use the following options to remove discrete modules from the compilation process.
--disable-actions
mod_actions
.--disable-alias
mod_alias
.--disable-asis
mod_asis
.--disable-auth-basic
mod_auth_basic
. This module provides for HTTP Basic
Authentication, where the usernames and passwords are stored in
plain text files.--disable-autoindex
mod_autoindex
.--disable-cgi
mod_cgi
, which provides support for CGI scripts,
is enabled by default when using a non-threaded MPM. Use this
option to disable CGI support.--disable-cgid
worker
support for CGI scripts is provided by
mod_cgid
by default. To disable CGI support use
this option.--disable-charset-lite
mod_charset_lite
. This module will be installed by
default only on EBCDIC systems.--disable-dir
mod_dir
.--disable-env
mod_env
.--disable-http
http
module is a basic one, enabling the server to function as an
HTTP server. It is only useful to disable it if you want to use
another protocol module instead. Don't disable this
module unless you are really sure what you are doing.
--disable-imagemap
mod_imagemap
.--disable-include
mod_include
.--disable-log-config
mod_log_config
. You won't be able to log requests
to the server without this module.--disable-mime
mod_mime
associates the requested
filename's extensions with the file's behavior and content
(mime-type, language, character set and
encoding). Disabling this module is normally not recommended.--disable-negotiation
mod_negotiation
.--disable-setenvif
mod_setenvif
.--disable-status
mod_status
.--disable-userdir
mod_userdir
.Some modules are compiled by default and have to be enabled
explicitly or by using the keywords most
or
all
(see --enable-mods-shared
below for
further explanation) to be available. Therefore use the options
below.
--enable-authn-anon
mod_authn_anon
.--enable-authn-dbm
mod_authn_dbm
provides for HTTP Basic
Authentication, where the usernames and passwords are stored in DBM
type database files. Use this option to enable the module.--enable-authz-dbm
mod_authz_dbm
provides for HTTP Basic
Authorization, where the usernames and groups are stored in DBM
type database files. Use this option to enable the module.--enable-auth-digest
mod_auth_digest
. This module uses plain text files
to store the credentials.--enable-authnz-ldap
mod_authnz_ldap
.--enable-cache
mod_cache
. This experimental module may be
interesting for servers with high load or caching proxy servers. At
least one storage management module (e.g.
mod_disk_cache
or mod_mem_cache
)
is also necessary.--enable-cern-meta
mod_cern_meta
.--enable-charset-lite
mod_charset_lite
. This module will be installed by
default only on EBCDIC systems. On other systems, you have to enable
it.--enable-dav
mod_dav
. Support for filesystem resources is
provided by the separate module mod_dav_fs
. This
module is also automatically enabled with
--enable-dav
.mod_dav
can only be used together with the
http
protocol module.--enable-dav-fs
mod_dav_fs
. This module is a provider for the
mod_dav
module, so you should also use
--enable-dav
.--enable-dav-lock
mod_dav_lock
which provides generic DAV
locking support for backend modules. This module needs at least
mod_dav
to function, so you should also use
--enable-dav
.--enable-deflate

,
HTTP
and the balancer are provided by the separate
modules mod_proxy_ajp
,
mod_proxy_connect
, mod_proxy_ftp
,
mod_proxy_http
and
mod_proxy_balancer
.
These five modules are also automatically enabled with
--enable-proxy
.--enable-proxy-ajp
AJP13 (Apache JServ Protocol 1.3)
request handling, which is provided by mod_proxy_ajp
.
This module is an extension for the mod_proxy
module,
so you should also use --enable-proxy
.--enable-proxy-balancer
AJP13
,
FTP
and HTTP
protocols, which is provided by
mod_proxy_balancer
. This module is an extension for the
mod_proxy
module, so you should also use
--enable-proxy
.--enable-proxy-connect
CONNECT
request handling,
which is provided by mod_proxy_connect
. This module
is an extension for the mod_proxy
module, so you
should also use --enable-proxy
.--enable-proxy-ftp
FTP
requests, which is
provided by mod_proxy_ftp
. This module
is an extension for the mod_proxy
module, so you
should also use --enable-proxy
.--enable-proxy-http

provided by mod_proxy_http
. This module
is an extension for the mod_proxy
module, so you
should also use --enable-proxy
.--enable-rewrite

.--enable-optional-fn-import
mod_optional_fn_import
.--enable-optional-hook-export
mod_optional_hook_export
.--enable-optional-hook-import
mod_optional_hook_import
.To add the necessary Multi Processing Module and additional third-party modules use the following options:
--with-module=module-type:module-file[,
module-type:module-file]
Add one or more third-party modules to the list of statically linked
modules. The module source file module-file
will be searched in the modules/module-type
subdirectory of your Apache HTTP server source tree. If it is not found
there configure
is considering module-file to be
an absolute file path and tries to copy the source file into the
module-type subdirectory. If the subdirectory doesn't
exist it will be created and populated with a standard
Makefile.in
.
This option is useful to add small external modules consisting of one source file. For more complex modules you should read the vendor's documentation.
apxs
.--with-mpm=MPM
beos
,
mpmt_os2
,
prefork
, and
worker
.--enable-maintainer-mode
--enable-mods-shared=MODULE-LIST
Defines a list of modules to be enabled and build as dynamic
shared modules. This mean, these module have to be loaded
dynamically by using the LoadModule
directive.
MODULE-LIST is a space separated list of modulenames
enclosed by quotation marks. The module names are given without the
preceding mod_
. For example:
--enable-mods-shared='headers rewrite dav'
Additionally you can use the special keywords all
and
most
. For example,
--enable-mods-shared=most
will compile most modules and build them as DSO modules.
Caveat:
--enable-mods-shared=all
does not actually build all
modules. To build all modules then, one might use:
./configure \
--with-ldap \
--enable-mods-shared="all ssl ldap cache proxy authn_alias mem_cache file_cache authnz_ldap charset_lite dav_lock disk_cache"
--enable-modules=MODULE-LIST
--enable-mods-shared
,
but will link the given modules statically. This mean, these modules
will always be present while running httpd
. They need
not be loaded with LoadModule
.--enable-v4-mapped
--with-port=PORT
httpd
will listen.
This port number is used when generating the configuration file
httpd.conf
. The default is 80.--with-program-name
httpd
.These options are used to define optional packages.
Generally you can use the following syntax to define an optional package:
--with-PACKAGE[=ARG]
yes
.--without-PACKAGE
--with-PACKAGE=no
. This option is provided by
autoconf
but not very useful for the Apache HTTP
Server.--with-apr=DIR|FILE
configure
the path to the
apr-config
script. You may set the absolute path and name
or the directory to the installed APR. apr-config
must
exist within this directory or the subdirectory
bin
.--with-apr-util=DIR|FILE
configure
the path to the
apu-config
script. You may set the absolute path and name
or the directory to the installed APU. apu-config
must
exist within this directory or the subdirectory
bin
.--with-ssl=DIR
mod_ssl
has been enabled configure
searches for an installed OpenSSL. You can set the directory path
to the SSL/TLS toolkit instead.--with-z=DIR
configure
searches automatically for an installed
zlib
library if your source configuration requires one
(e.g., when mod_deflate
is enabled). You can set the
directory path to the compression library instead.Several features of the Apache HTTP Server, including
mod_authn_dbm
, mod_authz_dbm
, and
mod_rewrite
's DBM
RewriteMap
use simple
key/value databases for quick lookups of information. SDBM is included
in the APU, so this database is always available. If you would like to
use other database types, use the following options to enable
them:
--with-gdbm[=path]
configure
will
search for the include files and libraries of a GNU DBM
installation in the usual search paths. An explicit
path will cause configure
to look in
path/lib
and
path/include
for the relevant files.
Finally, the path may specify specific include and
library paths separated by a colon.--with-ndbm[=path]
--with-gdbm
, but searches for a New DBM
installation.--with-berkeley-db[=path]
--with-gdbm
, but searches for a Berkeley DB
installation.The DBM options are provided by the APU and passed through to its
configuration script. They are useless when using an already
installed APU defined by --with-apr-util
.
You may use more then one DBM implementation together with your HTTP server. The appropriated DBM type will be configured within the runtime configuration at each time.
--enable-static-support
--enable-suexec
suexec
, which allows you to set
uid and gid for spawned processes. Do not use this
option unless you understand all the security implications of
running a suid binary on your server. Further options
to configure suexec
are described below.It is possible to create a statically linked binary of a single support program by using the following options:
--enable-static-ab
ab
.--enable-static-checkgid
checkgid
.--enable-static-htdbm
htdbm
.--enable-static-htdigest
htdigest
.--enable-static-htpasswd
htpasswd
.--enable-static-logresolve
logresolve
.--enable-static-rotatelogs
rotatelogs
.suexec
configuration optionsThe following options are used to fine tune the behavior of suexec
. See Configuring and installing suEXEC
for further information.
--with-suexec-bin
suexec
binary.
Default is --sbindir
(see Fine tuning of installation
directories).--with-suexec-caller
suexec
.
It should be the same as the user under which
httpd
normally runs.--with-suexec-docroot
suexec
access is allowed for executables. Default value is
--datadir/htdocs
.--with-suexec-gidmin
suexec
. The default value is 100.--with-suexec-logfile
suexec
logfile.
By default the logfile is named suexec_log
and located in
--logfiledir
.--with-suexec-safepath
PATH
to
be set for processes started by suexec
. Default
value is /usr/local/bin:/usr/bin:/bin
.--with-suexec-userdir
suexec
access
is allowed. This setting is necessary when you want to use
suexec
together with user-specific directories (as
provided by mod_userdir
). The default is
public_html
.--with-suexec-uidmin
suexec
. The default value is 100.--with-suexec-umask
umask
for processes started by
suexec
. It defaults to your system settings.There are some useful environment variables to override the choices made by
configure
or to help it to find libraries and programs with
nonstandard names or locations.
