This still needs a great deal of work. In particular, many of the ./configure command line options are not documented because I was not able to get them to work in my testing. However, there is enough documented here to get most people going.

    Use the --prefix=PREFIX and --exec-prefix=EPREFIX options to -configure Apache to use a particular installation prefix. The default -is PREFIX=/usr/local/apache and EPREFIX=PREFIX.

    Use the --bindir=DIR, --sbindir=DIR, --libexecdir=DIR, ---mandir=DIR, --sysconfdir=DIR, --datadir=DIR, --iconsdir=DIR, ---htdocsdir=DIR, --cgidir=DIR, --includedir=DIR, --localstatedir=DIR, ---runtimedir=DIR, --logfiledir=DIR and --proxycachedir=DIR option to -change the paths for particular subdirectories of the installation -tree.

    Note: To reduce the pollution of shared installation locations -(like /usr/local/ or /etc) with Apache files to a minimum the string -``/apache'' is automatically appended to 'libexecdir', 'sysconfdir', -'datadir', 'localstatedir' and 'includedir' if (and only if) the -following points apply for each path individually:

    -
      -
    1. the path doesn't already contain the word ``apache''
      2. -
    2. the path was not directly customized by the user
      3. -
    - -

    Keep in mind that per default these paths are derived from 'prefix' -and 'exec-prefix', so usually its only a matter whether these paths -contain ``apache'' or not. Although the defaults were defined with -experience in mind you always should make sure the paths fit your -situation by checking the finally chosen paths via the --layout -option.

    - -

    Use the --with-layout=[F:]ID option to select a particular -installation path base-layout. You always _HAVE_ to select a -base-layout. There are currently two layouts pre-defined in the file -config.layout: `Apache' for the classical Apache path layout and `GNU' -for a path layout conforming to the GNU `standards' document. When you -want to use your own custom layout FOO, either add a corresponding -"<Layout FOO>...</Layout>" section to config.layout and use ---with-layout=FOO or place it into your own file, say config.mypaths, -and use --with-layout=config.mypaths:FOO.

    - -

    Use the --show-layout option to check the final installation path -layout while fiddling with the options above.

    - -

    Use the --enable-NAME=(shared) and --disable-NAME options to enable -or disable a particular already distributed module from the Apache -package.

    - -

    Use the --with-mpm=NAME option to determine which MPM should be -built for your server.

    +is to run ./configure --help. What follows is a brief description +of most of the arguments and environment variables.

    + +

    Environment Variables

    + +

    The autoconf build process uses several environment variables to +configure the build environment. In general, these variables change +the method used to build Apache, but not the eventual features of the +server. These variables can be placed in the environment before +invoking configure, but it is usually easier to specify +them on the configure command line as demonstrated +in the example above.

    + +
    + +
    CC=...
    +
    The name of the C compiler command.
    + +
    CPPFLAGS=...
    Miscellaneous C preprocessor +and compiler options.
    + +
    CFLAGS=...
    +
    Debugging and optimization options for the C compiler.
    + +
    LDFLAGS=...
    +
    Miscellaneous options to be passed to the linker.
    + +
    LIBS=...
    +
    Library location information ("-L" and "-l" options) +to pass to the linker.
    + +
    INCLUDES=...
    +
    Header file search directories ("-Idir").
    + +
    TARGET=... [Default: apache]
    +
    Name of the executable which will be built.
    + +
    NOTEST_CPPFLAGS=...
    +
    NOTEST_CFLAGS=...
    +
    NOTEST_LDFLAGS=...
    +
    NOTEST_LIBS=...
    +
    These variables share the same function as their non-NOTEST namesakes. +However, the variables are applied to the build process only after +autoconf has performed its feature testing. This allows the inclusion of +flags which will cause problems during feature testing, but must be used +for the final compilation.
    + +
    SHLIB_PATH=...
    +
    Options which specify shared library paths for the compiler and +linker.
    + +
    + +

    autoconf Output Options

    + +
    + +
    --help
    +
    Prints the usage message including all available options, but +does not actually configure anything.
    + +
    --quiet
    +
    Prevents the printing of the usual "checking..." messages.
    + +
    --verbose
    +
    Prints much more information during the configuration process, +including the names of all the files examined.
    + +
    + +

    Pathnames

    + +

    There are currently two ways to configure the pathnames under +which Apache will install its files. First, you can specify +a directory and have Apache install itself under that directory +in its default locations.

    + +
    +
    --prefix=PREFIX [Default: +/usr/local/apache2]
    +
    Specifies the directory under which the Apache files will be +installed.
    +
    + +

    It is possible to specify that architecture-dependent files should +be placed under a different directory.

    + +
    +
    --exec-prefix=EPREFIX [Default: +PREFIX]
    +
    Specifies the directory under which architecture-dependent files +will be placed.
    +
    + +

    The second, and more flexible way to configure the install path +locations for Apache is using the config.layout file. +Using this method, it is possible to separately specify the location +for each type of file within the Apache installation. The +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.

    + +
    + +
    --enable-layout=LAYOUT
    +
    Use the named layout in the config.layout file +to specify the installation paths.
    + +
    + +

    Presently it is not possible to mix the +--enable-layout and --prefix options. Nor +is it possible to individually specify detailed pathnames on the +configure command line. If you want just a basic +install, you can simply use the --prefix option on its +own. If you want to customize your install, you should edit the +config.layout file and use the +--enable-layout option.

    + +

    Modules

    + +

    Apache is a modular server. Only the most basic functionality is +included in the core server. Extended features are available in +various modules. During the configuration process, you must select +which modules to compile for use with your server. You can view a list of modules included in the +documentation. Those modules with a status +of "Base" are included by default and must be specifically disabled if +you do not want them. Modules with any other status must be +specifically enabled if you wish to use them.

    + +

    There are two ways for a module to be compiled and used with +Apache. Modules may be statically compiled, which means that +they are permanently included in the Apache binary. Alternatively, if +your operating system supports Dynamic Shared Objects (DSOs) and +autoconf can detect that support, then modules may be dynamically +compiled. DSO modules are stored separately from the Apache +binary, and may be included or excluded from the server using the +run-time configuration directives provided by mod_so. The mod_so is automatically +included in the server if any dynamic modules are included in the +compilation. If you would like to make your server capable of loading +DSOs without actually compiling any dynamic modules, you can +explicitly --enable-so.

    + +
    + +
    --enable-MODULE[=shared]
    Compile +and include the module MODULE. The identifier +MODULE is the Module Identifier from the module documentation without the +"_module" string. To compile the module dynamically as a DSO, add the +option =shared.
    + +
    --disable-MODULE
    +
    Remove the module MODULE which would otherwise be +compiled and included.
    + +
    + +

    In addition to the standard set of modules, Apache 2.0 also +includes a choice of Multi-Processing Modules +(MPMs). One, and only one MPM must be included in the compilation +process. The default MPMs for each platform are listed on the MPM documentation page, but can be overridden +on the configure command line. + +

    + +
    --with-mpm=NAME
    +
    Choose the mpm NAME. + +
    + +

    Suexec

    + +

    Apache includes a support program called suexec which can be used to isolate user CGI +programs. However, if suexec is improperly configured, it can cause +serious security problems. Therefore, you should carefully read and +consider the suexec documentation before +implementing this feature.

    Preparing the system

    - -

    Proper operation of a public HTTP server requires at least the -following:

    - -
      - -
    1. A correctly working TCP/IP layer, since HTTP is implemented on top -of TCP/IP. Although modern Unix platforms have good networking layers, -always make sure you have all official vendor patches referring to the -network layer applied.
      2. - -
    2. Accurate time keeping, since elements of the HTTP protocol are -expressed as the time of day. So, it's time to investigate setting -some time synchronization facility on your system. Usually the ntpdate -or xntpd programs are used for this purpose which are based on the -Network Time Protocol (NTP). See the Usenet newsgroup -comp.protocols.time.ntp and the NTP homepage at -http://www.eecis.udel.edu/~ntp/ for more details about NTP software -and public time servers.

    • Dynamic Shared Object (DSO) support [OPTIONAL]

      To provide -maximum flexibility Apache now is able to load modules under runtime -via the DSO mechanism by using the pragmatic -apr_dso_open()/apr_dso_sym() calls. These calls are not available -under all operating systems therefore you cannot use the DSO mechanism -on all platforms. Apache relies on autoconf to detect the ability to -use DSOs, and libtool to determine how to build DSOs. If your platform -is supported by libtool, and we can find DSO system calls, then DSOs -should work out-of-the-box.

      - -If your system is not on these lists but has the dlopen-style -interface, you either have to provide the appropriate compiler and -linker flags manually or at least make sure a Perl 5 interpreter is -installed from which Apache can guess the options.

    • Disk Space

      Make sure you have at least 50 MB of temporary +free disk space available. After installation Apache occupies +approximately 10 MB of disk space. The actual disk space requirements +will vary considerably based on your chosen configuration options and +any third-party modules.

    Download

    If you are building from a copy of the CVS repository, rather than -a release distribution, then you will need these additional tools:

    +

    Apache can be downloaded from the Apache Software Foundation +download site or from a nearby mirror.

    -
      - -
    • Libtool 1.3.3

      Make sure that you have libtool 1.3.3 or -later installed before trying to configure and build Apache 2.0. -Libtool can be downloaded from the Free Software Foundation (FSF), at -http://www.gnu.org/order/ftp.html.

      • +

      Version numbers that end in alpha indicate early +pre-test versions which may or may not work. Version numbers ending +in beta indicate more reliable releases that still +require further testing or bug fixing. If you wish to dowload the +best available production release of the Apache HTTP Server, you +should choose the latest version with neither alpha nor +beta in its filename.

      -
    • Autoconf 2.13

      Make sure that you have autoconf 2.13 or -later installed before trying to configure and build Apache 2.0. -Autoconf can be downloaded from the Free Software Foundation (FSF), at -http://www.gnu.org/order/ftp.html.

      After downloading, especially if a mirror site is used, it is +important to verify that you have a complete and unmodified version +of the Apache HTTP Server. This can be accomplished by testing the +downloaded tarball against the PGP signature, which should always be +obtained from the main +Apache website. The signature file has a filename identical to +the source tarball with the addition of .asc.

    This script ensures that all required programs are installed on the -currently machine, and creates the ./configure script. If you are -using a package downloaded from apache.org then this step is not -necessary.

    - -

    Use the --prefix=PREFIX and --exec-prefix=EPREFIX options to -configure Apache to use a particular installation prefix. The default -is PREFIX=/usr/local/apache and EPREFIX=PREFIX.

    - -

    Use the --bindir=DIR, --sbindir=DIR, --libexecdir=DIR, ---mandir=DIR, --sysconfdir=DIR, --datadir=DIR, --iconsdir=DIR, ---htdocsdir=DIR, --cgidir=DIR, --includedir=DIR, --localstatedir=DIR, ---runtimedir=DIR, --logfiledir=DIR and --proxycachedir=DIR option to -change the paths for particular subdirectories of the installation -tree.

    - -

    Note: To reduce the pollution of shared installation locations -(like /usr/local/ or /etc) with Apache files to a minimum the string -``/apache'' is automatically appended to 'libexecdir', 'sysconfdir', -'datadir', 'localstatedir' and 'includedir' if (and only if) the -following points apply for each path individually:

    -
      -
    1. the path doesn't already contain the word ``apache''
      2. -
    2. the path was not directly customized by the user
      3. -
    - -

    Keep in mind that per default these paths are derived from 'prefix' -and 'exec-prefix', so usually its only a matter whether these paths -contain ``apache'' or not. Although the defaults were defined with -experience in mind you always should make sure the paths fit your -situation by checking the finally chosen paths via the --layout -option.

    - -

    Use the --with-layout=[F:]ID option to select a particular -installation path base-layout. You always _HAVE_ to select a -base-layout. There are currently two layouts pre-defined in the file -config.layout: `Apache' for the classical Apache path layout and `GNU' -for a path layout conforming to the GNU `standards' document. When you -want to use your own custom layout FOO, either add a corresponding -"<Layout FOO>...</Layout>" section to config.layout and use ---with-layout=FOO or place it into your own file, say config.mypaths, -and use --with-layout=config.mypaths:FOO.

    - -

    Use the --show-layout option to check the final installation path -layout while fiddling with the options above.

    - -

    Use the --enable-NAME=(shared) and --disable-NAME options to enable -or disable a particular already distributed module from the Apache -package.

    - -

    Use the --with-mpm=NAME option to determine which MPM should be -built for your server.

    +is to run ./configure --help. What follows is a brief description +of most of the arguments and environment variables.

    + +

    Environment Variables

    + +

    The autoconf build process uses several environment variables to +configure the build environment. In general, these variables change +the method used to build Apache, but not the eventual features of the +server. These variables can be placed in the environment before +invoking configure, but it is usually easier to specify +them on the configure command line as demonstrated +in the example above.

    + +
    + +
    CC=...
    +
    The name of the C compiler command.
    + +
    CPPFLAGS=...
    Miscellaneous C preprocessor +and compiler options.
    + +
    CFLAGS=...
    +
    Debugging and optimization options for the C compiler.
    + +
    LDFLAGS=...
    +
    Miscellaneous options to be passed to the linker.
    + +
    LIBS=...
    +
    Library location information ("-L" and "-l" options) +to pass to the linker.
    + +
    INCLUDES=...
    +
    Header file search directories ("-Idir").
    + +
    TARGET=... [Default: apache]
    +
    Name of the executable which will be built.
    + +
    NOTEST_CPPFLAGS=...
    +
    NOTEST_CFLAGS=...
    +
    NOTEST_LDFLAGS=...
    +
    NOTEST_LIBS=...
    +
    These variables share the same function as their non-NOTEST namesakes. +However, the variables are applied to the build process only after +autoconf has performed its feature testing. This allows the inclusion of +flags which will cause problems during feature testing, but must be used +for the final compilation.
    + +
    SHLIB_PATH=...
    +
    Options which specify shared library paths for the compiler and +linker.
    + +
    + +

    autoconf Output Options

    + +
    + +
    --help
    +
    Prints the usage message including all available options, but +does not actually configure anything.
    + +
    --quiet
    +
    Prevents the printing of the usual "checking..." messages.
    + +
    --verbose
    +
    Prints much more information during the configuration process, +including the names of all the files examined.
    + +
    + +

    Pathnames

    + +

    There are currently two ways to configure the pathnames under +which Apache will install its files. First, you can specify +a directory and have Apache install itself under that directory +in its default locations.

    + +
    +
    --prefix=PREFIX [Default: +/usr/local/apache2]
    +
    Specifies the directory under which the Apache files will be +installed.
    +
    + +

    It is possible to specify that architecture-dependent files should +be placed under a different directory.

    + +
    +
    --exec-prefix=EPREFIX [Default: +PREFIX]
    +
    Specifies the directory under which architecture-dependent files +will be placed.
    +
    + +

    The second, and more flexible way to configure the install path +locations for Apache is using the config.layout file. +Using this method, it is possible to separately specify the location +for each type of file within the Apache installation. The +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.

    + +
    + +
    --enable-layout=LAYOUT
    +
    Use the named layout in the config.layout file +to specify the installation paths.
    + +
    + +

    Presently it is not possible to mix the +--enable-layout and --prefix options. Nor +is it possible to individually specify detailed pathnames on the +configure command line. If you want just a basic +install, you can simply use the --prefix option on its +own. If you want to customize your install, you should edit the +config.layout file and use the +--enable-layout option.

    + +

    Modules

    + +

    Apache is a modular server. Only the most basic functionality is +included in the core server. Extended features are available in +various modules. During the configuration process, you must select +which modules to compile for use with your server. You can view a list of modules included in the +documentation. Those modules with a status +of "Base" are included by default and must be specifically disabled if +you do not want them. Modules with any other status must be +specifically enabled if you wish to use them.

    + +

    There are two ways for a module to be compiled and used with +Apache. Modules may be statically compiled, which means that +they are permanently included in the Apache binary. Alternatively, if +your operating system supports Dynamic Shared Objects (DSOs) and +autoconf can detect that support, then modules may be dynamically +compiled. DSO modules are stored separately from the Apache +binary, and may be included or excluded from the server using the +run-time configuration directives provided by mod_so. The mod_so is automatically +included in the server if any dynamic modules are included in the +compilation. If you would like to make your server capable of loading +DSOs without actually compiling any dynamic modules, you can +explicitly --enable-so.

    + +
    + +
    --enable-MODULE[=shared]
    Compile +and include the module MODULE. The identifier +MODULE is the Module Identifier from the module documentation without the +"_module" string. To compile the module dynamically as a DSO, add the +option =shared.
    + +
    --disable-MODULE
    +
    Remove the module MODULE which would otherwise be +compiled and included.
    + +
    + +

    In addition to the standard set of modules, Apache 2.0 also +includes a choice of Multi-Processing Modules +(MPMs). One, and only one MPM must be included in the compilation +process. The default MPMs for each platform are listed on the MPM documentation page, but can be overridden +on the configure command line. + +

    + +
    --with-mpm=NAME
    +
    Choose the mpm NAME. + +
    + +

    Suexec

    + +

    Apache includes a support program called suexec which can be used to isolate user CGI +programs. However, if suexec is improperly configured, it can cause +serious security problems. Therefore, you should carefully read and +consider the suexec documentation before +implementing this feature.

    Preparing the system

    Proper operation of a public HTTP server requires at least the -following:

    - -
      - -
    1. A correctly working TCP/IP layer, since HTTP is implemented on top -of TCP/IP. Although modern Unix platforms have good networking layers, -always make sure you have all official vendor patches referring to the -network layer applied.
      2. - -
    2. Accurate time keeping, since elements of the HTTP protocol are -expressed as the time of day. So, it's time to investigate setting -some time synchronization facility on your system. Usually the ntpdate -or xntpd programs are used for this purpose which are based on the -Network Time Protocol (NTP). See the Usenet newsgroup -comp.protocols.time.ntp and the NTP homepage at -http://www.eecis.udel.edu/~ntp/ for more details about NTP software -and public time servers.
