This document covers compilation and installation of Apache on Unix systems. For compiling and installation on other platforms, see
You may download the latest version of Apache either directly from the Download Page.
Like all good things, there are two ways to configure, compile, and install Apache. You can go for the 3-minute installation process using the APACI process described below; or, you can opt for the same mechanism used in previous versions of Apache, as described in the file 'src/INSTALL'. Each mechanism has its benefits and drawbacks - APACI is newer and a little more raw, but it gets you up and running the least amount of time, whereas the "Configuration.tmpl" mechanism may be more familiar and give you some more flexibility to the power user. We'd be very interested in your comments and feedback regarding each approach.
$ ./configure --prefix=PREFIX $ make $ make install $ PREFIX/bin/apachectl start
NOTE: PREFIX
is not the string "PREFIX". Instead
use the Unix filesystem path under which Apache should be installed. For
instance use "/usr/local/apache
" for PREFIX above.
The following requirements exist for building Apache:
To provide maximum flexibility Apache now is able to load modules under runtime via the DSO mechanism by using the pragmatic dlopen()/dlsym() system calls. These system calls are not available under all operating systems therefore you cannot use the DSO mechanism on all platforms. And Apache currently has only limited built-in knowledge on how to compile shared objects because this is heavily platform-dependent. The current state is this:
Linux | SunOS | UnixWare | Darwin/Mac OS |
FreeBSD | Solaris | AIX | OpenStep/Mach |
OpenBSD | IRIX | SCO | DYNIX/ptx |
NetBSD | HPUX | ReliantUNIX | BSDI |
Digital Unix | DGUX |
Ultrix
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 (see CFLAGS_SHLIB, LDFLAGS_SHLIB and LDFLAGS_SHLIB_EXPORT below) manually or at least make sure a Perl 5 interpreter is installed from which Apache can guess the options.
For more in-depth information about DSO support in Apache 1.3 please read the document htdocs/manual/dso.html carefully. Especially the section entitled "Advantages & Disadvantages" because using the DSO mechanism can have strange side-effects if you are not careful. BE WARNED!
The next step is to configure the Apache source tree for your particular platform and personal requirements. The most important setup here is the location prefix where Apache is to be installed later, because Apache has to be configured for this location to work correctly. But there are a lot of other options available for your pleasure.
For a short impression of what possibilities you have, here is a typical example which compiles Apache for the installation tree /sw/pkg/apache with a particular compiler and flags plus the two additional modules mod_rewrite and mod_proxy for later loading through the DSO mechanism:
$ CC="pgcc" OPTIM="-O2" \ ./configure --prefix=/usr/local/apache \ --enable-module=rewrite --enable-shared=rewrite \ --enable-module=proxy --enable-shared=proxy
For a complete list of the available options, type the following command:
./configure --help
See also the file README.configure
for listings of
example configurations.
Now you can build the various parts which form the Apache package by simply running the command
$ make
Please be patient here, this takes approximately 2 minutes to complete under a Pentium-166/FreeBSD-2.2 system, dependent on the amount of modules you have enabled.
Now its time to install the package under the configured installation
PREFIX
(see the --prefix
option above):
$ make install
In the following examples, PREFIX
is not the literal string
"PREFIX", but whatever argument you provided to
the--prefix
option.
All configuration of Apache is performed in the
src
directory of the Apache distribution. Change
into this directory.
