</example>
<p>This will create a new directory under the current directory

the script <program>configure</program> included in
the root directory of the distribution. (Developers downloading

+ an unreleased version of the Apache source tree will need to have
<code>autoconf</code> and <code>libtool</code> installed and will
need to run <code>buildconf</code> before proceeding with the next
steps. This is not necessary for official releases.)</p>
<p>Also at this point, you can specify which <a
href="programs/configure.html#optionalfeatures">features</a> you
want included in Apache by enabling and disabling <a
- href="mod/">modules</a>. Apache comes with a <a
- href="mod/module-dict.html#Status">Base</a> set of modules included by
- default. Other modules are enabled using the
+ href="mod/">modules</a>. Apache comes with a wide range of modules
+ included by default. They will be compiled as

+ or unloaded at runtime.
+ You can also choose to compile modules statically by using the option
+ <code>--enable-<var>module</var>=static</code>.</p>
+
+ <p>Additional modules are enabled using the
<code>--enable-<var>module</var></code> option, where
<var>module</var> is the name of the module with the
<code>mod_</code> string removed and with any underscore converted
- to a dash. You can also choose to compile modules as <a
- href="dso.html">shared objects (DSOs)</a> -- which can be loaded

- <code>--enable-<var>module</var>=shared</code>. Similarly, you can
- disable Base modules with the

<code>--disable-<var>module</var></code> option. Be careful when
using these options, since <program>configure</program> cannot warn you
if the module you specify does not exist; it will simply ignore the
location of your compiler, libraries, or header files. This is
done by passing either environment variables or command line
options to <program>configure</program>. For more information, see the

+ <program>configure</program> manual page. Or invoke

<p>For a short impression of what possibilities you have, here
is a typical example which compiles Apache for the installation

<p>When <program>configure</program> is run it will take several minutes to

<section id="upgrading"><title>Upgrading</title>
<p>The first step in upgrading is to read the release announcement
and the file <code>CHANGES</code> in the source distribution to
find any changes that may affect your site. When changing between
- major releases (for example, from 1.3 to 2.0 or from 2.0 to 2.2),
+ major releases (for example, from 2.0 to 2.2 or from 2.2 to 2.4),
there will likely be major differences in the compile-time and
run-time configuration that will require manual adjustments. All
- modules will also need to be upgraded to accomodate changes in the
+ modules will also need to be upgraded to accommodate changes in the
module API.</p>
<p>Upgrading from one minor version to the next (for example, from
- 2.0.55 to 2.0.57) is easier. The <code>make install</code>
+ 2.2.55 to 2.2.57) is easier. The <code>make install</code>
process will not overwrite any of your existing documents, log
files, or configuration files. In addition, the developers make
every effort to avoid incompatible changes in the
module API between minor versions. In most cases you should be able to
use an identical <program>configure</program> command line, an identical
configuration file, and all of your modules should continue to
- work. (This is only valid for versions after 2.0.41; earlier
- versions have incompatible changes.)</p>
+ work.</p>
<p>To upgrade across minor versions, start by finding the file
<code>config.nice</code> in the <code>build</code> directory of
$ ./config.nice<br />
$ make<br />
$ make install<br />
- $ <em>PREFIX</em>/bin/apachectl stop<br />
- $ <em>PREFIX</em>/bin/apachectl start<br />
+ $ <em>PREFIX</em>/bin/apachectl -k graceful-stop<br />
+ $ <em>PREFIX</em>/bin/apachectl -k start<br />
</example>
<note type="warning">You should always test any new version in your
different port (by adjusting the <directive
module="mpm_common">Listen</directive> directive) to test for any
incompatibilities before doing the final upgrade.</note>
+
+ <p>You can pass additional arguments to <code>config.nice</code>,
+ which will be appended to your original <program>configure</program>
+ options:</p>
+
+ <example>
+ $ ./config.nice --prefix=/home/test/apache --with-port=90

+<section id="thirdp"><title>Third-party packages</title>
+
+ <p>A large number of third parties provide their own packaged
+ distributions of the Apache HTTP Server for installation on
+ particular platforms. This includes the various Linux distributions,
+ various third-party Windows packages, Mac OS X, Solaris, and many
+ more.</p>
+
+ <p>Our software license not only permits, but encourages, this kind
+ of redistribution. However, it does result in a situation where the
+ configuration layout and defaults on your installation of the server
+ may differ from what is stated in the documentation. While
+ unfortunate, this situation is not likely to change any time
+ soon.</p>
+
+ <p>A <a
+ href="http://wiki.apache.org/httpd/DistrosDefaultLayout">description
+ of these third-party distrubutions</a> is maintained in the HTTP
+ Server wiki, and should reflect the current state of these
+ third-party distributions. However, you will need to familiarize
+ yourself with your particular platform's package management and
+ installation procedures.</p>
