<h1 align="CENTER">Upgrading to 2.0 from 1.3</h1>
|
|
|
|
<p>In order to assist folks upgrading, we maintain a document
|
|
describing information critical to existing Apache users. These
|
|
are intended to be brief notes, and you should be able to find
|
|
more information in either the <a
|
|
href="new_features_2_0.html">New Features</a> document, or in
|
|
the <code>src/CHANGES</code> file.</p>
|
|
|
|
<h3>Compile-Time Configuration Changes</h3>
|
|
|
|
<ul>
|
|
<li>Apache now uses an <code>autoconf</code> and
|
|
<code>libtool</code> system for <a
|
|
href="install.html">configuring the build processes</a>.
|
|
Using this system is similar to, but not the same as, using
|
|
the APACI system in Apache 1.3.</li>
|
|
|
|
<li>In addition to the usual selection of modules which you
|
|
can choose to compile, Apache 2.0 has moved the main part of
|
|
request processing into <a href="mpm.html">Multi-Processing
|
|
Modules</a> (MPMs).</li>
|
|
</ul>
|
|
|
|
<h3>Run-Time Configuration Changes</h3>
|
|
|
|
<ul>
|
|
<li>Many directives that were in the core server in Apache
|
|
1.3 are now in the MPMs. If you wish the behavior of the
|
|
server to be as similar as possible to the behavior of Apache
|
|
1.3, you should select the <a
|
|
href="mod/prefork.html">prefork</a> MPM. Other MPMs will have
|
|
different directives to control process creation and request
|
|
processing.</li>
|
|
|
|
<li>The <code>CacheNegotiatedDocs</code> directive now takes
|
|
the argument <code>on</code> or <code>off</code>. Existing
|
|
instances of <code>CacheNegotiatedDocs</code> should be
|
|
replaced with <code>CacheNegotiatedDocs on</code>.</li>
|
|
|
|
<li>
|
|
The <code>ErrorDocument</code> directive no longer uses a
|
|
quote at the beginning of the argument to indicate a text
|
|
message. Instead, you should enclose the message in double
|
|
quotes. For example, existing instances of
|
|
|
|
<blockquote>
|
|
<code>ErrorDocument 403 "Some Message</code>
|
|
</blockquote>
|
|
should be replaced with
|
|
|
|
<blockquote>
|
|
<code>ErrorDocument 403 "Some Message"</code>
|
|
</blockquote>
|
|
As long as the second argument is not a valid URL or
|
|
pathname, it will be treated as a text message.
|
|
</li>
|
|
|
|
<li>The <code>AccessConfig</code> and
|
|
<code>ResourceConfig</code> directives no longer exist.
|
|
Existing instances of these directives can be replaced with
|
|
the <a href="mod/core.html#include"><code>Include</code></a>
|
|
directive which has equivalent functionality. If you were
|
|
making use of the default values of these directives without
|
|
including them in the configuration files, you may need to
|
|
add <code>Include conf/access.conf</code> and <code>Include
|
|
conf/srm.conf</code> to your httpd.conf. In order to assure
|
|
that Apache reads the configuration files in the same order
|
|
as was implied by the older directives, the
|
|
<code>Include</code> directives should be placed at the end
|
|
of httpd.conf, with the one for <code>srm.conf</code>
|
|
preceding the one for <code>access.conf</code>.</li>
|
|
|
|
<li>The <code>BindAddress</code> directive no longer exists.
|
|
Equivalent functionality is provided with the more flexible
|
|
<code><a href="mod/mpm_common.html#listen">Listen</a></code>
|
|
directive.</li>
|
|
|
|
<li>The <code>ServerType</code> directive no longer exists.
|
|
The method used to serve requests is now determined by the
|
|
selection of MPM. There is currently no MPM designed to be
|
|
launched by inetd.</li>
|
|
|
|
<li>The mod_log_agent and mod_log_referer modules which
|
|
provided the <code>AgentLog</code>, <code>RefererLog</code>
|
|
and <code>RefererIgnore</code> directives have been removed.
|
|
Agent and referer logs are still available using the <a
|
|
href="mod/mod_log_config.html#customlog">CustomLog</a>
|
|
directive of mod_log_config.</li>
|
|
|
|
<li>The <code>AddModule</code> and
|
|
<code>ClearModuleList</code> directives no longer exist.
|
|
These directives where used to ensure that modules could be
|
|
enabled in the correct order. The new Apache 2.0 API allows
|
|
modules to explicitly specify their ordering, eliminating the
|
|
need for these directives.</li>
|
|
</ul>
|
|
|
|
<h3>Misc Changes</h3>
|
|
|
|
<ul>
|
|
<li>The <code>httpd</code> command line option
|
|
<code>-S</code> which was used for printing the virtual host
|
|
configuration has been replaced by <code>-t -D
|
|
DUMP_VHOSTS</code>.</li>
|
|
|
|
<li>The module mod_auth_digest, which was experimental in
|
|
Apache 1.3 is now a standard module.</li>
|
|
|
|
<li>The mod_mmap_static module, which was experimental in
|
|
Apache 1.3 has been replaced with mod_file_cache.</li>
|
|
|
|
<li>The distribution has been completely reorganized so that
|
|
it no longer contains an independent <code>src</code>
|
|
directory. Instead, the sources are logically organized under
|
|
the main distribution directory, and installations of the
|
|
compiled server should be directed to a separate
|
|
directory.</li>
|
|
</ul>
|
|
|
|
<h3>Third Party Modules</h3>
|
|
|
|
<p>Extensive changes were made to the server API in Apache 2.0.
|
|
Existing modules designed for the Apache 1.3 API will
|
|
<strong>not</strong> work in Apache 2.0 without modification.
|
|
Details are provided in the <a href="developer/">developer
|
|
documentation</a>.</p>
