These are intended to be brief notes, and you should be able to find more information in either the <a href="new_features_2_2.html">New Features</a> document, or in the <code>src/CHANGES</code> file.</p> <p>This document describes only the changes from 2.0 to 2.2. If you are upgrading from version 1.3, you should also consult the <a href="http://httpd.apache.org/docs/2.0/upgrading.html">1.3 to 2.0 upgrading document.</a></p></div><div id="quickview"><ul id="toc"><li><img alt="" src="./images/down.gif" /> <a href="#compile-time">Compile-Time Configuration Changes</a></li><li><img alt="" src="./images/down.gif" /> <a href="#run-time">Run-Time Configuration Changes</a></li><li><img alt="" src="./images/down.gif" /> <a href="#misc">Misc Changes</a></li><li><img alt="" src="./images/down.gif" /> <a href="#third-party">Third Party Modules</a></li></ul><h3>See also</h3><ul class="seealso"><li><a href="new_features_2_2.html">Overview of new features in Apache 2.2</a></li></ul></div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div><div class="section"><h2><a name="compile-time" id="compile-time">Compile-Time Configuration Changes</a></h2> <p>The compilation process is very similar to the one used in version 2.0. Your old <code>configure</code> command line (as found in <code>build/config.nice</code> in the installed server directory) can be used in some cases. The most significant change required will be to account for changes in module names, in particular for the authentication and authorization modules. Some details of changes:</p> <ul> <li>mod_imap has been renamed to <code class="module"><a href="./mod/mod_imagemap.html">mod_imagemap</a></code></li> <li>mod_auth has been split up into <code class="module"><a href="./mod/mod_auth_basic.html">mod_auth_basic</a></code>, <code class="module"><a href="./mod/mod_authn_file.html">mod_authn_file</a></code>, <code class="module"><a href="./mod/mod_authz_user.html">mod_authz_user</a></code>, and <code class="module"><a href="./mod/mod_authz_groupfile.html">mod_authz_groupfile</a></code></li> <li>mod_access has been renamed to <code class="module"><a href="./mod/mod_authz_host.html">mod_authz_host</a></code></li> <li>mod_auth_ldap has been renamed to <code class="module"><a href="./mod/mod_authnz_ldap.html">mod_authnz_ldap</a></code></li> <li>Upgraded to require the APR 1.0 API.</li> <li>Updated bundled PCRE version to 5.0</li> </ul> </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div><div class="section"><h2><a name="run-time" id="run-time">Run-Time Configuration Changes</a></h2> <p>Your existing version 2.0 config files and startup scripts can usually be used unchanged in version 2.2. Some small adjustments may be necessary for particular configurations as discussed below. In addition, if you dynamically load the standard modules using the <code class="directive"><a href="./mod/mod_so.html#loadmodule">LoadModule</a></code> directive, then you will need to account for the module name changes mentioned above.</p> <p>If you choose to use the new default configuration file for version 2.2, you will find that it has been greatly simplified by removing all but the most essential configuration settings. A set of example configuration settings for more advanced features is present in the <code>conf/extra/</code> directory of the installed server. Default configuration files are installed in the <code>conf/original</code> directory.</p> <p>Some runtime configuration changes that you may notice:</p> <ul> <li>The <code class="program"><a href="./programs/apachectl.html">apachectl</a></code> option <code>startssl</code> is no longer available. To enable SSL support, you should edit <code>httpd.conf</code> to include the relevant <code class="module"><a href="./mod/mod_ssl.html">mod_ssl</a></code> directives and then use <code>apachectl start</code> to start the server. An example configuration to activate <code class="module"><a href="./mod/mod_ssl.html">mod_ssl</a></code> has been included in <code>conf/extra/httpd-ssl.conf</code>.</li> <li>The default setting of <code class="directive"><a href="./mod/core.html#usecanonicalname">UseCanonicalName</a></code> is now <code>Off</code>. If you did not have this directive in your config file, you can add <code>UseCanonicalName On</code> to retain the old behavior.</li> <li>The module <code class="module"><a href="./mod/mod_userdir.html">mod_userdir</a></code> will no longer act on requests unless a <code class="directive"><a href="./mod/mod_userdir.html#userdir">UserDir</a></code> directive specifying a directory name is present in the config file. To restore the old default behavior, place the directive <code>UserDir public_html</code> in your config file.</li> <li>The directive <code class="directive">AuthDigestFile</code> from <code class="module"><a href="./mod/mod_auth_digest.html">mod_auth_digest</a></code> has been merged with <code class="directive"><a href="./mod/mod_authn_file.html#authuserfile">AuthUserFile</a></code> and is now part of <code class="module"><a href="./mod/mod_authn_file.html">mod_authn_file</a></code>.</li> </ul> </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div><div class="section"><h2><a name="misc" id="misc">Misc Changes</a></h2> <ul> <li>The module <code class="module"><a href="./mod/mod_cache.html">mod_cache</a></code>, which was experimental in Apache 2.0, is now a standard module.</li> <li>The module <code class="module"><a href="./mod/mod_disk_cache.html">mod_disk_cache</a></code>, which was experimental in Apache 2.0, is now a standard module.</li> <li>The module <code class="module"><a href="./mod/mod_mem_cache.html">mod_mem_cache</a></code>, which was experimental in Apache 2.0, is now a standard module.</li> <li>The module <code class="module"><a href="./mod/mod_charset_lite.html">mod_charset_lite</a></code>, which was experimental in Apache 2.0, is now a standard module.</li> <li>The module <code class="module"><a href="./mod/mod_dumpio.html">mod_dumpio</a></code>, which was experimental in Apache 2.0, is now a standard module.</li> </ul> </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div><div class="section"><h2><a name="third-party" id="third-party">Third Party Modules</a></h2> <p>Many third-party modules designed for version 2.0 will work unchanged with the Apache HTTP Server version 2.2.
