| |
| <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 |

| |
| |
| <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> |

| <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 |

| <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. But all |
| modules must be recompiled before being loaded.</p> |
