If you choose to use the new default configuration file for version 2.2, you will find that it has been greatly simplified enable SSL support, you should edit httpd.conf to include the relevant mod_ssl directives and then use apachectl start to start the server. An example configuration to activate mod_ssl has been included the Perl Compatible Regular Expression Library (PCRE) is now included. httpd can be configured to use a system installation of PCRE by passing the --with-pcre flag to configure.

describes changes in server behavior that might require you to change your configuration or how you use the server in order to continue using 2.4 as you are currently using 2.2. To take advantage of new by the more expressive RequireAny, RequireNone, and RequireAll. If you use mod_authz_dbm, you must port your configuration to use Require dbm-group ... in place of Require group .... Access control In any effect, other than to emit a warning if it's used with any value other than none. You need to use other configuration settings to replace it in 2.4. AllowOverride now defaults to None. EnableSendfile
