10.2.4.2. The mod_ssl Module

The configuration for mod_ssl has been moved from the httpd.conf file into the /etc/httpd/conf.d/ssl.conf file. For this file to be loaded, and for mod_ssl to work, the statement Include conf.d/*.conf must be in the httpd.conf file as described in Section 10.2.1.3, “Dynamic Shared Object (DSO) Support”.
ServerName directives in SSL virtual hosts must explicitly specify the port number.
For example, the following is a sample Apache HTTP Server 1.3 directive: 
<VirtualHost _default_:443>
    # General setup for the virtual host
    ServerName ssl.example.name
    ...
</VirtualHost>
To migrate this setting to Apache HTTP Server 2.0, use the following structure: 
<VirtualHost _default_:443>
    # General setup for the virtual host
    ServerName ssl.host.name:443
    ...
</VirtualHost>
It is also important to note that both the SSLLog and SSLLogLevel directives have been removed. The mod_ssl module now obeys the ErrorLog and LogLevel directives. Refer to Section 10.5.35, “ ErrorLog ” and Section 10.5.36, “ LogLevel ” for more information about these directives.
