25.2.2.4.2. 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 25.2.2.1.3, “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 ErrorLog and LogLevel for more information about these directives.
For more on this topic, refer to the following documentation on the Apache Software Foundation's website:

Important

Due to the vulnerability described in POODLE: SSLv3 vulnerability (CVE-2014-3566), Red Hat recommends disabling SSL and using only TLSv1.1 or TLSv1.2. Backwards compatibility can be achieved using TLSv1.0. Many products Red Hat supports have the ability to use SSLv2 or SSLv3 protocols, or enable them by default. However, the use of SSLv2 or SSLv3 is now strongly recommended against.
