Resolution

1. (conditional) If not yet configured, Enable the SSL module and set the Apache Server Flags to SSL:
   • From a terminal window: edit file /etc/sysconfig/apache2
   • Verify ssl is found in the list of APACHE_MODULES.
     Note: If it is not, please run the following command, which should enable the ssl module and add it to this list:
     sudo a2enmod ssl
   • From this same file, please find APACHE_SERVER_FLAGS=”” and add SSL in between the quotations.
   • Create a virtual host for ssl by copying from the template:
     cp /etc/apache2/vhosts.d/vhost-ssl.template /etc/apache2/vhosts.d/vhost-ssl.conf
     
2. Configure Apache to use new certificate files:
   • From a terminal window: cd /etc/apache2/vhosts.d/
   • Edit file vhost-ssl.conf
   • Update paths to the appropriate file(s) as needed:
     • SSLCertificateFile <directory to the cert (*.cert)>
     • SSLCertificateKeyFile <path to the private key (*.key)>
     • SSLCertificateChainFile <path to CA Chain file(s)>
     • SSLCACertificateFile <path to bundles>
   • Save and Close.
   • From a Terminal window: type rcapache2 restart and press Enter.
