Subject [users@httpd] apache 2.4 enable SSL for simple VirtualHost *:8843
Date Wed, 17 Dec 2014 00:55:21 GMT
I'm unable to simply enable SSL for a VirtualHost using a very simple

I'm recently upgraded Ubuntu 12 to Ubuntu 14.  apache was upgraded from 2.2
to 2.4.7 .  I've checked the 2.4 docs for 2.2.->2.4 changes and reviewed my
configuration scripts in depth.
I can create an unencrypted VirtualHost (http) but not one an encrypted one
(https) on port 8843.  I can browse to the site just fine with
http://server:8843 (I see the expected index.html file).  If I try
https://server:8843 I get "ssl_error_rx_record_too_long" error (using
Firefox 33).

I've tried many options within the configuration files.  I haven't
drastically changed any pre-configured apache configuration files.  The
apache2 service does see my changes but just seems to not enable SSL.
Here is a selected summary of all the related files.  Can anyone identify
what I'm missing?

The user that runs apache2 is user www-data .
I have tested that www-data and root can access the key files
/etc/ssl/certs/test1.cert.pem /etc/ssl/private/test1.cert.key .

  $ sudo -u www-data cp /etc/ssl/certs/test1.cert.pem
/etc/ssl/private/test1.cert.key /tmp/

I have checked that /usr/lib/apache2/modules/ exists and is

  $ sudo -u www-data ls -l /usr/lib/apache2/modules/
  -rwxr-xr-x 1 root root 211184 Jul 22 07:38

I have tailed the relevant apache2 logs and checked for errors.  I see
these SSL related message on startup. (including one skip message for, but then later there is a resuming message)

The openssl binary runs and supports ciphers:

  $ openssl ciphers

I check the apache2ctl binary compilations settings

  $ apache2ctl -V

I checked apache2ctl settings

  $ apache2ctl -S

  VirtualHost configuration:

  Define: DUMP_RUN_CFG
  User: name="www-data" id=33
  Group: name="www-data" id=33

The apache2ctl syntax check is OK.

  $ apache2ctl -t
  AH00558: apache2: Could not reliably determine the server's fully
qualified domain name, using Set the 'ServerName' directive
globally to suppress this message
  Syntax OK

The file /etc/init.d/apache2 does start apache using /usr/sbin/apache2ctl
(and not /usr/sbin/apache2 ).

Any ideas on what I need to enable SSL for this VirtualHost ?
Again, I can see HTTP response on 8443 but never HTTPS.
