Nginx – Virtualmin change apache port

I have added 'Listen 8080'

Did you really add a new line to listen on an alternate port, or did you change the existing listen directive?

From a stock lenny configuration file all you should have to do is change these a couple lines. I have a script that changes the stock config to listening port to 8000, and these are the only lines that get changed. After that apache is restarted and you should be done. Verify by running netstat -ntlp and you should see that apache is only listening on the port you set.

apache2/ports.conf

NameVirtualHost *:8000
Listen 8000

apache2/sites-available/default

<VirtualHost *:8000>

All SSL virtual hosts need an explicit "SSLEngine on"

The debian docs give you:

apache2 (2.2.13-2) unstable; urgency=high

* The new support for TLS Server Name Indication added in 2.2.12 causes
  Apache to be stricter about certain misconfigurations involving name
  based SSL virtual hosts. This may result in Apache refusing to start
  with the logged error message:

      Server should be SSL-aware but has no certificate configured
      [Hint: SSLCertificateFile]

  Up to 2.2.11, Apache accepted configurations where the necessary SSL
  configuration statements were included in the first (default)
  <Virtualhost *:443> block but not in subsequent <Virtualhost *:443>
  blocks. Starting with 2.2.12, every VirtualHost block used with SSL must
  contain the SSLEngine, SSLCertificateFile, and SSLCertificateKeyFile
  directives (SSLCertificateKeyFile is optional in some cases).

  When you encounter the above problem, the output of the command

      egrep -ir '^[^#]*(sslcertificate|sslengine|virtualhost)' \
          /etc/apache2/*conf* /etc/apache2/*enabled

  may be useful to determine which VirtualHost sections need to be changed.

  Also, formerly accidentially working constructs like

      <VirtualHost *:80 *:443>

  where one virtual host definition is used for both a non-ssl and a ssl
  virtual host do not work anymore. You can achieve a similar effect with

      <VirtualHost *:80>
      Include /.../vhost.include
      </VirtualHost>
      <VirtualHost *:443>
      SSLEngine on
      SSLCertificateFile ...
      Include /.../vhost.include
      </VirtualHost>
