This machine used Debain 6, apache was installed using apt-get
In oder to change the default port that apache ran on I had to change two files
first in
/etc/apache2/ports.conf
i changes the lines
NameVirtualHost *:80
Listen 80
to
NameVirtualHost *:8000
Listen 8000
Then I needed to change the actual site virtual host file
/etc/apache2/sites-enabled/000-default
I found the line
and changed it to
afterworlds I restarted the server using
/etc/init.d/apache2 restart
