How Can I change Apache2 Primary server Port address to 8080, on a Linux system?

I need to change the port address of my apache2 web server. The %26quot;Listen = 8080%26quot;, in httpd.confg only change the virtual host Port, not the primary port. What am I missing?How Can I change Apache2 Primary server Port address to 8080, on a Linux system?
Did you try using the listen command with full IP?



Listen 192.168.1.100:8080



Also, I don't use the = in my .conf file.
