Hello, can i ask for some advice on bonescript?

I’m trying to use my beagle bone black (rev. c) as a web server with apache2
but it seems to be the default port for apache2 is set to 8080
and from my research, port 80 is taken by node.js which is activated by bonescript.

what i want to do is switch two ports;
8080 for bonescript for my later projects.
80 for apache2 for my blog.

i tried to uninstall node.js and was able to run apache2 on port 80 but i also want to keep node.js on 8080.

how can i make bonescript run on port 8080?

thank you for reading and answers would be greatly appreciated.
