Disable apache2 Server from auto-starting upon Boot-up

 Title: Disable apache2 Server from auto-starting upon Boot-up

you could simply disable it by:

sudo update-rc.d apache2 disable

and then if you would liek to enable it again:

sudo update-rc.d apache2 enable

depending on the project i am working on, it is handy to have the service conveniently available, if i wish to re-enable it.
