How do I run apps as a non-root user in redhat 6/7 ?

in the past I just let the install rpm set up an non root userid for an application.  
Where I am now we download source need to run it as non-root user without the RPM package taking care of this for me.
This is for newer versions of Redhat !

Does the rpm su to the user, runuser user another way of running an app ( apache, tomcat etc ) as a non-root user?

you need to "su" to root or equivalent like sudo and then install / run as root

the rpm cannot su as there are too many different ways to validate
Can you elaborate more on requirement? Can you give example?
I think this deals with setting up the run scripts
you would need to create a run script ref example /etc/init.d chkconfig line deals with when the service should start (which run levels) and similarly which run levels it should stop. ....

you need to include the requisite parameters in the start script to indicate that the app has to run using a non-root user after you create the non-root user that will be used by this app.
