need help to configure mod_ajp_proxy for https two ports.

[khan83]

I have two websites (for example example1.com and example2.com)
I have installed Apach 2.x on ubuntu 16 and configured the virtual hosts: They are working fine for port 80.

Now I want to install and run two ofbiz instances running like this:
https://127.0.0.1:8443/ecommerce/control/main
https://127.0.0.1:8445/ecommerce/control/main

How can I configure https (SSL) in Apache's virtual host using mod_ajp_proxy? And do I need must to install SSL certificate ?

Khan
