How to run apache2 & tomcat on the same vps?

Question

Apache HTTP Server

Hello!
The question is quite simple.... In short, I installed vesta (apache2+ nginx) + tomcat.
apache2 listens on port 8080
by default tomcat uses it too. accordingly, it started, but does not work...
Usually, it is recommended to change port 8080 to 80. But Nginx listens on port 80....
What port can I change Tomcat to so that it works correctly?
