Activate port 80 y 443

How can I activate port 80 and 443 in payara installed in AlmaLinux 9, in Centos 7 it was possible and now that I have obtained two new VPS I have the problem that I cannot change port 8080 to 80 and port 8181 to 443, now HTTPS and HTTP are configured, the ports are created and open, what else needs to be done?

First, I have no idea what “payara” is.

Generic steps for any service process that listens on port are:

  1. Set SELinux to allow the process to listen on port (if the service is confined) Using SELinux Red Hat Enterprise Linux 9 | Red Hat Customer Portal
  2. Set firewall to allow incoming traffic to port Chapter 1. Using and configuring firewalld Red Hat Enterprise Linux 9 | Red Hat Customer Portal
  3. Set the process to listen on the port. (In this case it would be in the config of that payara.)

If a process does listen on ports 8080 and 8181 and there is no easy way to change that, then plan B is to add port forwarding rules into the firewall, so that incoming traffic to 80 is redirected (a dNAT rule) to port 8080.
