Kong api gateway deployment issue on centos 8

I have successfully installed and setup kong on centos 8 server.

But need to know how to access from internet. while it successfully works with

curl -i http://localhost:8000/

I am not using Docker and also not interested to use it.

Please guide me or help on Production deployment configuration on centos. I am newbie so i am facing challenges and stuck from last 2 day

Thanks in Advance
