Did I forget something? Should he give me something on port 8080 and on 4848 admin panel?
Or does he still need some kind of nginix webserver?
And where is Apache from? I didn't put it on.

Answer 1

ps -ef | grep java
shows what? What is written to the standard output at startup, are there definitely no errors there? What's in the domain logs?

Answer 2

And what should happen next?
The service listens on ports if you cannot reach them. Then that's another problem.
put iptables -S here.
==============================
Apache is very often installed on VDS.
The last time I took VDS 2 months ago for tests. Also on Centos.
At the start, I had an Apache bind and a bunch of other services that I just turned off.
