Sorry but I am new to this, is there a guide to do this?

Where can I find the documentation to do that?

[root@server ~]# netstat -tnlp | grep 80
tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN 6874/python
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 8375/nginx
[root@server ~]#

Any reason why it requires NGINX? is that for the backend or front end? Will it conflict with Apache?
