DNS settup.

Hi I am newbe to DNS, I would like to setup my own DNS server.
Following is DNS server configuration.

Linux 8.0 server.
Bind BIND 9.2.1
If possible Apache, MySql on same server (Small setup, upto 80 virtual domains, & LAN users.)
eth0 (IP : 1.2.3.4)

Linux Router Server having 3 ethernet cards.
eth0 connected to IPS for bandwidth. (IP : 6.7.8.9)
eth1 for local LAN (IP : 192.168.1.1)
eth2 goes to DNS and apache server, Mysql (IP : 1.2.3.3)

I have received 2 Static IP addresses from ISP. (1.2.3.4 & 1.2.3.5 respectively)
I will be registering domain "www.xyz.com" to network solutions giving

primary name server NS1.xyz.com 1.2.3.4
secondary name server NS2.xyz.com 1.2.3.5

I don't want to use redhat 8.0 GUI for DNS setting since mailing list says it is buggy. So want to deactivate. Please tell me how?

Can you guide me How I should configure setup and in which files.

I tried to go through Archives but could not figureout and totally confused.
Thanks for support
