You haven't mantioned your purpose to configure your own DNS server. I assume that you want forwarder type for DNS server and firewall is not configured in this server

1. You have to install "dnsmasq" server using yum.
#yum install dnsmasq*

2. start service on reboot
#chkconfig dnsmasq on

3. Start service
#service dnsmasq start

Now change your Clients DNS IP address to this machine and check.

If you are using Firewall (IPTables) then you need to configure following rules

iptables -I INPUT -p tcp --dport 53 -j ACCEPT
iptables -I INPUT -p udp --dport 53 -j ACCEPT
service iptables save

There are many kinds of DNS servers to talk alone. Before that, I suggest to be clear if you want to configure your Linux hosts to be able to resolve DNS queries from a DNS server, or to setup a DNS server that serves as a name resolution for your LAN.
