Static IP on DHCP server
In order for the DHCP to start when CentOS is bootet it is necesary to have an static IP address on the interface connected to the network.
edit /etc/sysconfig/network-scripts/ifcfg-eth0 to contain
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
NETMASK=255.255.0.0
IPADDR=172.24.0.2Adding a default gateway
Edit the /etc/sysconfig/network file:
Add the following line to point at your default gateway.
GATEWAY=172.24.0.1Install DHCP server on Centos
