How to configure DHCP server in Linux

Dynamic Host Configuration protocol (DHCP): This server is very useful if you are running a company with multiple clients where it becomes hard to manually assign the IP address manually so you redirect the client to take the IP from the server which is done using a DHCP server.

subnet 10.10.10.0 netmask 255.255.255.0 {
range dynamic-bootp 10.10.10.220 10.10.10.230;
option broadcast-address 10.10.10.255;
option routers 10.10.10.235;

(Use these lines if you want to assign a fix IP to a particular client, mention client's IP with his/her MAC Address)

host ns {
hardware ethernet 08:00:07:26:c0:a5;
fixed-address 10.10.10.223;
}
}
Just save and restart your dhcp server services
# service dhcpd restart
Go to the client machine and make the following changes in ifcfg-eth0 file
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:0c:29:6d:55:dd
NM_CONTROLLED=no
ONBOOT=yes
USERCTL=yes
TYPE=Ethernet
BOOTPROTO=dhcp
IPV6INIT=no
Restart your network services
# service network restart
and check the new IP of the your client machine

As you can see the new IP assigned to this machine as assigned by my DHCP server
