Question : how to configure dhcp server  in linux ?


Question : step by step setting Dynamic Host Configuration Protocol in centos ?

DHCP :- Dynamic Host Configuration Protocol

IP - 10.20.2.33

Hostname - khandwa.lokesh.com

OS - CentOS 6

PORT - 68

DHCP (Dynamic Host Configuration Protocol) is a network protocol used for assigning IP address to network clients dynamically from predefined IP pool. It is useful for LAN network, but not generally used for production servers.
Step -1 

Install dhcp Package
# yum install dhcp* -y
 dhcp, dhcp server, dhcp protocol, dhcp port, dhcp full form, dhcp configuration,dhcp lease time, dhcp lease, dhcp relay, dhcp client, configure dhcp, configure dhcp server, dhcp settings, dhcpd, dhcpd.conf example

step  -2

Configure dhcp server
DHCP creates an empty configuration file /etc/dhcp/dhcpd.conf. Also it provides a sample configuration file at /usr/share/doc/dhcp*/dhcpd.conf.sample, which is very useful for configuring the DHCP server.
# vi /etc/dhcp/dhcpd.conf
 dhcp, dhcp server, dhcp protocol, dhcp port, dhcp full form, dhcp configuration,dhcp lease time, dhcp lease, dhcp relay, dhcp client, configure dhcp, configure dhcp server, dhcp settings, dhcpd, dhcpd.conf example

step - 3

Copy Dhcp configuration in /etc dir.
# cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf

Now open for configuration
option domain-name "lokesh.com";
option domain-name-servers khandwa.lokesh.com;
default-lease-time 600;
max-lease-time 7200;
authoritative;

log-facility local7;

DHCP Configuration file





We are configuring DHCP for 10.20.2.0/24 LAN network

# A slightly different configuration for an internal subnet.

subnet 10.20.2.0 netmask 255.255.255.0 {
range 10.20.2.40 10.20.2.50;
option domain-name-servers 10.20.2.33; # dns Server name
option domain-name "lokesh.com";
option routers 10.20.2.1; # default gateway
# option broadcast-address 10.5.5.31;
default-lease-time 600;
max-lease-time 7200;


set IP address to host
host client1 {
option host-name "client1.lokesh.com";
hardware ethernet 08:00:07:26:c0:a5;
fixed-address 10.20.2.50;
}










Restart Service

service dhcpd restart
To monitor dhcp leases just type in terminal
 dhcp, dhcp server, dhcp protocol, dhcp port, dhcp full form, dhcp configuration,dhcp lease time, dhcp lease, dhcp relay, dhcp client, configure dhcp, configure dhcp server, dhcp settings, dhcpd, dhcpd.conf example
DHCP Lease
vi /var/lib/dhcpd/dhcpd.leases
