How to configure DHCP server in RedHat Linux

DHCP means Dynamic Host Configuration Protocol. It is one of the most important server in networking. Even everywhere  at every place when we are in network, we are using  it. Configuration of it is very very simple. 

[root@princy ~]#yum -y install dhcp

[root@princy ~]#vi /etc/dhcp/dhcpd.conf                       

 

# create new

# specify domain name in file dhcpd.conf

option domain-name "hackers001.linux";

# pecify DNS's hostname or IP address

option domain-name-servers   hackers001.linux.redhat;

# default lease time

default-lease-time 600;

# max lease time

max-lease-time 7200;

# this DHCP server to be declared valid

authoritative;

# specify network address and subnet mask

subnet 192.168.0.1 netmask 255.255.255.0 {

# specify the range of lease IP address

range dynamic-bootp 192.168.0.12  192.168.0.120;

# specify broadcast address

option broadcast-address 192.168.0.255;

# specify default gateway

option routers 192.168.0.1;

}

[root@princy ~]#systemctl start dhcpd.service 
[root@princy ~]#systemctl enable dhcpd.service
