1> check whether the DHCP server software is installed, do not install first, the default system is not installed. rpm-qa | grep dhcp rpm-ivh dhcp-3.0.1-12_EL.i386.rpm
2> Modify/etc/dhcpd. the conf file is empty by default and needs to be created by yourself. However, there is a template file in the system. You can copy the template file and modify the template file as required.
Cp/usr/share/doc/dhcp-3.0.1/dhcpd. conf. sample/etc/sample
3> start service dhcpd start
2. Client Configuration
Set the interface configuration file BOOTPROTO = dhcp, and restart the network interface or dhclient.

XX company needs to build a DHCP server in the LAN as follows
1> the default lease period is 21600 S.
2> the maximum lease time is 43200 S.
3> the domain name of all hosts in the LAN is abc.com.
4> the IP address of the DNS server used by the client is 192.168.1.1.
5> declare that the IP address range used for Dynamic Allocation in the subnet 192.168.1.0/24 is 192.168.1.100 ~ 192.168.1.200. The subnet mask of the allocated IP address is 255.255.255.0. The default gateway address is 192.168.1.1.
6> In the subnet 192.168.1.0/24, a server host named SERVER01 needs to be assigned a fixed IP address 192.168.1.11. the MAC address of the server network interface is b0: c0: c3: 22: 46: 81. other configurations of the server 01 host use the default configurations of the subnet,
The configuration file in dhcpd. conf is as follows:
