一、安装dhcp软件

[root@dns-server ~]# yum install dhcp -y

二、配置dhcp参数

[root@dns-server ~]# cat /etc/dhcp/dhcpd.conf    
#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp*/dhcpd.conf.sample
#   see 'man 5 dhcpd.conf'
#
subnet 192.168.3.0 netmask 255.255.255.0 {  #这个是设置ip网段和子网掩码
  range 192.168.3.10 192.168.3.40;              #自动分配的ip地址段
  option domain-name-servers 192.168.3.1;       #dns服务器地址
  option domain-name "dns.test.com";            #dns服务器名字
  option routers 192.168.3.254;                 #网关
  option broadcast-address 192.168.3.255;       #广播地址
  default-lease-time 600;                       
  max-lease-time 7200;                          
}
[root@dns-server ~]# /etc/init.d/dhcpd start

三、在客户端测试

C:\Documents and Settings\Administrator>ipconfig

Windows IP Configuration


Ethernet adapter 本地连接:

        Connection-specific DNS Suffix  . : dns.test.com
        IP Address. . . . . . . . . . . . : 192.168.3.10
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 192.168.3.254

C:\Documents and Settings\Administrator>

四、dhcp参数模板

[root@dns-server ~]# cat /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample 
# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#

# option definitions common to all supported networks...
option domain-name "example.org";
option domain-name-servers ns1.example.org, ns2.example.org;

default-lease-time 600;
max-lease-time 7200;

# Use this to enble / disable dynamic dns updates globally.
#ddns-update-style none;

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
#authoritative;

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;

# No service will be given on this subnet, but declaring it helps the 
# DHCP server to understand the network topology.

subnet 10.152.187.0 netmask 255.255.255.0 {
}

# This is a very basic subnet declaration.

subnet 10.254.239.0 netmask 255.255.255.224 {
  range 10.254.239.10 10.254.239.20;
  option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org;
}

# This declaration allows BOOTP clients to get dynamic addresses,
# which we don't really recommend.

subnet 10.254.239.32 netmask 255.255.255.224 {
  range dynamic-bootp 10.254.239.40 10.254.239.60;
  option broadcast-address 10.254.239.31;
  option routers rtr-239-32-1.example.org;
}

# A slightly different configuration for an internal subnet.
subnet 10.5.5.0 netmask 255.255.255.224 {
  range 10.5.5.26
