本次试验，环境如下：
宿主机操作系统：Windows XP
虚拟机操作系统：Red Hat Enterprise Linux 5
一. 需拟机的网卡模式：设置为网桥，并手动设置对应网卡的ip地址，如为多网卡，需要修改/etc/sysconfig/dhcpd文件中的DHCPDARGS=eth*
查询主机是否己经安装dhcp软件： rpm -qa | grep dhcp
出现dhcpv6-client-1.0.10-16.el5
dhcp-3.0.5-18.el5
dhcp-devel-3.0.5-18.el5 为己安装
如未安装，挂载cdrom: mount /dev/cdrom /mnt/cdrom ,然后安装dhcpd服务软件
二. 下面进行dhcp服务软件的配置 ：
初始安装dhcpd软件后，使用的配置文件为： /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample
执行：cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf 这样就己经拥有了一份最原始的dhcp服务配置。
dhcpd.conf的原始配置如下：
ddns-update-style interim; ignore client-updates; subnet 192.168.0.0 netmask 255.255.255.0 { //设置子网及掩码 # --- default gateway option routers 192.168.0.1; option subnet-mask 255.255.255.0; option nis-domain "domain.org"; option domain-name "domain.org"; option domain-name-servers 192.168.1.1; option time-offset -18000; # Eastern Standard Time # option ntp-servers 192.168.1.1; # option netbios-name-servers 192.168.1.1; # --- Selects point-to-point node (default is hybrid). Don't change this unless # -- you understand Netbios very well # option netbios-node-type 2; range dynamic-bootp 192.168.0.128 192.168.0.254; //dhcp允许分配的ip池 default-lease-time 21600; max-lease-time 43200; # we want the nameserver to appear at a fixed address host ns { next-server marvin.RedHat.com; hardware ethernet 12:34:56:78:AB:CD; fixed-address 207.175.42.254; } }然后按需修改即可。
