一、实验拓扑
RHEL5.9
--------------RHEL5.9(vmnet4)-------------------(vmnet4)
Win7
实验前提条件
1. 所有试验机在相同网络
2. DHCP服务器有固定IP
实验操作步骤：
1. 设置ip
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
HWADDR=00:0c:29:5d:a8:80
IPADDR=192.168.10.253
PREFIX=24
[root@localhost ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=dhcpser.tarena.com
GATEWAY=192.168.10.254
[root@localhost ~]# cat /etc/resolv.conf
search tarena.com
nameserver 192.168.10.254
nameserver 202.106.0.20
[root@localhost ~]# service network restart
[root@localhost ~]# chkconfig network on
验证：
[root@dhcpser ~]# ifconfig eth0
[root@dhcpser ~]# route -n
[root@dhcpser ~]# hostname
[root@dhcpser ~]# cat /etc/resolv.conf
2. 安装软件包
[root@dhcpser ~]# rpm -q dhcp //
放入RHEL5.9 iso镜像
[root@dhcpser ~]# cd /misc/cd/Server //
[root@dhcpser Server]# ls *dhcp*
[root@dhcpser Server]# rpm -ivh dhcp-3(tab)
[root@dhcpser Server]# rpm -q dhcp
dhcp-3.0.5-31.el5_8.1
3. 修改配置文件
ddns-update-style interim;
ignore client-updates;
subnet 192.168.0.0 netmask 255.255.255.0 {
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
range dynamic-bootp 192.168.0.128 192.168.0.254;
default-lease-time 21600;
max-lease-time 43200;
host ns {
next-server marvin.redhat.com;
hardware ethernet 12:34:56:78:AB:CD;
fixed-address 207.175.42.254;
}
}
4. 启动服务
[root@dhcpser ~]# rpm -ql dhcp | grep init.d
/etc/rc.d/init.d/dhcpd
/etc/rc.d/init.d/dhcrelay
[root@dhcpser ~]# service dhcpd restart
[root@dhcpser ~]# chkconfig dhcpd on
5. 验证
Linux：
# dhclient -d eth0 临时获取
# dhclient -r eth0 释放
Windows：
cmd>ipconfig /release 释放ip
cmd>ipconfig /renew 重新获取ip

一、实验拓扑
----------------RHEL5.9_A----（vmnet1）----RHEL5.9_B-----------
RHEL5.9_A： 192.168.10.253/24
RHEL5.9_B： 192.168.10.20/24
实验总结：
搭建DHCP服务器基本步骤和实验报告格式
1.DHCP搭建环境准备
a.启动三台虚拟机，一台用作DHCP服务器，一台Linux客户机，一台Win客户机，分别取名DHCP.Server.Tarena.com LinuxClient WINClient
b.为服务器配置IP 设置 设置配置文件 #vim /etc/sysconfig/network 写网关
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=
c.启动网关
#server network restart //开启服务
#chkconfig network //确保随启动自启动
2.安装软件
#yum -y install dhcp
3.dhcp 主要配置文件 /etc/dhcp.conf
/usr/share/doc/dhcp-*/dhcpd.sample
执行程序：/usr/sbin/dhcpd
4.服务脚本 /etc/init.d/dhcpd
5.执行参数配置 /etc/sysconfig/dhcpd
