实验报告DHCP的配置
一．实验拓扑
服务器 ---------- 客户机
二．实验条件。
所有试验机在相同的网段
DHCP服务器有固定的ip
三．实验步骤：
设置ip：
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
DEVICE=eth0
BOOTPROTO=none //这个选项不用改
HWADDR=00:0C:29:6F:36:09
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.4.5 //服务器上固定的ip地址
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
[root@localhost ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=tarena.com //修改用户名
[root@localhost ~]# service network restart //重启网络配置
[root@localhost ~]# chkconfig network on //重启配置
检查安装dhcp包
[root@localhost ~]# rpm -q dhcp //检查软件包是否安装
package dhcp is not installed //没有安装包的意思
[root@localhost ~]# cd /misc/cd/Server/
[root@localhost Server]# ls *dhcp* //搜索dhcp软件包
[root@localhost Server]# rpm -ivh dhcp-3.0.5-31.el5_8.1.x86_64.rpm //安装此包
[root@localhost Server]# rpm -q dhcp
dhcp-3.0.5-31.el5_8.1 //再次检查代表本机器已安装此包
修改配置文件
[root@localhost Server]# vim /etc/dhcpd.conf
ddns-update-style interim;
2 ignore client-updates;
3 subnet 192.168.4.0 netmask 255.255.255.0 { //前面的是网段，后面是的子网
4 option routers 192.168.4.254; //网关
5 option subnet-mask 255.255.255.0; //子网
6 option domain-name "tarena.com"; //名字自定义
7 option domain-name-servers 202.203.204.200; //DNS
8 range dynamic-bootp 192.168.4.10 192.168.4.200; //地址池网段
9 default-lease-time 21600;
10 max-lease-time 43200;
11 host ns {
12 next-server marvin.redhat.com;
13 hardware ethernet 12:34:56:78:AB:CD; //固定获取ip的机器的MAC地址
14 fixed-address 207.175.42.254; //固定ip地址
15 }
16 }
[root@localhost Server]# service dhcpd restart
启动 dhcpd： [确定]
[root@localhost Server]# chkconfig dhcpd on //两段全是重启服务服务的意思
验证：
[root@localhost ~]# service network restart //重启服务器的网卡设置
[root@localhost ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0C:29:B8:B7:76 //本机MAC地址
inet addr:192.168.4.200 Bcast:192.168.4.255 Mask:255.255.255.0 //dhcp获取得ip地址，一般以最大的开头，从大到小获取
inet6 addr: fe80::20c:29ff:feb8:b776/64 Scope:Link

[root@localhost ~]# ping 192.168.4.5

实验验证成功.
