RHEL5 下简单的dhcp搭建

 # rpm -ivh dhcp-3.0.5-21.el5.i386.rpm

安装dhcp软件包

# cat /etc/dhcpd.conf

#

# DHCP Server Configuration file.

#   see /usr/share/doc/dhcp*/dhcpd.conf.sample

显示配置文件范本的存放位置

 

# cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf

cp:是否覆盖“/etc/dhcpd.conf”? y

输入y

 

# vim /etc/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

subnet 192.168.1.0 netmask 255.255.255.0 {

表示要动态分配那个网段的

        option routers                  192.168.1.254;

默认网关

        option subnet-mask              255.255.255.0;

使用的子网掩码是

        option domain-name              "crazy.hn";

网内主机的域名是

        option domain-name-servers      192.168.1.1;

DNS服务器的IP

        option time-offset              -18000; # Eastern Standard Time

        range dynamic-bootp 192.168.1.128 192.168.1.218;

分配IP地址的范围

        default-lease-time 21600;

        max-lease-time 43200;

默认和最大的租期世界单位秒

        host ns {

固定分配IP

                hardware ethernet 12:34:56:78:AB:CD;

客户机的MAC地址

                fixed-address 207.175.42.254;

IP地址

        }

}

：wq

保存退出

service dhcpd start

开启服务

Starting dhcpd:                                                  [OK]

 

# netstat -anpu | grep dhcp

查看服务是否在UDP协议的67端口

udp00 0.0.0.0:670.0.0.0:*3936/dhcpd
