RHEL5 下簡單的dhcp搭建

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

安裝dhcp軟件包

# cat /etc/dhcpd.conf

#

# DHCP Server Configuration file.

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

顯示配置文件範本的存放位置

 

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

cp:是否覆蓋「/etc/dhcpd.conf」? y

輸入y

 

# vim /etc/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

subnet 192.168.1.0 netmask 255.255.255.0 {

表示要動態分配那個網段的

        option routers                  192.168.1.254;

默認網關

        option subnet-mask              255.255.255.0;

使用的子網掩碼是

        option domain-name              "crazy.hn";

網內主機的域名是

        option domain-name-servers      192.168.1.1;

DNS服務器的IP

        option time-offset              -18000; # Eastern Standard Time

        range dynamic-bootp 192.168.1.128 192.168.1.218;

分配IP地址的範圍

        default-lease-time 21600;

        max-lease-time 43200;

默認和最大的租期世界單位秒

        host ns {

固定分配IP

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

客戶機的MAC地址

                fixed-address 207.175.42.254;

IP地址

        }

}

：wq

保存退出

service dhcpd start

開啓服務

Starting dhcpd:                                                  [OK]

 

# netstat -anpu | grep dhcp

查看服務是否在UDP協議的67端口

udp00 0.0.0.0:670.0.0.0:*3936/dhcpd
