Linux 中搭—HCP服务器实例

下面的流程实例中，DHCP服务分配的IP地址段为192.168.1.128~192.168.1.133

㈠ 首先查看dhcp服务是否安装

[root@localhost ~]# rpm -qa | grep dhcpdhcp-3.0.5-31.el5dhcpv6-client-1.0.10-20.el5sblim-cmpi-dhcp-devel-1.0-49.el5sblim-cmpi-dhcp-1.0-49.el5

㈡ 编辑/etc/dhcpd.conf

[root@localhost ~]# cat /etc/dhcpd.conf## DHCP Server Configuration file.#   see /usr/share/doc/dhcp*/dhcpd.conf.sample [root@localhost ~]# cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.confcp：是否覆盖“/etc/dhcpd.conf”? yes[root@localhost ~]# cat /etc/dhcpd.confddns-update-style interim;  #DDNS更新方式，这里的设定值有3种：ad-hoc、interim和noneignore client-updates;  #忽略客户端更新subnet 192.168.1.0 netmask 255.255.255.0 {        option routers                  192.168.1.1;   #网关地址设定        option subnet-mask              255.255.255.0; #子网掩码设定        option domain-name              "localdomain"; #主机域名        option domain-name-servers      192.168.1.110; #设—NS服务器地址        range dynamic-bootp 192.168.1.128 192.168.1.136; #动态分配的IP地址范围}

㈢ 对网卡绑—HCP服务

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]DEVICE=eth0BOOTPROTO=dhcpONBOOT=yes

㈣ 重新启动DHCP服务

DHCP服务使用UDP的67端口，但Iptables不能过滤DHCP服务使用的原始套接字（Raw Socket）
所以在服务设定好之后，无须再设定Iptables
service dhcpd start
service network restart
如果在虚拟机内搭建，记得把网卡模式改成NAT

㈤ 验证

[root@localhost ~]# ifconfig eth0eth0      Link encap:Ethernet  HWaddr 00:0C:29:F9:B7:FA            inet addr:192.168.227.131  Bcast:192.168.227.255  Mask:255.255.255.0          inet6 addr: fe80::20c:29ff:fef9:b7fa/64 Scope:Link
