Linux 中搭建DHCP服务器实例

1、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

2、㈠ 首先查看dhcp服务是否安装[plain] view plaincopyprint?1. [root@localhost ~]# rpm -qa | grep dhcp2. dhcp-3.0.5-31.el53. dhcpv6-client-1.0.10-20.el54. sblim-cmpi-dhcp-devel-1.0-49.el55. sblim-cmpi-dhcp-1.0-49.el5

3、㈡ 编辑/etc/dhcpd.con酆璁冻嘌f[plain] view plaincopyprint?1. [root刺胳挤萧@localhost ~]# cat /etc/dhcpd.conf2. #3. # DHCP Server Configuration file.4. # see /usr/share/doc/dhcp*/dhcpd.conf.sample5. 6. [root@localhost ~]# cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf7. cp：是否覆盖“/etc/dhcpd.conf”? yes8. 9. [root@localhost ~]# cat /etc/dhcpd.conf10. 11. ddns-update-style interim; #DDNS更新方式，这里的设定值有3种：ad-hoc、interim和none12. ignore client-updates; #忽略客户端更新13. 14. subnet 192.168.1.0 netmask 255.255.255.0 {15. 16. option routers 192.168.1.1; #网关地址设定17. option subnet-mask 255.255.255.0; #子网掩码设定18. option domain-name "localdomain"; #主机域名19. option domain-name-servers 192.168.1.110; #设定DNS服务器地址20. range dynamic-bootp 192.168.1.128 192.168.1.136; #动态分配的IP地址范围21. }

4、㈢ 对网卡绑定DHCP服务[plain] view plaincopyprint?1. [root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth02. # Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]3. DEVICE=eth04. BOOTPROTO=dhcp5. ONBOOT=yes

5、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

6、㈤ 验证[plain] view plaincopyprint?1. [root@localhost ~]# ifconfig eth02. eth0 Link encap:Ethernet HWaddr 00:0C:29:F9:B7:FA3. inet addr:192.168.227.131 Bcast:192.168.227.255 Mask:255.255.255.04. inet6 addr: fe80::20c:29ff:fef9:b7fa/64 Scope:Link
