Shell脚本——中继DHCP服务器自动部署

详细说明参照：

（四）跟我一起玩Linux网络服务：DHCP服务配置之中继代理

 

vm1的脚本是：

 

 1 #! /bin/bash

 2 

 3 HIPSEG="10.10.10"

 4 SIPSEG="192.168.128"

 5 HRoute="10.10.10.10"

 6 SRoute="192.168.128.8"

 7 DN="ns.gr.org" 

 8 

 9 cat  > /etc/dhcpd.conf << +END+

10 ddns-update-style interim;

11 ignore client-updates;

12 

13 subnet $HIPSEG.0 netmask 255.255.255.0 {

14         option routers                  $HRoute;

15         option subnet-mask              255.255.255.0;

16         option domain-name              "$DN";

17         option domain-name-servers      $HRoute;

18         option time-offset              28800;

19         range dynamic-bootp $HIPSEG.100 $HIPSEG.200;

20         default-lease-time 21600;

21         max-lease-time 43200;

22 }

23 subnet $SIPSEG.0 netmask 255.255.255.0 {

24         option routers                  $SRoute;

25         option subnet-mask              255.255.255.0;

26         option domain-name              "$DN";

27         option domain-name-servers      $HRoute;

28         option time-offset              28800;

29         range dynamic-bootp $SIPSEG.100 $SIPSEG.200;

30         default-lease-time 21600;

31         max-lease-time 43200;

32 }

33 +END+

34 service dhcpd restart

35 ps -ax | grep dhcpd

36 

37 route add -net $SIPSEG.0/24 gw $HRoute

 

vm2的脚本是：
