編寫安裝配置DHCP服務腳本

要求：

1、自動完成安裝，基本配置

2、通過提示輸入網段、子網路遮罩、網關、DNS、IP起止位址等資訊完成作用域的添加

【方法一】：

#!/bin/bash

conf="/etc/dhcpd.conf"

rpm -q dhcp &> /dev/null

if [ $? -ne 0 ];then

yum -y install dhcp

fi

grep "subnet" $conf &> /dev/null

if [ $? -ne 0 ]; then

echo "

ddns-update-style interim;

ignore client-updates;

default-lease-time 21600;

max-lease-time 43200;

" > $conf

read -p "please input network:" network

read -p "please input netmask:" netmask

read -p "please input gateway:" gateway

read -p "please input DNS:" dns

read -p "please input start_ip:" start_ip

read -p "please input end_ip:" end_ip

subnet $network netmask $netmask {

       option routers                  $gateway;

option subnet-mask              $netmask;

       option domain-name-servers      $dns;

       range dynamic-bootp $start_ip $end_ip;

}

" >> $conf

service dhcpd restart

【方法二】：

dhcpconf=/etc/dhcpd.conf

grep "subnet" $dhcpconf  &> /dev/null

echo "ddns-update-style interim;

max-lease-time 43200;" > $dhcpconf

while true

do

read -p "please input Network:" network

read -p "please input Netmask:" netmask

read -p "please input Gateway:" gateway

read -p "please input Start_IP:" start_ip

read -p "please input End_IP:" end_ip

grep $network $dhcpconf &> /dev/null

echo "subnet $network netmask $netmask {

option routers                  $gateway;

       option subnet-mask              $netmask;

option domain-name-servers      $dns;

range dynamic-bootp $start_ip $end_ip;

}" >> $dhcpconf

read -p "continue to do (yes/no)?" yn

if [ $yn = "no" ]; then

service dhcpd status &> /dev/null

service dhcpd start &> /dev/null

else

service dhcpd reload &> /dev/null

exit 0

done
