Shell脚本——DHCP自动部署

详细说明参考：

（三）跟我一起玩Linux网络服务：DHCP服务配置之主服务器配置

 #! /bin/bash
 IPSAG="10.10.10"
 DNSIP="10.10.10.10"
 DN="ns.gr.org"
 cat  >  /etc/dhcpd.conf << +END+
 ddns-update-style interim;
 ignore client-updates;
 subnet $IPSAG. netmask 255.255.255.0 {
         option routers                  $DNSIP;
         option subnet-mask              255.255.255.0;
         option domain-name              "$DN";
         option domain-name-servers      $DNSIP;
         option time-offset              ;
         range dynamic-bootp $IPSAG. $IPSAG.;
         default-lease-time ;
         max-lease-time ;
         host boss {
                 next-server marvin.redhat.com;
                 hardware ethernet ::::AB:CD;
                 fixed-address 207.175.42.188;
         }
 }
 +END+
 service dhcpd restart
 ps -ax | grep dhcpd
