DHCP配置步骤

Server的配置

1.netconfig  //配置服务器端IP
  service ntework restart 
2.mount /dev/cdrom   //安装dhcp所需软件
  rpm -ivh dhcp-3………
  rpm -ivh dhcp-d………
  umount /dev/cdrom
3.vi /etc/dhcpd.conf  //配置dhcp服务器配置文件(默认文件不存在，需手工建立)
  cp /usr/share/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf
  vi /etc/dhcpd.conf
4.service dhcpd restart  //启动dhcp服务
  service dhcpd status

Client的配置

Windows: ipconfig /release   //释放IP
         ipconfig /renew   //重新获取IP
         ipconfig   //查看IP
Linux:   netconfig  //设置IP为动态获取
         service network restart

Server信息查看
tail /var/lib/dhcp/dhcpd.leases   //查看租约文件内容

Server的配置②(给指定主机分配固定IP)
1.vi /etc/dhcpd.conf  //配置host声明文件
  /etc/rc.d/init.d/dhcpd restart
