Linux DHCP服务器搭建
1. 需要做的准备工作:
Dhcp服务器的安装
两台虚拟机:一台红帽,做dhcp服务器;另一台window2003,动态获得ip地址。
2. dhcp的配置:
注:以下红色为要编写内容。
(1)在服务器上设置一个ip地址,比如192.168.5.100.
# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0c:29:39:65:80
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.5.100
TYPE=Ethernet
GATEWAY=192.168.5.254
(2) 编辑 /etc/dhcpd.conf文件来编写dhcp地址池:
subnet 192.168.5.0 netmask 255.255.255.0 {
# --- default gateway
option routers 192.168.5.254;
option subnet-mask 255.255.255.0;
option domain-name "xiaoyangdabian.com";
option domain-name-servers 222.88.88.88,222.85.85.85;(dns,这个是根据自己的情况)
option time-offset -18000; # Eastern Standard Time
# option ntp-servers 192.168.1.1;
# option netbios-name-servers 192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
# option netbios-node-type 2;
range dynamic-bootp 192.168.5.1 192.168.5.253;
default-lease-time 21600;
max-lease-time 43200;
(3)启动dhcp服务器:
# service dhcpd start | restart
3. 打开window2003虚拟机,将本地连接设置为自动获取ip地址,然后输入 ipconfig/renew 查看 获取ip地址的情况
