debian5中安装dhcp服务器的简明过程

1、修改IP和dns
[root@dhcp]# vim /etc/network/interfaces
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet static
address *.*.*.*
netmask 255.255.255.0
network *.*.*.*.0
broadcast *.*.*.255
gateway *.*.*.1
dns-nameservers 8.8.8.8
[root@dhcp]# vim /etc/resolv.conf
nameserver 8.8.8.8
2、更新apt包
[root@dhcp]# apt-get update
3、安装open ssh server (方便远程管理)
[root@dhcp]# apt-get install openssh-server
4、安装dhcp3-server
[root@dhcp]# apt-get install dhcp3-server
5、修改dhcp配置文档
[root@dhcp]# vim /etc/dhcp3/dhcpd.conf
#――-开始
authoritative;
ddns-update-style interim;
#ignore client-updates;
# 注释
subnet 192.168.1.0 netmask 255.255.255.0{
option routers                             192.168.1.1;
option subnet-mask                    255.255.255.0;
option nis-domain                      “***.edu.cn”;
option domain-name                  “***.edu.cn”;
option domain-name-servers    8.8.8.8,8.8.8.4;
option time-offset                     -18000;
range dynamic-bootp                192.168.1.2 192.168.1.190;
default-lease-time                    21600;
max-lease-time                        43200;
}
………  #省略其他网段
#―-结束
6、重启dhdp服务,如有问题,可查看/var/log/syslog以及 /var/log/messages,查找故障原因。
[root@dhcp]# /etc/init.d/dhcp3-server start
查看dhcp客户端获取地址的记录:
[root@dhcp]# vim /var/lib/dhcp3/dhcpd.leases
7、修改三层交换机配置,将该服务器设为dhcp server。
其他:
a.   debian移除软件包:apt-get remove package
b.   修改debian源: vim /etc/apt/sources.list
