DHCP 服务器的配置过程

DHCP 服务器的配置过程

[b][b][b][b][b]以前在做实验的过程中总结和写的一些教程的一些资料，一直没时间发布到博客上面，五一到了，终于有点时间发布啦！关于Linux上面还会有RHCE系列的学习笔记发表[/b][/b][/b][/b]

[/b]DHCP的安装包是：dhcp-3.0.1-12_EL.i386.rpm

守护进程是：dchpd

服务器的配置过程：

1、安装 rpm包

[root@cisco ~]# cd /media/cdrom/RedHat/RPMS/

[root@cisco RPMS]# rpm -ivh dhcp-3.0.1-12_EL.i386.rpm

warning: dhcp-3.0.1-12_EL.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e

Preparing... ########################################### [100%]

package dhcp-3.0.1-12_EL is already installed

[root@cisco RPMS]#

2、复制配置文件的样本：

[root@cisco RPMS]# cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf

3、编辑配置文件：

[root@cisco RPMS]# vi /etc/dhcpd.conf

subnet 192.168.20.0 netmask 255.255.255.0 {

# --- default gateway

option routers 192.168.20.1;

option subnet-mask 255.255.255.0;

option nis-domain "domain.org";

option domain-name "benet.com";

option domain-name-servers 192.168.1.1;

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 192.168.20.100 192.168.20.200;

default-lease-time 21600;

max-lease-time 43200;

# we want the nameserver to appear at a fixed address

host ns {

next-server marvin.redhat.com;

hardware ethernet 12:34:56:78:AB:CD;

fixed-address 207.175.42.254;

}

}

[root@cisco ~]# service dhcpd start

5、多网卡配置选择的配置文件

[root@cisco ~]# cat /etc/sysconfig/dhcpd

# Command line options here

DHCPDARGS= 这里添网卡即可

6、租约文件：

[root@cisco ~]# cat /var/lib/dhcp/dhcpd.leases

# All times in this file are in UTC (GMT), not your local timezone. This is

# not a bug, so please don't ask about it. There is no portable way to

# store leases in the local timezone, so please don't request this as a

# feature. If this is inconvenient or confusing to you, we sincerely

# apologize. Seriously, though - don't ask.

# The format of this file is documented in the dhcpd.leases(5) manual page.

# This lease file was written by isc-dhcp-V3.0.1

lease 192.168.20.200 {

starts 5 2009/05/29 05:16:44;

ends 5 2009/05/29 11:16:44;

tstp 5 2009/05/29 11:16:44;

binding state active;

next binding state free;

hardware ethernet 00:0c:29:00:77:3e;

}

DHCP 客户端的配置

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=dhcp

IPADDR=192.168.20.10

NETMASK=255.255.255.0

GATEWAY=192.168.1.254

[root@localhost ~]# ifconfig eth0

eth0 Link encap:Ethernet HWaddr 00:0C:29:00:77:3E

inet addr:192.168.20.200 Bcast:192.168.20.255 Mask:255.255.255.0
