DHCP伺服器

1、安裝DHCP伺服器元件：

#yum -y install dhcp

2、配置DHCP：

DHCP配置檔案為/etc/dhcpd/dhcpd.conf，但該檔案預設是沒有内容的，是以需要手動添加

Subnet: 192.168.1.0/24

Gateway (Router IP Address): 192.168.1.1

DNS IP:  222.34.19.99,222.34.29.98

range：192.168.1.100 192.168.1.254

如果配置檔案錯誤， DHCP服務啟動失敗， 不提示錯誤， 是以很難找到原因，但是/var/log/messages 裡有記錄

以下是我的完整配置檔案，可以用來參考

# DHCP Server Configuration file.

#   see /usr/share/doc/dhcp*/dhcpd.conf.sample

#   see 'man 5 dhcpd.conf'

#

# This DHCP server to be declared valid

authoritative;

# Subnet 192.168.1.0/24

subnet 192.168.1.0 netmask 255.255.255.0 {

# default gateway

option routers 192.168.1.1;

# domain name

option domain-name "test.com";

# DNS's hostname or IP address

option domain-name-servers 222.34.19.99,222.34.29.98;

# range of lease IP address

range dynamic-bootp 192.168.1.100 192.168.1.254;

# default lease time

default-lease-time 600;

# max lease time

max-lease-time 7200;

# broadcast address

option broadcast-address 192.168.1.255;

#####   Reserved Hosts   #####

# Router

host router {

 hardware ethernet 20:DC:E6:72:B8:A2;

 fixed-address 192.168.1.1;

 }

} # end of Subnet 192.168.1.0/24

3.設定監聽端口

# /etc/sysconfig/dhcp

DHCPDARGS="eth0"  

4.啟動服務

# /etc/rc.d/init.d/dhcpd start
