DHCP服務器配置：
找到dhcp-3.0.5-7.el5.i386.rpm 這個包，然後安裝。
安裝 rpm -ivh foo-1.0-l.i386.rpm i表示includedocs 安裝文檔，V表示顯示附加信息，h表示hash 安裝時輸出hash 記號。
[root@test Server]# rpm -ivh dhcp-3.0.5-21.el5.i386.rpm
warning: dhcp-3.0.5-21.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

表示安裝成功。
安裝成功後會生成以下兩個文件
配置文件是/etc/dhcpd.conf , 租約數據庫文件時 /var/lib/dhcpd/dhcpd.leases ,
然後，編輯 /etc/dhcpd.conf ,
[root@test dhcpd]# vi /etc/dhcpd.conf
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample 其中會顯示這兩行
接下來，我們要將/usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample 覆蓋到/etc/dhcp.conf
[root@test dhcp-3.0.5]# cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf
cp：是否覆蓋“/etc/dhcpd.conf”? y
然後編輯/etc/dhcpd.conf 文件：
[root@test etc]# vi dhcpd.conf
ddns-update-style interim; #定義所支持的DNS動態更新類型
ignore client-updates; #忽略客戶端更新
subnet 192.168.0.0 netmask 255.255.255.0 {
# --- default gateway
option routers 192.168.0.1; #網關地址
option subnet-mask 255.255.255.0; #子網掩碼：默認子網掩碼
option nis-domain "domain.org";
option domain-name "domain.org"; #DNS後綴
option domain-name-servers 192.168.1.1; #DNS服務器地址
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 192.168.0.128 192.168.0.254; #動態IP地址範圍
default-lease-time 21600; #默認IP租約時間，單位秒
max-lease-time 43200; #客戶端IP租約時間最大值，單位爲妙
# 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;
}
}
可以修改爲：
ddns-update-style interim; #定義所支持的DNS動態更新類型
ignore client-updates; #忽略客戶端更新
subnet 192.168.100.0 netmask 255.255.255.0 {
# --- default gateway
option routers 192.168.100.1; #網關地址
option subnet-mask 255.255.255.0; #子網掩碼：默認子網掩碼
option nis-domain "yanglei.com";
option domain-name "yanglei.com"; #DNS後綴
option domain-name-servers 192.168.100.1; #DNS服務器地址
option time-offset -18000; # Eastern Standard Time
# option ntp-servers 192.168.100.1;
# option netbios-name-servers 192.168.100.1;
# --- 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 192.168.100.10 192.168.100.254; #動態IP地址範圍
default-lease-time 21600; #默認IP租約時間，單位秒
max-lease-time 43200; #客戶端IP租約時間最大值，單位爲妙
# 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;
}
}
修改完後保存。
