AS4下配置dhcp 操作系統:Red Hat Enterprise Linux AS release 4 (Nahant Update 3)2.6.9-34.EL
Redhat使用dhcpd進程提供DHCP服務,啟動時dhcpd自動讀它的配置文件/etc/dhcpd.conf.dhcpd將客戶的租用信息保存
在/var/lib/dhcp/dhcpd.leases文件中,該文件不斷被更新,從這裡面可以查到IP地址分配的情況.
配置實例:
--------------------------------------------------
# rpm -qa | grep dhcp
dhcp-3.0pl1-23
# ls /etc/dhcpd.conf
# find /usr/share/doc -name dhcp*.*
/usr/share/doc/dhcp-3.0pl1
/usr/share/doc/dhcp-3.0pl1/dhcpd.conf.sample
# cp /usr/share/doc/dhcp-3.0pl1/dhcpd.conf.sample /etc/dhcpd.conf
----------------------------------------------------------------------
# vi /etc/dhcpd.conf ----------編輯dhcpd.conf文件
ddns-update-style interim; #定義所支持的DNS動態更新的型{none|adhoc|interim}
ignore client-updates; #allow/ignore允許/忽略客戶機更新DNS記錄
subnet 192.168.0.0 netmask 255.255.255.0{
#定義dhcp服務的子網
default-lease-time 21600;
#默認的租約時間,單位為秒
max-lease-time 518400;
#最長時間518400秒
option domain-name-servers 192.168.0.5;
#定義dns地址
option routers 192.168.0.1;
#定義默認路由
range dynamic-bootp 192.168.0.10 192.168.0.253;
#定義給客戶端分配的IP地址範圍
option subnet-mask 255.255.255.0;
#定義分配的子網掩碼
option broadcast-address 192.168.0.255;
#定義廣播地址
host ns {
next-server marvin.redhat.com;
hardware ethernet 00:0C:29:BE:63:32;
fixed-address 192.168.0.100;
option broadcast-address 192.168.0.255;
option routers 192.168.0.3;
} #靜態IP地址分配,mac地址為63:32的網卡分配192.168.0.100這個地址
[root@apple ~]# /etc/rc.d/init.d/dhcpd start
#啟動dhcp服務,配置完比,可去客戶端做測試
