LINUX DHCP輕巧，也比較簡單
1.安裝：
[root@localhost dhcp]# rpm -q dhcp //查詢是否安裝
dhcp-3.0.5-21.el5
[root@localhost dhcp]# rpm -ivh dhcp-3.0.5-21.el5.x86_64.rpm //安裝DHCP
2.dhcp配置文件
默認爲/etc/dhcpd.conf
例子文件爲:/usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample:
[root@localhost dhcp-3.0.5]# more dhcpd.conf.sample
ddns-update-style interim;
ignore client-updates;
subnet 192.168.0.0 netmask 255.255.255.0 { //如果非relay方式,這個subnet一定要包括server的本地IP的在內.否則服務啓動不了.
# --- default gateway
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;
option nis-domain "domain.org";
option domain-name "domain.org";
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 192.168.0.128 192.168.0.254;
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;
}
}
可將該文件複製到/etc/dhcpd.conf，然後進行修改
3.中繼
dhcrelay *.*.*.*
或者編輯/etc/sysconfig/dhcrelay配置文件
4.服務啓停
/etc/init.d/dhcpd start
/etc/init.d/dhcpd stop
/etc/init.d/dhcpd restart
/etc/init.d/dhcpd status //查看服務狀態
或者 services dhcpd restart
5.ntsysv將DHCP設置爲開機啓動
6.服務器日誌從/var/log/messages中查到，租賃信息也可從這裏查到
7.租約信息從/var/lib/dhcp/dhcpd.leases看到
8.如果測試Linux客戶端是否可以獲取地址，則編輯/etc/sysconfig/network-scripts/ifcfg-eth0
BTTOPROTO=dhcp
