DHCP的配置文檔

標籤：linux   file   

1、配置YUM

vim /etc/yum.repos.d/rhel-debuginfo.repo

[rhel-debuginfo]

name=Red Hat Enterprise Linux $releasever - $basearch - Debug

baseurl=file:///misc/cd/Server

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

2、配置IP

vim /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

HWADDR=00:0C:29:FC:E2:45

ONBOOT=yes

IPADDR=192.168.100.1

NETMASK=255.255.255.0

vim /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1

BOOTPROTO=none

HWADDR=12:34:56:78:90：ab

ONBOOT=yes

IPADDR=192.168.200.1

NETMASK=255.255.255.0

service network restart

3、安裝、配置DHCP服務

yum install dhcp -y

cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf

vim /etc/dhcpd.conf

＃全域配置

ddns-update-style none;  #動態DNS更新方法

ignore client-updates;     ＃忽略客戶機更新

＃子網配置

#誰寫IP誰傻X

subnet 192.168.100.0 netmask 255.255.255.0 {

＃分配IP位址集區、子網路遮罩、網關、DNS

        range dynamic-bootp 192.168.100.128 192.168.100.254;

        option subnet-mask              255.255.255.0;

        option routers                  192.168.100.1;

        option domain-name              "benet.com";

        option domain-name-servers      192.168.100.1,192.168.100.2;

#租約時間:最大時間，更新時間

        default-lease-time 21600;

        max-lease-time 43200;

＃主機配置（相當於WINDOWS裡的保留）

        host ns {

                #next-server marvin.redhat.com;

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

                #fixed-address 207.175.42.254;

        }

subnet 192.168.200.0 netmask 255.255.255.0 {

        range dynamic-bootp 192.168.200.128 192.168.200.254;

        option subnet-mask              255.255.255.0;

        option routers                  192.168.200.1;

        option domain-name              "benet.com";

        option domain-name-servers      192.168.200.1,192.168.200.2;

        default-lease-time 21600;

        max-lease-time 43200;

        host ftp {

                hardware ethernet 00:0C:29:60:E4:AD;

                fixed-address 192.168.200.10;

        }

        host web {

                hardware ethernet 12:34:56:78:90:AB;

                fixed-address 192.168.200.20;

        }

}

service dhcpd start

chkconfig dhcpd on

4、補充：

限制dhcp伺服器提供服務的網路介面

vim  /etc/sysconfig/dhcpd

DHCPDARGS="eth0 eth1"

租約檔案

tail -f /var/lib/dhcpd/dhcpd.leases
