CentOS安裝DHCP配置命令

1、Cent OS 5.5 DHCP服務(wù)器配置命令環(huán)境：OS： CentOS 5.5 i386RPM 包：dhcp-3.0.5-23.el5.i386.rpm首先檢查DHCP服務(wù)是否安裝：rootlocalhost /# rpm -q dhcppackage dhcp is not installed將光盤放入光驅(qū)，通過mount命令進(jìn)行掛載。rootlocalhost /# mount /dev/cdrom /mntmount: block device /dev/cdrom is write-protected, mounting read-onlyrootlocalhost /# cd /m

2、nt/CentOS/rootlocalhost CentOS# ls | grep dhcp 查看關(guān)鍵字 “dhcp文件dhcp-3.0.5-23.el5.i386.rpmdhcp-devel-3.0.5-23.el5.i386.rpmdhcpv6-1.0.10-18.el5.i386.rpmdhcpv6-client-1.0.10-18.el5.i386.rpmlibdhcp-1.20-10.el5.i386.rpmlibdhcp4client-3.0.5-23.el5.i386.rpmlibdhcp4client-devel-3.0.5-23.el5.i386.rpmlibdhcp6cli

3、ent-1.0.10-18.el5.i386.rpmlibdhcp6client-devel-1.0.10-18.el5.i386.rpmlibdhcp-devel-1.20-10.el5.i386.rpmsblim-cmpi-dhcp-1.0-40.el5.i386.rpmsblim-cmpi-dhcp-devel-1.0-40.el5.i386.rpmsblim-cmpi-dhcp-test-1.0-40.el5.i386.rpm注解dhcp-*DHCP服務(wù)器軟件包dhclient-*DHCP客戶機(jī)軟件包dhcp-devel-*DHCP開發(fā)工具，非必需在這個目錄下有DHCP的安裝包，使用r

4、pm命令進(jìn)行安裝。rootlocalhost CentOS# rpm -ivh dhcp-3.0.5-23.el5.i386.rpmwarning: dhcp-3.0.5-21.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897Preparing.# 100%1:dhcp#100%安裝完之后檢查是否安裝到機(jī)器上。rootlocalhost CentOS# rpm -q dhcpdhcp-3.0.5-21.el5在安裝目錄下有一個模板(/usr/share/doc/dhcp-3.05/dhcpd.conf.sample)，通

5、過 CP命令進(jìn)行覆蓋。rootlocalhost CentOS# cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample/etc/dhcpd.confcp：是否覆蓋 “/etc/dhcpd.cory”？通過vi進(jìn)入dhcpd.conf配置文件進(jìn)行配置rootlocalhost CentOS# vim /etc/dhcpd.conf1.ddns-update-style interim;#配置使用過渡性DHCP-DNS互動更新模式。2.ignore client-updates;#忽略客戶端更新3.4.5.subnet 192.168.0.0 netmask

6、 255.255.255.0 (6.7.optionrouters;#路由器地址8.optionsubnet-mask;#子網(wǎng)掩碼選項9.10.optionnis-domain;11.optiondomain-name;#域名12.optiondomain-name-servers6，33；#DNS地址13.14.optiontime-offset-18000; # EasternStandard Time15.16.range dynamic-bootp 00 00;#租用IP地址的范圍17.default-lease-time 21600;#缺省租約時間18.max-lease-time

7、43200;#最大租約時間19.20.# we want the nameserver to appear at a fixed address21.host ns (22.next-server ;23.hardware ethernet12:34:56:78:AB:CD;24.fixed-address207.175.42.254;25.26.設(shè)置完成，DHCP服務(wù)就搭建好了，啟動服務(wù)即可。rootDHCPserver CentOS# /etc/init.d/dhcpd startlinux客戶端：修改ifcfg-eth0的文件，將BOOTPROTO選項改為DHCP,自動獲取。rootlocalhost # vim /etc/sysconfig/network-scripts/ifcfg-eth0# Advanced Micro Devices AMD 79c970 PCnet32 LANCEDEVICE=eth0BOOTPROTO=dhcpHWADDR=00:0C:29:D1:8D:
