Linux架构DHCP服务器

毕业论文（设计）第1页共27页Linux架构DHCP服务器摘要随着互联网的普及，人们的工作，学习和生活与网络联系越来越紧密，搭建了许多不同的网络，如企业网，校园网和城区网等。网络管理是大型计算机网络成功的关键因素，利用DHCP服务已经显得相当流行。动态主机分配协议（DHCP）的运用也显得越来越重要。在实际的操作过程中，构建DHCP服务器也越来越常见。而采用DHCP技术动态地为主机极大地减轻大型网络管理员的工作量，减少手工网络配置的错误，有利于快速地搭建一个大型网络或修改其网络配置。构建DHCP服务器需要一个稳定的操作系统和服务器软件。在操作系统的竞争之中，Linux以“免费，高效，稳定，跨平台”的特点，加上功能强大，对硬件配置需求低等优势，迅速地占领了一些其他商业操作系统市场，而且还在持续蔓延和发展。而RedhatLinux操作系统经过一段时间的发展已经成为一个主要的Linux发行版本，越来越多的企业和个人开始采用它来进行工作、学习和娱乐。同时，RedhatLinux中附带的DHCP服务也是目前Internet上最上欢迎的动态IP地址分配服务器。本文以企业网的DHCP服务器为基础，一步步地描述DHCP服务器的构建过程。关键词：企业网，Linux，DHCP毕业论文（设计）第2页共27页LinuxframeworkaDHCPserverAuthor：Tutor：AbstractWiththepopularityoftheInternet,people'swork,studyandlivingincreasinglyclosetieswiththenetwork,setupanumberofdifferentnetworks,suchasenterprisenetworks,campusnetworksandurbannetworks,etc..Networkmanagementisalargecomputernetworks,akeyfactorinthesuccessoftheuseofDHCPservicehasbecomeverypopular.DynamicHostAllocationProtocol(DHCP)usehasbecomeincreasinglyimportant.Intheactualoperation,buildingaDHCPserverisalsobecomingmorecommon.TechnologicaldevelopmentsandtheuseofDHCPforhostconfigurationparameters,caneffectivelyaddressthecurrentshortageofIPaddressresourcesandusermobilityissues,andcangreatlyreducetheworkloadofalargenetworkadministratorstoreduceerrorsinmanualnetworkconfigurationisconducivetorapidtobuildalargenetworkormodifytheirnetworkconfiguration.DHCPserverneedstobuildastableoperatingsystemandserversoftware.Amongthecompetitionintheoperatingsystem,Linuxinordertofree,highefficiency,stability,cross-platformfeatures,combinedwithpowerfuladvantagesoflowhardwarerequirementsandquicklyoccupiedanumberofothercommercialoperatingsystemmarket,butalsoalsocontinuedtospreadanddevelopment.TheRedhatLinuxoperatingsystem,afteraperiodofdevelopmenthasbecomeamajorLinuxdistribution,moreandmorebusinessesandindividualsbegantouseitforwork,studyandrecreation.Atthesametime,RedHatLinuxforDHCPservicesarealsoincludedinthecurrentInternet,themostpopulardynamicIPaddressallocationserver.Inthispaper,enterprisenetworkDHCPserver,basedonastepbystepdescriptionoftheDHCPserverbuildprocess.Keywords:Enterprisenetworks，Linux，DHCP毕业论文（设计）第3页共27页目录1DHCP服务概述..................................................................................................................................................41.1DHCP的概述...............................................................................................................................................41.2DHCP分配地址的方式...............................................................................................................................41.3DHCP的工作过程.......................................................................................................................................51.4DHCP的作用...............................................................................................................................................82DHCP服务器的搭建.....................................................................................................................................92.1安装DHCP服务器......................................................................................................................................92.2DHCP服务器配置文件介绍......................................................................................................................102.3应用实例....................................................................................................................................................152.4启动和检查DHCP服务器........................................................................................................................162.5配置DHCP客户端....................................................................................................................................172.5.1Linux客户端配置...............................................................................................................................172.5.2Windows客户端配置..........................................................................................................................203管理和维护DHCP服务器............................................................................................................................213.1DHCP服务器常见故障排除......................................................................................................................213.2DHCP服务器的安全.................................................................................................................................244DHCP的优缺点.............................................................................................................................................254.1DHCP的优点.............................................................................................................................................254.2DHCP的缺点.............................................................................................................................................25结束语.................................................................................................
