部署PXE实现Kickstart无人值守安装

部署PXE实现Kickstart无人值守安装

部署PXE实现Kickstart⽆⼈值守安装⼀、部署PXE远程安装服务1.PXE服务相关介绍PXE是有Intel公司开发的⽹络引导技术,⼯作在Client/Server模式(也简称CS模式),允许客户机通过⽹络从远程服务器下载引导镜像,并加载安装⽂件或整改操作系统。

2..若要搭建PXE⽹络体系,必须要满⾜⼀下⼏个前提条件客户机的⽹卡⽀持PXE协议(集成BOOTROM芯⽚),且主板⽀持⽹络引导;⽹络中有⼀台DHCP服务器以便于为客户机⾃动分配IP地址、指定引导⽂件位置;服务器通过TFTP(简单⽂件传输协议)提供引导镜像⽂件的下载3.PXE服务具备的优点规模化:同时装配多台服务器,⽆需每⼀台单独安装操作系统;⾃动化:实现服务器的⾃动安装及⾃动配置各种服务;远程实现:不需要光盘、U盘等安装介质,⽅便快捷的同时⼜可以保障服务器安全。

4.PXE服务的⼯作原理PXE(Pre-boot Execution Environment远程引导技术)是RPL (Remote Initial Program Load远程启动服务)的升级产品。

它们的不同之处为: RPL是静态路由,PXE是动态路由。

RPL 是根据⽹卡上的ID号加上其它的记录组成的⼀个帧向服务器发出请求,⽽服务器那⾥早已经有了这个ID数据,匹配成功则进⾏远程启动;PXE则是根据服务器端收到的⼯作站MAC地址(就是⽹卡号)使⽤DHCP服务给这个MAC地址指定⼀个IP地址,每次重启动可能同⼀台⼯作站有与上次启动有不同的IP,即动态分配地址以⼯作站引导过程说明PXE的原理:⼯作站开机后,PXEBootROM(⾃启动芯⽚)获得控制权之前先做⾃我测试,然后以⼴播形式发出⼀个请求FIND帧。

如果服务器收到⼯作站所送出的要求,就会送回DHCP回应,内容包括⽤户端的IP地址,预设通讯通道,及开机映像⽂件。

否则,服务器会忽略这个要求。

⼯作站收到服务器发回的相应后则会回应⼀个帧,以请求传送启动所需⽂件。

Kickstart文件详解

Kickstart⽂件详解1、ks.cfg⽂件介绍:ks.cfg⽂件组成⼤致分为3段命令段键盘类型,语⾔,安装⽅式等系统的配置,有必选项和可选项,如果缺少某项必选项,安装时会中断并提⽰⽤户选择此项的选项软件包段 %packages @groupname:指定安装的包组 package_name:指定安装的包 -package_name:指定不安装的包在安装过程中默认安装的软件包,安装软件时会⾃动分析依赖关系。

脚本段(可选) %pre:安装系统前执⾏的命令或脚本(由于只依赖于启动镜像,⽀持的命令很少) %post:安装系统后执⾏的命令或脚本(基本⽀持所有命令)# kickstart选项指令段的说明:【必须的选项】:1.auth或者authconfig :验证选项--useshadow或者--enableshadow启⽤shadow⽂件来验证--passalgo=sha512使⽤sha512算法2.bootloader: 指定如何安装引导程序,要求必须已选择分区、已选择引导程序、已选择软件包,如果没选择将会停⽌⽽不会询问--location=mbr 指定引导程序的位置,默认为mbr,还可以指定none或者包含bootloader的引导块所在分区--driveorder=sda 指定grub安装在哪个分区以及指定寻找顺序,--driverorder=sda sdc sdb--append="crashkernel=auto rhgb quiet"指定内核参数3.keyboard:指定键盘类型,⼀般使⽤美式键盘"keyboard us",新版的kickstart的格式有所变化,但也⽀持"keyboard us"这样的⽼格式ng:指定语⾔,如"lang en_US.UTF-8"5.rootpw:设置root⽤户的密码--iscrypted:使⽤加密密码,可以使⽤MD5,SHA-256,sha-512等。

Kickstart无人值守安装CentOS5

Kickstart无人值守安装CentOS5

Kickstart无人值守安装CrntOS5原理和概念:什么是PXE预启动执行环境(Preboot eXecution Environment,PXE,也被称为预执行环境)是让计算机通过网卡独立地使用数据设备(如硬盘)或者安装操作系统。

什么是KickStartKickstart是红帽创建的一种安装方法,使用kickstart,系统管理员可以创建一个文件,这个文件包含了在典型的安装过程中所遇到的问题的答案。

实现网络安装的过程是这样的:客户机PXE网络启动------>通过网际协议(IP)、用户数据报协议(UDP)、动态主机设定协定(DHCP)------->客户机获得IP------>通过小型文件传输协议(TFTP) 从TFTP Server上下载PEX引导文件------>启动引导程序进入安装界面------>根据default文件,通过超文本传送协议(HTTP)去HTTP Server下载ks.cfg文件----->根据ks.cf文件去HTTP Server下载RPM包并自动安装系统------>完成安装。

本次实验环境介绍:虚拟机:VMware Workstation 9.02 for windows服务端centOS5.8 ,IP 192.168.1.200,虚拟机网卡设置为桥接模式。

执行 PXE + KickStart安装要求:• DHCP 服务用来给客户机分配IP;• TFTP 服务用来存放PXE的相关文件,比如:系统引导文件;• HTTP 服务用来存放系统安装文件;• KickStart用来生成ks.cfg配置文件;• 带有一个 PXE 支持网卡的将安装的主机;安装步骤1.构建本地yum源[可选==如果VM不能连接到internet][root@localhost ~]# mount /dev/cdrom /media[root@localhost ~]# mv /etc/yum.repos.d/ ~[root@localhost ~]# vim /etc/yum.repos.d/local-source.repo[rhel-source]name=RHEL 6.2 Local Sourcebaseurl=file:///mediaenabled=1gpgcheck=02.安装相关软件包[root@localhost ~]# yum -y install dhcp httpd tftp-server system-config-kickstart3.创建安装源目录[root@localhost ~]# mkdir /var/www/html/centos54.挂载安装ISO安装源[root@localhost ~]# echo "/dev/cdrom /var/www/html/centos5 iso9660 \ defaults 0 0" >> /etc/fstab[root@localhost ~]# mount -a5.创建pxelinux.cfg目录[root@localhost ~]# mkdir /tftpboot/pxelinux.cfg6.拷贝PXE启动相关文件[root@localhost ~]# cp /usr/lib/syslinux/pxelinux.0 /tftpboot/[root@localhost ~]# cp /var/www/html/centos5/isolinux/isolinux.cfg \/tftpboot/pxelinux.cfg/default[root@localhost ~]# cp /var/www/html/centos5/isolinux/* /tftpboot/7.生成KS文件(图形界面下)[root@localhost ~]# system-config-kickstart[root@localhost ~]# cp ks.cfg /var/www/html/7.1.一个KS示例文件-CentOS5.8[root@localhost ~]# cat /var/www/html/ks.cfg#platform=x86, AMD64, Intel EM64T# System authorization informationauth --useshadow --enablemd5# System bootloader configuration#key --skip #如果是RHEL需要添加这行bootloader --location=mbr# Clear the Master Boot Recordzerombr# Partition clearing informationclearpart --all --initlabel# Use text mode installtext# Firewall configurationfirewall --enabled --ssh --trust=eth0,eth1# Run the Setup Agent on first bootfirstboot --disable# System keyboardkeyboard us# System languagelang en_US# Installation logging levellogging --level=info# Use network installationurl --url=http://192.168.1.200/centos5# Network informationnetwork --bootproto=dhcp --device=eth0 --onboot=onnetwork --bootproto=dhcp --device=eth1 --onboot=on#Root passwordrootpw --iscrypted $1$TrBGQ8pS$H3SgzJS1uofc0UXlq0h.4.# SELinux configurationselinux --permissive# System timezonetimezone --isUtc America/New_York# Install OS instead of upgradeinstall# X Window System configuration informationxconfig --defaultdesktop=GNOME --depth=24 --resolution=1280x800 # Disk partitioning informationpart /boot --bytes-per-inode=4096 --fstype="ext3" --size=500 part swap --bytes-per-inode=4096 --fstype="swap" --size=16000 part / --bytes-per-inode=4096 --fstype="ext3" --grow --size=1%packages@admin-tools@base#root默认密码:1234%^&*8.指定KS文件,编辑/tftpboot/pxelinux.cfg/default 添加:append initrd=initrd.img ks=http://192.168.1.200/ks.cfg修改完成后需要:wq!强制保持退出8.1.一个default示例文件:[root@localhost ~]# cat /tftpboot/pxelinux.cfg/defaultdefault linuxprompt 1timeout 60display boot.msgF1 boot.msgF2 options.msgF3 general.msgF4 param.msgF5 rescue.msglabel linuxkernel vmlinuzappend initrd=initrd.img ks=http://192.168.1.200/ks.cfglabel textkernel vmlinuzappend initrd=initrd.img textlabel kskernel vmlinuzappend ks initrd=initrd.imglabel locallocalboot 1label memtest86kernel memtestappend -9.创建并修改DHCP配置文件[root@localhost ~]# \cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample \ /etc/dhcpd.conf9.1.一个DHCP示例文件[root@localhost ~]# cat /etc/dhcpd.confddns-update-style interim;ignore client-updates;#添加下面两行next-server 192.168.1.200; #此处为PXE服务IPfilename "pxelinux.0";subnet 192.168.1.0 netmask 255.255.255.0 {# --- default gatewayoption routers 192.168.1.1;option subnet-mask 255.255.255.0;option nis-domain "";option domain-name "";option domain-name-servers 8.8.8.8;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).

RHEL6 PXE DHCP FTP Kickstart无人值守安装RHCE实验室环境

RHEL6 PXE DHCP FTP Kickstart无人值守安装RHCE实验室环境

RHEL6+PXE+DHCP+FTP+Kickstart无人值守安装RHCE实验室环境原理和概念:1.1 什么是PXE严格来说,PXE 并不是一种安装方式,而是一种引导的方式。

进行PXE 安装的必要条件是要安装的计算机中包含一个PXE 支持的网卡(NIC),即网卡中必须要有PXE Client。

PXE (Pre-boot Execution Environment)协议使计算机可以通过网络启动。

协议分为client 和server 端,PXE client 在网卡的ROM 中,当计算机引导时,BIOS 把PXE client 调入内存执行,由PXE client 将放置在远端的文件通过网络下载到本地运行。

运行PXE 协议需要设置DHCP 服务器和TFTP 服务器。

DHCP 服务器用来给PXE client(将要安装系统的主机)分配一个IP 地址,由于是给PXE client 分配IP 地址,所以在配置DHCP 服务器时需要增加相应的PXE 设置。

此外,在PXE client 的ROM 中,已经存在了TFTP Client。

PXE Client 通过TFTP 协议到TFTP Server 上下载所需的文件。

1.2 什么是KickStartKickStart是一种无人职守安装方式。

KickStart的工作原理是通过记录典型的安装过程中所需人工干预填写的各种参数,并生成一个名为ks.cfg的文件;在其后的安装过程中(不只局限于生成KickStart安装文件的机器)当出现要求填写参数的情况时,安装程序会首先去查找KickStart生成的文件,当找到合适的参数时,就采用找到的参数,当没有找到合适的参数时,才需要安装者手工干预。

这样,如果KickStart文件涵盖了安装过程中出现的所有需要填写的参数时,安装者完全可以只告诉安装程序从何处取ks.cfg文件,然后去忙自己的事情。

等安装完毕,安装程序会根据ks.cfg中设置的重启选项来重启系统,并结束安装。

kickstart与preseed简介
在我们手动安装操作系统时,需要回答各种提示问题,而针对某种特定应用时,这种回答完全有章可循,如果我们能在安装操作系统时将其中出现的各种问题的应答内容提前写好,那么整个操作系统的安装就可以自动完成。

kickstart是Red Hat公司针对自动安装Red Hat、Fedora与CentOS这3种同一体系
的操作系统而制定的问答规范。

它一般会以.cfg作为文件后缀名,不仅可以自动应答一些
简单问题,还可以指定操作系统需要安装的各种软件包,更可以在操作系统完装完成后自动执行一些脚本,这些脚本可以让我们直接配置系统。

通常,kickstart配置文件通过命令行工具system-config-kickstart生成。

当然,我们更喜欢在CentOS图形界面环境下生成用于定制操作系统安装的配置文件。

preseed则是Debian/Ubuntu操作系统自动安装的问答规范,同样可以预定义Ubuntu
如何安装,其配置更多通过手动处理。
