环境：虚拟机VM，Centos5.0
说明：我的ip地址为192.168.141.3，为客户机分配的ip地址范围为
192.168.141.180-192.168.141.182
一：安装DHCP服务器，配置后并设置开机启动（用来分配IP地址）
A；安装dhcp
B；修改配置文件
修改/etc/dhcpd.conf如下：
ddns-update-style interim; ignore client-updates; allow booting; #定义可以PXE方式启动allow bootp; #定义支持boottpclass "pxeclients" { match if substring(option vendor-class-identifier,0,9) = "PXEClient"; filename "/pxelinux.0"; #pxelinux.0启动引导文件存放路径next-server 192.168.141.3; #TFTP服务器ip地址，所以dhcpd与TFTP服务器不一定在一个机器 上 } subnet 192.168.141.0 netmask 255.255.255.0 { #DHCP服务器自身网段及子网掩码 # --- default gateway option routers 192.168.141.2;
option subnet-mask 255.255.255.0; option nis-domain "domain.org"; option domain-name "domain.org"; option domain-name-servers 192.168.141.2; #域名服务器ip，可以不使，但最好 设置一个免得安装中提示 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 192.168.141.180 192.168.141.182; #DHCP地址池 default-lease-time 21600; max-lease-time 43200; # we want the nameserver to appear at a fixed address # host ns {
#这个字段可以为指定MAC地址的机器指定固定的ip,也可不 使 # next-server marvin.redhat.com; # hardware ethernet 12:34:56:78:AB:CD; # fixed-address 207.175.42.254; # } }
C；设置开机启动
D；重启服务 /etc/init.d/dhcpd restart
二：安装FTP服务器，并设置开机启动（用来放置光盘的内容和ks问件）
A;安装vsftpd
B; 重启服务 /etc/init.d/vsftpd restart
三：安装TFTP服务器，一个是服务器端，一个是客户端，客户端主要用来做本机测试的（用来放置PXE启动时所需的文件）
A;安装tftp
B;修改/etc/xinetd.d/tftp如下：
# default: off # description: The tftp server serves files using the trivial file transfer \ # protocol. The tftp protocol is often used to boot diskless \ # workstations, download configuration files to network-aware printers, \ # and to start the installation process for some operating systems. service tftp { disable = no socket_type = dgram protocol = udp wait = yes user = root server = /usr/sbin/in.tftpd server_args = -s /tftpboot per_source = 11 cps = 100 2 flags = IPv4 }
C;重启服务 /etc/init.d/xinetd restart
四：挂载光盘到/var/ftp/pub
五：配置支持PXE的启动程序
A；拷贝启动引导文件：
B;拷贝内核文件，菜单选项文件，以及菜单配置文件：
C;我的/tftpboot目录结构：
D；拷贝/root/anaconda-ks.cfg 到/var/pub,并修改其权限
E；修改/tftpboot/pxelinux.cfg/default如下：
default ks prompt 1 timeout 60 display boot.msg F1 boot.msg F2 options.msg F3 general.msg F4 param.msg F5 rescue.msg label linux kernel vmlinuz append initrd=initrd.img label text kernel vmlinuz append initrd=initrd.img text label ks kernel vmlinuz append ks=ftp://192.168.141.3/anaconda-ks.cfg initrd=initrd.imglabel local localboot 1 label memtest86 kernel memtest append -
F；修改/var/ftp/anaconda-ks.cfg如下:
# Kickstart file automatically generated by anaconda. install url --url=ftp://192.168.141.3/publang en_US.UTF-8 keyboard us network --device eth0 --bootproto dhcp rootpw --iscrypted $1$oK96NKbn$9vjtYYXYpWTjuicKjciMH0 firewall --enabled --port=22:tcp authconfig --enableshadow --enablemd5 selinux --enforcing timezone --utc Asia/Shanghai bootloader --location=mbr --driveorder=sda --append="rhgb quiet" # The following is the partition information you requested # Note that any partitions you deleted are not expressed # here so unless you clear all partitions first, this is # not guaranteed to work clearpart --all --initlablepart /boot --fstype ext3 --size=100 --asprimary part swap --size=256 part / --fstype ext3 --size=1 --grow --asprimary %packages @admin-tools @base @base-x @core @development-libs @development-tools @dialup @editors @games @gnome-desktop @graphical-internet @graphics @network-server @office @printing @sound-and-video @system-tools @text-internet kernel-devel
六：测试，成功了：
总结：
另外几种路径的写法为：
HTTP:
default 文件 append ks=http://192.168.141.3/pub/ks.cfg initrd=initrd.img
anaconda-ks文件 url --url
NIS:
default文件 append ks=nfs:192.168.141.3:/pub/ks.cfg initrd=initrd.img
anaconda-ks nfs --server=192.168.141.3 --dir=/var/ftp/pub
另外：
clearpart --all --initlabel
--all 擦除系统上原有所有分区；
--initlabel 初始化磁盘卷标为系统架构的默认卷标
加了--initlabel可防止如下情况的出现：
