Linux centos PXE无人值守安装 DHCP+TFTP+FTP+Kickstart

网络模式:NAT模式(共享主机的IP地址)

DHCP / TFTP IP:192.168.220.137

HTTP / FTP / NFS IP:192.168.220.137

环境搭建:

yum install -y tftp-server dhcp system-config-kickstart vsftp xinetd syslinux

1.挂载ISO文件然后把光盘中的文件拷贝至/var/ftp/pub中

mount /dev/cdrom /media/CentOS/

cp -Rf /media/CentOS/* /var/ftp/pub/

2. a.initrd.img  pxelinux.0  vmlinuz 拷贝至 /tftpboot目录中mkdir /tftpboot

chmod 777 -Rf /tfrpboot/

cp /media/CentOS/isolinux/initrd.img /tftpboot

cp /media/CentOS/isolinux/vmlinuz /tftpboot

cp /usr/share/syslinux/pxelinux.0 /tftpboot  ##找到pxelinux.0 文件 (find / -name pxelinux.0

b.default文件放在/tftpboot/pxelinux.cfg/

mkdir /tftpboot/pxelinux.cfg/

cp /var/ftp/pub/isolinux/isolinux.cfg  /tftpboot/pxelinux.cfg/default


配置文件参数:

1.vi /etc/dhcp/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

subnet 192.168.220.0 netmask 255.255.255.0 {

        allow booting;

        allow bootp;

        allow unknown-clients;

        option routers                  192.168.222.137;

        option subnet-mask              255.255.255.0;

        option domain-name-servers      192.168.220.2;

        option time-offset              -18000; # Eastern Standard Time

# --- 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 192.168.220.140 192.168.220.150;

        default-lease-time 21600;

        max-lease-time 43200;

        next-server  192.168.220.137;

        filename "pxelinux.0";

}

2.vi /etc/xinetd.d/tftp

# 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

{

        socket_type             = dgram

        protocol                = udp

        wait                    = yes

        user                    = root

        server                  = /usr/sbin/in.tftpd

        server_args             = -s /tftpboot

        disable                 = no

        per_source              = 11

        cps                     = 100 2

        flags                   = IPv4

}

3.vi /etc/vsftp/vsftpd.conf

无需改动

4.vi /tftpboot/pxelinux.cfg/default 

default linux

prompt 1

timeout 30

label linux

kernel vmlinuz

append initrd=initrd.img ks=ftp://192.168.220.137/ks.cfg

5.在桌面环境下配置Kickstart

启动X Windows 环境

startx

配置Kickstart

vim /var/ftp/ks.cfg

#platform=x86, AMD64, 或 Intel EM64T

#version=DEVEL

# Firewall configuration

firewall --disabled

# Install OS instead of upgrade

install

# Use network installation

url --url="ftp://192.168.220.137/pub"

# Root password

rootpw --iscrypted $1$CpoBgXT7$AzEBGDew56m/vIUoIH7SU.

# System authorization information

auth  --useshadow  --passalgo=sha512

# Use graphical install

graphical

firstboot --disable

# System keyboard

keyboard us

# System language

lang en_US

# SELinux configuration

selinux --disabled

# Installation logging level

logging --level=info

# Reboot after installation

reboot

# System timezone

timezone  Asia/Chongqing

# Network information

network  --bootproto=dhcp --device=eth0 --onboot=on

# System bootloader configuration

bootloader --location=mbr

# Clear the Master Boot Record

zerombr

# Partition clearing information

clearpart --all --initlabel

# Disk partitioning information

part /boot --fstype="ext4" --size=100

part swap --fstype="swap" --size=512

part / --fstype="ext4" --grow --size=1

%packages

@debugging

@legacy-unix

@network-file-system-client

@web-server


%end

测试:

servcei iptables stop

setenforce 0

service dhcpd start

service xinetd start

service vsftpd start

以上可完成PXE无人值守安装操作系统

错误:如果出现error downloading Kickstart file 

解决:/var/ftp/ks.cfg 权限问题 或者 路径问题
