◆案例◆ PXE+Kickstart-实现无人值守
**************************************************************************************************
****************************************************************************
◆安装PXE装机所需的软件◆
****************************************************************************
yum install -y vsftpd tftp tftp-server dhcp syslinux xinetd
a).拷贝镜像文件到FTP服务器目录
mkdir /var/ftp/pub/dvd #创建用于存放镜像的目录
chown ftp:ftp /var/ftp/pub/dvd #赋予ftp属组让其有权限
mount -t iso9660 /dev/sr0 /mnt #挂载安装光盘,后期拷贝文件用
cp -a /mnt/* /var/ftp/pub/dvd #拷贝光盘内容到dvd目录下
b).配置DHCP服务 <作用是分配IP，并指明TFTP地址>
在相应的区域中覆盖写入标★语句
--------------------------------------------------------------------------------------------------------------
vim /etc/dhcp/dhcpd.conf
1 #
2 # DHCP Server Configuration file.
3 # see /usr/share/doc/dhcp*/dhcpd.conf.example
4 # see dhcpd.conf(5) man page
5
★ subnet 192.168.1.0 netmask 255.255.255.0 { #指明分配网段/MAC
★ range 192.168.1.100 192.168.1.200; #分配的网段(100-200)
★ next-server 192.168.1.12; #指定TFTP服务器的地址
★ filename "pxelinux.0"; #指定PXE引导程序的文件名
★ }
--------------------------------------------------------------------------------------------------------------
c).修改TFTP配置文件,开启TFTP服务
在相应的区域中修改以下标★语句
--------------------------------------------------------------------------------------------------------------
vim /etc/xinetd.d/tftp
1 # default: off
2 # description: The tftp server serves files using the trivial file transfer \
3 # protocol. The tftp protocol is often used to boot diskless \
4 # workstations, download configuration files to network-aware printers, \
5 # and to start the installation process for some operating systems.
6 service tftp
7 {
8 socket_type = dgram
9 protocol = udp
10 wait = yes
11 user = root
12 server = /usr/sbin/in.tftpd
★ server_args = -s /tftpboot #设置默认工作目录
★ disable = no #设置开机自启动
15 per_source = 11
16 cps = 100 2
17 flags = IPv4
18 }
--------------------------------------------------------------------------------------------------------------
d).创建相关目录并拷贝所需文件
mkdir -p /tftpboot/pxelinux.cfg
cp -a /var/ftp/pub/dvd/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default
cp -a /usr/share/syslinux/pxelinux.0 /tftpboot/
chmod 644 /tftpboot/pxelinux.cfg/default
cp -a /var/ftp/pub/dvd/isolinux/* /tftpboot/
e).开启相关服务
systemctl restart dhcpd
systemctl restart tftp
systemctl restart vsftpd
systemctl restart xinetd
****************************************************************************
◆配置kisckstart无人值守安装脚本◆
****************************************************************************
a).安装主程序
yum install -y system-config-kickstart
b).配置安装脚本
system-config-kickstart #启动装机脚本生成工具(图形界面)
#此处应配置生成装机文件 本步骤跳过(以下是测试脚本)
--------------------------------------------------------------------------------------------------------------
vim 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://192.168.1.1/pub/dvd" #此处修改为本机IP
# Root password
rootpw --iscrypted $1$K4WAmqxk$ccusVq9PIk6f1uMqJ48fI1
# System authorization information
auth --useshadow --passalgo=sha512
# Use graphical install
graphical
# System keyboard
keyboard us
# System language
lang en_US
# SELinux configuration
selinux --disabled
# Do not configure the X Window System
skipx
# Installation logging level
logging --level=info
# System timezone
timezone Asia/Shanghai
# System bootloader configuration
bootloader --location=mbr
# Clear the Master Boot Record

# Partition clearing information
clearpart --all
# Disk partitioning information
part /boot --asprimary --fstype="ext4" --size=500
part swap --fstype="swap" --size=2000
part / --fstype="ext4" --grow --size=1
%packages
@base
%end
--------------------------------------------------------------------------------------------------------------
cp -a ks.cfg /var/ftp/pub/ #拷贝生成的脚本到指定目录下
c).打开引导文件,在相应的区域中修改以下标★语句
--------------------------------------------------------------------------------------------------------------
vim /tftpboot/pxelinux.cfg/default
61 label linux
62 menu label ^Install CentOS 7
63 menu default #添加
64 kernel vmlinuz
65 append initrd=initrd.img ks=ftp://192.168.20.10/pub/ks.cfg #指定主服务器IP地址
66
67 label check
68 menu label Test this ^media & install CentOS 7
69 # menu default #注释掉
70 kernel vmlinuz
71 append initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 rd.live.check quiet
--------------------------------------------------------------------------------------------------------------
d).另开虚拟机测试即可
