CentOS 6.5 PXE自动化部署系统
拓扑图如下：
步骤：
1、 安装http服务，上传ISO文件
[root@UCS-1 ~]# yum install httpd –y
[root@UCS-1 ~]# chkconfig --add httpd
[root@UCS-1 ~]# chkconfig --level 35 httpd on
[root@UCS-1 ~]# /etc/init.d/httpd start
[root@UCS-1 ~]# mkdir -p /var/www/html/os/6
[root@UCS-1 ~]# mount /dev/cdrom /mnt
[root@UCS-1 ~]# cd /mnt
[root@UCS-1 mnt]# cp -r * /var/www/html/os/6
[root@UCS-1 ~]# yum install tftp-server –y
[root@UCS-1 mnt]# cp /var/www/html/os/6/isolinux/boot.msg /var/lib/tftpboot/
[root@UCS-1 mnt]# cp /var/www/html/os/6/images/pxeboot/initrd.img /var/lib/tftpboot/
[root@UCS-1 mnt]# cp /var/www/html/os/6/images/pxeboot/vmlinuz /var/lib/tftpboot/
[root@UCS-1 html]# cp /var/www/html/os/6/isolinux/splash.jpg /var/lib/tftpboot/
[root@UCS-1 html]# cp /var/www/html/os/6/isolinux/vesamenu.c32 /var/lib/tftpboot/
[root@UCS-1 mnt]# yum -y install syslinux
[root@UCS-1 mnt]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
[root@UCS-1 mnt]# mkdir /var/lib/tftpboot/pxelinux.cfg
[root@UCS-1mnt]#cp /var/www/html/os/6/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
2、 修改tftp配置文件
[root@UCS-1 mnt]# vi /etc/xinetd.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no（原来yes修改成为no）
per_source = 11
cps = 100 2
flags = IPv4
}
[root@UCS-1 mnt]# chkconfig xinetd on
[root@UCS-1 mnt]# chkconfig --level 35 xinetd on
[root@UCS-1 mnt]# yum -y install dhcp
[root@UCS-1 mnt]# vi /etc/dhcp/dhcpd.conf
3、 安装dhcp服务
[root@UCS-1 mnt]# vi /etc/dhcp/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
allow booting;
allow bootp;
subnet 192.168.8.0 netmask 255.255.255.0{
range 192.168.8.110 192.168.8.120;
option routers 192.168.8.254;
option broadcast-address 192.168.8.255;
default-lease-time 600;
max-lease-time 7200;
next-server 192.168.8.254;
filename "pxelinux.0";
} [root@UCS-1 mnt]# /etc/init.d/dhcpd start
4、 安装system-config-kickstart.noarch
[root@UCS-1 mnt]# yum install system-config-kickstart.noarch -y
5、 进入图形界面执行[root@UCS-1 mnt]# /etc/init.d/dhcpd start
6、 生成ks.cfg文件
#platform=x87, AMD64, 或 Intel EM64T
#version=DEVEL
# Firewall configuration
firewall --disabled
# Install OS instead of upgrade
install
# Use network installation
url --url="http://192.168.8.254/os/6"
#repo --name="CentOS" --baseurl=cdrom:sr0 --cost=100（注释掉，否则启动从光盘安装）
# Root password
rootpw --iscrypted $1$EuW9dIZG$Vclkz/TcHRuoiBqYdPvTD0
# System authorization information
auth --useshadow --passalgo=sha512
# Use text mode install
text
# System keyboard
keyboard us
# System language
lang zh_CN
# SELinux configuration
selinux --disabled
# Do not configure the X Window System
skipx
# Installation logging level
logging --level=info
# Reboot after installation
reboot
# System timezone
timezone Asia/Shanghai
# Network information
network --bootproto=dhcp --device=eth0 --onboot=on
network --bootproto=dhcp --device=eth1 --onboot=on
# System bootloader configuration
bootloader --append="crashkernel=auto rhgb quiet" --location=mbr --driveorder="sda"
# Clear the Master Boot Record
zerombr
# Partition clearing information
clearpart --all
# Disk partitioning information
part / --fstype="ext4" --grow --size=1

7、 修改PXE引导文件的ks.cfg，修改如下部分
[root@UCS-1 html]# vi /var/lib/tftpboot/pxelinux.cfg/default
timeout 60 # 修改等待时间为6秒
display boot.msg
menu background splash.jpg
menu title Welcome to CentOS 6.5!
menu color border 0 #ffffffff #00000000
menu color sel 7 #ffffffff #ff000000
menu color title 0 #ffffffff #00000000
menu color tabmsg 0 #ffffffff #00000000
menu color unsel 0 #ffffffff #00000000
menu color hotsel 0 #ff000000 #ffffffff
menu color hotkey 7 #ffffffff #ff000000
menu color scrollbar 0 #ffffffff #00000000
label linux
menu label ^Install or upgrade an existing system
menu default
kernel vmlinuz
append initrd=initrd.img ks=http://192.168.8.254/ks.cfg 指定ks.cfg文件目录
label vesa
menu label Install system with ^basic video driver
kernel vmlinuz
append initrd=initrd.img xdriver=vesa nomodeset
label rescue
menu label ^Rescue installed system
注意部分：如果是多个网卡的话，还要打开路由功能
