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

34222

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 httpd xinetd syslinux
1.挂载ISO文件,复制光盘全部内容至http 的根目录/var/www/html/ 下
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
cp -r /mnt/cdrom/ /var/www/html/
2.配置TFTP
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
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4 }
3.配置支持PXE的启动程序
cp /var/www/html/cdrom/images/pxeboot/{initrd.img,vmlinuz} /var/lib/tftpboot/
cp /var/www/html/cdrom/isolinux/*.msg /var/lib/tftpboot/
chmod 777 -Rf /var/lib/tftpboot/
mkdir /var/lib/tftpboot/pxelinux.cfg
cp /var/www/html/cdrom/isolinux/isolinux.cfg  /var/lib/tftpboot/pxelinux.cfg/default
vi /var/lib/tftpboot/pxelinux.cfg/default

default ks
prompt 1
timeout 6
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=http://192.168.220.137/ks.cfg initrd=initrd.img
label local
localboot 1
label memtest86
kernel memtest
append -
4.配置DHCP

vim /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";
}
5.生成ks.cfg 文件

在桌面环境下配置Kickstart
vim /var/www/html/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="http://192.168.220.137/cdrom"
# Root password
rootpw --iscrypted $1$cWoyK/RZ$4mca7VVTDACquj0bE6aSR1
# 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
