PXE推送，NFS切換本地源

yum -y install tftp-server

修改TFTP配置文件

vi /etc/xinetd.d/tftp 

service tftp

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

}

yum -y install dhcp  

安裝DHCP 修改配置文件

cat > /etc/dhcp/dhcpd.conf << EOF

allow booting;

allow bootp;

ddns-update-style interim;

ignore client-updates;

subnet 192.168.10.0 netmask 255.255.255.0 {

建立NFS目錄 

mkdir /nfs     ######存放安裝鏡像 

mkdir /config  #####存放KS文件

修改NFS配置

vi /etc/exports

/nfs  *(ro)

/config  *(ro)

yum -y install syslinux

cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot

mkdir -p /var/lib/tftpboot/pxelinux.cfg

mount /dev/sr0 /nfs  掛載安裝源

cp /nfs/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

vim default

default文件配置

-----------------------

default linux

timeout 60

display boot.msg

label linux

  kernel vmlinuz

  append initrd=initrd.img inst.stage2=nfs:192.168.10.1:/nfs ks=nfs:192.168.10.1:/config/ks.cfg quiet

menu end

ks文件能夠用system-config-kickstart生成

出現不能選擇安裝包的問題 增長YUM源

vi /etc/yum.repos.d/development.repo 

[development]

name=base

baseurl=file:///nfs

enabled=1

gpgcheck=0

掛載ISO文件 切換安裝鏡像 每次攜帶虛擬機更換鏡像

#!/bin/bash

mount /dev/sr0 /nfs 

/bin/cp -f /nfs/images/pxeboot/initrd.img /var/lib/tftpboot/

/bin/cp -f /nfs/images/pxeboot/vmlinuz /var/lib/tftpboot/

/bin/cp -f /nfs/isolinux/vesamenu.c32 /var/lib/tftpboot/

/bin/cp -f /nfs/isolinux/boot.msg /var/lib/tftpboot/

systemctl stop firewalld.service
