1、配置yum源 安装操作系统时我们选择的包不一定会含DHCP、TFTP、NFS服务，所以我们需要搭建yum源安装这些软件

====================

挂载光驱

====================

[root@localhost ~]# mount /dev/sr0 /mnt/

mount: /dev/sr0 is write-protected, mounting read-only

[root@localhost ~]# cd /etc/yum.repos.d/

[root@localhost yum.repos.d]# mkdir bak

[root@localhost yum.repos.d]# mv *.repo ./bak/

[root@localhost yum.repos.d]# vim base.repo

=========================

编辑base.repo文件，如下：

=========================

[base]

name=base

baseurl=file:///mnt/ #iso文件挂载在那个目录下这里写哪个目录，如挂载在/mnt/目录下，这里就是baseurl=file:///mnt/

enabled=1

gpgcheck=0

[root@localhost yum.repos.d]# yum makecache

Loaded plugins: fastestmirror, langpacks

Loading mirror speeds from cached hostfile

...

Metadata Cache Created

2、安装软件 [root@localhost yum.repos.d]# yum install dhcp tftp xinetd tftp-server nfs-utils rpcbind -y

3、创建相关文件夹并copy相应的文件 [root@localhost dhcp]# mkdir -p /centos/centos76 [root@localhost dhcp]# cp /mnt/* /centos/centos76/ [root@localhost ~]# mkdir /var/lib/tftpboot/uefi ============= 提取shim.ufi ============= [root@localhost ~]# cp /centos/centos76/Packages/shim-aa64-12-1.el7.aarch64.rpm /tm [root@localhost ~]# cd /tmp [root@localhost ~]# rpm2cpio shim-aa64-12-1.el7.aarch64.rpm |cpio -idmv [root@localhost ~]# cp /tmp/boot/efi/EFI/redhat/shim.efi /var/lib/tftpboot/uefi/ [root@localhost ~]# cp /centos/centos76/EFI/BOOT/grubaa64.efi /var/lib/tftpboot/uefi/ [root@localhost ~]# cp /centos/centos76/images/pxeboot/vmlinuz /var/lib/tftpboot/uefi/ [root@localhost ~]# cp /centos/centos76/images/pxeboot/initrd.img /var/lib/tftpboot/uefi/ [root@localhost ~]# vim /var/lib/tftpboot/uefi/grub.cfg set timeout=60 menuentry 'CentOS 7' { linux uefi/vmlinuz ip=dhcp inst.repo=nfs:9.43.3.1:/centos/centos76 inst.resolution=1024x768 initrd uefi/initrd.img } #inst.repo 为安装源路径，inst.resolution设置分辨率，ip=dhcp设置dhcp动态IP ======================================= 检查/var/lib/tftpboot/uefi/下的文件 ======================================= [root@localhost ~]# ls /var/lib/tftpboot/uefi/ grub.cfg grubaa64.efi initrd.img shim.efi vmlinuz [root@localhost ~]# chmod 777 *

创建ks.cfg文件，将ks.cfg文件cp到/centos目录下并修改权限为777

4、配置文件 ================== 配置DHCPD服务文件 ================== [root@localhost yum.repos.d]# vim /etc/dhcp/dhcpd.conf ddns-update-style none; ignore client-updates; default-lease-time 359200; max-lease-time 800000; next-server 9.43.3.1; #pxe源服务器的IP地址 subnet 9.43.0.0 netmask 255.255.0.0 { #subnet pxe dhcp分配的地址段 netmaskpxe dhcp分配的地址段掩码 range dynamic-bootp 9.43.3.100 9.43.200.250; #pxe dhcp可分配的地址 filename "uefi/shim.efi"; } [root@localhost ~]# systenctl restart dhcpd [root@localhost ~]# systenctl enable dhcpd

=============

配置tftp服务

=============

[root@localhost ~]# vim /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/ -u nobody

disable = no #将yes改为no

per_source =11

cps =100 2

flags = IPv4

}

[root@localhost ~]# systenctl restart tftp

[root@localhost ~]# systenctl enable tftp

===========

配置NFS服务

===========

[root@localhost ~]# vim /etc/exports

/centos/ *(root_squash,crossmnt)

[root@localhost ~]# systenctl restart nfs

[root@localhost ~]# systenctl enable nfs

[root@localhost ~]# showmount -e localhost #验证nfs配置

Export list for localhost:

/centos *

5、关闭防火墙和SELINUX [root@localhost ~]# systenctl stop firewalld [root@localhost ~]# systenctl disable firewalld [root@localhost ~]# vim /etc/sysconfig/selinux SELINUX=disabled #将enforcing修改成disabled
