1、配置yum源
安裝作業系統時我們選擇的包不一定會含DHCP、TFTP、NFS服務,是以我們需要搭建yum源安裝這些軟體
====================
挂載光驅
====================
[[email protected] ~]# mount /dev/sr0 /mnt/
mount: /dev/sr0 is write-protected, mounting read-only
[[email protected] ~]# cd /etc/yum.repos.d/
[[email protected] yum.repos.d]# mkdir bak
[[email protected] yum.repos.d]# mv *.repo ./bak/
[[email protected] yum.repos.d]# vim base.repo
=========================
編輯base.repo檔案,如下:
=========================
[base]
name=base
baseurl=file:///mnt/ #iso檔案挂載在那個目錄下這裡寫哪個目錄,如挂載在/mnt/目錄下,這裡就是baseurl=file:///mnt/
enabled=1
gpgcheck=0
[[email protected] yum.repos.d]# yum makecache
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
...
Metadata Cache Created
2、安裝軟體
[[email protected] yum.repos.d]# yum install dhcp tftp xinetd tftp-server nfs-utils rpcbind -y
3、建立相關檔案夾并copy相應的檔案
[[email protected] dhcp]# mkdir -p /centos/centos76
[[email protected] dhcp]# cp /mnt/* /centos/centos76/
[[email protected] ~]# mkdir /var/lib/tftpboot/uefi
=============
提取shim.ufi
=============
[[email protected] ~]# cp /centos/centos76/Packages/shim-aa64-12-1.el7.aarch64.rpm /tm
[[email protected] ~]# cd /tmp
[[email protected] ~]# rpm2cpio shim-aa64-12-1.el7.aarch64.rpm |cpio -idmv
[[email protected] ~]# cp /tmp/boot/efi/EFI/redhat/shim.efi /var/lib/tftpboot/uefi/
[[email protected] ~]# cp /centos/centos76/EFI/BOOT/grubaa64.efi /var/lib/tftpboot/uefi/
[[email protected] ~]# cp /centos/centos76/images/pxeboot/vmlinuz /var/lib/tftpboot/uefi/
[[email protected] ~]# cp /centos/centos76/images/pxeboot/initrd.img /var/lib/tftpboot/uefi/
[[email protected] ~]# 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 為安裝源路徑,inst.resolution設定分辨率,ip=dhcp設定dhcp動态IP
=======================================
檢查/var/lib/tftpboot/uefi/下的檔案
=======================================
[[email protected] ~]# ls /var/lib/tftpboot/uefi/
grub.cfg grubaa64.efi initrd.img shim.efi vmlinuz
[[email protected] ~]# chmod 777 *
建立ks.cfg檔案,将ks.cfg檔案cp到/centos目錄下并修改權限為777
4、配置檔案
==================
配置DHCPD服務檔案
==================
[[email protected] 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源伺服器的IP位址
subnet 9.43.0.0 netmask 255.255.0.0 { #subnet pxe dhcp配置設定的位址段 netmaskpxe dhcp配置設定的位址段掩碼
range dynamic-bootp 9.43.3.100 9.43.200.250; #pxe dhcp可配置設定的位址
filename "uefi/shim.efi";
}
[[email protected] ~]# systenctl restart dhcpd
[[email protected] ~]# systenctl enable dhcpd
=============
配置tftp服務
=============
[[email protected] ~]# 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改為no
per_source =11
cps =100 2
flags = IPv4
}
[[email protected] ~]# systenctl restart tftp
[[email protected] ~]# systenctl enable tftp
===========
配置NFS服務
===========
[[email protected] ~]# vim /etc/exports
/centos/ *(root_squash,crossmnt)
[[email protected] ~]# systenctl restart nfs
[[email protected] ~]# systenctl enable nfs
[[email protected] ~]# showmount -e localhost #驗證nfs配置
Export list for localhost:
/centos *
5、關閉防火牆和SELINUX
[[email protected] ~]# systenctl stop firewalld
[[email protected] ~]# systenctl disable firewalld
[[email protected] ~]# vim /etc/sysconfig/selinux
SELINUX=disabled #将enforcing修改成disabled
