本实验实现在centos8系统上利用PXE自动化安装Centos6,7,8三个系统
(1) 安装前准备
关闭防火墙和SELINUX,DHCP服务器静态IP
网络要求:关闭Vmware软件中的DHCP服务,基于NAT模式
(2) 安装相关软件包并启动
[root@centos8 ~]#dnf -y install dhcp-server tftp-server httpd syslinux-nonlinux
[root@centos8 ~]#systemctl enable --now httpd tftp dhcpd
(3)配置DHCP服务
[root@centos8 ~]#cp /usr/share/doc/dhcp-server/dhcpd.conf.example /etc/dhcp/dhcpd.conf
[root@centos8 ~]#vim /etc/dhcp/dhcpd.conf
1 option domain-name "example.com";
2 option domain-name-servers 180.76.76.76,223.6.6.6;
3 default-lease-time 600;
4 max-lease-time 7200;
5 log-facility local7;
6 subnet 10.0.0.0 netmask 255.255.255.0 {
#分配的IP范围
7 range 10.0.0.100 10.0.0.200;
#路由网关
8 option routers 10.0.0.2;
#本机IP
9 next-server 10.0.0.8;
10 filename "pxelinux.0";
11 }
[root@centos8 ~]#systemctl start dhcpd
(4)准备yum 源和相关目录(将centos8系统上安装三个光盘,分别对应相应的iOS文件)
[root@centos8 ~]#mkdir -pv /var/www/html/centos/{6,7,8}/os/x86_64/
#centos6的为sr0,centos7的为sr2,centos8的为sr1
[root@centos8 ~]#lsblk

(6) 准备PXE启动相关文件
[root@centos8 ~]#mkdir /var/lib/tftpboot/centos{6,7,8}
#准备CentOS6,7,8各自的内核相关文件
[root@centos8 ~]#cp /var/www/html/centos/6/os/x86_64/isolinux/{vmlinuz,initrd.img} /var/lib/tftpboot/centos6
[root@centos8 ~]#cp /var/www/html/centos/7/os/x86_64/isolinux/{vmlinuz,initrd.img} /var/lib/tftpboot/centos7
[root@centos8 ~]#cp /var/www/html/centos/8/os/x86_64/isolinux/{vmlinuz,initrd.img} /var/lib/tftpboot/centos8
[root@centos8 ~]#cp /usr/share/syslinux/{pxelinux.0,menu.c32} /var/lib/tftpboot/
#以下三个文件是CentOS8安装所必须文件,CentOS6,7则不需要
[root@centos8 ~]#cp /var/www/html/centos/8/os/x86_64/isolinux/{ldlinux.c32,libcom32.c32,libutil.c32} /var/lib/tftpboot/
#生成安装菜单文件
[root@centos8 ~]#mkdir /var/lib/tftpboot/pxelinux.cfg/
[root@centos8 ~]#cp /var/www/html/centos/8/os/x86_64/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
#最终目录结构如下
[root@centos8 ~]#tree /var/lib/tftpboot
.
├── centos6

│ └── vmlinuz

4 directories, 12 files
(7) 准备启动菜单文件
[root@centos8 ~]#vim /var/lib/tftpboot/pxelinux.cfg/default
default menu.c32
timeout 600
menu title Install CentOS Linux
label linux8
menu label Auto Install CentOS Linux ^8
kernel centos8/vmlinuz
append initrd=centos8/initrd.img ks=http://10.0.0.8/ks/centos8.cfg
label linux7
menu label Auto Install CentOS Linux ^7
kernel centos7/vmlinuz
append initrd=centos7/initrd.img ks=http://10.0.0.8/ks/centos7.cfg
label linux6
menu label Auto Install CentOS Linux ^6
kernel centos6/vmlinuz
append initrd=centos6/initrd.img ks=http://10.0.0.8/ks/centos6.cfg
label manual
menu label ^Manual Install CentOS Linux 8.0
kernel centos8/vmlinuz
append initrd=centos8/initrd.img
inst.repo=http://10.0.0.8/centos/8/os/x86_64/
label rescue
menu label ^Rescue a CentOS Linux system 8
kernel centos8/vmlinuz
append initrd=centos8/initrd.img
inst.repo=http://10.0.0.8/centos/8/os/x86_64/ rescue
label local
menu default
menu label Boot from ^local drive
localboot 0xffff
最后自己试一下是否能够安装就好啦
