[root@pxe~]# yum -y install dhcp tftp-server.x86_64 httpd syslinux
[root@pxe~]# systemctl stop firewalld
[root@pxe~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@pxe~]# mkdir -p /media/cdrom
[root@pxe~]# mount /dev/sr0 /media/cdrom【2】配置dhcp服务
[root@pxe~]# cat /etc/dhcp/dhcpd.conf
subnet 10.0.0.0 netmask 255.255.255.0 {
range 10.0.0.70 10.0.0.80;
default-lease-time 3600;
filename "pxelinux.0";
next-server 10.0.0.10;
}
[root@pxe~]# systemctl enable --now dhcpd【3】配置tftp服务
[root@pxe ~]# vim /etc/xinetd.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = no
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
[root@pxe~]# systemctl enable --now tftp.socket【4】拷贝pxe服务器的相关文件到tftp的根目录
[root@pxe~]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
[root@pxe~]# cp /usr/share/syslinux/menu.c32 /var/lib/tftpboot/
[root@pxe~]# cp /media/cdrom/isolinux/vmlinuz /var/lib/tftpboot/
[root@pxe~]# cp /media/cdrom/isolinux/initrd.img /var/lib/tftpboot/【5】创建pxelinux.cfg文件
[root@pxe~]# cd /var/lib/tftpboot/
[root@pxe tftpboot]# mkdir pxelinux.cfg
[root@pxe tftpboot]# vim pxelinux.cfg/default
default menu.c32

append initrd=initrd.img method=http://10.0.0.10/centos7 ks=http://10.0.0.10/ks.cfg【6】配置httpd
[root@pxe tftpboot]# cd /var/www/html/
[root@pxe html]# systemctl start httpd.service
[root@pxe html]# mkdir centos7
[root@pxe html]# mount /dev/cdrom /var/www/html/centos7- 访问测试（10.0.0.10/centos7）
【7】Kickstart自动化文件
[root@ansible html]# cp /root/anaconda-ks.cfg /var/www/html/
[root@ansible html]# mv anaconda-ks.cfg ks.cfg
[root@ansible html]# chmod +r ks.cfg- 测试访问（10.0.0.10/ks.cfg）,确保能正常访问
- 修改配置ks.cfg
[root@pxe html]# vim ks.cfg

reboot【8】重启所有服务
[root@pxe ~]# systemctl restart httpd
[root@pxe ~]# systemctl restart tftp.socket
[root@pxe ~]# systemctl restart dhcpd【9】验证
- 准备一台新的虚拟机，网络模式必须跟服务端相同，客户机内存必要足够（至少2G），光盘设置自动检测
【10】启动
- 等待安装完成（几分钟）
【11】完成
