1.实验环境配置

        1.1红帽7主机

        1.2.开启图形 init 5

        1.3.配置网络为手动，配置网络可用

        1.4.关闭Vmvare DHCP功能

2.创建脚本

安装kickstart

yum install system-config-kickstart -y

启动图形界面

system-config-kickstart

修改配置文件

安装httpd

yum install httpd -y

systemctl enable --now httpd

ln -s /rhel7 /var/www/html/rhel7

测试

搭建DHCP服务

yum install dhcp -y

cp /usr/share/doc/dhcp*/dhcpd.conf.example /etc/dhcp/dhcpd.conf

vim /etc/dhcp/dhcpd.conf

systemctl enable --now dhcpd

搭建pxe网络安装环境

yum install syslinux.x86_64
yum install tftp-server.x86_64 -y  

systemctl enable --now tftp
netsat -antluple  

rpm -ql tftp-server 

cp /rhel7/isolinux/* /var/lib/tftpboot/
cp /usr/share/syslinux/pxelinux.0  /var/lib/tftpboot/

cd /var/lib/tftpboot/
mkdir pxelinux.cfg
cp isolinux.cfg pxelinux.cfg/default   

vim /etc/dhcp/dhcpd.conf

subnet 172.25.254.0 netmask 255.255.255.0 {
  range 172.25.254.30 172.25.254.40;
  option routers 172.25.254.2;
  next-server 172.25.254.200;  
  filename "pxelinux.0";   
}

systemctl restart dhcpd

vim /var/lib/tftpboot/pxelinux.cfg/default
