pxe配合kickstart无人值守批量装机

图文详解部分请看PXE配合Kickstart无人值守——批量装机简单如喝水（详细）

一、shell脚本一键桌面化装机

#!/bin/bash
#检测是否挂载
df | grep "sr0" &> /dev/null
if [ $? -eq 0 ];then
echo "磁盘已挂载"
else
mount /dev/sr0 /mnt &> /dev/null
fi

#安装并启动TFTP：tftp-server xinetd 
yum -y install tftp-server xinetd &> /dev/null

#修改tftp服务的配置文件：/etc/xinetd.d/tftp
sed -i 's/yes/no/g' /etc/xinetd.d/tftp
systemctl start tftp
systemctl enable tftp
systemctl start xinetd
systemctl enable xinetd

#安装dhcp
yum -y install dhcp &> /dev/null

#修改dhcp配置文件
cat /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example > /etc/dhcp/dhcpd.conf
echo 'ddns-update-style none;
next-server 192.168.184.30;
filename "pxelinux.0";' >> /etc/dhcp/dhcpd.conf

echo   'subnet 192.168.184.0 netmask 255.255.255.0 {

option routers 192.168.184.30;
}' >> /etc/dhcp/dhcpd.conf
systemctl restart dhcpd
systemctl enable dhcpd

#准备linux内核、初始化镜文件

#准备pxe引导程序

#安装ftp服务，准备centos7安装源

mkdir /var/ftp/centos7              #在ftp根目录下创建目录centos7
cp -rf /mnt/* /var/ftp/centos7/     #将镜像文件强制复制到centos7目录中，可加&让它自己后台运行
systemctl start vsftpd              #开启vsftpd服务
