PXE-无人值守安装

无人值守网络安装LINUX操作系统

准备：

1、禁用防火墙、禁用SElinux、配置IP参数，

2、需要YUM环境

3、安装vsftp 启动服务

一、准备RHEL6安装源

[[email protected] ~]# mkdir /var/ftp/rhel6

[[email protected] ~]# mount /dev/cdrom /var/ftp/rhel6

[[email protected] ~]# service vsftpd start

二、安装启动TFPT服务器

[[email protected] ~]# yum -y install tftp-server

[[email protected] ~]# vim /etc/xinetd.d/tftp

Disable   = no

[[email protected] ~]# service xinetd start

三、准备LINUX内核、初始化镜像文件

[[email protected] ~]# cd /var/ftp/rhel6/images/pxeboot/

[[email protected] pxeboot]# cp vmlinuz initrd.img /var/lib/tftpboot/

四、准备PXE引导程序、启动菜单

[[email protected] pxeboot]# yum -y install syslinux

[[email protected] pxeboot]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

[[email protected] ~]# mkdir /var/lib/tftpboot/pxelinux.cfg

[[email protected] ~]# vim /var/lib/tftpboot/pxelinux.cfg/default

default auto

prompt 0

label auto

kernel vmlinuz

append ks=ftp://172.16.1.111/rhel6/ks.cfg initrd=initrd.img devfs=nomount ramdisk_size=8192

label linux text

kernel vmlinuz

append text initrd=initrd.img devfs=nomount ramdisk_size=8192

label linux rescue

kernel vmlinuz

append rescue initrd=initrd.img devfs=nomount ramdisk_size=8192

五、安装并启动DHCP服务

[[email protected] ~]# yum -y install dhcp

[[email protected] ~]# vim /etc/dhcp/dhcpd.conf

subnet 172.16.0.0 netmask 255.255.0.0 {

range 172.16.1.100 172.16.1.200;

option domain-name-servers 172.16.1.111;

option domain-name "benet.com";

option routers 172.16.1.1;

next-server 172.16.1.111;

filename "pxelinux.0";

filename "pxelinux.0";

}

[[email protected] ~]# service dhcpd restart

无人值守安装LINUX

一、配置安装应答参数

[[email protected] ~]# yum -y install system-config-kickstart

[[email protected] ~]# system-config-kickstart

B.复制并验证应答文件ks.cfg

[[email protected] ~]# cp /root/ks.cfg /var/ftp/ks.cfg

[[email protected] ~]# cat ks.cfg

C.测试结果

新建虚拟机无需设置BIOS从Network boot启动，将客户端的IP均设置为DHCP(自动获取方式)，即可。
