本文主要包含pxe kickstart,pxe dhcp,pxe,pxe启动,pxe是什么意思等服务器相关知识,网友希望可以进行参考
(1)安装所需软件，搭建环境：
#yum -y install httpd tftp-server dhcp system-config-kickstart
挂载光盘文件，将其他机器装机所需软件的复制到/var/www/html：一定要放在Apache的运行目录下）
#mkdir /media/cdrom
#mount -o -loop CentOS-6.3.iso /media/cdrom
#cp -fr /media/cdrom /var/www/html/
(2)相关配置：
TFTP配置——修改/etc/xinetd.d/tftp文件：
接着修改/etc/xinetd.d/tftp文件，将disable的值由yes变为no，内容如下所示：
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
.接着重启xinetd进程，命令如下所示：
service xinetd restart
DHCP配置——修改/etc/dhcp/dhcpd.conf:
cp -p /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
vim /etc/dhcp/dhcpd.conf
# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#
subnet 192.168.1.0 netmask 255.255.255.0 {
default-lease-time 21600;
max-lease-time 43200;
range 192.168.1.210 192.168.1.230;
option subnet-mask 255.255.255.0;
next-server 192.168.1.228;
filename "/pxelinux.0";
}
(3)配置支持PXE的启动程序——
#cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot
#cp /var/www/html/images/pxeboot/initrd.img /var/lib/tftpboot
#cp /var/www/html/images/pxeboot/vmlinuz /var/lib/tftpboot
#cp /var/www/html/isolinux/*.msg /var/lib/tftpboot
#mkdir /var/lib/tftpboot/pxelinux.cfg
#cp /var/www/html/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
终端运行kickstart
#system-config-kickstart
ks.cfg:

修改此default文件：
vim /var/lib/tftpboot/pxelinux.cfg/default
第1行改为：default linux对应就是下面的label linux）
timeout 600改为timeout 1，这样可以立马进入装机，不用等待。
label linux
menu label ^Install or upgrade an existing system
menu default
kernel vmlinuz
append initrd=initrd.img 后添加一个:ks=http://192.168.x.x/ks.cfg
重启服务器 关闭防火墙
service httpd restart
service xinetd restart
service dhcpd restart
service iptables stop本文出自 “超級無敵小小遜” 博客，请务必保留此出处http://xunzhang.blog.51cto.com/7808213/1297809
