系统Centos 6.5 x86_64

ip:192.168.1.201

 

测试所需设备:(注意自己的dhcp网段修改,还有ip地址)

1.DHCP 服务器 

2.TFTP 服务器 

3.KickStart所生成的ks.cfg配置文件 

4.一台存放系统安装文件的服务器,如 NFS、HTTP 或 FTP 服务器,本文选择HTTP进行

5.带有一个 PXE 支持网卡的将安装的主机

 

 

1、安装相应的软件包

# yum install httpd tftp-server system-config-kickstart dhcpsyslinux -y

挂载CentOS6.5的DVD光盘,并复制第一张光盘下的所有内容到/var/www/html/centos6/

# mkdir -p /var/www/html/centos6

# mount -r /dev/cdrom /mnt

# cp -rf /mnt/* /var/www/html/centos6

 

2、配置tftp,启动http、tftp服务

# vim /etc/xinetd.d/tftp

# default: off

# description: The tftp server serves files using the trivial file transfer \

#protocol.The tftp protocol is often used to boot diskless \

#workstations, download configuration files to network-aware printers, \

#and to start the installation process for some operating systems.

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

}

 

3、配置dhcp

# vim /etc/dhcp/dhcpd.conf

#dhcpd.conf

optiondomain-name "cnlinux.com";

optiondomain-name-servers 114.114.114.114;

default-lease-time86400;

max-lease-time86400;

log-facilitylocal7;

subnet192.168.1.0 netmask 255.255.255.0 {

   range 192.168.1.240 192.168.1.250;

   option routers 192.168.1.1;

   filename "pxelinux.0";

   next-server 192.168.1.202;

}

 

4、配置支持PXE启动

# mkdir -p /tftpboot/pxelinux.cfg

# cp /usr/share/syslinux/pxelinux.0  /tftpboot/

# cd /mnt/images/pxeboot/;cp initrd.img vmlinuz /tftpboot

# cp /mnt/isolinux/boot.msg /tftpboot/

# cp /mnt/isolinux/vesamenu.c32  /tftpboot/

# cp /mnt/isolinux/splash.jpg /tftpboot/

# cp /mnt/isolinux/isolinux.cfg/tftpboot/pxelinux.cfg/default

# service dhcpd restart

# service xinetd restart

# service httpd restart

# chkconfig --level 35 httpd on

# chkconfig --level 35 dhcpd on

# chkconfig --level 35 xinetd on

 

关闭selinux

# setenforce 0

# sed -i "s@SELINUX=enforcing@SELINUX=disabled@g"/etc/sysconfig/selinux

 

 

关闭iptables

# /etc/init.d/iptables stop

# chkconfig iptables off

 

# vim /tftpboot/pxelinux.cfg/default

default linux

#prompt 1

timeout 600

display boot.msg

最后构建一台服务器,会自动装机。
