网络启动二：之PXE：企业应用

网络启动二：之PXE：企业应用

前几天写了IPXE简单应用内容，今天详细介绍使用PXE在企业中的应用，部署Linux系统和Windows系统。

一、搭建环境

1.1.操作系统：CentOS6.9 Min  /  CentOS7.4 Min  172.16.30.59

    安装文件存放服务器 http://172.16.30.121  目录有centos6.9 centos7.3 ubuntu16 eg..

    安装过程略。

1.2.安装 tftp-server dhcp

sudo yum install tftp-server dhcp

1.3.配置tftp和dhcp

1.3.1.dhcp

vi /etc/dhcp/dhcpd.conf

-------------------------------

echo "option space PXE;

option PXE.mtftp-ip    code 1 = ip-address;

option PXE.mtftp-cport code 2 = unsigned integer 16;

option PXE.mtftp-sport code 3 = unsigned integer 16;

option PXE.mtftp-tmout code 4 = unsigned integer 8;

option PXE.mtftp-delay code 5 = unsigned integer 8;

option client-system-arch code 93 = unsigned integer 16;

#option domain-name-servers 8.8.8.8, 195.235.96.90;

allow booting;

allow bootp;

default-lease-time 600;

max-lease-time 7200;

#ddns-update-style interim;

subnet 172.16.30.0 netmask 255.255.255.0 {

  range 172.16.30.50 172.16.30.70;

  option routers 172.16.30.59;

 class "pxeclients" {

        match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";

        next-server 172.16.30.59;

        if option client-system-arch = 00:07 or option client-system-arch = 00:09 {

         #filename "pxelinux/BOOTX64.efi";

         filename "pexlinux/efi64/syslinux.efi";

        } else {

         filename "pxelinux/pxelinux.0";

         #filename "pxelinux/BOOTX64.efi";

        }

   }

  #server-name "pingu";

  #next-server 172.16.30.100;

}

" >>/etc/dhcp/dhcpd.conf

-------------------

chkconfig --level 345 dhcpd on

service start dhcpd

1.3.2.tftp

1.修改tftp配置文件

echo "in.tftpd: 172.16.*.* :ALLOW" >>/etc/hosts.allow

sed -i '/disable/s/yes/no/' /etc/xinetd.d/tftp

service start xinetd

基础环境完毕，下一步安装syslinux,此处我们不采用CentOS安装盘里面的软件包，而采用官网最新包。

1.4官方网站syslinux

http://www.syslinux.org/

https://www.kernel.org/pub/linux/utils/boot/syslinux/Testing/6.04/syslinux-6.04-pre1.tar.gz

下载最新版本即可，目前为syslinux6.04

文件下载位置 /home/yluser/

1.3.安装依赖包

官方指定的依赖包

sudo yum install perl gcc nasm libuuid-devel

cd /home/yluser

tar zxvf syslinux-6.04-pre1.tar.gz

cd syslinux-6.04

具体编译情况，请查阅syslinux-6.04/doc/building.txt文档，

make 默认编译所有类型。

make

sudo make install

默认安装位置/usr/share/syslinux

根据dhcp的配置tftp目录，拷贝以下文件到指定目录

mkdir -p /var/lib/tftpboot/pxelinux/{pxelinux.cfg,centos7,centos6,ubuntu16,esxi6,win7,win10,winserver}

cp /usr/share/syslinux/{pxelinux.0,menu.c32,vesamenu.c32,memdisk,ldlinux.c32,libutil.c32,libcom32.c32} /var/lib/tftpboot/pxelinux

cp -R /usr/share/syslinux/{efi32,efi64} /var/lib/tftpboot/pxelinux

wget http://172.16.30.121/centos7.4/isolinux/splash.png -P /var/lib/tftpboot/pxelinux

wget http://172.16.30.121/centos7.4/isolinux/{initrd.img,vmlinuz} -P /var/lib/tftpboot/pxelinux/centos7.4

wget http://172.16.30.121/centos6.9/isolinux/{initrd.img,vmlinuz} -P /var/lib/tftpboot/pxelinux/centos6

vi pxelinux.cfg/default

------------------------

  menu label ^Centos6.9 Min

  menu default

  kernel centos6/vmlinuz

  append initrd=centos6/initrd.img ip=dhcp repo=http://172.16.30.121/centos6.9 ks=http://172.16.30.121/kickstarts/Centos-6.x-min.cfg ksdevice=eth1

label linux

  menu label ^Centos7.4 Min

  kernel centos7.4/vmlinuz

  append initrd=centos7.4/initrd.img ip=dhcp repo=http://172.16.30.121/centos7.4 ks=http://172.16.30.121/kickstarts/Centos-7.x-min.cfg

label linux

  menu label ^Windows 10

  kernel memdisk raw iso

  append initrd=win10/W10X32_CN_PE.iso

-----------------------

具体配置参数，请参考syslinux官网文档，或与我联系。

以上步骤即可成功部署Windows或者Linux、Esxi。
