测试环境:win10/vmware workstation 12 pro

操作系统:RHEL 6.5(PXE服务器)

【2016.11.30】

 

【遗留问题】

1、ks.cfg通过本地文件方式加载不成功,只能通过http://方式成功 ,以下几种尝试都是不成功的。

   ks=file:esxi5.1/ks.cfg
   ks=ks.cfg
   ks=tftp://192.168.148.1/esxi5.1/ks.cfg

 

 

安装与配置:


 。安装DHCP

。安装XINETD, 并启用TFTP服务

。安装syslinux(yum安装):会自动在tftpboot目录下放置pxelinux.0及seamenu.c32文件,还有一些其它文件

 

配置DHCP: 在地址分配子项中增加filename "pxelinux.0"

配置tftp: enable一下即可,无其它特殊配置,无需-c,整个过程不会向tftp写文件

配置菜单:在tftpboot目录下,创建一个文件夹:pxelinux.cfg。然后再建立default文件,即菜单文件

 

配置好之后,就可以启动一台PXE客户端进行测试了,正常情况下,就可以显示菜单了。说明PXE配置成功了,接下来就可以根据实际安装需求,定制default文件、制定ks.cfg文件及布署安装包了。

 

 利用PXE方式安装ESXi 5.1


参考文档:主要是vmware的官方文档 

准备:

  • 下载ESXi 5.1的ISO安装包,并在tftpboot下建立目录esxi5.1
  • 将iso文件解开后,将文件copy至esxi5.1下(不能只接将ISO mount到esxi5.1目录,因为要修改文件) 

 配置:

     pxelinux.cfg/default文件: (可以将esxi5.1中的isolinux.cfg文件COPY过来进行修改,主要修改为正确的目录路径)

default menu.c32
menu title PXE BOOT VMWARE ESXI
timeout 100

label ESXi
menu label Boot VMware ESXi
  kernel esxi5.1/mboot.c32
  append -c esxi5.1/boot.cfg     //注意此处boot.cfg要修改
  menu label esxi5.1-xxxxxx

//整个文件相对简单,只是增加了相对目录esxi5.1

 

  esxi5.1/boot.cfg文件:由于原ISO是光盘模式的,故每个文件都给出了绝对路径/(根) 

[root@localhost esxi5.1]# cat boot.cfg
bootstate=0
title=Loading ESXi installer
kernel=/tboot.b00
kernelopt=runweasel
modules=/b.b00 --- /useropts.gz --- /k.b00 --- /chardevs.b00 --- /a.b00 --- /user.b00 --- /s.v00 --- /ata_pata.v00 --- /ata_pata.v01 --- /ata_pata.v02 --- /ata_pata.v03 --- /ata_pata.v04 --- /ata_pata.v05 --- /ata_pata.v06 --- /ata_pata.v07 --- /block_cc.v00 --- /ehci_ehc.v00 --- /weaselin.t00 --- /esx_dvfi.v00 --- /xlibs.v00 --- /ima_qla4.v00 --- /ipmi_ipm.v00 --- /ipmi_ipm.v01 --- /ipmi_ipm.v02 --- /misc_cni.v00 --- /misc_dri.v00 --- /net_be2n.v00 --- /net_bnx2.v00 --- /net_bnx2.v01 --- /net_cnic.v00 --- /net_e100.v00 --- /net_e100.v01 --- /net_enic.v00 --- /net_forc.v00 --- /net_igb.v00 --- /net_ixgb.v00 --- /net_nx_n.v00 --- /net_r816.v00 --- /net_r816.v01 --- /net_s2io.v00 --- /net_sky2.v00 --- /net_tg3.v00 --- /net_vmxn.v00 --- /ohci_usb.v00 --- /sata_ahc.v00 --- /sata_ata.v00 --- /sata_sat.v00 --- /sata_sat.v01 --- /sata_sat.v02 --- /sata_sat.v03 --- /sata_sat.v04 --- /scsi_aac.v00 --- /scsi_adp.v00 --- /scsi_aic.v00 --- /scsi_bnx.v00 --- /scsi_fni.v00 --- /scsi_hps.v00 --- /scsi_ips.v00 --- /scsi_lpf.v00 --- /scsi_meg.v00 --- /scsi_meg.v01 --- /scsi_meg.v02 --- /scsi_mpt.v00 --- /scsi_mpt.v01 --- /scsi_mpt.v02 --- /scsi_qla.v00 --- /scsi_qla.v01 --- /scsi_rst.v00 --- /uhci_usb.v00 --- /tools.t00 --- /xorg.v00 --- /imgdb.tgz --- /imgpayld.tgz
build=
updated=0

  

 但由于我们采用PXE方式,文件不再位于根,而是位于tftp服务器的esxi5.1目录下,因此,需要将所有/替换成esxi5.1/xxx。操作如下:

首先,将所有/都替换掉,VI命令:%s#/##g

然后在modules这行前面加入一行:prefix=esxi5.1/ (这条命令全局有效,不在乎所在位置)

“kernel=......”一行为 kernel=tboot.b00,此处不加esxi5.1/

 

启动pxe client测试:

通过上面设置后,启动PXE CLIENT,基本就能出现安装界面了,只需要选择键盘、安装位置,基本没什么选项(问题:在何处加载第三方驱动)。

这种方法只是实现了PXE安装,但没有实现无人值守的自动安装。

 

ESXi 5实现全自动安装(无需人工连接键盘、显示器):这里要用到ks.cfg文件(kickstart)


就增加两个步骤:1)生成ks.cfg    2)在default文件中传递该ks.cfg文件给核心

任何一台esxi安装完成后,会自动生成一个etc/vmware/weasel/ks.cfg,可通过修改这个文件定制必要的参数,实验中采用了如下ks.cfg

#
# Sample scripted installation file
#
# Accept the VMware End User License Agreement
vmaccepteula
# Set the root password for the DCUI and Tech Support Mode
rootpw iampeter319
# The install media is in the CD-ROM drive
install --firstdisk --overwritevmfs
# Set the network to DHCP on the first network adapater
#network --bootproto=dhcp --device=vmnic0
network --bootproto=static --device=vmnic0 --ip=192.168.148.100 --netmask=255.255.252.0 --gateway=192.168.148.1
reboot
# A sample post-install script
%post --interpreter=python --ignorefailure=true
import time
stampFile = open('/finished.stamp', mode='w')
stampFile.write( time.asctime() )

具体参数及语法,可参考vmware官方文档。这里只改了network项及安装完成后自动reboot。

准备好ks.cfg文件后,需要将其位置传递给核心,可以通过protocol:// , cdrom://, file://, usb://等方式。在实验中,采用file方式没有成功,原因不详。最后采用http://<PXESERVER_IP>/ks.cfg的方式(即将ks.cfg拷贝至apache的/var/www/html目录下)

按照官方文档的说明,应该是修改boot.cfg文件,通过kernelopt=ks=http://xxxx/ks.cfg进行传递。但感觉这样不方便,未采用,而采用了修改default文件的方法,效果一样。

修改原boot.cfg文件中的倒数第二行,更改为如下:

 append -c esxi5.1/boot.cfg ks=http://192.168.148.128/ks.cfg

还有一种特殊的做法:ESXi在启动成功后,会在其虚拟文件系统中产生一个/etc/vmware/weasel/ks.cfg文件。如果我们传递如下格式: 

ks=file://etc/vmware/weasel/ks.cfg

则ESXi也会自动安装,但是参数是不受控制的,因为是自动生成的。这种方式安装完成后,密码空,IP地址为自动获取。

【说明】在生成ks.cfg文件后,可以不修改default文件进行传递,而是在ESXi开始安装时,通过按Shift-O键,手工进行传递,之后就会自动进行了。

由于ks的内容较多,以下是两个例子,比较全面,全自动安装并且自动设置包括:网络、SSH、vSwitch等等

【关于ipv6】上面有两种方法可以disable掉IPV6。但是esxcli的重启语句需要先进入维护模式才能执行。也可以简单的在%firstboot的最后加一行reboot,直接重启。

采用http方式:


 

前面介绍的方法,文件的抓取都是通过tftp方式。在网络环境不佳的情况下,tftp 采用的udp方式没有http的tcp方式稳定。根据vmware官方文档,可采用http方式代替tftp方式

1、pxelinux.0是tftp方式;gpxelinux.0是http方式,因此,更改dhcp.conf的filename "gpxelinux.0"

2、修改boot.cfg,将prefix=esxi5.1/;改为: http://x.x.x.x/esxi5.1/

3、相应的文件夹做好链接,并用浏览器做好测试,就可以执行http的安装了。

 

Windows平台PXE的实现


 windows平台下要实现pxe,也需要dhcp,tftp,(option)http。tiny pxe server 1.0版可以实现该功能。它不仅内置了tftp,dhcp,http,而且内置了pxelinux.0及gpxelinux,软件仅有不到5M。

需要注意:所有服务器的根是files目录,其它的和linux下是一样的。在进行esxi安装时,配置文件需要linux格式,特别是ks文件。如果格式不是linux格式(unix,ansi)而是windows文本格式,就会出现许多莫名其妙的问题。

 

工作流程分析(根据抓包结果得出):


1.DHCP: 分配IP地址,并分配pxelinux.0文件名告之PXE client
2. Client通过tftp拿到pxelinux.0,大约19个blocks
3. Client运行pxelinux.0, 准备拿配置文件
4. 连续tftp几个文件(由于只配置了default,肯定找不到),pxelinux.cfg目录下

564d330d-5a45-e2de-eb15-88e321e7dfd2 【未知】
01-00-0c-29-e7-df-d2 【此文件名是01,加上PXE CLIENT主机的MAC地址,可采用这种方式进行个性化定制】
C0A89464 【此为该主机的IP地址(192 168 148 100)的十六进制表示,下面类同,这样可以实现针对不同主机或一类主机的定制化配置】
C0A8946
C0A894
C0A89
C0A8
C0A
C0
C

以上文件没有配置,最后取得default文件。Default文件如下:

default vesamenu.c32
timeout 100

menu background splash.jpg
menu title Welcome to Install System --BY Lvyun
 
label Auto_CentOS
menu label Auto Install CentOS6.2
menu default
kernel CentOS/vmlinuz
append initrd=CentOS/initrd.img ks=nfs:192.168.2.58:/mnt/ks/ks.cfg

label Custom_CentOS
menu label Custom Install CentOS6.2
kernel CentOS/vmlinuz

  

5. 成功后,client再读取default文件,得知要用vesamenu.c32, 则继续tftp,取vesamenu.c32,大约117blocks
6. Client取到相应的menu.c32,就在client上运行,client根据之前拿到的default显示菜单

 

Troubleshooting:


1. pxe client DHCP成功,但是tftp.....报错

    pxe服务器的iptables没有关掉(与宿主windows的防火墙无关)

2. DHCP成功,tftp也能拿到pxelinux.0,但就是拿不到default,提示权限问题。在tftp服务器上手工tftp get default文件,也说是权限问题不能拿到。

   原因:selinux关闭就好了。
