前言

在tftp那篇文章中我提到过一般网络安装基于Linux下PXE+TFTP+DHCP+(HTTP/FTP/NFS)来实现,然而在真实的生产环境中分别测试了Cloudboot和Cobbler,面对大量型号和配置不一样的物理机并不能满足实际需求。最后采用Windows笔记本+交换机+tftpd32+kickstart来灵活应对esxi6和rhel6.7的自动化装机,为了不依赖自动化光盘安装的低效懒人模式,中间还是踩了不少的坑。个人觉得装机并没有孰优孰劣的说法,而且未来是属于分布式存储+万兆交换机+类似VMware/OpenStack的模式,人肉装机的时代已经离我们渐行渐远。

利用tftpd32快速搭建自动化网络搞机平台

3点建议

  1. PXE只是网络安装的引导方式,自动化的核心配置文件始终依赖kickstart/autoyast/autounattend等
  2. 文章内提到的引导介质均提取自rhel6.7镜像文件syslinux-nonlinux-4.04-3.el6.noarch.rpm
  3. 云霁科技的Cloudboot成熟度非常高,建议大家多参考其高质量的配置方案

esxi

tftpd32+esxi6.0u2+kickstart+hfs

  1. Windows下关闭防火墙,设置IP地址为192.168.1.1/24
  2. 启动tftpd32参考上图所示配置,Base Directory目录选择实际定义的路径,如tftpboot_esxi\
  3. 解压ESXi ISO至tftpboot_esxi\,修改BOOT.CFG添加kernelopt=ks=http://192.168.1.1/esxi6/KS.CFG
  4. 将KS.CFG放入自定义目录,使用hfs加载
  5. 复制syslinux中的pxelinux.0到tftpboot_esxi\
  6. 复制syslinux中的MENU.C32替换tftpboot_esxi`中的同名文件
  7. 创建tftpboot_esxi\pxelinux.cfg\目录,复制ESXi ISO文件中的ISOLINUX.CFG至该目录并改名为default
  8. 检查tftpd32服务启动正常,测试自动化网络安装esxi

rhel

tftpd32+rhel6.7+kickstart+hfs

  1. Windows下关闭防火墙,设置IP地址为192.168.1.1/24
  2. 启动tftpd32参考上图所示配置,Base Directory目录选择实际定义的路径,如tftpboot_rhel\
  3. 解压rhel6.7 ISO至自定义目录,使用hfs作为http文件服务器
  4. 将ks.cfg放入自定义目录,使用hfs加载
  5. 复制syslinux中的pxelinux.0/initrd.img/vesamenu.c32/vmlinuztftpboot_rhel\
  6. 创建pxelinux.cfg目录,复制rhel6.7 ISO文件中的ISOLINUX.CFG至该目录并改名为default
  7. 修改default文件,ks=http://192.168.1.1/rhel67/ks.cfg ksdevice=eth10,出现multiple network devices提示一定要加入ksdevice确认网卡
  8. 检查tftpd32服务启动正常,测试自动化网络安装rhel

tftpd32

请允许我直接偷懒引用官方简洁纯朴的英文说明,希望大家在遇到问题前回顾下每个选项的解释,谢谢

Tftpd32 is a free, opensource IPv6 ready application which includes DHCP, TFTP, DNS, SNTP and Syslog servers as well as a TFTP client.

TFTP

Trivial File Transfer Protocol was first defined in 1980, it is a lightweight version of the FTP protocol that has no directory browsing or password capability. Employing UDP rather than TCP for transport, TFTP is typically used to transfer firmware upgrades to network equipment such as routers, switches and IP phones.It is also used to boot diskless computers (PXE).

SNTP

Simple Network Timle Protocol is a simplified version of NTP (Network Time Protocol). They synchronise the time on workstations across a network.

DHCP

DHCP assigns IP addresses to client stations logging onto a TCP/IP network. It eliminates having to manually assign permanent IP addresses on each station.

Syslog

Syslog is a service for remotely logging data. For example, it allows to monitor videoless network equipments.

Tftpd server Settings

Base directory
The default directory used by the TFTP client and server. It may be changed from the main window.

Global Settings
Enable or disable tftpd32 servers and clients.

TFTP security

  • NONE (Not recommended !)
    read and write requests are allowed on all disks/directories.
  • Standard
    read and write requests are allowed but limited to the current directory.
  • High
    idem standard + write requests are allowed only if the input file exists and is empty.
  • Read only
    idem standard + write requests are rejected.

TFTP Configuration

  • Timeout
    The maximum timeout between two retransmissions
  • Max Retransmit
    The maximum retransmission for the same packet
  • Tftp Port
    The port used to listen incoming requests
  • local ports pool
    A range of ports (for example 3000:3030). These ports are used for the file transfers.

TFTP Configuration

  • Option Negotiation
    Enables the negotiation between client and server (RFC 2347)
  • PXE compatibility
    Enables only the file size negotiation
  • Show progress Bar
    Creates a gauge window for each transfer
  • Translate Unix file names
    Translates any slash characters to a backslash
  • Bind Tftpd32 to this address
    Enables TFTP only on one interface
  • Allow ‘\’ As virtual root
    A file name beginning with ‘\’ points to the TFTP directory and not to the root of the disk
  • Use anticipation window of ??? bytes
    Tftpd32 is able to send packets before receiving acknowledgements. This feature may dramatically speed up the transfer.
  • Hide window at startup
    Tftpd32 main window remains hidden, but the icon in the tasktray is still present
  • Create dir.txt files
    For each incoming read request, Tftpd32 lists the content of the directory and put the result in a file named “dir.txt”.
  • Create md5 file
    For each successfull read request, Tftpd32 creates a file which is the MD5 signature of the previous file
    Beep for long transfer
    Tftpd32 sends a beep once a transfer has ended.

DHCP Setup

  • IP Pool starting Address
    This is the first address which will be distributed.
  • Size of pool
    This is the number of hosts which may be configured by Tftpd32.
  • Lease
    This is the amount of time in minutes the address is leased for.
  • Boot File
    Used by diskless stations. It is the file which will be retrieved by TFTP to start up the boot process.
    The strings $MAC$ and $IP$ are pseudo variables which are translated into the MAC address of the client and its assignated IP address.
  • Default router
    The IP address of the LAN gateway.
  • Mask
    The network mask which will be assigned to the DHCP clients.
  • DNS servers
    The IP address of the DNS. Two DNS can be configured.
  • WINS Server
    The IP address of the WINS server.
  • NTP Server
    The IP address of the NTP server used for synchronisation.
  • SIP Server
    The IP address of the SIP server. It concerns mostly IP phones.
  • Domain Name
    Either the NT domain or the internet domain.
  • Additional Option
    The first field is the number of the option to be handled
    The second filed is the value of the field. The value is prefixed with its type (a for list of IPv4 address, x for list of hex digits, b for list of decimal bytes, s for an ASCII string) [legacy prefixes: i for integer, n for network order integers]
  • More Additional Options ?
    Tftpd32 supports up to 10 additionnal options. They have to be configured by editing the tftpd32.ini settings file. Their syntax is similar to the previous one.
