利用arch配置一个pxe server,网络安装各种版本linux系统,各种版本windows系统!

想了半天也没有找到合适的板块发这个,最后还是发这里把!

最近折腾了两个小主机,华硕EeeBox B202,atom n270的u,1g的内存,80g的硬盘,机器挺小巧,就是单核u,功能实在鸡肋,索性一个做了个播放机,这个就做了一个pxe server!

利用wol的功能,网络装系统,至于pxe的原理,如下:


以下是摘自syslinux官网关于pxelinux的介绍,懒得翻译了,大家自己看,应该不难理解.
The basic configuration is the same for all Syslinux variants. This document explains only some of the differences specifically applicable to PXELINUX.
On the TFTP server, create the directory "/tftpboot", and copy "pxelinux.0" (from the Syslinux distribution) and any kernel or initrd images that you want to boot.
[5.00+] Also copy "ldlinux.c32" from the Syslinux distribution to the "/tftpboot" directory on the TFTP server.
Finally, create the directory "/tftpboot/pxelinux.cfg". The configuration file (equivalent of syslinux.cfg -- see the SYSLINUX FAQ for the options here) will live in this

directory.
Because more than one system may be booted from the same server, the configuration file name depends on the IP address of the booting machine.
Before a generic explanation, let's see first an example. When:
the bootloader file name is "/mybootdir/pxelinux.0"; and,
the client UUID is "b8945908-d6a6-41a9-611d-74a6ab80b83d"; and,
the Ethernet MAC address is "88:99:AA:BB:CC:DD"; and,
the IP address is "192.168.2.91", or in uppercase hexadecimal, "C0A8025B";
then PXELINUX will try the following configuration files (in this order):
/mybootdir/pxelinux.cfg/b8945908-d6a6-41a9-611d-74a6ab80b83d
/mybootdir/pxelinux.cfg/01-88-99-aa-bb-cc-dd
/mybootdir/pxelinux.cfg/C0A8025B
/mybootdir/pxelinux.cfg/C0A8025
/mybootdir/pxelinux.cfg/C0A802
/mybootdir/pxelinux.cfg/C0A80
/mybootdir/pxelinux.cfg/C0A8
/mybootdir/pxelinux.cfg/C0A
/mybootdir/pxelinux.cfg/C0
/mybootdir/pxelinux.cfg/C
/mybootdir/pxelinux.cfg/default
Let's see now what exactly the above example represents.
After attempting the file as specified in the DHCP or hardcoded options, PXELINUX will probe the following paths, prefixed with "pxelinux.cfg/", under the initial Working

Directory.
The client UUID, if provided by the PXE stack.
Note that some BIOSes do not have a valid UUID, and it might end up reporting something like all 1's.
This value is represented in the standard UUID format using lowercase hexadecimal digits, e.g. "b8945908-d6a6-41a9-611d-74a6ab80b83d".
The hardware type (using its ARP type code) and address, all in lowercase hexadecimal with dash separators.
For example, for an Ethernet (ARP type "1") with address "88:99:AA:BB:CC:DD", it would search for the filename "01-88-99-aa-bb-cc-dd".
The client's own IPv4 address in uppercase hexadecimal, followed by removing hex characters, one at a time, from the end. For example, "192.168.2.91" → "C0A8025B".
The included program, "gethostip", can be used to compute the hexadecimal IP address for any host.
Lowercase "default".


1:首先,需要的工具包有 dnsmasq,samba, nfs-utils,openssh,syslinux

dnsmasq   =    充当dhcp和tftpserver
samba      =    安装windows使用,另外也为了方便windows机器管理
nfs-utils    =    加载linux镜像用
openssh    =    管理用,ssh登录很方便,毕竟这台机器是个小的服务器吧
syslinux     =   启动pxelinux以及各种启动程序

arch下很简单,一条命令

pacman -S dnsmasq samba nfs-utils openssh syslinux

2:然后就是配置dhcp和tftp server,以及nfs 和 ssh server了


直接贴配置文件比较省事
dnsmasq为了配置方便,我在/etc/dnsmasq.d/重建了一个pxe.conf的配置文件,配置如下

记住要把/etc/dnsmasq.conf里面下面这句话取消注释


# Include another lot of configuration options.
#conf-file=/etc/dnsmasq.more.conf
conf-dir=/etc/dnsmasq.d


#     function as a tftp server 启动tftpserver
enable-tftp
#     root directory for files available via ftp. ftp的root环境
tftp-root=/tftpboot
#     the boot filename
#pxe-service=X86PC,"PXE Boot Menu",pxelinux 启动文件
dhcp-boot=/tftpboot/pxelinux.0
#     kill multicast
#dhcp-option=vendor:PXEClient,6,2b
#     disable reuse of the dhcp servername and filename fields as extra.
#     option space. to avoid confusing some old or broken dhcp clients.
dhcp-no-override
#     This range(s) is for the public interface, where dnsmasq functions
#     as a proxy DHCP server providing boot information but no IP leases.
#     Any ip in the subnet will do, so you may just put your server NIC ip here.
#     I used my router ip address
#dhcp-range=192.168.2.1,proxy,255.255.255.0

#dhcp-range=192.168.2.100,proxy
# do not give IPs that are in pool of DSL routers DHCP 我避开了家里路由器的dhcp缺省池
dhcp-range=192.168.2.151,192.168.2.200,12h
#     router/gateway ip address
dhcp-option=3,192.168.2.1
#     dns server ip address
dhcp-option=6,192.168.2.1
#     enable logging
log-dhcp
log-queries


samba的配置文件smb.conf
在windows下直接在文件浏览器中打入\\192.168.2.19,就可以打开tftpboot文件夹,直接管理里面的文件


# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#======================= Global Settings =====================================
[global]

# workgroup = NT-Domain-Name or Workgroup-Name
   workgroup = Workgroup

# server string is the equivalent of the NT Description field
   server string = Samba Server

# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page
;   hosts allow = 192.168.1. 192.168.2. 127.

;  smb passwd file = /etc/samba/smbpasswd

# The following are needed to allow password changing from Windows to
# update the Linux sytsem password also.
# NOTE: Use these with 'encrypt passwords' and 'smb passwd file' above.
# NOTE2: You do NOT need these to allow workstations to change only
#        the encrypted SMB passwords. They allow the Unix password
#        to be kept in sync with the SMB password.
;  unix password sync = Yes
;  passwd program = /usr/bin/passwd %u

# If you have multiple network interfaces then you must list them
# here. See the man page for details.

;   local master = no

# OS Level determines the precedence of this server in master browser
# elections. The default value should be reasonable
;   os level = 33

# Domain Master specifies Samba to be the Domain Master Browser. This
# allows Samba to collate browse lists between subnets. Don't use this
# if you already have a Windows NT domain controller doing this job
;   domain master = yes
    domain master = auto

# Preferred Master causes Samba to force a local browser election on startup
# and gives it a slightly higher chance of winning the election
;   preferred master = yes

# Use only if you have an NT server on your network that has been
# configured at install time to be a primary domain controller.
;   domain controller =

# Enable this if you want Samba to be a domain logon server for
# Windows95 workstations.
;   domain logons = yes

# if you enable domain logons then you may want a per-machine or
# per user logon script
# run a specific logon batch file per workstation (machine)
;   logon script = %m.bat
# run a specific logon batch file per username
;   logon script = %U.bat

# Where to store roving profiles (only for Win95 and WinNT)
#        %L substitutes for this servers netbios name, %U is username
#        You must uncomment the [Profiles] share below
;   logon path = \\%L\Profiles\%U

# All NetBIOS names must be resolved to IP Addresses
# 'Name Resolve Order' allows the named resolution mechanism to be specified
# the default order is "host lmhosts wins bcast". "host" means use the unix
# system gethostbyname() function call that will use either /etc/hosts OR
# DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf
# and the /etc/resolv.conf file. "host" therefore is system configuration
# dependant. This parameter is most often of use to prevent DNS lookups
# in order to resolve NetBIOS names to IP Addresses. Use with care!
# The example below excludes use of name resolution for machines that are NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.
; name resolve order = wins lmhosts bcast

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server
;   wins support = yes

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
;   wins server = w.x.y.z

# WINS Proxy - Tells Samba to answer name resolution queries on
# behalf of a non WINS capable client, for this to work there must be
# at least one WINS Server on the network. The default is NO.
;   wins proxy = yes

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups. The built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.
   dns proxy = no

# Case Preservation can be handy - system default is _no_
# NOTE: These can be set on a per share basis
;  preserve case = no
;  short preserve case = no
# Default case is normally upper case for all DOS files
;  default case = lower
# Be very careful with case sensitivity - it can break things!

nfs的配置文件 exports


# /etc/exports - exports(5) - directories exported to NFS clients
#
# Example for NFSv2 and NFSv3:
#  /srv/home        hostname1(rw,sync) hostname2(ro,sync)
# Example for NFSv4:
#  /srv/nfs4    hostname1(rw,sync,fsid=0)
#  /srv/nfs4/home   hostname1(rw,sync,nohide)
# Using Kerberos and integrity checking:
#  /srv/nfs4        *(rw,sync,sec=krb5i,fsid=0)
#  /srv/nfs4/home   *(rw,sync,sec=krb5i,nohide)
#
# Use `exportfs -arv` to reload.
#/tftpboot/images/ARCH_201510/ 192.168.2.0/24(ro,no_subtree_check)
/tftpboot/images/ARCH_201510/  *(ro,no_subtree_check,async,no_root_squash)
/tftpboot/images/kali2/         *(ro,no_subtree_check,async,no_root_squash)


3:接着配置tftpboot主目录

makdir /tftpboot/{images,iso,syslinux,pxelinux.cfg}

其中images文件夹是挂载的linux安装镜像和windows安装镜像

iso文件夹里是我各种安装iso文件的收集地点

syslinux文件夹里是syslinux各种模块的收藏地点

pxelinux.cfg目录里存放着pxelinux的启动配置文件,也就是目录文件

然后把各种pxelinux启动相关的文件,拷贝入tftpboot目录,和syslinux目录


cp /usr/lib/syslinux/bios/pxelinux.0  /tftpboot/
cp   /usr/lib/syslinux/bios/{chain.c32,hdt.c32,ldlinux.c32,libcom32.c32,libgpl.c32,libmenu.c32,libutil.c32,poweroff.c32,reboot.c32,vesamenu.c32} /tftpboot/syslinux/

其中
pxelinux.0是启动文件,hdt是用来显示机器的各种配置的,chain.c32是用来启动本地硬盘的,lib文件都是各种库,poweroff和reboot大家都懂的.

最后就是/tftpboot/pxelinux.cfg/default配置文件的内容了,这个内容是根据我的机器挂载的镜像修改的

期间还自己学会了自制winpe,我做了2个版本的winpe,一个32位,一个64位.


最后,只要把要安装的机器修改为网卡启动,就可以进入我配置的pxe server了
