pxe 網路開機

2007-06-07 @ 19:51 in Linux

最近突想做pc的網路開機,整整再google找了兩,三天,總算有幾篇教導利用 pxelinux 做開機的方式,我的做法如下

  1. 主機 fedora5
  2. 安裝 tftp-server => 修改 /etc/xinetd.d/tftp =>將 disable = no
  3. 安裝 dhcp => 修改 dhcpd.conf 如下
    server-identifier 10.0.0.254;   #在多張網路卡的時候可以加上﹐可不設
    allow booting;                      #將 dhcp 提供 bootp; 
    allow bootp;                        #將 dhcp 提供 bootp;
    option domain-name "fhsh.tp.edu.tw";
    option domain-name-servers 168.95.1.1,168.95.192.1,10.0.0.254;
    default-lease-time 3600;
    max-lease-time 7200;
    authoritative;
    ddns-update-style none;
    log-facility local7;                  #加這三行
    server-name "PXE Server";
    server-identifier 10.0.0.254;
    subnet 10.0.0.0 netmask 255.255.0.0 {
        range 10.0.0.50 10.0.0.250;
        range 10.0.1.50 10.0.1.250;
        option routers 10.0.0.254;
        option broadcast-address 10.0.255.255;
        filename "pxelinux.0";          #從  tftp 下載執行檔  
        next-server 10.0.0.254;      # tftp 的 ip 位置
    }
  4. 抓下pxelinux工具  http://syslinux.zytor.com/download.php
    主要是用到裡面的pxelinux.0、memdisk和menu.c32,將這些檔案放到tftp的根目錄下
  5. * 修改 tftp目錄下的 pxelinux.cfg/default,第一次需先建立目錄與檔案,範例如下
    DEFAULT menu.c32 '預設以menu.c32這個核心來啟動,即出現選單
    PROMPT 0 '不要用prompt的方式,即啟用選單
    ALLOWOPTIONS 0 '不要該使用者有選擇權,例如更改啟動參數或直接離開選單
    TIMEOUT 50 '選單的提示時間,50好像是指5秒

    MENU TITLE PXELinux Menu '選單的標題

    LABEL freebsd54 '名稱
    MENU LABEL BSD '選單上的標題
    kernel memdisk '用來啟動影像檔的核心,pxelinux提供
    append initrd=fbsd54.img c=812 h=255 s=63 '要載入的影像檔及參數,此例為將bsd的bootonlyCD所做成的PXE影像檔

    LABEL local
    MENU DEFAULT LOCAL ' MENU DEFAULT 是預設選單指向
    LOCALBOOT 0 ' 直接以硬碟開機

    LABEL dos
    MENU LABEL DOS
    kernel memdisk
    append initrd=dos.img ' 將磁片做成影像檔後,直接放進來就可以用了,不用加參數,下面的也都是直接用磁片所做成的影像檔

    LABEL ghost2003
    MENU LABEL ghost2003
    kernel memdisk
    append initrd=ghost2003.img
  6. 我喜歡這種方式,可以依照自己喜歡增加開機選單,利用 gohot 做開機檔,再利用 linux 的 dd 指令,做成 img ,真方便
    dd if=/dev/fd0 of=ghost2003.img
  7. 如果 dhcp 用 windows 只要將它設定 bootp與dhcp都提供,再增加 66,67兩項選項的設定
    在 dhcp =>內容=>進階=>勾選 只有BOOTP 或 兩者都可以
    在 dhcp=>伺服器選項=>設定選項=>66 填入 tftp 主機 ip =>67 填入tftp給 pc 的啟動檔,這裹是
    pxelinux.0
  8. 以後採購電腦一定要求網卡有支援 pxe 網路開機功能才方便

Hello! I know this is somewhat off-topic but I needed to ask.
Does managing a well-established website such as yours take a
large amount of work? I'm completely new to operating a blog
but I do write in my journal everyday. I'd like to start a blog so I
will be able to share my personal experience and feelings online.
Please let me know if you have any kind of suggestions or tips for new
aspiring blog owners. Appreciate it!

Howdy! I know this is somewhat off topic but I
was wondering if you knew where I could find a captcha plugin for my comment form?
I'm using the same blog platform as yours and I'm having
difficulty finding one? Thanks a lot!

I'm curious to find out what blog system you have been working
with? I'm having some minor security problems with my latest website and
I'd like to find something more secure. Do you have any solutions?

I have certainly picked up something new from right here.
I did however expertise a few technical issues using this web site, as I experienced to reload
the site many times previous to I could get it to load properly.
I had been wondering if your web hosting is OK?

Not that I'm complaining, but sluggish loading instances times will often affect your placement
in google and could damage your quality score if ads and marketing with Adwords.

Well I'm adding this RSS to my email and can look out for
much more of your respective exciting content.
