PXE+DHCP+TFTP+Cobbler 無人值守安裝centos 7

準備 linu arch 機器 sage 語言 inpu 開機自啟動 第一個

Cobbler(補鞋匠)是通過將DHCP、TFTP、DNS、HTTP等服務進行集成,創建一個中央管理節點,其可以實現的功能有配置服務,創建存儲庫,解壓縮操作系統媒介,代理或集成一個配置管理系統,控制電源管理等。 Cobbler的最終目的是實現無需進行人工幹預即可安裝機器。

pxe概述
預啟動執行環境(Preboot eXecution Environment,PXE,也被稱為預執行環境)是讓計算機通過網卡獨立地使用數據設備(如硬盤)或者安裝操作系統

PXE Client發送廣播包請求DHCP分配IP地址DHCP
Server回復請求,給出IP地址以及Boot
Server的地址PXE下載引導文件執行引導程序

總結來說,

  pxe客戶端會調用網際協議(ip)、用戶數據報協議(udp)、動態主機設定協議(DHCP)、小型文件傳輸協議(TFTP)

  pxe客戶端(client)指機器在pxe啟動過程中的角色。一個pxe客戶端可以是一臺服務器、筆記本電腦或者其他裝有pxe啟動代碼的機器

  PXE主要是通過廣播的方式發送一個包,並請註獲取一個地址,而後交給TFTP程序下載一個引導文件。

cobbler和Kickstart批量裝機軟件

Cobbler由python語言開發,是對PXE和Kickstart以及DHCP的封裝。融合很多特性,提供了CLI和Web的管理形式。更加方便的實行網絡安裝。同時,Cobbler也提供了API接口,使用其它語言也很容易做擴展。它不緊可以安裝物理機,同時也支持kvm、xen虛擬化、Guest OS的安裝。更多的是它還能結合Puppet等集中化管理軟件,實現自動化的管理。

Kickstart 是一種無人值守的安裝方式,它的工作原理是在安裝過程中記錄人工幹預填寫的各種參數,並生成一個名為ks.cfg的文件。我們可以簡單理解為一個自動安裝應答配置管理程序。通過讀取這個配置文件,系統知道怎麽去分區,要安裝什麽包,配什麽IP,優化什麽內核參數等等

一句話總結:Cobbler補鞋匠是對Kickstart的封裝,簡化安裝步驟、使用流程,官方號稱補鞋匠都能學會的批量裝機。

Cobbler 工作流程

server端:

第一步,啟動Cobbler服務
第二步,進行Cobbler錯誤檢查,執行cobbler check命令
第三步,進行配置同步,執行cobbler sync命令
第四步,復制相關啟動文件文件到TFTP目錄中
第五步,啟動DHCP服務,提供地址分配
第六步,DHCP服務分配IP地址
第七步,TFTP傳輸啟動文件
第八步,Server端接收安裝信息
第九步,Server端發送ISO鏡像與Kickstart文件

Client端:

第一步,客戶端以PXE模式啟動
第二步,客戶端獲取IP地址
第三步,通過TFTP服務器獲取啟動文件
第四步,進入Cobbler安裝選擇界面
第五步,客戶端確定加載信息
第六步,根據配置信息準備安裝系統
第七步,加載Kickstart文件
第八步,傳輸系統安裝的其它文件
第九步,進行安裝系統

正式環境準備:

1.網絡環境:host-only、nat網絡,因為Cobbler需要用到自己的dhcp服務器,所以為了防止都在同一個網絡造成dhcp獲取混亂,需要切換網絡!~

2.類似安裝服務必要的環境準備:1,關閉iptables,selinux 2,配置靜態IP、設置主機名 並且在hosts文件下綁定 3.時間同步 4.配置本地iso鏡像裏的yum倉庫,163源epel源 (安裝軟件)

安裝完成,啟動軟件

[[email protected] ~]# systemctl restart cobblerd.service
[[email protected] ~]# systemctl restart httpd.service
[[email protected] ~]# systemctl enable cobblerd.service  //開機自啟動
Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service.
[[email protected] ~]# systemctl enable httpd.service  //開機自啟動
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

為什麽啟動apache?血的教訓,排了很久。不先啟動apache 後續cobbler check 報python file 的錯誤!!!

二.基本配置

[[email protected] ~]# cobbler check
The following are potential configuration items that you may want to fix:

1 : The ‘server‘ field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2 : For PXE to be functional, the ‘next_server‘ field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp
4 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run ‘cobbler get-loaders‘ to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely.  Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The ‘cobbler get-loaders‘ command is the easiest way to resolve these requirements.
5 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
7 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to ‘cobbler‘ and should be changed, try: "openssl passwd -1 -salt ‘random-phrase-here‘ ‘your-password-here‘" to generate new one
8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

Restart cobblerd and then run ‘cobbler sync‘ to apply changes.

一步步解決上述需求,部分需求可忽略。個體差異不同 每個人需求數量也不同,基本上大同小異

解決需求1、2、7
# openssl passwd -1 -salt ‘werwqerwqr‘ ‘123456‘ --123456為密碼(這是自動安裝客戶端系統成功後的root登錄密碼),werwqerwqr為隨機字節幹擾碼(隨便寫)
$1$werwqerw$.prcfrYFbwuvkD8XspayN.

# vim /etc/cobbler/settings
384 server: 192.168.100.221 --換成cobbler服務器端的IP
272 next_server: 192.168.100.221 --同上
101 default_password_crypted: "$1$werwqerw$.prcfrYFbwuvkD8XspayN." --把密碼字符串換成你上面產生的字符串(此密碼為客戶機安裝後的root登錄密碼)

解決需求3
# vim /etc/xinetd.d/tftp
disable = no --yes改為no

解決需求5

#systemctl restart rsyncd.service

#systemctl enable rsyncd.service

解決需求8
# yum install fence-agents

OK,剩下的需求像

4 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run ‘cobbler get-loaders‘ to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The ‘cobbler get-loaders‘ command is the easiest way to resolve these requirements.
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories

(問題4可以使用cobbler get-loaders解決,但需要有外網和外網的yum源 跳過,現在是NAT模式;問題6 是關於debian系統的,我們這裏可以忽略)

最後# systemctl restart cobblerd.service 重起下cobbler補鞋匠服務!

三.導入centos7.3的iso鏡像

我的環境iso鏡像掛載在/yum目錄,此拷貝步驟時間較長

# cobbler import --path=/yum/ --name=centos7.3

# cobbler distro list --導入成功後,確認導入的鏡像名
centos7.3-x86_64
# cobbler profile list --導入成功後,確認默認的profile名
centos7.3-x86_64

[[email protected] ~]# cobbler import --path=/yum/ --name=centos7.3

*** TASK COMPLETE ***


四.修改dhcp配置
# vim /etc/cobbler/dhcp.template  --在此文件的第21行到第25行修改成你對應的網段和ip

subnet 192.168.100.0 netmask 255.255.255.0 {
option routers 192.168.100.221;
option domain-name-servers 192.168.100.221;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.100.100 192.168.100.254;


--圖形的操作過程這裏省略後續還有這一步 重要

# vim /etc/cobbler/settings --再去修改這個配置文件,改成dhcp服務由cobbler來管理
242 manage_dhcp: 1 --把0改為1

# systemctl restart cobblerd.service --保存後,再重啟此服務

五.使用cobbler sync同步,並啟動xinetd服務

下面的cobbler sync 很重要,如果這步報錯一定要排出來,就經驗來說這步出錯一般是IP配置出錯,記得細心一點,個體差異不用就不詳細表述~

六.新建另一個虛擬機 選擇網絡安裝PXE (保證相同私有網絡,並且最好2G內存,內存小的話會在安裝時報空間不夠的錯誤),進行安裝測試

安裝完成後,更改boot引導

自動安裝我們已經實現了,但如何自定義我們想安裝的profile

重點就是你需要自定義一個ks文件


自定義ks文件的方法
1,如果你很熟悉此文件,直接拷別人的模版修改或者直接使用/root/anaconda-ks.cfg來修改
2,使用一個圖形工具system-config-kickstart來幫助你配置(下面我就是使用這種方法)


# yum install system-config-kickstart
# system-config-kickstart

--圖形的操作過程這裏省略


給大家兩個做好的ks.cfg文件參考:

第一個文件就是用來安裝centos7.3宿主機的ks文件,內容如下:
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Install OS instead of upgrade
install
# Keyboard layouts
keyboard ‘us‘
# Root password
rootpw --iscrypted $1$6RbFC2nC$GBugZL7ACuGhck8DbUZgM/
# Use network installation

# cobbler profile help --查看幫助
# cobbler profile list --查看有哪些profile
centos7.3-x86_64


# cobbler profile report --name=centos7.3-x86_64 |grep Kickstart
Kickstart : /var/lib/cobbler/kickstarts/sample_end.ks --這就是這個安裝方案的kickstart文件
Kickstart Metadata : {}


我現在自定義一個ks文件,也想做成一個profile,步驟如下:
步驟一:
自定義ks文件(使用system-config-kickstart或直接找一個模版文件修改),得到如下的文件

# vim /var/lib/cobbler/kickstarts/centos7.3.ks --復制下面一大段信息,粘到此文件裏

#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Install OS instead of upgrade
install
# Keyboard layouts
keyboard ‘us‘
# Root password
rootpw --iscrypted $1$6RbFC2nC$GBugZL7ACuGhck8DbUZgM/
# Use network installation
url --url="http://192.168.100.2/cobbler/ks_mirror/centos7.3/"

# Disk partitioning information
part /boot --fstype="xfs" --size=300
part swap --fstype="swap" --size=2000
part / --fstype="xfs" --grow --size=1


%post
rm /etc/yum.repos.d/* -rf
cat > /etc/yum.repos.d/local.repo << EOF
[base]

EOF

步驟二:把準備好的ks文件做成一個新的profile
# cobbler profile add --name=new_centos7.3 --distro=centos7.3-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7.3.ks

# cobbler profile list --在原來基礎上就多了自定義的安裝方案
centos7.3-x86_64
new_centos7.3


步驟三:
測試
然後就可以新建一個客戶端虛擬機,使用上面的new_centos7.3安裝名字來測試了



==================================================================

對上面操作的擴展(僅供參考)
# cobbler profile edit --name=new_centos7.3 --kickstart=/var/lib/cobbler/kickstarts/xxx.ks
# cobbler profile remove --name=new_centos7.3



======================================================================




客戶端使用koan與服務器的cobbler聯系,實現自動重裝系統

客戶端需要安裝koan軟件包(epel源裏就有)


# yum install koan
# koan --server=192.168.100.2 --list=profiles --192.168.100.2為cobbler服務器IP,得到的結果和在cobbler服務器上cobbler profile list命令得到的結果一樣
centos7.3-x86_64
new_centos7.3


# koan --replace-self --server=192.168.100.2 --profile=new_centos7.3 --指定本客戶端按照名為new_centos7.3的profile重裝系統

# reboot --敲完上面的命令,使用reboot,就會重裝了(沒敲上面的命令那reboot就是重啟)

寫文不易 且行且珍惜

這是一個二維碼
