PXE+DHCP+TFTP+Cobbler 無人值守安裝centos 7
Cobbler(補鞋匠)是經過將DHCP、TFTP、DNS、HTTP等服務進行集成，建立一箇中央管理節點，其能夠實現的功能有配置服務，建立存儲庫，解壓縮操做系統媒介，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干預便可安裝機器。java
pxe概述
預啓動執行環境（Preboot eXecution Environment，PXE，也被稱爲預執行環境)是讓計算機經過網卡獨立地使用數據設備(如硬盤)或者安裝操做系統
PXE Client發送廣播包請求DHCP分配IP地址DHCP
Server回覆請求，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
總結來講，python
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)linux
pxe客戶端（client）指機器在pxe啓動過程當中的角色。一個pxe客戶端能夠是一臺服務器、筆記本電腦或者其餘裝有pxe啓動代碼的機器web
PXE主要是經過廣播的方式發送一個包，並請注獲取一個地址，然後交給TFTP程序下載一個引導文件。shell
cobbler和Kickstart批量裝機軟件apache
Cobbler由python語言開發，是對PXE和Kickstart以及DHCP的封裝。融合不少特性，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作擴展。它不緊能夠安裝物理機，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。json
Kickstart 是一種無人值守的安裝方式，它的工做原理是在安裝過程當中記錄人工干預填寫的各類參數，並生成一個名爲ks.cfg的文件。咱們能夠簡單理解爲一個自動安裝應答配置管理程序。經過讀取這個配置文件，系統知道怎麼去分區，要安裝什麼包，配什麼IP，優化什麼內核參數等等 vim
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。centos
Cobbler 工做流程api
server端：
第一步，啓動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，複製相關啓動文件文件到TFTP目錄中
第五步，啓動DHCP服務，提供地址分配
第六步，DHCP服務分配IP地址
第七步，TFTP傳輸啓動文件
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模式啓動
第二步，客戶端獲取IP地址
第三步，經過TFTP服務器獲取啓動文件
第四步，進入Cobbler安裝選擇界面
第五步，客戶端肯定加載信息
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，由於Cobbler須要用到本身的dhcp服務器，因此爲了防止都在同一個網絡形成dhcp獲取混亂，須要切換網絡!~
2.相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 而且在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，啓動軟件
[root@bokeyuan ~]# systemctl restart cobblerd.service
[root@bokeyuan ~]# systemctl restart httpd.service
[root@bokeyuan ~]# systemctl enable cobblerd.service //開機自啓動
Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service.
[root@bokeyuan ~]# systemctl enable httpd.service //開機自啓動
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
爲何啓動apache？血的教訓，排了好久。不先啓動apache 後續cobbler check 報python file 的錯誤！！！
二.基本配置
[root@bokeyuan ~]# 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。個體差別不一樣 每一個人需求數量也不一樣，基本上大同小異
解決需求一、二、7
# openssl passwd -1 -salt 'werwqerwqr' '123456' --123456爲密碼(這是自動安裝客戶端系統成功後的root登陸密碼）,werwqerwqr爲隨機字節干擾碼（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(此密碼爲客戶機安裝後的root登陸密碼)
解決需求3
# vim /etc/xinetd.d/tftp
disable = no --yes改成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可使用cobbler get-loaders解決，但須要有外網和外網的yum源 跳過，如今是NAT模式；問題6 是關於debian系統的，咱們這裏能夠忽略）
最後# systemctl restart cobblerd.service 重起下cobbler補鞋匠服務！
三.導入centos7.3的iso鏡像
個人環境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
[root@bokeyuan ~]# cobbler import --path=/yum/ --name=centos7.3 task started: 2017-09-03_175701_import task started (id=Media import, time=Sun Sep 3 17:57:01 2017) Found a candidate signature: breed=redhat, version=rhel6 Found a candidate signature: breed=redhat, version=rhel7 Found a matching signature: breed=redhat, version=rhel7 Adding distros from path /var/www/cobbler/ks_mirror/centos7.3: creating new distro: centos7.3-x86_64 trying symlink: /var/www/cobbler/ks_mirror/centos7.3 -> /var/www/cobbler/links/centos7.3-x86_64 creating new profile: centos7.3-x86_64 associating repos checking for rsync repo(s) checking for rhn repo(s) checking for yum repo(s) starting descent into /var/www/cobbler/ks_mirror/centos7.3 for centos7.3-x86_64 processing repo at : /var/www/cobbler/ks_mirror/centos7.3 need to process repo/comps: /var/www/cobbler/ks_mirror/centos7.3 looking for /var/www/cobbler/ks_mirror/centos7.3/repodata/*comps*.xml Keeping repodata as-is :/var/www/cobbler/ks_mirror/centos7.3/repodata *** TASK COMPLETE ***
四.修改dhcp配置
# vim /etc/cobbler/dhcp.template --在此文件的第21行到第25行修改爲你對應的網段和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;
--圖形的操做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，改爲dhcp服務由cobbler來管理
242 manage_dhcp: 1 --把0改成1
# systemctl restart cobblerd.service --保存後，再重啓此服務
五.使用cobbler sync同步，並啓動xinetd服務
下面的cobbler sync 很重要，若是這步報錯必定要排出來，就經驗來講這步出錯通常是IP配置出錯，記得細心一點，個體差別不用就不詳細表述～
# cobbler sync
[root@bokeyuan ~]# cobbler sync task started: 2017-09-03_180107_sync task started (id=Sync, time=Sun Sep 3 18:01:07 2017) running pre-sync triggers cleaning trees removing: /var/www/cobbler/images/centos7.3-x86_64 removing: /var/lib/tftpboot/pxelinux.cfg/default removing: /var/lib/tftpboot/grub/images removing: /var/lib/tftpboot/grub/efidefault removing: /var/lib/tftpboot/images/centos7.3-x86_64 removing: /var/lib/tftpboot/s390x/profile_list copying bootloaders trying hardlink /usr/share/syslinux/pxelinux.0 -> /var/lib/tftpboot/pxelinux.0 trying hardlink /usr/share/syslinux/menu.c32 -> /var/lib/tftpboot/menu.c32 trying hardlink /usr/share/syslinux/memdisk -> /var/lib/tftpboot/memdisk copying distros to tftpboot copying files for distro: centos7.3-x86_64 trying hardlink /var/www/cobbler/ks_mirror/centos7.3/images/pxeboot/vmlinuz -> /var/lib/tftpboot/images/centos7.3-x86_64/vmlinuz trying hardlink /var/www/cobbler/ks_mirror/centos7.3/images/pxeboot/initrd.img -> /var/lib/tftpboot/images/centos7.3-x86_64/initrd.img copying images generating PXE configuration files generating PXE menu structure copying files for distro: centos7.3-x86_64 trying hardlink /var/www/cobbler/ks_mirror/centos7.3/images/pxeboot/vmlinuz -> /var/www/cobbler/images/centos7.3-x86_64/vmlinuz trying hardlink /var/www/cobbler/ks_mirror/centos7.3/images/pxeboot/initrd.img -> /var/www/cobbler/images/centos7.3-x86_64/initrd.img Writing template files for centos7.3-x86_64 rendering TFTPD files generating /etc/xinetd.d/tftp processing boot_files for distro: centos7.3-x86_64 cleaning link caches running post-sync triggers running python triggers from /var/lib/cobbler/triggers/sync/post/* running python trigger cobbler.modules.sync_post_restart_services running shell triggers from /var/lib/cobbler/triggers/sync/post/* running python triggers from /var/lib/cobbler/triggers/change/* running python trigger cobbler.modules.scm_track running shell triggers from /var/lib/cobbler/triggers/change/* *** TASK COMPLETE ***
# systemctl restart xinetd.service
# systemctl enable xinetd.service
六.新建另外一個虛擬機 選擇網絡安裝PXE (保證相同私有網絡,而且最好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
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
自動安裝咱們已經實現了，但如何自定義咱們想安裝的profile
重點就是你須要自定義一個ks文件
自定義ks文件的方法
1,若是你很熟悉此文件，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
--圖形的操做過程這裏省略
給你們兩個作好的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，內容以下:

# 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 : {}
我如今自定義一個ks文件，也想作成一個profile，步驟以下:
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），獲得以下的文件
# vim /var/lib/cobbler/kickstarts/centos7.3.ks --複製下面一大段信息，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/"
# System language
lang en_US
# Firewall configuration
firewall --disabled
# System authorization information
auth --useshadow --passalgo=sha512
# Use text mode install
text
firstboot --disable
# SELinux configuration

# Network information
network --bootproto=dhcp --device=eth0
# Reboot after installation
reboot
# System timezone

# System bootloader configuration
bootloader --append="rhgb quiet" --location=mbr
# Clear the Master Boot Record
zerombr
# Partition clearing information
clearpart --all --initlabel
# Disk partitioning information
part /boot --fstype="xfs" --size=300
part swap --fstype="swap" --size=2000
part / --fstype="xfs" --grow --size=1

rm /etc/yum.repos.d/* -rf
cat > /etc/yum.repos.d/local.repo << EOF

步驟二:把準備好的ks文件作成一個新的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
而後就能夠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
==================================================================
對上面操做的擴展(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聯繫，實現自動重裝系統
客戶端須要安裝koan軟件包(epel源裏就有)
# yum install koan
# koan --server=192.168.100.2 --list=profiles --192.168.100.2爲cobbler服務器IP，獲得的結果和在cobbler服務器上cobbler profile list命令獲得的結果同樣
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爲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就是重啓）
