自動化工具分為三大類

預備類（Os Provisioning）
```
PXE
cobbler
```
配置管理類（Os config & Devops ）

cfengine
chef
puppet
saltstack
func
fabric
ansible

監控類（Mointor）
```
Cacti
Nagios Core
Zabbix
Zenoss core
```

網站灰度發布（依賴於前端的lb實現）

關閉Directory上一批服務器
關閉這些服務器要更新的應用
更新webapp代碼至目標主機
啟動目標應用 ，Dirtectory啟動這批服務器

發布大致流程

代碼控制（csv，svn，git）檢出要發布的代碼，發布至預發布服務器上
預發布服務器： 預發布服務器跟線上服務器環境一致，但不加入線上機器中，實施詳細的測試
自動化測試，使用webapp自動化測試工具（如thoughworks開發的selenium）可以進行完整的代碼，瀏覽器兼容性的測試
自動化灰度發布，線上批量分批次更新代碼

網站運行監控

監控數據采集，用戶行為日志，服務器性能監控，運行數據報告
監控管理 異常報警，失敗轉移，自動優雅降級

前言

運維自動化在生產環境中占據着舉足輕重的地位，尤其是面對幾百台，幾千台甚至幾萬台的服務器時，僅僅是安裝操作系統，如果不通過自動化來完成，根本是不可想象的。記得前面我們探究了基於PXE實現系統全自動安裝，但PXE同時只能提供單一操作系統的批量部署，面對生產環境中不同服務器的需求，該如何實現批量部署多版本的操作系統呢？Cobbler便可以的滿足這一實際需求，本文帶來的是基於Cobbler實現多版本操作系統批量部署。

cobbler 簡介

Cobbler是一款自動化操作系統部署的實現工具，由Python語言開發，是對PXE的二次封裝。融合多種特性，提供了CLI和Web的管理形式。同時，Cobbler也提供了API接口，方便二次開發使用。它不僅可以安裝物理機，同時也支持kvm、xen虛擬化、Guest OS的安裝。另外，它還能結合Puppet等集中化管理軟件，實現自動化管理。

組件

Cobbler的各主要組件間關系如圖所示

cobbler 服務集成

pxe 服務
DHCP
Rsync
Http
DNS
Kickstart
IPMI 電源管理

cobbler 設計方式

發行版（distro） ：表示一個操作系統，它承載了內核和initrd的信息，以及內核等其他數據
存儲庫 （repository）：保存了一個yum或者rsync存儲庫的鏡像信息
配置文件（profile）：包含了一個發行版（distro），一個kickstart文件以及可能的存儲庫（repository），還包含了更多的內核參數等其他數據
系統（system）：表示要配給的機器，它包含了一個配置文件或一個鏡像，還包含了ip和mac地址，電源管理（地址,憑據,類型）以及更為專業的數據信息
鏡像（image）：可替換一個包含不屬於此類別的文件的發行版對象（eg: 無法作為內核和initrd的對象）
以上各個組件中， 發行版，存儲庫， 配置文件為必須配置項
只有在虛擬環境中，必須要用cobbler來引導虛擬機啟動時候，才會用到系統組件
但事實上，在生產環境中需要大量的虛擬機實例的話，通常利用openstack等來實現虛擬機節點

cobbler 運行流程

dhcp
client: 從dhcp中獲取地址，訪問next_server的ip地址
next_server : 獲取啟動內核，initrd等文件
tftp: pxe引導文件，啟動cobbler選擇界面
kickstart: 確定加載項，根據nfs，http，tfp等共享獲取資源

cobbler units

```
cobbler cobbler-web 
```

配置cobbler 步驟

1 安裝cobbler，依據cobbler check檢查結果，對setting主配置文件，進行相關的修正配置
2 啟動相關的http，cobbler服務，使用cobbler sync同步設置
3 配置cobbler 所依賴的包

 * dhcp * dns * rsync * tftp

4 配置cobbler組件
針對步驟3 ，需要：
1 選定要使用的程序，選其一管理即可
2 確定是獨立管理這些服務，還有由cobbler代為管理
注意事項：
cobbler本身是不提供對應的服務程序的，因此還是需要安裝對應的程序服務的rpm包，並保證其開啟動的狀態，由cobbler管理這些服務

安裝cobbler

安裝epel源

[root@kvm ~]# yum install -y wget [root@kvm ~]# wget -O /etc/yum.repos.d/epel.repo   http://mirrors.aliyun.com/repo/epel-6.repo

設置ip轉發

[root@kvm ~]# echo 1 > /proc/sys/net/ipv4/ip_forward [root@kvm ~]# sed -i 's/net.ipv4.ip_forward = 0/net.ipv4.ip_forward = 1/' /etc/sysctl.conf [root@kvm ~]# sysctl -p

安裝cobbler

[root@kvm ~]# yum -y install cobbler dhcp httpd xinetd tftp-server syslinux pykickstart xinetd rsync cobbler-web

檢查需要安裝的配置

[root@note1 ~]# service httpd start
[root@note1 ~]# service cobblerd start
[root@note1 ~]# cobbler check

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 : change 'disable' to 'no' in /etc/xinetd.d/rsync 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 Restart cobblerd and then run 'cobbler sync' to apply changes.

解決：

vim /etc/cobbler/settings 　　next_server: 10.1.1.243 　　server: 10.1.1.243 　　manage_dhcp: 1 　　default_password_crypted: "$1$panpan52$CZn1h8wYDYvYIIMzjq7Vg/" 　　#openssl passwd -1 -salt 'panpan520' 'panwenbin'命令獲得


 cobbler get-loaders grep "disable" /etc/xinetd.d/tftp #將yes改為no 　　disable = no /etc/init.d/xinetd restart /etc/init.d/cobblerd restart

防止誤重裝系統，選項pxe_just_one

[root@note1 cobbler]# cobbler setting edit --name=pxe_just_once --value=1

配置rsync，tftp 服務由cobbler管理

默認情況下，cobbler安裝完后，會自己去管理tftp服務器，因manage_tftp
和managed_tftpd 的值默認為1
配置tftp rsync 服務，保證服務已經安裝，並且設置為開機自動啟動
需要保證xinetd服務為開機自動啟動狀態，因rsync，tftp 服務由xinetd服務統一管理

前面執行chkconfig rysnc on 和chkconfig tftp on,diable 應該就是yes了，配置文件/etc/xinetd.d/rsync

[root@note1 cobbler]# chkconfig  --level 35 xinetd on

配置dhcp服務由cobbler來管理（這里使用cobbler管理dhcp器，也可以使用dnsmasq來管理）

[root@note1 cobbler]# vim /etc/cobbler/dhcp.template #其他暫時不需要動，只修改下面的幾個內容 subnet 10.10.10.0 netmask 255.255.255.0 { option routers 10.10.10.10; option domain-name-servers      114.114.114.114 ; option subnet-mask         255.255.255.0; range dynamic-bootp        10.10.10.20 10.10.10.50; default-lease-time         21600; max-lease-time             43200; next-server                $next_server;

再次檢查

[root@localhost ~]# cobbler check The following are potential configuration items that you may want to fix: 1 : file /etc/xinetd.d/rsync does not exist 2 : debmirror package is not installed, it will be required to manage debian deployments and repositories 3 : 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.

#第一個是bug，不用管，第二個如果是Debian系統可以安裝，第三是電源fencing工具，可以不安裝
