网站灰度发布（依赖于前端的lb实现）

关闭Directory上一批服务器

关闭这些服务器要更新的应用

更新webapp代码至目标主机

启动目标应用 ，Dirtectory启动这批服务器

发布大致流程

代码控制（csv，svn，git）检出要发布的代码，发布至预发布服务器上

预发布服务器： 预发布服务器跟线上服务器环境一致，但不加入线上机器中，实施详细的测试

自动化测试，使用webapp自动化测试工具（如thoughworks开发的selenium）可以进行完整的代码，浏览器兼容性的测试

自动化灰度发布，线上批量分批次更新代码

网站运行监控

监控数据采集，用户行为日志，服务器性能监控，运行数据报告

监控管理 异常报警，失败转移，自动优雅降级

前言

运维自动化在生产环境中占据着举足轻重的地位，尤其是面对几百台，几千台甚至几万台的服务器时，仅仅是安装操作系统，如果不通过自动化来完成，根本是不可想象的。记得前面我们探究了基于PXE实现系统全自动安装，但PXE同时只能提供单一操作系统的批量部署，面对生产环境中不同服务器的需求，该如何实现批量部署多版本的操作系统呢？Cobbler便可以的满足这一实际需求，本文带来的是基于Cobbler实现多版本操作系统批量部署。

cobbler 简介

Cobbler是一款自动化操作系统部署的实现工具，由Python语言开发，是对PXE的二次封装。融合多种特性，提供了CLI和Web的管理形式。同时，Cobbler也提供了API接口，方便二次开发使用。它不仅可以安装物理机，同时也支持kvm、xen虚拟化、Guest OS的安装。另外，它还能结合Puppet等集中化管理软件，实现自动化管理。

组件

Cobbler的各主要组件间关系如图所示

cobbler 服务集成

pxe 服务

DHCP

Rsync

Http

DNS

Kickstart

IPMI 电源管理

cobbler 设计方式

发行版（distro） ：表示一个操作系统，它承载了内核和initrd的信息，以及内核等其他数据

存储库 （repository）：保存了一个yum或者rsync存储库的镜像信息

配置文件（profile）：包含了一个发行版（distro），一个kickstart文件以及可能的存储库（repository），还包含了更多的内核参数等其他数据

系统（system）：表示要配给的机器，它包含了一个配置文件或一个镜像，还包含了ip和mac地址，电源管理（地址,凭据,类型）以及更为专业的数据信息

镜像（image）：可替换一个包含不属于此类别的文件的发行版对象（eg: 无法作为内核和initrd的对象）

以上各个组件中， 发行版，存储库， 配置文件为必须配置项

只有在虚拟环境中，必须要用cobbler来引导虚拟机启动时候，才会用到系统组件

但事实上，在生产环境中需要大量的虚拟机实例的话，通常利用openstack等来实现虚拟机节点

cobbler 运行流程

dhcp

client: 从dhcp中获取地址，访问next_server的ip地址

next_server : 获取启动内核，initrd等文件

tftp: pxe引导文件，启动cobbler选择界面

kickstart: 确定加载项，根据nfs，http，tfp等共享获取资源

cobbler units

cobbler

cobbler-web 
```

配置cobbler 步骤

1 安装cobbler，依据cobbler check检查结果，对setting主配置文件，进行相关的修正配置
2 启动相关的http，cobbler服务，使用cobbler sync同步设置
3 配置cobbler 所依赖的包

     * dhcp

     * dns

     * rsync

     * tftp

4 配置cobbler组件
针对步骤3 ，需要：
1 选定要使用的程序，选其一管理即可
2 确定是独立管理这些服务，还有由cobbler代为管理
注意事项：
cobbler本身是不提供对应的服务程序的，因此还是需要安装对应的程序服务的rpm包，并保证其开启动的状态，由cobbler管理这些服务

安装cobbler

安装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

[root@kvm ~]# echo  > /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

安装cobbler

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

检查需要安装的配置

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

 : 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.

 : 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.

 : change 'disable' to 'no' in /etc/xinetd.d/tftp

 : 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., menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.

 : change 'disable' to 'no' in /etc/xinetd.d/rsync

 : debmirror package is not installed, it will be required to manage debian deployments and repositories

 : 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.

解决：

vim /etc/cobbler/settings

　　next_server: 10.1.1.243

　　server: 10.1.1.243

　　manage_dhcp:

　　default_password_crypted: "$1$panpan52$CZn1h8wYDYvYIIMzjq7Vg/"

　　#openssl passwd - -salt 'panpan520' 'panwenbin'命令获得


cobbler get-loaders

grep "disable" /etc/xinetd.d/tftp #将yes改为no

　　disable = no

/etc/init.d/xinetd restart

/etc/init.d/cobblerd restart

防止误重装系统，选项pxe_just_one

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

配置rsync，tftp 服务由cobbler管理

默认情况下，cobbler安装完后，会自己去管理tftp服务器，因manage_tftp
和managed_tftpd 的值默认为1
配置tftp rsync 服务，保证服务已经安装，并且设置为开机自动启动
需要保证xinetd服务为开机自动启动状态，因rsync，tftp 服务由xinetd服务统一管理

前面执行chkconfig rysnc on 和chkconfig tftp on,diable 应该就是yes了，配置文件/etc/xinetd.d/rsync

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

配置dhcp服务由cobbler来管理（这里使用cobbler管理dhcp器，也可以使用dnsmasq来管理）

[root@note1 cobbler]# vim /etc/cobbler/dhcp.template

#其他暂时不需要动，只修改下面的几个内容

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         ;

     max-lease-time             ;

     next-server                $next_server;

[root@localhost ~]# cobbler check

The following are potential configuration items that you may want to fix:

 : file /etc/xinetd.d/rsync does not exist

 : debmirror package is not installed, it will be required to manage debian deployments and repositories

 : 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.

#第一个是bug，不用管，第二个如果是Debian系统可以安装，第三是电源fencing工具，可以不安装

配置绑定mac地址和IP地址 ,开机自动选择

[root@note1 kickstarts]# cobbler system add --name=budongshu --mac=:0C:::1D: --profile=Centos--x86_64  \

--ip-address=10.10.10.23 --subnet=255.255.255.0 --gateway=10.10.10.10 --interface=eth0 \

--static= --hostname=budongshu --name-servers="114.114.114.114 8.8.8.8"

[authentication]

module = authn_pam
