Cobbler自动化部署实践

Cobbler自动化部署实践

前言

Cobbler是一个自动化和简化系统安装的工具,通过使用网络引导来控制和启动安装。Cobbler的特性包括存储库镜像、Kickstart模板和连接电源管理系统。使用Cobbler之前需要先了解下PXE和Kickstart的基本原理,文章包含了Cobbler工作原理和Cobbler部署实践两部分内容,交叉关联性的内容还是蛮多的,遇到报错也不要怕,都会一步一步解决的。

使用Cobbler轻松设置和管理网络安装环境

Cobbler工作原理

Cobbler由Python语言开发,是对PXE和Kickstart以及DHCP的封装。融合很多特性,提供了CLI和Web的管理形式。更加方便的实行网络安装。同时,Cobbler也提供了API接口,使用其它语言也很容易做扩展。它不紧可以安装物理机,同时也支持kvm、xen虚拟化、Guest OS的安装。更多的是它还能结合Puppet等集中化管理软件,实现自动化的管理。

Cobbler 支持众多的发行版:Red Hat、Fedora、CentOS、Debian、Ubuntu 和 SuSE。当添加一个操作系统(通常通过使用 ISO 文件)时,Cobbler 知道如何解压缩合适的文件并调整网络服务,以正确引导机器。Cobbler 使用命令行方式管理,也提供了基于Web的图形化配置管理工具(cobbler-web)。通过配置cobbler自动部署DHCP、TFTP、HTTP,在安装过程中加载kiskstart无人值守安装应答文件实现无人值守。从客户端使用PXE引导启动安装。

Server端

第一步,启动Cobbler服务

第二步,进行Cobbler错误检查,执行cobbler check命令

第三步,进行配置同步,执行cobbler sync命令

第四步,复制相关启动文件文件到TFTP目录中

第五步,启动DHCP服务,提供地址分配

第六步,DHCP服务分配IP地址

第七步,TFTP传输启动文件

第八步,Server端接收安装信息

第九步,Server端发送ISO镜像与Kickstart文件

Client端

第一步,客户端以PXE模式启动

第二步,客户端获取IP地址

第三步,通过TFTP服务器获取启动文件

第四步,进入Cobbler安装选择界面

第五步,客户端确定加载信息

第六步,根据配置信息准备安装系统

第七步,加载Kickstart文件

第八步,传输系统安装的其它文件

第九步,进行安装系统

#清除缓存查看是否生效

#直接cobbler关联依赖包
yum install cobbler cobbler-web httpd rsync tftp-server xinetd dhcp python-ctypes debmirror pykickstart cman fence-agents dnsmasq

#使用yum-plugin-downloadonly插件
yum install -y yum-plugin-downloadonly
yum install --downloadonly --downloaddir=/tmp/cobbler cobbler cobbler-web httpd rsync tftp-server xinetd dhcp python-ctypes debmirror pykickstart cman fence-agents dnsmasq

#必要服务
1)cobbler (cobbler的核心)
2)httpd (提供cobbler的web界面)
3)dhcpd (为自动安装系统分配IP地址)
4)epel-release (为之提供yum源)
5)rsync (cobbler需要同步信息)
6)cobbler-web (cobbler的一个web插件)
7)xinetd (为rsync和tftp的守护进程)
8)tftp (传送安装的一些文件的类似ftp)

#检查cobbler配置,常见错误如下
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 : file /etc/xinetd.d/rsync does not exist
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
8 : ksvalidator was not found, install pykickstart
9 : 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
10 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

1.编辑/etc/cobbler/settings文件,找到 server选项,修改为本机IP即可
2.编辑/etc/cobbler/settings文件,找到 next_server选项,修改为本机IP即可
3.SELinux的设置, 如果上面已经关闭了SELinux就不用管了
4.执行 cobbler get-loaders,系统将自动下载loader程序,完成提示4的修复工作。
5.编辑/etc/xinetd.d/tftp文件,将文件中的disable字段的配置由yes改为no
6.编辑/etc/xinetd.d/rsync文件,将文件中的disable字段的配置由yes改为no
7.在iptables中将698025151端口打开。如果仅仅只是在内部环境中使用,建议直接将防火墙关掉
8.提示说debmirror没安装。如果不是安装 debian之类的系统,此提示可以忽略
9.修改cobbler用户的默认密码,可以使用如下命令生成密码,并使用生成后的密码替换/etc/cobbler/settings中的密码。生成密码命令:openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'其中“random-phrase-here”为任意字符
10.安装cman或者fence-agents
