pxe 自动化安装系统 1.需求公司机房需要reinstall os 2.pxe原理2.1 原理与概念事实上把PXE称作是一种引导方式而不是安装方式似乎更加准确， PXE(Pre-boot Execution Environment)是由Intel设计的协议， 它可以使计算机通过网络启动， 但是有一个前提条件是计算机的网卡必须具有引导功能， 这个网卡中要有一个PXE客户端。 当计算机POST自检成功以后，BIOS把网卡中ROM的PXE客户端调入内存执行， PXE客户端通过网络中的DHCP服务器获取一个IP地址， 拿到IP地址以后PXE继续引导计算机与网络中的TFTP客户端建立连接， 从而从TFTP服务器中获取开机引导文件之后请求并下载安装需要的文件。 在这个过程中需要一台服务器来提供启动文件、安装文件、 以及安装过程中的自动应答文件等 2.2 pxe工作流程图原理介绍 Client向PXE Server上的DHCP发送IP地址请求消息，DHCP检测Client是否合法（主要是检测Client的网卡MAC地址），如果合法则返回Client的IP地址，同时将启动文件pxelinux.0的位置信息一并传送给Client Client向PXE Server上的TFTP发送获取pxelinux.0请求消息，TFTP接收到消息之后再向Client发送pxelinux.0大小信息，试探Client是否满意，当TFTP收到Client发回的同意大小信息之后，正式向Client发送pxelinux.0 Client执行接收到的pxelinux.0文件 Client向TFTP Server发送针对本机的配置信息文件（在TFTP服务的pxelinux.cfg目录下，这是系统菜单文件，格式和isolinux.cfg格式一样，功能也是类似），TFTP将配置文件发回Client，继而Client根据配置文件执行后续操作。 Client向TFTP发送Linux内核请求信息，TFTP接收到消息之后将内核文件发送给Client Client向TFTP发送根文件请求信息，TFTP接收到消息之后返回Linux根文件系统 Client启动Linux内核 Client下载安装源文件，读取自动化安装脚本 3 cobbler3.1 cobbler工作流程 client裸机配置了从网络启动后，开机后会广播包请求DHCP服务器 （cobbler server）发送其分配好的一个IP DHCP服务器（cobbler server）收到请求后发送responese，包括其ip地址 client裸机拿到ip后再向cobbler server发送请求OS引导文件的请求 cobbler server告诉裸机OS引导文件的名字和TFTP server的ip和 port client裸机通过上面告知的TFTP server地址通信，下载引导文件 client裸机执行执行该引导文件，确定加载信息，选择要安装的os， 期间会再向cobbler server请求kickstart文件和os image cobbler server发送请求的kickstart和os iamge client裸机加载kickstart文件 client裸机接收os image，安装该os image 3.3 Cobbler集成的服务PXE服务支持 DHCP服务管理 DNS服务管理(可选bind,dnsmasq) 电源管理 Kickstart服务支持 YUM仓库管理 TFTP(PXE启动时需要) Apache(提供kickstart的安装源，并提供定制化的kickstart配置) 3.4 配置目录配置文件目录： /etc/cobbler /etc/cobbler/settings : cobbler 主配置文件 /etc/cobbler/iso/: iso模板配置文件 /etc/cobbler/pxe: pxe模板文件 /etc/cobbler/power: 电源配置文件 /etc/cobbler/user.conf: web服务授权配置文件 /etc/cobbler/users.digest: web访问的用户名密码配置文件 /etc/cobbler/dhcp.template : dhcp服务器的的配置末班 /etc/cobbler/dnsmasq.template : dns服务器的配置模板 /etc/cobbler/tftpd.template : tftp服务的配置模板 /etc/cobbler/modules.conf : 模块的配置文件 数据目录： /var/lib/cobbler/config/: 用于存放distros，system，profiles 等信 息配置文件 /var/lib/cobbler/triggers/: 用于存放用户定义的cobbler命令 /var/lib/cobbler/kickstart/: 默认存放kickstart文件 /var/lib/cobbler/loaders/: 存放各种引导程序 镜像目录 /var/www/cobbler/ks_mirror/: 导入的发行版系统的所有数据 /var/www/cobbler/images/ : 导入发行版的kernel和initrd镜像用于 远程网络启动 /var/www/cobbler/repo_mirror/: yum 仓库存储目录 日志目录： /var/log/cobbler/installing: 客户端安装日志 /var/log/cobbler/cobbler.log : cobbler日志 3.5 命令介绍cobbler commands介绍 cobbler check 核对当前设置是否有问题 cobbler list 列出所有的cobbler元素 cobbler report 列出元素的详细信息 cobbler sync 同步配置到数据目录,更改配置最好都要执行下 cobbler reposync 同步yum仓库 cobbler distro 查看导入的发行版系统信息 cobbler system 查看添加的系统信息 cobbler profile 查看配置信息 3.6 /etc/cobbler/settings中重要的参数设置default_password_crypted: "$1$gEc7ilpP$pg5iSOj/mlxTxEslhRvyp/" manage_dhcp：1 manage_tftpd：1 pxe_just_once：1 next_server：< tftp服务器的 IP 地址> server： 4. cobbler install4.1 系统信息[root@cobbler ~]# getenforce Disabled [root@cobbler ~]# systemctl status firewalld.service ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service;
