Cobbler 概述与环境配置

• Cobbler是一个使用Python开发的开源项目，通过将部署系统所涉及的所有服务集中在一起，来提供一个全自动批量快速建立linux系统的网络安装环境。
• 使用VMware虚拟机软件演示，需连接上互联网，且虚拟机都使用NAT模式。一台CentOS7虚拟机作为服务端，另一台CentOS7虚拟机当做客户端，留作最终测试，安装系统等正常配置。客户端测试机内存需≥2G

Cobbler自动装机服务搭建步骤

• 1. 导入epel源

[root@localhost 1]# rz -E                               （直接把文件拖进来）
rz waiting to receive.
[root@localhost 1]# ls            
epel-release-latest-7.noarch.rpm                        
[root@localhost ~]# rpm -ivh epel-release-latest-7.noarch.rpm

• 2.安装Cobbler以及其相关服务软件包

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

各软件包作用如下

软件名	说明
cobbler	用来快速建立Linux网络安装环境
dhcp	用来为空白主机自动分配IP地址
tftp-server	提供引导镜像文件的下载
pykickstart	实现无人值守安装
httpd	作为控制台程序运行
rsync	实现数据同步
xinetd	提供访问控制、加强的日志和资源管理功能

• 3.修改cobbler主配置文件

[root@localhost 1]# vim /etc/cobbler/settings
next_server: 192.168.131.13       	（指向tftp服务器的IP，即本机IP）
server: 192.168.131.13				（指向cobbler服务器的IP，即本机IP）
manage_dhcp: 1                 		（让cobbler管理dhcp服务）
manage_rsync: 1					    （让cobbler管理rsync服务）
manage_tftpd: 1					    （让cobbler管理tftp服务）

• 4.启动相关服务并关闭防火墙和selinux

[root@localhost ~]# systemctl start httpd.service 
[root@localhost ~]# systemctl start cobblerd.service
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# setenforce 0

• 5.修改tftp的配置文件，并开启服务

[root@localhost ~]# vim /etc/xinetd.d/tftp 
service tftp
{disable                 = no                  （开启tftp服务，此处将yse改为no）socket_type             = dgramprotocol                = udpwait                    = yesuser                    = rootserver                  = /usr/sbin/in.tftpdserver_args             = -B 1380 -v -s /var/lib/tftpbootper_source              = 11cps                     = 100 2flags                   = IPv4
}[root@localhost ~]# systemctl restart xinetd.service
[root@localhost ~]# systemctl start rsyncd.service 

• 6.下载引导操作系统文件

[root@localhost ~]# cobbler get-loaders

*** TASK COMPLETE ***

• 7.使用盐值加密方式设置 Cobbler用户初始密码

[root@localhost ~]# openssl passwd -1 -salt '11312' '11312'   （使用盐值加密方式生成密钥。前面‘ ’里面的可以任意填写字符，后面的‘ ’里面为安装完系统后root用户的密码）
$1$5514$rQPa3RgJ5WEG3TaZT6toR1
[root@localhost ~]# vim /etc/cobbler/settings                 （将生成的密钥加入Cobbler配置文件中）
:/default_password
default_password_crypted: "$1$5514$rWPa3RgJ5XQG3IaZT6toM1"

• 8.配置 DHCP 服务

[root@localhost 1]# vim /etc/cobbler/dhcp.templatesubnet 192.168.131.0 netmask 255.255.255.0 {         （这里修改的是网段）option routers             192.168.131.13;      （修改网关）option domain-name-servers 192.168.131.2;       （修改DNS，如果网卡使用的是dhcp模式，可通过nslookup 127.0.0.1 | grepserver 查询DNS地址）option subnet-mask         255.255.255.0;range dynamic-bootp        192.168.131.10 192.168.131.100;（修改地址池）default-lease-time         21600;max-lease-time             43200;

• 9.将配置好的模板文件同步到DHCP服务的配置文件中并重启DHCP服务

[root@localhost 1]# cobbler sync
...省略...
*** TASK COMPLETE ***
[root@localhost ~]# systemctl restart dhcpd.service

• 10.导入ISO镜像文件

[root@localhost ~]# mount /dev/cdrom /mnt/
[root@localhost ~]# cobbler import --path=/mnt/ --name=CentOS-7-x86_64 --arch=x86_64
（--path:表示镜像所挂载的目录；--name：表示为安装源定义的名字；--atch：表示指定安装源的系统位数； 默认导入存放路径
为/var/www/cobbler/ks_mirror/CentOS-7-x86_64）

• 11.查看内核和初始化文件是否在在tftp-server 共享目录中

[root@localhost ~]#  yum -y install tree            （系统默认没有安装，需手动安装tree）
[root@localhost ~]# tree /var/lib/tftpboot/images   （查看文件是否存在）
/var/lib/tftpboot/images
└── CentOS-7-x86_64├── initrd.img└── vmlinuz

• 12.重启所有服务并用cobbler check 对Cobbler做检查设置

[root@localhost ~]# systemctl restart cobblerd.service 
[root@localhost ~]# systemctl restart dhcpd.service 
[root@localhost ~]# systemctl restart xinetd.service 
[root@localhost ~]# systemctl restart httpd.service 
[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:1 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:https://github.com/cobbler/cobbler/wiki/Selinux
2 : enable and start rsyncd.service with systemctl
3 : debmirror package is not installed, it will be required to manage debian deployments and repositories
4 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use themRestart cobblerd and then run 'cobbler sync' to apply changes.

• 13.所有配置完成后开启空白主机即可自动安装系统
  
  

• 此安装方式为最小化安装，安装的系统只有字符界面

• 登录账户：root 密码：11312

• 登录上后查询ip并使用Xshell进行连接操作

如需图形化界面可自行手动安装

[root@localhost ~]# yum update grub2-common
[root@localhost ~]# yum install -y fwupdate-efi
[root@localhost ~]# yum install -y net-tools
[root@localhost ~]# yum groupinstall "GNOME Desktop" "Graphical Administration Tools"
[root@localhost ~]# reboot

• 将语言修改成中文

[root@localhost ~]# vim /root/anaconda-ks.cfg  1 #version=DEVEL...略...14 lang zh_CN.UTF-8[root@localhost ~]# locale
LANG=zh_CN.UTF-8
LC_CTYPE="zh_CN.UTF-8"
