Cobbler自动装机服务搭建步骤 1. 导入epel源
[rootlocalhost 1]# rz -E 直接把文件拖进来
rz waiting to receive.
[rootlocalhost 1]# ls
epel-release-latest-7.noarch.rpm
[rootlocalhost ~]# rpm -ivh epel-release-latest-7.noarch.rpm2.安装Cobbler以及其相关服务软件包
[rootlocalhost ~]# 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
[rootlocalhost 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
[rootlocalhost ~]# systemctl start httpd.service
[rootlocalhost ~]# systemctl start cobblerd.service
[rootlocalhost ~]# systemctl stop firewalld
[rootlocalhost ~]# setenforce 05.修改tftp的配置文件并开启服务
[rootlocalhost ~]# vim /etc/xinetd.d/tftp
service tftp
{disable no 开启tftp服务此处将yse改为nosocket_type dgramprotocol udpwait yesuser rootserver /usr/sbin/in.tftpdserver_args -B 1380 -v -s /var/lib/tftpbootper_source 11cps 100 2flags IPv4
}[rootlocalhost ~]# systemctl restart xinetd.service
[rootlocalhost ~]# systemctl start rsyncd.service 6.下载引导操作系统文件
[rootlocalhost ~]# cobbler get-loaders

*** TASK COMPLETE *** 7.使用盐值加密方式设置 Cobbler用户初始密码
[rootlocalhost ~]# 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
[rootlocalhost ~]# 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
[rootlocalhost 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
[rootlocalhost 1]# cobbler sync
...省略...
*** TASK COMPLETE ***
[rootlocalhost ~]# systemctl restart dhcpd.service10.导入ISO镜像文件
[rootlocalhost ~]# mount /dev/cdrom /mnt/
[rootlocalhost ~]# cobbler import --path/mnt/ --nameCentOS-7-x86_64 --archx86_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_6411.查看内核和初始化文件是否在在tftp-server 共享目录中
[rootlocalhost ~]# yum -y install tree 系统默认没有安装需手动安装tree
[rootlocalhost ~]# 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
[rootlocalhost ~]# systemctl restart cobblerd.service
[rootlocalhost ~]# systemctl restart dhcpd.service
[rootlocalhost ~]# systemctl restart xinetd.service
[rootlocalhost ~]# systemctl restart httpd.service
[rootlocalhost ~]# 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
[rootlocalhost ~]# yum update grub2-common
[rootlocalhost ~]# yum install -y fwupdate-efi
[rootlocalhost ~]# yum install -y net-tools
[rootlocalhost ~]# yum groupinstall GNOME Desktop Graphical Administration Tools
[rootlocalhost ~]# reboot将语言修改成中文
