Cobbler自动安装RHEL7.3

1.实验环境

cobbler服务器: CentOS7.0 64位

IP地址: 192.168.126.120?

子网掩码: 255.255.255.0

2.Cobbler安装配置

2.1 安装CentOS7(略)

2.2 关闭SELinux

[[email protected] ~]# vim /etc/selinux/config

SELINUX=disabled

或者

[[email protected] ~]# sed -i ‘s/SELINUX=.*/SELINUX=disabled/g‘ /etc/selinux/config

修改SELinux配置文件后需要重启才能生效

[[email protected] ~]# reboot

2.3关闭防火墙

[[email protected] ~]# systemctl stop firewalld.service

[[email protected] ~]# systemctl disable firewalld.service

rm ‘/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service‘

rm ‘/etc/systemd/system/basic.target.wants/firewalld.service‘

2.4安装EPEL

下载并安装EPEL包

[[email protected] ~]# wget http://mirrors.ustc.edu.cn/fedora/epel//7/x86_64/e/epel-release-7-9.noarch.rpm

[[email protected] ~]# yum -y localinstall epel-release-7-9.noarch.rpm

安装完成后检查EPEL是否已添加到源列表

[[email protected] ~]# yum repolist

2.5安装cobbler/dhcp/xinetd/tcpdump/pykickstart

[[email protected] ~]# yum -y install cobbler-web

[[email protected] ~]# yum -y install dhcp

[[email protected] ~]# yum -y install xinetd

[[email protected] ~]# yum -y install tcpdump

[[email protected] ~]# yum -y install pykickstart

2.6 配置cobbler

启用cobbler及http服务

[[email protected] ~]# systemctl enable cobblerd.service

ln -s ‘/usr/lib/systemd/system/cobblerd.service‘ ‘/etc/systemd/system/multi-user.target.wants/cobblerd.service‘

[[email protected] ~]# systemctl start cobblerd.service

[[email protected] ~]# systemctl enable httpd.service

ln -s ‘/usr/lib/systemd/system/httpd.service‘ ‘/etc/systemd/system/multi-user.target.wants/httpd.service‘

[[email protected] ~]# systemctl start httpd.service

配置cobbler

生成密码：

[[email protected] ~]# openssl passwd -1 -salt "cobbler" "123456"

$1$cobbler$sqDDOBeLKJVmxTCZr52/11

密码是123456，此密码就是Linux安装完成后的root密码

修改cobbler配置：

[[email protected] ~]# vim /etc/cobbler/settings //打开配置文件，修改3处地方

server: 192.168.126.120 //把127.0.0.1改为本机的IP地址

next_server: 192.168.126.120 //把127.0.0.1改为本机的IP地址

default_password_crypted: "$1$cobbler$sqDDOBeLKJVmxTCZr52/11" //把原来的加密密码改为上面生成的密码

配置tftp

[[email protected] ~]# ?vim /etc/xinetd.d/tftp

disable = no //找到disable那行把yes改成no

[[email protected] ~]# systemctl enable xinetd.service

[[email protected] ~]# systemctl start xinetd.service

[[email protected] ~]# systemctl enable tftp.service

[[email protected] ~]# systemctl start tftp.service

*** TASK COMPLETE ***

启用rsync

[[email protected] ~]# systemctl enable rsyncd.service

ln -s ‘/usr/lib/systemd/system/rsyncd.service‘ ‘/etc/systemd/system/multi-user.target.wants/rsyncd.service‘

[[email protected] ~]# systemctl start rsyncd.service

Cobbler check

[[email protected] ~]# systemctl restart cobblerd.service

[[email protected] ~]# cobbler check

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

?

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

2 : 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.

以上警告可忽略

2.8配置dhcp

首先修改cobbler配置，让cobbler来管理dhcp服务

[[email protected] ~]# vim /etc/cobbler/settings

manage_dhcp: 1

接下来修改/etc/cobbler/dhcp.template，此文件是cobbler管理dhcp的模板

对于此文件，只需要修改如下部分:

subnet 192.168.126.0 netmask 255.255.255.0 {

     option routers             192.168.126.1;

     option domain-name-servers 192.168.126.10;

     option subnet-mask         255.255.255.0;

     range dynamic-bootp        192.168.126.150 192.168.126.250;

     default-lease-time         21600;

     max-lease-time             43200;

     next-server                $next_server;

同步cobbler

[[email protected] ~]# cobbler sync

2.9修改profile

在/var/lib/cobbler/kickstarts目录下创建kickstart profie文件

cobbler自动安装系统

一.cobbler工作流程 远程裸机开机启动网络启动,开机后会广播给DHCP服务器,分配给远程主机一个IP地址 拿到IP地址后,远程主机向cobbler server发送请求OS启动文件的请求. cobbler服务器告诉远程主机OS应到文件的名字,和 TFTP 服务器的IP地址和端口. 远程主机根据IP地址和端口,到TFTP 服务器上下载引导文件. 远程主机执行OS引导文件,加载信息和menu.c32,启动选择菜单,选择要安装的OS,然后向cobbler服务器请求 kickstart 文件和OS
