已用真实服务器测试安装,只要按照步骤做就可以正常使用。


后面主要是KS文件的编写。centos7默认是xfs系统,默认的ks文件,安装包是292个,用ISO装系统,选最小化安装是297个,基本一致。

只要修改时区及分区,就可以了。

装完系统会自动进系统,不会重复,网卡如果不修改,会是ifcfg-em1



Cobbler介绍

Cobbler是一个Linux服务器安装的服务,可以通过网络启动(PXE)的方式来快速安装、重装物理服务器和虚拟机,同时还可以管理DHCP,DNS等。

Cobbler可以使用命令行方式管理,也提供了基于Web的界面管理工具(cobbler-web),还提供了API接口,可以方便二次开发使用。

Cobbler是较早前的kickstart的升级版,优点是比较容易配置,还自带web界面比较易于管理。

Cobbler内置了一个轻量级配置管理系统,但它也支持和其它配置管理系统集成,如Puppet,暂时不支持SaltStack。

1.1 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)

1.2 系统环境准备

- [root@linux-node1 ~]# cat /etc/redhat-release

- CentOS release 6.7 (Final)

- [root@linux-node1 ~]# uname -r

- 2.6.32-573.el6.x86_64

- [root@linux-node1 ~]# getenforce

- Disabled

- [root@linux-node1 ~]# /etc/init.d/iptables status

- iptables: Firewall is not running.

- [root@linux-node1 ~]# ifconfig eth0|awk -F "[ :]+" 'NR==2 {print $4}'

- 10.0.0.7

- [root@linux-node1 ~]# hostname

- linux-node1.example.com

- # 配置阿里云的epel源

- [root@linux-node1 ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

注意:

- 虚拟机网卡采用NAT模式,不要使用桥接模式,因为稍后我们会搭建DHCP服务器,在同一局域网多个DHCP服务会有冲突。

- VMware的NAT模式的dhcp服务也关闭,避免干扰。


2. Cobbler安装配置

2.1 安装Cobbler

- [root@linux-node1 ~]# yum -y install cobbler cobbler-web dhcp tftp-server pykickstart httpd

- [root@linux-node1 ~]# rpm -ql cobbler # 查看安装的文件,下面列出部分。

- /etc/cobbler # 配置文件目录

- /etc/cobbler/settings # cobbler主配置文件,这个文件是YAML格式,Cobbler是python写的程序。

- /etc/cobbler/dhcp.template # DHCP服务的配置模板

- /etc/cobbler/tftpd.template # tftp服务的配置模板

- /etc/cobbler/rsync.template # rsync服务的配置模板

- /etc/cobbler/iso # iso模板配置文件目录

- /etc/cobbler/pxe # pxe模板文件目录

- /etc/cobbler/power # 电源的配置文件目录

- /etc/cobbler/users.conf # Web服务授权配置文件

- /etc/cobbler/users.digest # 用于web访问的用户名密码配置文件

- /etc/cobbler/dnsmasq.template # DNS服务的配置模板

- /etc/cobbler/modules.conf # Cobbler模块配置文件

- /var/lib/cobbler # Cobbler数据目录

- /var/lib/cobbler/config # 配置文件

- /var/lib/cobbler/kickstarts # 默认存放kickstart文件

- /var/lib/cobbler/loaders # 存放的各种引导程序

- /var/www/cobbler # 系统安装镜像目录

- /var/www/cobbler/ks_mirror # 导入的系统镜像列表

- /var/www/cobbler/images # 导入的系统镜像启动文件

- /var/www/cobbler/repo_mirror # yum源存储目录

- /var/log/cobbler # 日志目录

- /var/log/cobbler/install.log # 客户端系统安装日志

- /var/log/cobbler/cobbler.log # cobbler日志

2.2 配置Cobbler

- [root@linux-node1 ~]# /etc/init.d/httpd restart

- 停止 httpd: [失败]

- 正在启动 httpd: [确定]

- [root@linux-node1 ~]# /etc/init.d/cobblerd start

- Starting cobbler daemon: [确定]

- [root@linux-node1 ~]# cobbler check # 检查Cobbler的配置,如果看不到下面的结果,再次执行/etc/init.d/cobblerd restart

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

- 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 : 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.

- 4 : change 'disable' to 'no' in /etc/xinetd.d/rsync

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

- 6 : 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

- 7 : 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.


- # 看着上面的结果,一个一个解决。

- # 第1、2、6个问题,顺便修改其他功能

- [root@linux-node1 ~]# cp /etc/cobbler/settings{,.ori} # 备份

- # server,Cobbler服务器的IP。

- sed -i 's/server: 127.0.0.1/server: 10.0.0.7/' /etc/cobbler/settings

- # next_server,如果用Cobbler管理DHCP,修改本项,作用不解释,看kickstart。

- sed -i 's/next_server: 127.0.0.1/next_server: 10.0.0.7/' /etc/cobbler/settings

- # 用Cobbler管理DHCP

- sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings

- # 防止循环装系统,适用于服务器第一启动项是PXE启动。

- sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings

- # 设置新装系统的默认root密码123456。下面的命令来源于提示6。random-phrase-here为干扰码,可以自行设定。

- [root@linux-node1 ~]# openssl passwd -1 -salt 'root' '123456'

- $1$root$j0bp.KLPyr.u9kgQ428D10

- [root@linux-node1 ~]# vim /etc/cobbler/settings

- default_password_crypted: "$1$root$j0bp.KLPyr.u9kgQ428D10"

- # 第3个问题

- [root@linux-node1 ~]# cobbler get-loaders # 会自动从官网下载

- [root@linux-node1 ~]# cd /var/lib/cobbler/loaders/ # 下载的内容

- [root@linux-node1 loaders]# ls

- COPYING.elilo COPYING.yaboot grub-x86_64.efi menu.c32 README

- COPYING.syslinux elilo-ia64.efi grub-x86.efi pxelinux.0 yaboot

- # 第4个问题

- [root@linux-node1 ~]# vim /etc/xinetd.d/rsync

- disable = no

- [root@linux-node1 ~]# /etc/init.d/xinetd restart

- 停止 xinetd: [确定]

- 正在启动 xinetd: [确定]

- [root@linux-node1 ~]# /etc/init.d/cobblerd restart

- Stopping cobbler daemon: [确定]

- Starting cobbler daemon: [确定]

- [root@linux-node1 ~]# 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 # 和debian系统相关,不需要

- 2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them # fence设备相关,不需要

- Restart cobblerd and then run 'cobbler sync' to apply changes.


2.3 配置DHCP

- # 修改cobbler的dhcp模版,不要直接修改dhcp本身的配置文件,因为cobbler会覆盖。

- [root@linux-node1 ~]# vim /etc/cobbler/dhcp.template

- # 仅列出修改过的字段

subnet 10.0.0.0 netmask 255.255.255.0 {

option routers 10.0.0.2;

option domain-name-servers 10.0.0.2;

option subnet-mask 255.255.255.0;

range dynamic-bootp 10.0.0.100 10.0.0.200;

3.4 安装系统

可以很愉快的告诉你到这里就可以安装系统了!

新建一台虚拟机,不解释,开机就可以看到下面的图片了!

有没有发现不美观的地方?

spacer.gifwKiom1ctOsaChp1_AAAoHKpkwbQ335.png

网址不是我的!改!

- #修改Cobbler提示

- [root@linux-node1 ~]# vim /etc/cobbler/pxe/pxedefault.template

- MENU TITLE Cobbler | http://www.zyops.com

- [root@linux-node1 ~]# cobbler sync # 修改配置都要同步

OK,现在好看多了。选择第二项就可以继续装机了。你可以让系统飞着,然后接着看下文!!

5. 定制化安装

可能从学习kickstart开始就有人想怎样能够指定某台服务器使用指定ks文件,kickstart实现这功能可能比较复杂,但是Cobbler就很简单了。

spacer.gif

区分一台服务器的最简单的方法就是物理MAC地址。

物理服务器的MAC地址在服务器上的标签上写了。
