COBBLER无人值守安装

说在最前面的话 
在看Cobbler之前请大家先看一下Kickstart无人值守安装，了解一下Cobbler的实现原理。但是Cobbler是独立的，不需要先安装Kickstart然后再安装Cobbler，这是写给不了解Kickstart的人看的。

1. 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

  1. [[email protected] ~]# cat /etc/redhat-release
  2. CentOS release 6.7 (Final)
  3. [[email protected] ~]# uname -r
  4. 2.6.32-573.el6.x86_64
  5. [[email protected] ~]# getenforce
  6. Disabled
  7. [[email protected] ~]# /etc/init.d/iptables status
  8. iptables: Firewall is not running.
  9. [[email protected] ~]# ifconfig eth0|awk -F "[ :]+" ‘NR==2 {print $4}‘
  10. 10.0.0.7
  11. [[email protected] ~]# hostname
  12. linux-node1.example.com
  13. # 配置阿里云的epel源
  14. [[email protected] ~]# 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

  1. [[email protected] ~]# yum -y install cobbler cobbler-web dhcp tftp-server pykickstart httpd
  2. [[email protected] ~]# rpm -ql cobbler # 查看安装的文件，下面列出部分。
  3. /etc/cobbler # 配置文件目录
  4. /etc/cobbler/settings # cobbler主配置文件，这个文件是YAML格式，Cobbler是python写的程序。
  5. /etc/cobbler/dhcp.template # DHCP服务的配置模板
  6. /etc/cobbler/tftpd.template # tftp服务的配置模板
  7. /etc/cobbler/rsync.template # rsync服务的配置模板
  8. /etc/cobbler/iso # iso模板配置文件目录
  9. /etc/cobbler/pxe # pxe模板文件目录
  10. /etc/cobbler/power # 电源的配置文件目录
  11. /etc/cobbler/users.conf # Web服务授权配置文件
  12. /etc/cobbler/users.digest # 用于web访问的用户名密码配置文件
  13. /etc/cobbler/dnsmasq.template # DNS服务的配置模板
  14. /etc/cobbler/modules.conf # Cobbler模块配置文件

  17. /var/lib/cobbler/config # 配置文件
  18. /var/lib/cobbler/kickstarts # 默认存放kickstart文件
  19. /var/lib/cobbler/loaders # 存放的各种引导程序
  21. /var/www/cobbler # 系统安装镜像目录
  22. /var/www/cobbler/ks_mirror # 导入的系统镜像列表
  23. /var/www/cobbler/images # 导入的系统镜像启动文件
  24. /var/www/cobbler/repo_mirror # yum源存储目录
  26. /var/log/cobbler # 日志目录
  27. /var/log/cobbler/install.log # 客户端系统安装日志
  28. /var/log/cobbler/cobbler.log # cobbler日志

2.2 配置Cobbler

  1. [[email protected] ~]# /etc/init.d/httpd restart
  2. 停止 httpd： [失败]
  3. 正在启动 httpd： [确定]
  4. [[email protected] ~]# /etc/init.d/cobblerd start
  5. Starting cobbler daemon: [确定]
  6. [[email protected] ~]# 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
  7. The following are potential configuration items that you may want to fix:
  9. 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.
  10. 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.
  11. 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.
  12. 4 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/rsync
  13. 5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
  14. 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
  15. 7 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
  17. Restart cobblerd and then run ‘cobbler sync‘ to apply changes.
  19. # 看着上面的结果，一个一个解决。
  20. # 第1、2、6个问题，顺便修改其他功能
  21. [[email protected] ~]# cp /etc/cobbler/settings{,.ori} # 备份
  23. # server，Cobbler服务器的IP。
  24. sed -i ‘s/server: 127.0.0.1/server: 10.0.0.7/‘ /etc/cobbler/settings
  26. # next_server，如果用Cobbler管理DHCP，修改本项，作用不解释，看kickstart。
  27. sed -i ‘s/next_server: 127.0.0.1/next_server: 10.0.0.7/‘ /etc/cobbler/settings
  29. # 用Cobbler管理DHCP
  30. sed -i ‘s/manage_dhcp: 0/manage_dhcp: 1/‘ /etc/cobbler/settings
  32. # 防止循环装系统，适用于服务器第一启动项是PXE启动。
  33. sed -i ‘s/pxe_just_once: 0/pxe_just_once: 1/‘ /etc/cobbler/settings
  35. # 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。
  36. [[email protected] ~]# openssl passwd -1 -salt ‘oldboy‘ ‘123456‘
  37. $1$oldboy$Npg9Pt9k98Mlg0ZeqHAuN1
  38. [[email protected] ~]# vim /etc/cobbler/settings
  39. default_password_crypted: "$1$oldboy$Npg9Pt9k98Mlg0ZeqHAuN1"
  41. # 第3个问题
  42. [[email protected] ~]# cobbler get-loaders # 会自动从官网下载

  59. The following are potential configuration items that you may want to fix:
  61. 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
  62. 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
  63. Restart cobblerd and then run ‘cobbler sync‘ to apply changes.

2.3 配置DHCP

网址不是我的！改！

  1. #修改Cobbler提示
  2. [[email protected] ~]# vim /etc/cobbler/pxe/pxedefault.template
  3. MENU TITLE Cobbler | http://www.zyops.com
  4. [[email protected] ~]# 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！！

4. ks.cfg文件简析

文件大部分参数含义见kickstart文章，此处只讲一些不同的地方。同时可以参考模板文件。

  1. [[email protected] kickstarts]# cat CentOS-7.1-x86_64.cfg
  2. # Cobbler for Kickstart Configurator for CentOS 7.1 by yao zhang
  3. install
  4. url --url=$tree # 这些$开头的变量都是调用配置文件里的值。
  5. text
  6. lang en_US.UTF-8
  7. keyboard us
  8. zerombr
  9. bootloader --location=mbr --driveorder=sda --append="crashkernel=auto rhgb quiet"
  10. # Network information

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。

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。

虚拟机的MAC查看

  1. cobbler system add --name=oldboy --mac=00：0C：29：7F：2F：A1 --profile=CentOS-7.1-x86_64 --ip-address=10.0.0.111 --subnet=255.255.255.0 --gateway=10.0.0.2 --interface=eth0 --static=1 --hostname=oldboy.example.com --name-servers="114.114.114.114 8.8.8.8"
  2. # --name 自定义，但不能重复
  3. # 查看定义的列表
  4. [[email protected] ~]# cobbler system list
  5. oldboy
  6. [[email protected] ~]# cobbler sync

再次开机安装就不再询问选择了，直接安装。

6. Cobbler的Web管理界面的安装与配置

已经安装cobbler-web软件。

访问网址：http://10.0.0.7/cobbler_web和https://10.0.0.7/cobbler_web

默认用户名：cobbler 
默认密码 ：cobbler

  1. /etc/cobbler/users.conf # Web服务授权配置文件
  2. /etc/cobbler/users.digest # 用于web访问的用户名密码配置文件
  3. [[email protected] ~]# cat /etc/cobbler/users.digest
  4. cobbler:Cobbler:a2d6bae81669d707b72c0bd9806e01f3
  5. # 设置Cobbler web用户登陆密码
  6. # 在Cobbler组添加cobbler用户，提示输入2遍密码确认
  7. [[email protected] ~]# htdigest /etc/cobbler/users.digest "Cobbler" cobbler
  8. Changing password for user cobbler in realm Cobbler
  9. New password: 123456
  10. Re-type new password:123456
  11. [[email protected] ~]# cobbler sync
  12. [[email protected] ~]# /etc/init.d/httpd restart
  13. 停止 httpd： [确定]
  14. 正在启动 httpd： [确定]
  15. [[email protected] ~]# /etc/init.d/cobblerd restart
  16. Stopping cobbler daemon: [确定]
  17. Starting cobbler daemon: [确定]

以后就需要用123456这个密码登录了。

接下来的操作就是点点鼠标了。
