1.Cobbler介绍
由于其设计要管理的各种各样的技术，Cobbler可能是一个稍微复杂的系统，但它在安装后立即支持大量功能，几乎不需要任何定制。在开始使用Cobbler之前，您应该对PXE具有良好的工作知识以及您选择的配送的自动化安装方法
Cobbler官方文档：http://cobbler.github.io/manuals/quickstart/
1.1 系统环境准备
[root@linux-node1 ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[root@linux-node1 ~]# uname -r
3.10.0-327.el7.x86_64
[root@linux-node1 ~]# getenforce
Disabled
[root@linux-node1 ~]# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
[root@linux-node1 ~]# ifconfig eth0|awk -F "[ :]+" 'NR==2 {print $3}'
192.168.56.32
[root@linux-node1 ~]# hostname
linux-node1.example.com
[root@linux-node1 ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.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。
1.2 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)
2. Cobbler安装配置
2.1 安装Cobbler
[root@linux-node1 ~]# yum -y install cobbler cobbler-web dhcp xinetd 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 ~]# systemctl restart httpd.service
[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systemctl restart cobblerd.service
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 : change 'disable' to 'no' in /etc/xinetd.d/tftp
4 : 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.
5 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
7 : 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
8 : 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。
[root@linux-node1 ~]# sed -i 's/server: 127.0.0.1/server: 192.168.56.32/' /etc/cobbler/settings
# next_server，如果用Cobbler管理DHCP，修改本项
[root@linux-node1 ~]# sed -i 's/next_server: 127.0.0.1/next_server: 192.168.56.32/' /etc/cobbler/settings
# 用Cobbler管理DHCP
[root@linux-node1 ~]# 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。
[root@linux-node1 ~]# 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
openssl passwd -1 -salt 'Jhon' '123456'
[root@linux-node1 ~]# vim /etc/cobbler/settings
default_password_crypted: "$1$Jhon$.IpC0Qc6iUS7IBSy7zP7U1"
#第3个问题
[root@linux-node1 ~]# cat -n /etc/xinetd.d/tftp
[root@linux-node1 ~]# sed -i '14s#yes#no#' /etc/xinetd.d/tftp
#第4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.syslinux COPYING.yaboot elilo-ia64.efi grub-x86_64.efi grub-x86.efi menu.c32 pxelinux.0 README yaboot
#第5个问题
[root@linux-node1 loaders]# systemctl enable rsyncd.service
[root@linux-node1 loaders]# systemctl start rsyncd.service
#重启cobbler
[root@linux-node1 loaders]# systemctl restart cobblerd.service
[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 192.168.56.0 netmask 255.255.255.0 {

3.4 安装系统
新建一台虚拟机，开机就可以看到下面的图片了！
修改http网址：
#修改Cobbler提示 [root@linux-node1 ~]# vim /etc/cobbler/pxe/pxedefault.template MENU TITLE Cobbler | http://xionghaier.centoscn.cn/ [root@linux-node1 ~]# cobbler sync # 修改配置都要同步
3.5同步官方镜像源
cobbler repo --name=CentOS7_x86_64-epel --mirror=https://mirrors.aliyun.com/epel/7Server/x86_64/Packages/ --arch=x86_64 --breed=yum
#完成后执行如下命令
cobbler reposync4. 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
~]# cobbler system add --name=CentOS64 --mac-address=00:50:56:24:66:A2 --profile=CentOS-7.2-x86_64 --ip-address=118.190.201.20 --subnet=255.255.255.0 --gateway=118.190.201.2 --interface=eth0 --static=1 --hostname=linux.example.com --name-servers="118.190.201.2" --kickstart=/var/lib/cobbler/kickstarts/CentOS-7.2-x86_64.cfg# --name 自定义，但不能重复 # 查看定义的列表 [root@linux-node1 kickstarts]# cobbler system list John [root@linux-node1 kickstarts]# cobbler sync
再次开机安装就不再询问选择了，直接安装。
然而，出现了如下的报错信息
解决办法如下：
cobbler profile report --name=CentOS-7.1-x86_64 Name : CentOS-7.1-x86_64 TFTP Boot Files : {} Comment : DHCP Tag : default Distribution : CentOS-7.1-x86_64 Enable gPXE? : True Enable PXE Menu? : 1 [...]
So let’s modify the profile to disable gPXE support:
cobbler profile edit --name=CentOS-7.2-x86_64 --enable-gpxe=False cobbler sync
Verify that the change was made:
cobbler profile report --name=CentOS-7.2-x86_64 [...] Enable gPXE? : False [...]
此为解决方法参考文档：https://funcptr.net/2015/07/08/cobbler-with-centos-7-failure-to-boot/kickstart/
https://www.centos.org/forums/viewtopic.php?t=55650
解决办法：
vim /etc/cobbler/settings # 修改settings中参数，由cobbler控制dhcp
manage_dhcp: 1 ##仅作参考
重新编写ks.cfg文件
[root@node01 kickstarts]# cat Centos7.2-x86_64.cfg #platform=x86, AMD64, or Intel EM64T #version=DEVEL # Install OS instead of upgrade install # Keyboard layouts keyboard 'us' # Root password #rootpw --iscrypted $1$m1pE0DG6$vALBphGGynqvUzfJaWZ6U1 rootpw --iscrypted $default_password_crypted # Use network installation url --url="$tree" # System language lang en_US # Firewall configuration firewall --disabled # System authorization information auth --useshadow --passalgo=sha512 # Use graphical install graphical firstboot --disable # SELinux configuration selinux --disabled # Network information network --bootproto=dhcp --device=eth0 network --bootproto=dhcp --device=eth1 # Reboot after installation reboot # System timezone timezone Asia/Shanghai # System bootloader configuration bootloader --location=mbr # Clear the Master Boot Record zerombr # Partition clearing information clearpart --all --initlabel # Disk partitioning information part /boot --asprimary --fstype="ext4" --size=200 part swap --fstype="swap" --size=1024 part / --fstype="ext4" --grow --size=1 %packages @base #@core @compat-libraries @debugging @development #@gnome-desktop #@X Window System %end
可以参考另一篇文章ks.cfg文件：https://www.xionghaier.cn/?p=74
命令补充
