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。
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)

[root@linux-node2 ~]# systemctl start cobblerd
[root@linux-node2 ~]# cobbler check #通过该命令可以查看cobbler的服务是否正常，需要解决哪些问题
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。

6、使用koan重装系统
在新安装的系统中安装koan
[root@localhost ~]# yum install -y epel-release
[root@localhost ~]# yum install -y koan
[root@localhost ~]# koan --server=192.168.56.12 --list=profiles #查看可使用的安装包
- looking for Cobbler at http://192.168.56.12:80/cobbler_api

- ['/sbin/grubby', '--update-kernel', '/boot/vmlinuz_koan', '--remove-args=root']
- reboot to apply changes
[root@localhost ~]# reboot #重启自动安装
#那么koan是怎么实现重装的呢？koan会在grub增加一个启动项，从告诉系统从该启动项进行启动
[root@localhost grub2]# cat grub.cfg |grep "linux16"
linux16 /vmlinuz_koan ro crashkernel=auto rhgb quiet LANG=en_US.UTF-8 ks=http://192.168.56.12/cblr/svc/op/ks/profile/Centos-7.4-x86_64 ksdevice=link kssendmac lang= text

到此就能实现自动重装了！
7、Cobbler的图形界面
cobbler的图形界面需要安装cobbler_web，前面已经安装，启动httpd后，直接访问：https://192.168.56.12/cobbler_web，默认的用户名密码是cobbler，cobbler
在图形界面可以对导入镜像，kickstarts文件的修改与配置等操作。
[root@linux-node2 ~]# cat /etc/cobbler/users.digest #cobbler的密码存放位置
cobbler:Cobbler:a2d6bae81669d707b72c0bd9806e01f3
[root@linux-node2 ~]# htdigest /etc/cobbler/users.digest "Cobbler" cobbler #修改cobbler界面的密码
Changing password for user cobbler in realm Cobbler
New password: 123123
Re-type new password: 123123
[root@linux-node2 ~]# cat /etc/cobbler/users.digest
cobbler:Cobbler:37af732f18fe2c533372649699188af3
8、Cobbler的基本组件
Disribution : 发行内核，initrd等东西
Repository: 创建仓库，比如yum仓库等。
system： 通过mac地址来定制化系统
profile： 对需要安装某个系统的所有配置。9、创建yum仓库
cobbler不但可以装机，还可以自建yum仓库，这个仓库可以从公网的yum源进行同步到公司内网，节省带宽。同步命令如下所示：
#添加阿里云的epel源
cobbler repo add --name=Centos-7.x86-64-epel --mirror=https://mirrors.aliyun.com/epel/7Server/x86_64/ --arch=x86_64 --breed=yum
#添加阿里云的openstack-newton源
cobbler repo add --name=openstack-newton --mirror=https://mirrors.aliyun.com/centos/7.4.1708/cloud/x86_64/openstack-newton/ --arch=x86_64 --breed=yum
cobbler reposync --tries=3 --no-fail
#参数解释：
repo add : 添加一个repo源
name ： 为这个yum源命名
mirror ： 指定一个源的地址。
arch ： 指定平台
breed： 类型为yum
#演示：
[root@linux-node2 opt]# cobbler repo add --name=openstack-newton --mirror=https://mirrors.aliyun.com/centos/7.4.1708/cloud/x86_64/openstack-newton/ --arch=x86_64 --breed=yum #添加openstack-newton源
[root@linux-node2 opt]# cobbler profile edit --name=Centos-7.4-x86_64 --repos=openstack-newton #关联repos仓库
[root@linux-node2 opt]# cobbler profile report

以上的操作也可以在cobbler界面上，把yum源添加到Centos-7.4-x86_64的profile中。如图： 
10、Cobbler定制安装
（1）生成mac地址
（2）定制系统
[root@linux-node2 ~]# cobbler system add --name=linux-node4 --mac=00:50:56:33:F1:45 \
> --profile=Centos-7.3-x86_64 \
> --ip-address=192.168.56.110 --subnet=255.255.255.0 \
> --gateway=192.168.56.2 --interface=eth0 \
> --static=1 --hostname=linux-node4.example.com \
> --name-servers="192.168.56.2" \
> --kickstart=/var/lib/cobbler/kickstarts/Centos-7.3-x86_64.cfg
[root@linux-node2 ~]# cobbler system list
linux-node4
参数解释：
system add 添加一个系统定制
name 定义这个新添加的系统定制的名字
mac 指定MAC
profile 指定profile，通过cobbler profile list查看
ip-address 指定静态IP
subnet 指定子网掩码
gateway 指定网关
interface 指定网卡
static=1 设置为静态IP
hostname 这是主机名
name-servers 设置dns服务器
kickstart 设置kickstart，通过cobbler profile report来查看。（3）开机自动安装
创建一个虚拟机，mac地址为00:50:56:33:F1:45，启动后你就会发现自动进入安装系统了，等安装完以后，所有的配置都和我们当初设置的一样。
11、Cobbler的API
cobbler也是通过restful-api来调用对应的接口，下面请看两个小脚本：
都是采用opython2.7版本运行的
[root@linux-node2 ~]# cat cobbler_list.py
#!/usr/bin/python
import xmlrpclib
server = xmlrpclib.Server("http://192.168.56.12/cobbler_api")
print server.get_distros()
print server.get_profiles()
print server.get_systems()
print server.get_images()
print server.get_repos()使用api的方式，定制安装系统，python脚本如下：
[root@linux-node2 ~]# cat cobbler-api.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import xmlrpclib
class CobblerAPI(object):
def __init__(self,url,user,password):
self.cobbler_user= user
self.cobbler_pass = password
self.cobbler_url = url
def add_system(self,hostname,ip_add,mac_add,profile):
'''
Add Cobbler System Infomation
'''
ret = {
"result": True,
"comment": [],
}
#get token
remote = xmlrpclib.Server(self.cobbler_url)
token = remote.login(self.cobbler_user,self.cobbler_pass)
#add system
system_id = remote.new_system(token)
remote.modify_system(system_id,"name",hostname,token)
remote.modify_system(system_id,"hostname",hostname,token)
remote.modify_system(system_id,'modify_interface', {
"macaddress-eth0" : mac_add,
"ipaddress-eth0" : ip_add,
"dnsname-eth0" : hostname,
}, token)
remote.modify_system(system_id,"profile",profile,token)
remote.save_system(system_id, token)
try:
remote.sync(token)
except Exception as e:
ret['result'] = False
ret['comment'].append(str(e))
return ret
def main():
cobbler = CobblerAPI("http://192.168.56.12/cobbler_api","cobbler","123123")
ret = cobbler.add_system(hostname='cobbler-api-test',ip_add='192.168.56.101',mac_add='00:50:56:33:F1:45',profile='CentOS-7.3-x86_64')
print ret
if __name__ == '__main__':
main()
