Cobbler1、Cobbler是一个linux安装服务器，他能实现网络安装环境下的快速安装
基于Python开发的
2、适用于大规模安装linux操作系统，不同版本的操作系统，同一版本又不同的配置
Cobber基于DHCP、PXE、TFTP、HTTP、Kickstart的技术，来提供统一的对外服务，另外还有Cobbler Web界面，不过Cobbler CLI已经满足大部分人需求，本节Cobbler Web不做研究，下节有个简单的Web实际用法。
3、另外Cobbler还可以作为一个本地yum仓库，利用reposync
PXE服务支持
rsync服务
DHCP服务管理
DNS服务管理(可选bind,dnsmasq)
IPMI电源管理
Kickstart服务支持
YUM仓库管理
TFTP(PXE启动时需要)
HTTPD(提供kickstart的安装源，并提供定制化的kickstart配置)
/etc/cobbler/settings : cobbler 主配置文件
/etc/cobbler/iso/: iso模板配置文件
/etc/cobbler/pxe: pxe模板文件
/etc/cobbler/power: 电源配置文件
/etc/cobbler/user.conf: web服务授权配置文件
/etc/cobbler/users.digest: web访问的用户名密码配置文件
/etc/cobbler/dhcp.template : dhcp服务器的的配置末班
/etc/cobbler/dnsmasq.template : dns服务器的配置模板
/etc/cobbler/tftpd.template : tftp服务的配置模板
/etc/cobbler/modules.conf : 模块的配置文件
/var/lib/cobbler/config/: 用于存放distros，system，profiles 等信 息配置文件
/var/lib/cobbler/triggers/: 用于存放用户定义的cobbler命令
/var/lib/cobbler/kickstart/: 默认存放kickstart文件
/var/lib/cobbler/loaders/: 存放各种引导程序 ? 镜像目录
/var/www/cobbler/ks_mirror/: 导入的发行版系统的所有数据
/var/www/cobbler/images/ : 导入发行版的kernel和initrd镜像用于 远程网络启动
/var/www/cobbler/repo_mirror/: yum 仓库存储目录
/var/log/cobbler/installing: 客户端安装日志
/var/log/cobbler/cobbler.log : cobbler日志
cobbler commands 介绍
cobbler check 核对当前设置是否有问题
cobbler list 列出所有的cobbler元素
cobbler report 列出元素的详细信息
cobbler sync 同步配置到数据目录,更改配置最好都要执行下
cobbler reposync 同步yum仓库
cobbler distro 查看导入的发行版系统信息
cobbler system 查看添加的系统信息
cobbler profile 查看配置信息 服务器：centos7
网卡： 仅主机，192.168.146.10
桥接： dhcp
安装服务：cobbler dhcp tftp-server pykickstart httpd
systemctl disable firewalld centos7开机不自启防火墙
systemctl stop firewalld centos7停止防火墙
service iptables stop centos6关闭iptables
service iptables enable centos6开机不自启iptables
sed -i "s/SELINUX=SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config 修改selinux配置文件
reboot 重启生效
关闭虚拟机VM本地dhcp服务，防止和我们安装的dhcp发生冲突
yum install cobbler dhcp tftp-server pykickstart httpd -y 安装本实验需要的软件包yum install cobbler -y
systemctl start cobbler
systemctl enable cobblercobbler check 检查cobbler配置文件
当我们执行这条命令后，通常会报以下8条错误，我们一条条修改即可
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.
384 # of the manpage for how that works
server 192.168.146.10`` 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.
272 # if you do not set this correctly, this will be manifested in TFTP open timeouts.
next_server 192.168.146.103 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp
vim /etc/xinetd.d/tftp
disable =disable改为no 
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.
如果当前节点可以访问互联网，执行“cobbler get-loaders”命令即可；
cobbler get-loaders 下载bootloader 加载程序
否则，需要安装syslinux程序包，而后复制
/usr/share/syslinux/{pxelinux.0,memu.c32}等文件至
/var/lib/cobbler/loaders/目录中 
5 : enable and start rsyncd.service with systemctl
systemctl enable rsyncd
systemctl start rsyncd6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
可以忽略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
--这个配置文件在101行
-- openssl passwd -1
#and put the output between the "" below.
必须要修改这个文件，cobbler check 会报错
default_password_crypted: "$1$3pHPXQL8$VxaAapUajtxI0X610meBl/"8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
可忽略
Restart cobblerd and then run ‘cobbler sync‘ to apply changes.修改完以上6个配置后，可执行 cobbler sync 命令
修改cobbler配置
vim /etc/cobbler/settings 将dhcp服务由cobbler托管
仅修改以下配置文件
首先挂载光盘
mount /dev/sr0 /mnt/centos7/ 挂载CentOS7镜像文件
mount /dev/sr1 /mnt/centos6/ 挂载CentOS6镜像文件导入光盘
cobbler import --name=CentOS6.10 --path=/mnt/centos6 --arch=x86_64
cobbler import --name=CentOS7.6 --path=/mnt/centos7 --arch=x86_64 --name 为安装源定义一个名字
--path 镜像文件路径
--arch 安装源的架构centos7
cneots6 
安装源的唯一标识就是name参数定义的，以上面为例。导入后唯一标识就是
基于epel源，安装system-config-kickstart程序包
yum install system-config-kickstart 基于图形化界面来制作kickstart文件
也可以参考当前主机上的应答模板文件 /root/anaconda-ks.cfg
制作完kickstart文件后，建议检查一下语法错误
cobbler validateks将原来的配置修改文 url --url="$tree"
将制作好的kickstart文件导入到/var/lib/cobbler/kickstarts/(默认存放kickstart文件) 目录下
cp /data/ks7_mini.cfg /var/lib/cobbler/kickstart/
cp /data/ks6_mini.cfg /var/lib/cobbler/kickstart/cobbler profile edit --name Centos7.6-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks7_mini.cfg
cobbler profile edit --name Centos6.10-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks6_mini.cfg
我们还可以修改CentOS7的默认网卡名称
cobbler profile edit --name Centos7.6-x86_64 --kopts=‘net.ifnames=0 biosdevname=0‘ 同步cobbler
cobbler sync
systemctl restart httpd
systemctl restart dhcpd
systemctl restart tftp
systemctl restart cobblerd
systemctl restart xinetd.service
如有错误或不清晰的地方，请各位指正。
