# Cobbler自动化安装
[Cobbler官网](http://cobbler.github.io)
## 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，是用来实现运维自动化的必备神器。Cobbler可用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，可用方便二次开发使用。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，但它也支持和其他配置管理系统集成，如puppet，暂时不支持saltstack。
## 环境部署准备
```
[root@linux-node1 ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[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 ~]# hostname
linux-node1.example.com
[root@linux-node1 ~]# ifconfig eth0|awk -F ‘[ :]+‘ ‘NR==2{print $3}‘
192.168.56.11
```
## 安装配置Cobbler
```
[root@linux-node1 ~]# yum install cobbler cobbler-web dhcp tftp-server pykickstart httpd -y
[root@linux-node1 ~]# systemctl restart httpd
[root@linux-node1 ~]# systemctl restart cobblerd
[root@linux-node1 ~]# cobbler check
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 ~]# sed -i ‘s/server: 127.0.0.1/server: 192.168.56.11/‘ /etc/cobbler/settings
[root@linux-node1 ~]# sed -i ‘s/server: 127.0.0.1/server: 192.168.56.11/‘ /etc/cobbler/settings
[root@linux-node1 ~]# sed -i ‘s/manage_dhcp: 0/manage_dhcp: 1/‘ /etc/cobbler/settings
[root@linux-node1 ~]# sed -i ‘s/pxe_just_once: 0/pxe_just_once: 1/‘ /etc/cobbler/settings
[root@linux-node1 ~]# openssl passwd -1 -salt ‘91guoxin‘ ‘123456‘
$1$91guoxin$prqpocNRfiZKPDgyIW4851
[root@linux-node1 ~]# vim /etc/cobbler/settings
default_password_crypted: "$1$91guoxin$prqpocNRfiZKPDgyIW4851"
```
第3个问题：
```
[root@linux-node1 ~]# cobbler get-loaders
[root@linux-node1 ~]# ls /var/lib/cobbler/loaders/
COPYING.elilo COPYING.yaboot grub-x86_64.efi menu.c32 README
COPYING.syslinux elilo-ia64.efi grub-x86.efi pxelinux.0 yaboot
[root@linux-node1 ~]# vim /etc/xinetd.d/tftp
disable = no
[root@linux-node1 ~]# systemctl restart tftp
[root@linux-node1 ~]# systemctl restart cobblerd
```
修改Cobbler的dhcp模板，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
subnet 192.168.56.0 netmask 255.255.255.0 {
option routers 192.168.56.2;
option domain-name-servers 192.168.56.2;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.56.100 192.168.56.254;
```
执行`cobbler sync`
```
[root@linux-node1 ~]# cobbler sync

```
再次执行`cobbler check`
```
[root@linux-node1 ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : enable and start rsyncd.service with systemctl
2 : debmirror package is not installed, it will be required to manage debian deployments and repositories
3 : 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.
```
剩余三个问题：
* 1.可用不用理会，因为我们不用rsync同步ISO
* 2.和debian系统相关，不需要
* 3.fence设备相关，不需要
设置开机自启动：
```
[root@linux-node1 ~]# systemctl enable httpd.service
[root@linux-node1 ~]# systemctl enable tftp.service
[root@linux-node1 ~]# systemctl enable cobblerd.service
[root@linux-node1 ~]# systemctl enable dhcpd.service
```

安装系统
新建一台虚拟机：
修改Cobbler提示
```
[root@linux-node1 ~]# vim /etc/cobbler/pxe/pxedefault.template
MENU TITLE Cobbler | http://www.wanyuetian.com
[root@linux-node1 ~]# cobbler sync
```
## 定制化安装
可能有人想kickstart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。
```
[root@linux-node1 ~]# cobbler system add --name=cobblertest --mac=00:0C:29:76:73:2D --profile=CentOS-7.2-x86_64 --ip-address=192.168.56.100 --subnet=255.255.255.0 --gateway=192.168.56.2 --interface=eth0 --static=1 --hostname=cobblertest.example.com --name-servers="192.168.56.2"
[root@linux-node1 ~]# cobbler sync
```
再次开机，如下图所示：
## Cobblerd的web管理界面
