1. Cobbler介绍
参考链接：http://blog.oldboyedu.com/autoinstall-cobbler/
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)
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环境准备与部署

2.2 配置Cobbler
#配置文件
/etc/cobbler/settings [root@linux-node1 ~]# /etc/init.d/httpd restart
停止 httpd： [失败]
正在启动 httpd： [确定]
[root@linux-node1 ~]# /etc/init.d/cobblerd start
Starting cobbler daemon: [确定]
[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/etc/init.d/cobblerd restart
The following are potential configuration items that you may want to fix:
: 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.
: 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.
: 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., menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
: change 'disable' to 'no' in /etc/xinetd.d/rsync
: debmirror package is not installed, it will be required to manage debian deployments and repositories
: 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
: 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。
[root@linux-node1 ~]# cp /etc/cobbler/settings{,.ori} # 备份
# server，Cobbler服务器的IP。
sed -i 's/server: 127.0.0.1/server: 10.0.0.7/' /etc/cobbler/settings
# next_server，如果用Cobbler管理DHCP，修改本项，作用不解释，看kickstart。
sed -i 's/next_server: 127.0.0.1/next_server: 10.0.0.7/' /etc/cobbler/settings
# 用Cobbler管理DHCP
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。
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。

cobbler check 及解决过程详细
简要步骤命令：
备份文件
- cp /etc/cobbler/settings{,.ori}
修改配置
sed -i 's/server: 127.0.0.1/server: 172.16.1.101/' /etc/cobbler/settings
sed -i 's/next_server: 127.0.0.1/next_server: 172.16.1.101/' /etc/cobbler/settings
sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings
sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings
#默认密码
sed -ri "/default_password_crypted/s#(.*: ).*#\1\"`openssl passwd -1 -salt 'lewen' '123456'`\"#" /etc/cobbler/settings
sed -i 's#yes#no#' /etc/xinetd.d/rsync
sed -i 's#yes#no#' /etc/xinetd.d/tftp cobbler get-loaders
2.3 配置DHCP模板
只能执行一遍的命令
cp /etc/cobbler/dhcp.template{,.bak}
sed -i.ori 's#192.168.1#172.16.1#g;22d;23d' /etc/cobbler/dhcp.template
查看：
vim /etc/cobbler/dhcp.template
subnet 172.16.1.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
range dynamic-bootp 172.16.1.100 172.16.1.200;

3.2 导入镜像
方式1：命令行导入
[root@linux-node1 ~]# mount /dev/cdrom /mnt/ # 挂载CentOS6.10的系统镜像。
# 导入系统镜像
[root@linux-node1 ~]# cobbler import --path=/mnt/ --name=CentOS-7.1-x86_64 --arch=x86_64
# --path 镜像路径
# --name 为安装源定义一个名字
# --arch 指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64
# 安装源的唯一标示就是根据name参数来定义，本例导入成功后，安装源的唯一标示就是：CentOS-7.1-x86_64，如果重复，系统会提示导入失败。
[root@linux-node1 ~]# cobbler distro list # 查看镜像列表
CentOS-7.1-x86_64
# 镜像存放目录，cobbler会将镜像中的所有安装文件拷贝到本地一份，放在/var/www/cobbler/ks_mirror下的CentOS-7.1-x86_64目录下。因此/var/www/cobbler目录必须具有足够容纳安装文件的空间。
[root@linux-node1 ~]# cd /var/www/cobbler/ks_mirror/
[root@linux-node1 ks_mirror]# ls

4.Cobbler的Web管理界面的安装与配置
安装系统
自定义安装系统 官网：http://cobbler.github.io/manuals/2.6.0/
对要安装的系统进行定制
已经安装cobbler-web软件。
访问网址：http://10.0.0.101/cobbler_web和https://10.0.0.101/cobbler_web
默认用户名：cobbler
默认密码 ：cobbler
/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
[root@linux-node1 ~]# cat /etc/cobbler/users.digest
cobbler:Cobbler:a2d6bae81669d707b72c0bd9806e01f3
# 设置Cobbler web用户登陆密码
# 在Cobbler组添加cobbler用户，提示输入2遍密码确认
[root@linux-node1 ~]# htdigest /etc/cobbler/users.digest "Cobbler" cobbler
Changing password for user cobbler in realm Cobbler
New password:
Re-type new password:
[root@linux-node1 ~]# cobbler sync
[root@linux-node1 ~]# /etc/init.d/httpd restart
停止 httpd： [确定]
正在启动 httpd： [确定]
[root@linux-node1 ~]# /etc/init.d/cobblerd restart
Stopping cobbler daemon: [确定]
Starting cobbler daemon:
命令端配置cobbler密码
主机名，系统文件，ks文件
网卡配置
这里将要安装的虚拟机（或主机）网卡eth0和eth1的Mac地址填到，定制系统的Mac栏
分别依次添加网卡的mac地址
创建完记得保存同步
然后开启被安装的机器，就会自动通过DHCP获得IP,下载文件，安装系统
当再次安装时，重新定制化，就行
