一.部署安装cobbler
yum安装cobbler
[root@localhost ~]# yum install -y net-tools
[root@localhost ~]# yum install -y httpd dhcp tftp cobbler cobbler-web
[root@localhost ~]# yum install xinetd
[root@localhost ~]# systemctl start httpd
[root@localhost ~]# systemctl enable httpd
[root@localhost ~]# systemctl start cobblerd
[root@localhost ~]# systemctl enable cobblerd
1.编辑cobbler配置文件
[root@localhost ~]# vim /etc/cobbler/settings
....................
server: 192.168.4.15
next_server: 192.168.4.15
....................
virt_auto_boot: 1
....................
2.持续安装所需文件
[root@localhost ~]# cobbler get-loaders
3.配置tftp
[root@localhost ~]# vim /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
[root@localhost ~]# systemctl enable rsyncd
[root@localhost ~]# systemctl start rsyncd
启动xinetd
[root@localhost ~]# systemctl restart xinetd
[root@localhost ~]# systemctl enable xinetd
4.安装pykickstart
[root@localhost ~]# yum install pykickstart -y
5.设置密码
设置密码、随机值123456 密码123456
[root@localhost ~]# openssl passwd -1 -salt '123456' '123456'
$1$123456$wOSEtcyiP2N/IfIl15W6Z0
更改默认密码为：
[root@localhost ~]# vim /etc/cobbler/settings
default_password_crypted: "$1$123456$wOSEtcyiP2N/IfIl15W6Z0"
[root@localhost ~]# systemctl restart cobblerd
6.cobbler管理DHCP
[root@localhost ~]# vim /etc/cobbler/settings
manage_dhcp: 1
第一次修改模板文件。修改模板文件，生成dhcp配置文件。大致更改的地方有
[root@localhost ~]# vim /etc/cobbler/dhcp.template
subnet 192.168.4.0 netmask 255.255.255.0 {
option routers 192.168.4.2;
option domain-name-servers 192.168.4.2;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.4.100 192.168.4.254;
...................
重启cobblerd
[root@localhost ~]# systemctl restart cobblerd
[root@localhost ~]# cobbler sync
7.编辑启动应用服务脚本
[root@localhost ~]# vim start.sh
#!/bin/bash
systemctl restart httpd
systemctl restart dhcpd
systemctl restart tftp
systemctl restart cobblerd
systemctl restart xinetd
systemctl restart rsyncd
二、镜像导入以及自动化文件必读须知
preseed文件参考网址如下：
- 模板位置：http://www.debian.org/releases/wheezy/example-preseed.txt
- 官方的安装手册：http://www.debian.org/releases/wheezy/i386/
live、desktop的ubuntu18.04镜像不能使用cobller做为iso导入。请使用server-amd64。附带下载连接地址如下：
- http://cdimage.ubuntu.com/releases/
cobbler+ubuntu不能使用kickstart的cfg文件的格式，做为自动化菜单安装的实现文件。ubuntu操作系统使用ks.cfg文件会被强制转为preseed文件内容实现。所以，附带以下ubuntu.seed文件内容跟，参考。

以下有此两个信息检查信息提示，不必在意
The following are potential configuration items that you may want to fix:
1 : One or more repos need to be processed by cobbler reposync for the first time before kickstarting against them: Ubuntu-18.04.3-x86_64, Ubuntu-18.04.3-hwe-x86_64
2 : 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.
