安装

# 源码安装
sudo apt install git make python-dev python-setuptools python-cheetah openssl
sudo apt install createrepo apache2  python-cheetah python-netaddr python-simplejson python-urlgrabber python-yaml rsync  yum-utils  libapache2-mod-wsgi xinetd tftpd tftp python-django
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod rewrite
sudo a2ensite cobbler.conf

sudo apt install make git python3-yaml python3-cheetah python3-netaddr python3-simplejson python3-future python3-distro python3-setuptools python3-sphinx python3-coverage pyflakes3 python3-pycodestyle python3-django




git clone https://github.com/cobbler/cobbler.git
cd cobbler
git checkout release28

本来Google的方案需要从源码安装，但是尝试了下apt，发现有现成的包，~~所以简单太多了~~ 版本太老，有额外的问题要处理.

sudo apt install cobbler cobbler-web xinetd
# 安装过程中会让输密码
# 该包是2.6.6版本 有点老，现在来说有好几个bug
# cobbler-web 有bug， 不兼容新的
sudo pip install Django==1.8.9

# 结果输出
Setting up liblwp-protocol-https-perl (6.07-2) ...
Setting up debmirror (1:2.32) ...
Setting up cobbler (2.6.6+dfsg1-13) ...
Considering dependency proxy for proxy_http:
Enabling module proxy.
Enabling module proxy_http.
To activate the new configuration, you need to run:
  systemctl restart apache2
Module wsgi already enabled
Enabling module rewrite.
To activate the new configuration, you need to run:
  systemctl restart apache2
ERROR: Module python does not exist!
Enabling site cobbler.
To activate the new configuration, you need to run:
  systemctl reload apache2
Created symlink /etc/systemd/system/multi-user.target.wants/cobbler.service → /lib/systemd/system/cobbler.service.
# 在重启前需要配置cobbler

配置

# 配置文件 /etc/cobbler/settings

# 自动化部署系统的密码的哈希, 用下行命令生成
# openssl passwd -1
# $1$j9.kasLF$4v5dJWXMDUmxYTXO9qPiG.
# 密文第一项 1 指hash方式， 第二项 j9.kasLF 指的salt，这样子用以系统判断密码是否正确但是又不存储密码，密码和salt都相同时才能计算出唯一的密文
default_password_crypted: "$1$j9.kasLF$4v5dJWXMDUmxYTXO9qPiG."

# 设置cobbler的ip， 不要设置0.0.0.0，设置一个不隔离广播域的内网ip
server: 192.168.1.2
# 设置的tftp ip，用于下载镜像，通常与上一个一样
next_server: 192.168.1.2

# 是否开启DHCP，0不开启 1开启
# 为了启动 pxe， 需要开启dhcp分发地址 并引导系统 到tftp server下载网络启动文件
manage_dhcp: 1

# 配置DHCP /etc/cobbler/dhcp.template
# 不要修改 next-server 项，该配置会自动从上面拉取变量
# 不要修改 #for dhcp_tag in $dhcp_tags.keys(): 这一行之后的内容
subnet 192.168.1.0 netmask 255.255.255.0 {
     option routers             192.168.1.1;
     option domain-name-servers 114.114.114.114,8.8.8.8;
     option subnet-mask         255.255.255.0;
     filename                   "/pxelinux.0";
     default-lease-time         2.8.0;
     max-lease-time             43200;
     next-server                $next_server;
}

#  树莓派版本用的dnsmasq，所以改这个
#  配置DHCP /etc/cobbler/dnsmasq.template

cobbler 会将镜像存储到 /var/lib/cobbler/www/cobbler/ks_mirror/下，注意容量和权限

sudo systemctl enable cobbler
sudo systemctl start cobbler
# 检测 会提示一些操作， 根据需要去做
sudo cobbler check
sudo cobbler sync
# 会发现该指令报错 缺pxelinux.0等一批loaders
