1.简介
1.1Cobbler
linux系统安装服务，可以通过网络启动（PXE）方式快速安装、重装物理服务器和虚拟机，同时管理DNS、DHCP等。既可以使命令行方式管理，也可以给予web界面管理工具。同时提供API接口，可以方便二次开发使用，是较早的kickstart的升级版，比较容易配置，自带web界面比较易于管理。
2.环境准备
[root@CentOS 7 ~]# cat /etc/redhat-release

3.部署Cobbler服务
3.1添加yum源
curl -o /etc/yum.repos.d/CentOS-Base.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
3.2安装相关服务
[root@CentOS 7 ~]# yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd python-django
3.3修改/etc/cobbler/settings中的server项
[root@CentOS 7 ~]# sed -i 's#server: 127.0.0.1#server: 172.16.1.201#' /etc/cobbler/settings
3.4修改/etc/cobbler/settings中的next_server项
[root@CentOS 7 ~]# sed -i 's/next_server: 127.0.0.1/next_server: 172.16.1.202/' /etc/cobbler/settings
3.5下载所有需要的网络启动文件（需要先启动cobbler服务，国外网站，下载速度巨慢，或者下载失败）
cobbler get-loaders
3.6修改密码
[root@CentOS 7 ~]# sed -ri "/default_password_crypted/s#(.*: ).*#\1\"`openssl passwd -1 -salt 'fengyu' '123456'`\"#" /etc/cobbler/settings
3.7配置Cobbler统一管理DHCP
root@CentOS 7 ~]# sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings
3.8防止误重装
[root@CentOS 7 ~]# sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings
3.9配置DHCP Cobbler模板
[root@CentOS 7 ~]# sed -i.ori 's#192.168.1#172.16.1#g;22d;23d' /etc/cobbler/dhcp.template
3.10启动相关服务
[root@CentOS 7 ~]# systemctl start rsyncd
[root@CentOS 7 ~]# systemctl start tftp.socket
[root@CentOS 7 ~]# systemctl start cobblerd.service
[root@CentOS 7 ~]# cobbler sync
4.web界面操作
4.1浏览器访问https://10.0.0.201/cobbler_web
