[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:
1: some network boot-loaders are missing from /var/lib/cobbler/loaders. 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, and yaboot.
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.
//第一个问题我们已经解决过了，第二第三个问题是在Debian系统上面需要注意的，解决办法是在Debian系统上面安装fence-agents，可以忽略
//配置DHCP模板文件
[root@localhost ~]# vim /etc/cobbler/dhcp.template

//如果是在生产环境中，那么cobbler的部署已经完成了，但是在VMware虚拟机中还需要做如下操作
[root@localhost ~]# cd /usr/share/cobbler/bin/
[root@localhost bin]# ls
migrate-data-v2-to-v3.py migrate-settings.sh mkgrub.sh settings-migration-v1-to-v2.sh
[root@localhost bin]# bash mkgrub.sh
[root@localhost bin]# cd /var/lib/cobbler/loaders/
[root@localhost loaders]# ls
grub ldlinux.c32 menu.c32 pxelinux.0
[root@localhost loaders]# cobbler sync
[root@localhost loaders]# systemctl restart httpd cobblerd rsyncd dhcpd
手动安装
创建一个虚拟机，然后打开虚拟机，等待dhcp分配完毕，选择想要使用的镜像
密码就是上面执行命令所用的密码
自动安装
通过web管理界面进行自动安装，先新建一个虚拟机
在浏览器输入：https:// + ip地址/cobbler_web
用户名和密码都为:cobbler
将生成出来的mac地址复制保存下来点击左上角的save保存
同步，右上角有同步日志
这里也可以查看日志
将刚才保存下来的Mac地址复制到即将安装的虚拟机上
打开虚拟机，进行安装,等待安装完成后，进行验证
