实战-使用 Cobbler 定制化安装指定系统

搭建好 Cobbler 服务器后，我们需要先新建一个 VM 虚拟机，获取 MAC地址。定制主机配置是根据 MAC 地址来识别主机的。

环境：
  release 7.6.1810
VMware Workstation Pro 14

新建VM 虚拟机

MAC 地址为 00:50:56:3E:F0:C6

使用 Cobbler 安装系统时，指定好系统的 IP地址，镜像，网关，主机名等信息

[root@localhost kickstarts]# pwd
/var/lib/cobbler/kickstarts
[root@Jaking kickstarts]# cobbler system add \
--name=Jaking-custom \
--mac=00:50:56:3E:F0:C6 \
--profile=CentOS-7.6-x86_64 \
--ip-address=192.168.1.163 \
--subnet=255.255.255.0 \
--gateway=192.168.1.1 \
--interface=eth0 \
--static=1 \
--hostname=Jaking-custom \
--name-servers="192.168.1.1" \
--kickstart=/var/lib/cobbler/kickstarts/CentOS7.ks

查看 system 列表

[root@Jaking kickstarts]# cobbler system list
   Jaking-custom

同步 Cobbler 配置

[root@Jaking kickstarts]# systemctl restart cobblerd
[root@Jaking kickstarts]# cobbler sync

查看 DHCP 配置，发现 DHCP 服务器，已经加入 IP 和 MAC 的对应关系。

[root@Jaking kickstarts]# cat /etc/dhcp/dhcpd.conf

开机，自动安装指定系统

直接安装无需等待，并且已经预先设置网络相关参数。
输入 root 123456（服务端定义好的密码） 登录系统：

MAC 地址为 00:50:56:3E:F0:C6 的系统获取到了指定的 IP 192.168.1.163
