实战-使用 Cobbler 定制化安装指定系统

导读搭建好 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:
CentOS Linux 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
[[email protected] kickstarts]# pwd/var/lib/cobbler/kickstarts[[email protected] 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

[[email protected] kickstarts]# cobbler system list   Jaking-custom

同步 Cobbler 配置

[[email protected] kickstarts]# systemctl restart cobblerd[[email protected] 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。

[[email protected] kickstarts]# cat /etc/dhcp/dhcpd.conf# ******************************************************************# Cobbler managed dhcpd.conf file# generated from cobbler dhcp.conf template (Sat Jan  4 10:52:04 2020)# Do NOT make changes to /etc/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
