本篇内容介绍了“用Cobbler定制化安装指定的系统”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
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
[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 # ****************************************************************** # 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
