This article introduces the relevant knowledge of "customizing the installation of designated systems with Cobbler". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Environment:

CentOS Linux release 7.6.1810

VMware Workstation Pro 14

Create a new VM virtual machine

The MAC address is 00:50:56:3E:F0:C6

When installing the system using Cobbler, specify the IP address, image, gateway, hostname and other information of the system.

[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

View system list

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

Synchronize Cobbler configuration

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

Check the DHCP configuration and find that the DHCP server has joined the corresponding relationship between IP and MAC.

[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.

Power on and automatically install the designated system

Direct installation does not need to wait, and network-related parameters have been set in advance.

Enter root 123456 (the password defined by the server) to log in to the system:

The system with MAC address 00:50:56:3E:F0:C6 obtained the specified IP 192.168.1.163
