Experiment

Initialization: iptables | firewalld,selinux,ntp | chrony

1 download package (cobbler includes tftp and http, but does not include dhcp)

Yum install cobbler dhcp

Systemctl start tftp httpd # dhcp cannot be started without making changes to the configuration file

2 check the configuration of cobbler, and you can modify the configuration file according to the inspection results

Clbbler check

3 modify the configuration of cobbler

Vim / etc/cobbler/settings

Default_password_crypted: "$1 *" # set the password for root, which can be generated using the command openssl passwd-1 * *

Server: 10.10.10.254 # the address of the cobbler server is set here

Netxt_server: 10.10.10.254 # this is the address of the tftp server

Manage_dhcp: 1

Systemctl restart cobblerd # restart the cobbler service

Cobbler get-loaders # download Startup menu

Cobbler sync # synchronizes the configuration to the data directory. It is best to change the configuration by following. An error may be reported here. After configuring the dhcp service, you can synchronize.

4 configure DHCP service (take the 10.10.10.0 network segment as an example)

Vim / etc/cobbler/dhcp.template

Subnet 10.10.10.0 netmask 255.255.255.0 {

Option routers 10.10.10.254; # Gateway address

Option domain-name-servers 180.76.76.76; # dns address

Range 10.10.10.1 10.10.10.200;} # assigned network address pool (here must be on the same network segment as the local machine)

Synchronize and restart dhcp after this process is completed

Cobbler sync

Systemctl start dhcpd

5 Import os (image) file (after the import is complete, you can use the command cobbler distro to view the imported distribution system information)

Cobbler import-arch=x86_64-path=/misc/cd-name=CentOS7-x86_64

Cobbler import-- arch=x86_64-- path=/mnt/-- name=CentOS6-x86_64 # use cobbler system list to view the values behind name

6 Import the homemade kickstart file into the shared folder and modify it (there is a default kickstart file under this folder, so you can install a minimally installed system at this step)

Vim / var/lib/cobbler/kickstarts/***.cfg

Url-url=$tree

7 make startup menu (modify the default value in / var/lib/tftpboot/pxelinux.cfg/default file)

Cobbler profile add-name=CentOS7.6-x86_64_mini-distro=CentOS7.6-x86_64-kickstart=/var/lib/cobbler/kickstarts/ks7_mini.cfg
