3、 ... and 、 The experimental steps

1、 Import epel Source

rmp -ivh epel-release-latest-7.noarch.rpm # Install dependency packages
yum list # Automatically load online update sources

2、 install Cobbler And its related service packages

yum install -y cobbler dhcp tftp-server pykickstart httpd rsync xinetd

3、 modify cobbler Master profile

vim /etc/cobbler/settings
# Modify the following
next_server: 192.168.163.10 # Point to tftp Server's IP, This is the machine IP
server: 192.168.163.10 # Point to cobbler Server's IP, This is the machine IP
manage_dhcp: 1 # Give Way cobbler management dhcp service
manage_rsync: 1 # Give Way cobbler management rsync service
manage_tftpd: 1 # Give Way cobbler management tftp service

4、 Start the relevant services and turn off the firewall and selinux

systemctl start httpd.service # Turn on httpd service
systemctl start cobblerd.service # Turn on cobbler service
systemctl stop firewalld
setenforce 0

5、 Use cobbler check Command to Cobbler Make check settings , Query the items that need to change the configuration

cobbler check

6、 Turn on tftp Service and rsync service

（1） modify tftp Configuration file for
vim /etc/xinetd.d/tftp
disable = no

（2） Opening service
systemctl restart xinetd.service
systemctl start rsyncd.service

7、 Download the boot operating system file

Add the generated key Cobbler In profile
vim /etc/cobbler/settings
default_password_crypted: “$1$123456$wOSEtcyiP2N/IfIl15W6Z0” # Replace this line with the generated secret key “” Contents of Li

modify Cobbler management dhcp Service template file
vim /etc/cobbler/dhcp.template
subnet 192.168.163.0 netmask 255.255.255.0 {
option routers 192.168.163.2; # Modify gateway
option domain-name-servers 192.168.163.2; # modify DNS, If the network card uses dhcp Pattern , It can be done by nslookup 127.0.0.1 | grep server Inquire about DNS Address
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.163.100 192.168.163.200; # Modify the address pool
