1, Cobbler installation
1.1 basis of preparation environment
Check the current system version
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
Close selinux firewall
[root@localhost ~]# vim /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
[root@localhost ~]# setenforce 0
Close ebtables firewalld firewall
[root@localhost ~]# systemctl stop ebtables firewalld
[root@localhost ~]# systemctl disable ebtables firewalld
Installed base epel source
[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@localhost ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
2. Install the cobbler Service
2.1 and various components mounted cobbler
[root@localhost ~]# yum -y install cobbler cobbler-web pykickstart httpd dhcp tftp rsync xinetd

4. Start httpd service and cobbler
[root@localhost ~]# systemctl start httpd cobblerd
[root@localhost ~]# systemctl enable httpd cobblerd
The detection performed cobbler
[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment: https://github.com/cobbler/cobbler/wiki/Selinux
4 : change 'disable' to 'no' in /etc/xinetd.d/tftp
[root@localhost ~]# systemctl restart xinetd.service
5 : Some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
6 : enable and start rsyncd.service with systemctl
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
8 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
9 : fencing tools were not found, and are required to use the (optional) power management features. install cmanor fence-agents to use them
Restart cobblerd and then run 'cobbler sync' to apply changes.
6. Restart cobbler service, and cobbler sync synchronize
[root@localhost ~]# systemctl restart cobblerd
[root@localhost ~]# cobbler sync
7. Re-detection
[root@localhost ~]# cobbler check
No configuration problems found. All systems go. ## did not find configuration problems. All systems are go.
[root@localhost ~]#
8. Using cobbler to manage, configure DHCP service, modify cobbler profile
[root@localhost ~]# vim /etc/cobbler/settings
manage_dhcp: 1
9. The configuration of the DHCP stencil cobbler
[root@localhost ~]# vim /etc/cobbler/dhcp.template
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option domain-name-servers 192.168.1.1;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.1.100 192.168.1.254;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
10. restart the cobbler Service
[root@localhost ~]# systemctl restart cobblerd
11. Add the user management cobbler
[root@localhost ~]# htdigest -c /etc/cobbler/users.digest Cobbler cobbler
Adding password for cobbler in realm Cobbler.
New password:
Re-type new password:
[root@localhost ~]# systemctl restart cobblerd httpd
12. Open a web browser management interface
Solving steps:
1. SSL logs being given as follows:
[root@localhost ~]# tail -f /var/log/httpd/ssl_error_log

2. Check the cobbler's configuration file py
[root@localhost ~]# sed -n '38,41p' /usr/share/cobbler/web/settings.py
if django.VERSION[0] == 1 and django.VERSION[1] < 4:
ADMIN_MEDIA_PREFIX = '/media/'
else:
STATIC_URL = '/media/'
[root@localhost ~]# sed -n '89p' /usr/share/cobbler/web/settings.py
from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS
3. The initial judgment should be pythone-django version of the problem
