[root@puppet ~]# 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 : 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.
4 : change 'disable' to 'no' in /etc/xinetd.d/rsync
5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
6 : 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

В дефолтной установке нужен запущенный httpd, без него:

cobbler check
httpd does not appear to be running and proxying cobbler, or SELinux is in the way. Original traceback:

4 : change 'disable' to 'no' in /etc/xinetd.d/rsync

Поправить соответвенно ...

5 : debmirror package is not installed, it will be required to manage debian deployments and repositories

Игнорирую - дебиан мне не нужен

6 : 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

Как и советует подсказка:

openssl passwd -1 -salt 'random-phrase-here' 'swordfish'

и вписать в конфиг

Настройка компонетов системы

Web-управление

В моей установке уже настроено проксирование через апач, аутентификация отключена. Интерфейс доступен https://172.16.250.1/cobbler_web/
Возможна аутентификация через веб-интерфейс несколькими способами: пароль, созданный утилитой htdigest (сохраняется в файле /etc/cobbler/users.digest), Kerberos, LDAP, Spacewalk/Satellite и тестовый (используется для отладки, всегда testing/testing). Но в настройках по умолчанию аутентификация через веб-интерфейс блокирована. Разрешим ее, для примера будем использовать digest-файл. Для чего в файле /etc/cobbler/modules.conf меняем значение параметра module в секции authentication:

[authentication]

1. module = authn_denyall # блокировка аутентификации
2. module = authn_configfile

module = authn_testing
По умолчанию логин и пароль для регистрации – cobbler/cobbler. Его следует изменить при помощи команды:

# htdigest /etc/cobbler/users.digest "Cobbler" cobbler
