## Конфигурация сервера
|
||
|
||
### Установка пакетов
|
||
```shell
|
||
apt -y install krb5-kdc krb5-admin-server
|
||
```
|
||
|
||
## Конфигурация клиента
|
||
|
||
### Установка пакетов
|
||
```shell
|
||
apt -y install krb5-user libpam-krb5
|
||
```
|
||
|
||
## Общая конфигурация
|
||
На сервере и клиенте надо проделать следующие шаги:
|
||
|
||
### Смена hostname
|
||
```shell
|
||
hostnamectl set-hostname <hostname>
|
||
```
|
||
|
||
### Правка файла hosts
|
||
Вместо правки файла hosts можно поднять DNS-сервер и сделать записи там.
|
||
```shell
|
||
<server-ip> <server-name.domain.name> <server-name>
|
||
<client-ip> <client-name.domain.name> <client-name>
|
||
|
||
# /etc/hosts
|
||
```
|
||
|
||
### Редактирование конфига Kerberos
|
||
```shell
|
||
[libdefaults]
|
||
default_realm = <DOMAIN.NAME>
|
||
|
||
[realms]
|
||
<DOMAIN.NAME> = {
|
||
kdc = <server-name.domain.name>
|
||
admin_server = <server-name.domain.name>
|
||
kpasswd_server = <server-name.domain.name>
|
||
default_domain = <DOMAIN.NAME>
|
||
}
|
||
|
||
[domain_realm]
|
||
<domain.name> = <DOMAIN.NAME>
|
||
.<domain.name> = <DOMAIN.NAME>
|
||
|
||
# /etc/krb5.conf
|
||
```
|
||
|
||
## Создание нового реалма (на сервере)
|
||
|
||
### Создание master key для БД krb5
|
||
```shell
|
||
krb5_newrealm
|
||
```
|
||
|
||
### Создание учётной записи администратора
|
||
```shell
|
||
kadmin.local
|
||
addprinc <admin-name>/admin
|
||
quit
|
||
```
|
||
|
||
### Разрешение административных прав
|
||
```shell
|
||
<admin-name>/admin
|
||
|
||
# /etc/krb5kdc/kadm5.acl
|
||
```
|
||
|
||
## Получение билета
|
||
```shell
|
||
kinit <admin-name>\admin
|
||
```
|
||
Проверяем наличие выданного билета:
|
||
```shell
|
||
klist
|
||
```
