389-ds

Настройка сервера каталогов 389-ds (http://directory.fedoraproject.org/)

Первоначальная настройка

Примечание: Помните, что если стандартный порт LDAP 389 занят, то будет использован случайный порт c 1024 до 65535. Проверить впоследствии:

ss -nlp | awk '/ns-slapd/ { print substr($5,4) }'

Хорошей практикой будет установка номера порта 390.

1. Установка

apt-get install 389-ds

2. Адаптация окружения:

2.1. Создайте файл /etc/sysctl.d/389-ds.conf:

fs.file-max = 64000
net.ipv4.tcp_keepalive_time = 60

2.2. В /etc/security/limits.conf добавьте:

*                soft    nofile          2048

2.3 Примените изменения:

sysctl -p /etc/sysctl.d/389-ds.conf

Выйти и зайти в сеанс root (для принятия нового лимита открытых файлов).

Запустите проверку окружения для 389-ds:

dsktune -q

В случае готового окружения ничего не будет выведено.

3. Создание экземпляра каталога

Внимание! Для управления сервером через консоль управления 389-console необходимо начать развёртывание скриптом setup-ds-admin.pl

[root@c228 ~]# setup-ds.pl

==============================================================================
This program will set up the 389 Directory Server.

It is recommended that you have "root" privilege to set up the software.
Tips for using this  program:
  - Press "Enter" to choose the default and go to the next screen
  - Type "Control-B" or the word "back" then "Enter" to go back to the previous screen
  - Type "Control-C" to cancel the setup program

Would you like to continue with set up? [yes]: yes

==============================================================================
Your system has been scanned for potential problems, missing patches,
etc.  The following output is a report of the items found that need to
be addressed before running this software in a production
environment.

389 Directory Server system tuning analysis version 23-FEBRUARY-2012.

NOTICE : System is x86_64-unknown-linux3.10.30-std-def-alt1 (1 processor).

NOTICE : The net.ipv4.tcp_keepalive_time is set to 7200000 milliseconds
(120 minutes).  This may cause temporary server congestion from lost
client connections.

WARNING: There are only 1024 file descriptors (soft limit) available, which
limit the number of simultaneous connections.  

WARNING  : The warning messages above should be reviewed before proceeding.

Would you like to continue? [no]: yes

==============================================================================
Choose a setup type:

   1. Express
       Allows you to quickly set up the servers using the most
       common options and pre-defined defaults. Useful for quick
       evaluation of the products.

   2. Typical
       Allows you to specify common defaults and options.

   3. Custom
       Allows you to specify more advanced options. This is 
       recommended for experienced server administrators only.

To accept the default shown in brackets, press the Enter key.

Choose a setup type [2]: 2

==============================================================================
Enter the fully qualified domain name of the computer
on which you're setting up server software. Using the form
<hostname>.<domainname>
Example: eros.example.com.

To accept the default shown in brackets, press the Enter key.

Warning: This step may take a few minutes if your DNS servers
can not be reached or if DNS is not configured correctly.  If
you would rather not wait, hit Ctrl-C and run this program again
with the following command line option to specify the hostname:

    General.FullMachineName=your.hostname.domain.name

Computer name [c228.school.alt]: 

==============================================================================
The server must run as a specific user in a specific group.
It is strongly recommended that this user should have no privileges
on the computer (i.e. a non-root user).  The setup procedure
will give this user/group some permissions in specific paths/files
to perform server-specific operations.

If you have not yet created a user and group for the server,
create this user and group using your native operating
system utilities.

System User [nobody]: 
System Group [nobody]: 

==============================================================================
The standard directory server network port number is 389.  However, if
you are not logged as the superuser, or port 389 is in use, the
default value will be a random unused port number greater than 1024.
If you want to use port 389, make sure that you are logged in as the
superuser, that port 389 is not in use.

Directory server network port [389]: 

==============================================================================
Each instance of a directory server requires a unique identifier.
This identifier is used to name the various
instance specific files and directories in the file system,
as well as for other uses as a server instance identifier.

Directory server identifier [c228]: 

==============================================================================
The suffix is the root of your directory tree.  The suffix must be a valid DN.
It is recommended that you use the dc=domaincomponent suffix convention.
For example, if your domain is example.com,
you should use dc=example,dc=com for your suffix.
Setup will create this initial suffix for you,
but you may have more than one suffix.
Use the directory server utilities to create additional suffixes.

Suffix [dc=school,dc=alt]: 

==============================================================================
Certain directory server operations require an administrative user.
This user is referred to as the Directory Manager and typically has a
bind Distinguished Name (DN) of cn=Directory Manager.
You will also be prompted for the password for this user.  The password must
be at least 8 characters long, and contain no spaces.
Press Control-B or type the word "back", then Enter to back up and start over.

Directory Manager DN [cn=Directory Manager]: 
Password: 
Password (confirm): 

Управление службой

В новых версиях

Запуск:

service dirsrv start

Остановка:

service dirsrv stop

В старых версиях (p7)

Запуск:

service fedora-ds start

Остановка:

service fedora-ds stop

Использование консоли управления

Для 389-ds есть консоль управления с графическим интерфейсом (пакет 389-console). Для управления потребуется развернуть 389-admin и настроить административный сервер. Этот сервер работает по умолчанию на порту 9830 и доступен как через графическую консоль, так и через веб-браузер (но уже только для статистики и просмотра журналов).

Внимание! Для успешного развёртывания 389-admin необходимо выключить и удалить все экземпляры 389-ds.

Удаление экземпляров 389-ds

service dirsrv stop
rm -rf /etc/dirsrv /var/lib/dirsrv /var/log/dirsrv
killall ns-slapd

Запуск мастера установки 389-admin

setup-ds-admin.pl

Во время установки будут запрошены пароли для администратора административного сервера (admin) и администратора базы данных (cn=Directory Manager). Входить можно под обоими учётными записями.

Запуск программы

1. Установите 389-console:

apt-get install 389-console 389-ds-console fonts-ttf-liberation xauth

2. Запустите 389-console на сервере (например, зайдя туда по ssh -Y с графической станции Linux):

389-console -u admin -a localhost:9830

3. В появившемся диалоговом окне укажите имя пользователя (User ID:): admin или cn=Directory Manager), пароль и адрес административного сервера (Administration URL): localhost:9830

Быстрое развёртывание 389-ds и 389-admin

Параметры сервера:

Параметр	Значение
Домен	school.alt
Имя сервера	c228.school.alt
Порт LDAP	390
Порт администрирования	9830
Пароль	12345678

1. Создаём файл 389-ds-admin-setup.inf следующего содержимого:

[General]
AdminDomain = school.alt
ConfigDirectoryAdminID = admin
ConfigDirectoryAdminPwd = 12345678
ConfigDirectoryLdapURL = ldap://c228.school.alt:390/o=NetscapeRoot
FullMachineName = c228.school.alt
SuiteSpotGroup = nobody
SuiteSpotUserID = nobody
[admin]
Port = 9830
ServerAdminID = admin
ServerAdminPwd = 12345678
SysUser = nobody
[slapd]
HashedRootDNPwd = {SSHA}2DwlOV3BftpZQhZEAA7ai0oLPwn9lwsnKrGh7A==
InstallLdifFile = suggest
RootDN = cn=Directory Manager
RootDNPwd = 12345678
ServerIdentifier = c228
ServerPort = 390
Suffix = dc=school,dc=alt
UseExistingMC = 0
ds_bename = userRoot

2. Создаём экземпляры сервера администрирования и LDAP:

setup-ds-admin.pl --file 389-ds-admin-setup.inf --silent

3. Проверяем запуск служб и наличие открытых портов:

[root@c228 ~]# service dirsrv status
dirsrv c228 (pid 31648) is running...
[root@c228 ~]# service dirsrv-admin status
dirsrv-admin (pid 31740) is running...
[root@c228 ~]# ss -lnp|egrep ':(390|9830)'
tcp    LISTEN     0      128                    *:9830                  *:*      users:(("httpd2.worker",31744,3),("httpd2.worker",31740,3))
tcp    LISTEN     0      128                   :::390                  :::*      users:(("ns-slapd",31648,6))
[root@c228 ~]# ldapsearch -H ldap://c228:390 -x | grep ^result:
result: 0 Success
