Руководство по установке и запуску OpenStack в ALT Linux p8

Инструкция по мотивам установки на Redhat: https://docs.openstack.org/newton/install-guide-rdo/

Инструкция в разработке.

Минимальные требования к оборудованию

Процессорных ядер - одно;
Оперативная память от 4Gb;
Диск 20 Гб.

* На машине с 2Gb RAM - сталкивался с нехваткой памяти и падением процессов.

Пример установки с сетевым модулем на управляющем узле (controller)

- - Сетевые интерфейсы *** !!!! переделать с другой структурой сети
ens19 -
ens20 -

Установка управляющего узла

Добавляем на узле в /etc/hosts (не удаляйте хост 127.0.0.1)

# Управляющий узел
10.0.0.11 controller
# Вычислительный узел
10.0.0.31 compute1

Подготовка к установке

# apt-get update -y
# apt-get dist-upgrade  -y

Удаление firewalld

apt-get remove firewalld

Установка ПО

# apt-get install openstack-nova chrony python-module-memcached python3-module-memcached python-module-pymemcache python3-module-pymemcache mariadb-server python-module-MySQLdb python-module-openstackclient openstack-glance python-module-glance python-module-glance_store python-module-glanceclient  python-module-glanceclient python-module-glance_store  python-module-glance openstack-glance  openstack-nova-api openstack-nova-cells openstack-nova-cert openstack-nova-conductor openstack-nova-console  openstack-nova-scheduler rabbitmq-server  openstack-keystone apache2-mod_wsgi  memcached

настройка времени

в /etc/chrony.conf добавляем

allow 10.0.0.0/24

Если имеется настроенный свой NTP, заменяем "pool.ntp.org" на свой.

pool pool.ntp.org iburst

#systemctl enable chronyd.service
 Synchronizing state of chronyd.service with SysV service script with /lib/systemd/systemd-sysv-install.
 Executing: /lib/systemd/systemd-sysv-install enable chronyd
#systemctl start chronyd.service

настройка sql сервера =

Комментируем строку "skip-networking" в /etc/my.cnf.d/server.cnf

# cat > /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 10.0.0.11
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

# systemctl enable mariadb
# systemctl start mariadb

задаем пароль администратора sql сервера root и удаляем тестовые таблички

пароль по умолчанию пустой "" (после ввода нового пароля, на все вопросы отвечать утвердительно)

# mysql_secure_installation

настройка сервера сообщений rabbitmq

# systemctl enable rabbitmq.service
# systemctl start rabbitmq

Добавляем пользователя:

#rabbitmqctl add_user openstack RABBIT_PASS
#rabbitmqctl set_permissions openstack ".*" ".*" ".*"

Настройка memcached

в файле /etc/sysconfig/memcached заменяем строчку LISTEN="127.0.0.1" на

LISTEN="10.0.0.11"

# systemctl enable memcached
# systemctl start memcached

Настройка Keystone

Создаём базу данных и пользователя с паролем.

# mysql -u root -p
> CREATE DATABASE keystone;
> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'KEYSTONE_DBPASS';
> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'KEYSTONE_DBPASS';

Сохраняем оригинальный конфигурационный файл.

# mv /etc/keystone/keystone.conf /etc/keystone/keystone.conf.orig

# cat >  /etc/keystone/keystone.conf 
[DEFAULT]
[assignment]
[auth]
[cache]
[catalog]

[domain_config]

[eventlet_server]
[eventlet_server_ssl]
[federation]
[fernet_tokens]
[identity]
[identity_mapping]
[kvs]
[ldap]
[matchmaker_redis]

[resource]
[revoke]
[role]
[saml]
[shadow_users]
[signing]
[ssl]
[token]
provider = fernet
[tokenless_auth]
[trust]

Заполняем базу данных keystone

# su -s /bin/sh -c "keystone-manage db_sync" keystone

# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

Пароль пользователя admin - ADMIN_PASS

# keystone-manage bootstrap --bootstrap-password ADMIN_PASS \
 --bootstrap-admin-url http://controller:35357/v3/ \
 --bootstrap-internal-url http://controller:35357/v3/ \
 --bootstrap-public-url http://controller:5000/v3/ \
 --bootstrap-region-id

настраиваем apache2 для keystone

у нас apache2 собран без mod_version, поэтому убираем в файле /etc/httpd2/conf/sites-available/openstack-keystone.conf всё строчки

<IfVersion >= 2.4>
</IfVersion>

добавляем в активную конфигурацию keystone

# a2ensite openstack-keystone

Добавляем servername в конфигурацию.

echo ServerName controller >/etc/httpd2/conf/sites-enabled/servername.conf

systemctl enable httpd2.service
systemctl start httpd2.service

Создание доменов, пользователей и ролей

Для дальнеших работ рекомендуется создать пользователя.

# adduser admin
# su - admin

cat >auth
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3

Создаём пользователя demo

# su - admin
. auth
openstack project create --domain default \
 --description "Service Project"

Укажите пароль для пользователя demo

openstack project create --domain default \
 --description "Demo Project" demo
openstack user create --domain default \
 --password-prompt demo
openstack role create user
openstack role add --project demo --user demo user

Проверка настроек узла управления

# su - admin
$ . auth
unset OS_AUTH_URL OS_PASSWORD

пароль "ADMIN_PASS"

openstack --os-auth-url http://controller:35357/v3 \
 --os-project-domain-name Default --os-user-domain-name Default \
 --os-project-name admin --os-username admin token issue

должно вывести что-то вроде:

Установка вычислительного узла

начальная подготовка управляющего узла

Создание БД.

mysql -u root -p
CREATE DATABASE nova_api;
CREATE DATABASE nova;
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%'   IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

Создаём пользователя nova и указываем пароль, который потом будет использоваться при настройке.

openstack user create --domain default --password-prompt nova

создаём роль

openstack role add --project service --user nova admin

создаём API endpoint

openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1/%\(tenant_id\)s
openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1/%\(tenant_id\)s
