Most OpenStack services use an SQL database to store information. The database typically runs on the controller node. The procedures in this guide use MariaDB or MySQL depending on the distribution. OpenStack services also support other SQL databases including PostgreSQL.
Примечание
As of Ubuntu 16.04, MariaDB was changed to use the “unix_socket Authentication Plugin”. Local authentication is now performed using the user credentials (UID), and password authentication is no longer used by default. This means that the root user no longer uses a password for local access to the server.
Установите пакеты:
# apt install mariadb-server python-pymysql
Создайте и отредактируйте файл /etc/mysql/mariadb.conf.d/99-openstack.cnf
и выполните следующие действия:
Создайте раздел [mysqld]
и задайте ключу ``bind-address``значение управляющего IP адреса управляющего узла для открытия доступа другими узлами в управляющей сети. Задайте дополнительные ключи для включения полезных опций и набора символов UTF-8:
[mysqld]
bind-address = 10.0.0.11
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
Перезапустите сервис баз данных:
# service mysql restart
Secure the database service by running the mysql_secure_installation
script. In particular, choose a suitable password for the database
root
account:
# mysql_secure_installation
