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.
Install the packages:
# apt install mysql-server python-pymysql
Create and edit the /etc/mysql/conf.d/openstack.cnf
file
and complete the following actions:
Create a [mysqld]
section, and set the bind-address
key to the management IP address of the controller node to
enable access by other nodes via the management network. Set
additional keys to enable useful options and the UTF-8
character set:
[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
Restart the database service:
# service mysql restart
