The PDF build does not include content multiple times if the same file is included in a toctree more than once. That means we need to restructure the guide to handle the common parts differently. This approach merges some of the previously split sections back together using inline prose to indicate where minor variations apply for different operating systems but retaining separate files for cases where the differences are significant.

Red Hat SQL database
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
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 <https://www.postgresql.org/>`__.
|
|
|
|
|
|
Install and configure components
|
|
--------------------------------
|
|
|
|
#. Install the packages:
|
|
|
|
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install mariadb mariadb-server python2-PyMySQL
|
|
|
|
.. end
|
|
|
|
|
|
|
|
|
|
|
|
|
|
2. Create and edit the ``/etc/my.cnf.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:
|
|
|
|
.. path /etc/my.cnf.d/openstack.cnf
|
|
.. code-block:: ini
|
|
|
|
[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
|
|
|
|
.. end
|
|
|
|
|
|
Finalize installation
|
|
---------------------
|
|
|
|
|
|
|
|
#. Start the database service and configure it to start when the system
|
|
boots:
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable mariadb.service
|
|
# systemctl start mariadb.service
|
|
|
|
.. end
|
|
|
|
|
|
|
|
|
|
2. Secure the database service by running the ``mysql_secure_installation``
|
|
script. In particular, choose a suitable password for the database
|
|
``root`` account:
|
|
|
|
.. code-block:: console
|
|
|
|
# mysql_secure_installation
|
|
|
|
.. end
|
|
