Code Issues Proposed changes

Doug Hellmann c7bfdbb44f split install guide into separate files by OS 
Provide a script for interpreting the "only" directives and splitting
the existing content up into standalone files for each OS to make it
easier for project teams to copy the parts they need into their own
project documentation trees without requiring separate platform builds.

The files have been hand-edited to pass the niceness check and to allow
the install guide to build.

The script for building the guide has been changed to not build separate
copies per OS.

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.

Install and configure components

  1. Install the packages:
# yum install mariadb mariadb-server python2-PyMySQL
  1. 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:

      [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

Finalize installation

  1. Start the database service and configure it to start when the system boots:
# systemctl enable mariadb.service
# systemctl start mariadb.service

  1. 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
