Install and configure Placement for Red Hat Enterprise Linux and CentOS Stream

This section describes how to install and configure the placement service when using Red Hat Enterprise Linux or CentOS Stream packages.

Prerequisites

Before you install and configure the placement service, you must create a database, service credentials, and API endpoints.

Create Database

1. To create the database, complete these steps:

   • Use the database access client to connect to the database server as the root user:

     $ mysql -u root -p

   • Create the placement database:

     MariaDB [(none)]> CREATE DATABASE placement;

   • Grant proper access to the database:

     MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' \
       IDENTIFIED BY 'PLACEMENT_DBPASS';
     MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' \
       IDENTIFIED BY 'PLACEMENT_DBPASS';

     Replace PLACEMENT_DBPASS with a suitable password.

   • Exit the database access client.

Configure User and Endpoints

Install and configure components

1. Install the packages:

   # dnf install openstack-placement-api

2. Edit the /etc/placement/placement.conf file and complete the following actions:

   • In the [placement_database] section, configure database access:

     [placement_database]
     # ...
     connection = mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement

     Replace PLACEMENT_DBPASS with the password you chose for the placement database.

   • In the [api] and [keystone_authtoken] sections, configure Identity service access:

     [api]
     # ...
     auth_strategy = keystone
     
     [keystone_authtoken]
     # ...
     auth_url = http://controller:5000/v3
     memcached_servers = controller:11211
     auth_type = password
     project_domain_name = Default
     user_domain_name = Default
     project_name = service
     username = placement
     password = PLACEMENT_PASS

     Replace PLACEMENT_PASS with the password you chose for the placement user in the Identity service.

     Note

     Comment out or remove any other options in the [keystone_authtoken] section.

     Note

     The value of user_name, password, project_domain_name and user_domain_name need to be in sync with your keystone config.

3. Populate the placement database:

   # su -s /bin/sh -c "placement-manage db sync" placement

   Note

   Ignore any deprecation messages in this output.

Finalize installation

• Restart the httpd service:

  # systemctl restart httpd
