Install and configure for Red Hat Enterprise Linux and CentOS

This section describes how to install and configure the openstack service for Red Hat Enterprise Linux 7 and CentOS 7.

Prerequisites

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

  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 zun_tempest_plugin database:

      CREATE DATABASE zun_tempest_plugin;
      
    • Grant proper access to the zun_tempest_plugin database:

      GRANT ALL PRIVILEGES ON zun_tempest_plugin.* TO 'zun_tempest_plugin'@'localhost' \
        IDENTIFIED BY 'ZUN_TEMPEST_PLUGIN_DBPASS';
      GRANT ALL PRIVILEGES ON zun_tempest_plugin.* TO 'zun_tempest_plugin'@'%' \
        IDENTIFIED BY 'ZUN_TEMPEST_PLUGIN_DBPASS';
      

      Replace ZUN_TEMPEST_PLUGIN_DBPASS with a suitable password.

    • Exit the database access client.

      exit;
      
  2. Source the admin credentials to gain access to admin-only CLI commands:

    $ . admin-openrc
    
  3. To create the service credentials, complete these steps:

    • Create the zun_tempest_plugin user:

      $ openstack user create --domain default --password-prompt zun_tempest_plugin
      
    • Add the admin role to the zun_tempest_plugin user:

      $ openstack role add --project service --user zun_tempest_plugin admin
      
    • Create the zun_tempest_plugin service entities:

      $ openstack service create --name zun_tempest_plugin --description "openstack" openstack
      
  4. Create the openstack service API endpoints:

    $ openstack endpoint create --region RegionOne \
      openstack public http://controller:XXXX/vY/%\(tenant_id\)s
    $ openstack endpoint create --region RegionOne \
      openstack internal http://controller:XXXX/vY/%\(tenant_id\)s
    $ openstack endpoint create --region RegionOne \
      openstack admin http://controller:XXXX/vY/%\(tenant_id\)s
    

Install and configure components

  1. Install the packages:

    # yum install
    

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

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

    [database]
    ...
    connection = mysql+pymysql://zun_tempest_plugin:ZUN_TEMPEST_PLUGIN_DBPASS@controller/zun_tempest_plugin
    

Finalize installation

Start the openstack services and configure them to start when the system boots:

# systemctl enable openstack-zun_tempest_plugin-api.service

# systemctl start openstack-zun_tempest_plugin-api.service
