Install and configure for Red Hat Enterprise Linux and CentOS

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 vmware-nsx-tempest-plugin database:

      CREATE DATABASE vmware-nsx-tempest-plugin;
      
    • Grant proper access to the vmware-nsx-tempest-plugin database:

      GRANT ALL PRIVILEGES ON vmware-nsx-tempest-plugin.* TO 'vmware-nsx-tempest-plugin'@'localhost' \
        IDENTIFIED BY 'VMWARE-NSX-TEMPEST-PLUGIN_DBPASS';
      GRANT ALL PRIVILEGES ON vmware-nsx-tempest-plugin.* TO 'vmware-nsx-tempest-plugin'@'%' \
        IDENTIFIED BY 'VMWARE-NSX-TEMPEST-PLUGIN_DBPASS';
      

      Replace VMWARE-NSX-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 vmware-nsx-tempest-plugin user:

      $ openstack user create --domain default --password-prompt vmware-nsx-tempest-plugin
      
    • Add the admin role to the vmware-nsx-tempest-plugin user:

      $ openstack role add --project service --user vmware-nsx-tempest-plugin admin
      
    • Create the vmware-nsx-tempest-plugin service entities:

      $ openstack service create --name vmware-nsx-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
    
  1. Edit the /etc/vmware-nsx-tempest-plugin/vmware-nsx-tempest-plugin.conf file and complete the following actions:

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

      [database]
      ...
      connection = mysql+pymysql://vmware-nsx-tempest-plugin:VMWARE-NSX-TEMPEST-PLUGIN_DBPASS@controller/vmware-nsx-tempest-plugin
      

Finalize installation

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

# systemctl enable openstack-vmware-nsx-tempest-plugin-api.service

# systemctl start openstack-vmware-nsx-tempest-plugin-api.service
