Install and configure the controller node for Debian

Install and configure the controller node for Debian

This section describes how to install and configure the proxy service that handles requests for the account, container, and object services operating on the storage nodes. For simplicity, this guide installs and configures the proxy service on the controller node. However, you can run the proxy service on any node with network connectivity to the storage nodes. Additionally, you can install and configure the proxy service on multiple nodes to increase performance and redundancy. For more information, see the Deployment Guide.

This section applies to Debian.

Prerequisites

The proxy service relies on an authentication and authorization mechanism such as the Identity service. However, unlike other services, it also offers an internal mechanism that allows it to operate without any other OpenStack services. Before you configure the Object Storage service, you must create service credentials and an API endpoint.

Note

The Object Storage service does not use an SQL database on the controller node. Instead, it uses distributed SQLite databases on each storage node.

  1. Source the admin credentials to gain access to admin-only CLI commands:

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

    • Create the swift user:

      $ openstack user create --domain default --password-prompt swift
      User Password:
      Repeat User Password:
      +-----------+----------------------------------+
      | Field     | Value                            |
      +-----------+----------------------------------+
      | domain_id | default                          |
      | enabled   | True                             |
      | id        | d535e5cbd2b74ac7bfb97db9cced3ed6 |
      | name      | swift                            |
      +-----------+----------------------------------+
      
    • Add the admin role to the swift user:

      $ openstack role add --project service --user swift admin
      

      Note

      This command provides no output.

    • Create the swift service entity:

      $ openstack service create --name swift \
        --description "OpenStack Object Storage" object-store
      +-------------+----------------------------------+
      | Field       | Value                            |
      +-------------+----------------------------------+
      | description | OpenStack Object Storage         |
      | enabled     | True                             |
      | id          | 75ef509da2c340499d454ae96a2c5c34 |
      | name        | swift                            |
      | type        | object-store                     |
      +-------------+----------------------------------+
      
  3. Create the Object Storage service API endpoints:

    $ openstack endpoint create --region RegionOne \
      object-store public http://controller:8080/v1/AUTH_%\(project_id\)s
    +--------------+----------------------------------------------+
    | Field        | Value                                        |
    +--------------+----------------------------------------------+
    | enabled      | True                                         |
    | id           | 12bfd36f26694c97813f665707114e0d             |
    | interface    | public                                       |
    | region       | RegionOne                                    |
    | region_id    | RegionOne                                    |
    | service_id   | 75ef509da2c340499d454ae96a2c5c34             |
    | service_name | swift                                        |
    | service_type | object-store                                 |
    | url          | http://controller:8080/v1/AUTH_%(project_id)s |
    +--------------+----------------------------------------------+
    
    $ openstack endpoint create --region RegionOne \
      object-store internal http://controller:8080/v1/AUTH_%\(project_id\)s
    +--------------+----------------------------------------------+
    | Field        | Value                                        |

    | region       | RegionOne                                    |
    | region_id    | RegionOne                                    |

Install and configure components

Note

Default configuration files vary by distribution. You might need to add these sections and options rather than modifying existing sections and options. Also, an ellipsis (...) in the configuration snippets indicates potential default configuration options that you should retain.

  1. Install the packages:

    # apt-get install swift swift-proxy python-swiftclient \
      python-keystoneclient python-keystonemiddleware \
      memcached
    

    Note

    Complete OpenStack environments already include some of these packages.

    1. Create the /etc/swift directory.

    2. Obtain the proxy service configuration file from the Object Storage source repository:

      # curl -o /etc/swift/proxy-server.conf https://opendev.org/openstack/swift/raw/branch/stable/rocky/etc/proxy-server.conf-sample
