Install and configure the controller node¶

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.

Voraussetzungen¶

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. However, for simplicity, this guide references the Identity service in Identitätsdienst. Before you configure the Object Storage service, you must create service credentials and an API endpoint.

Bemerkung

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

Sourcen Sie die admin Anmeldeinformationen, um Zugriff auf die Admin-Kommandos zu bekommen:
```
$ . admin-openrc
```

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 | e0353a670a9e496da891347c589539e9 |
| enabled   | True                             |
| id        | d535e5cbd2b74ac7bfb97db9cced3ed6 |
| name      | swift                            |
+-----------+----------------------------------+

Add the admin role to the swift user:
```
$ openstack role add --project service --user swift admin
```
Bemerkung

Das Kommando erzeugt keine Ausgabe.

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                     |
+-------------+----------------------------------+

Create the Object Storage service API endpoints:

$ openstack endpoint create --region RegionOne \
  object-store public http://controller:8080/v1/AUTH_%\(tenant_id\)s
+--------------+----------------------------------------------+
| Field        | Value                                        |

Installieren und konfigurieren von Komponenten¶

Bemerkung

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.

Installieren Sie die Pakete:

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

Bemerkung

Complete OpenStack environments already include some of these packages.

Create the /etc/swift directory.

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

# curl -o /etc/swift/proxy-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/proxy-server.conf-sample?h=stable/mitaka
