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 openSUSE Leap 42.1 and SUSE Linux Enterprise Server 12 SP1.
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.
Source the admin
credentials to gain access to admin-only CLI commands:
$ . 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
Note
This command provides no output.
Create the swift
service entity:
$ openstack service create --name swift \
--description "OpenStack Object Storage" object-store
+-------------+----------------------------------+
| Field | Value |

Create the Object Storage service API endpoints:
$ openstack endpoint create --region RegionOne \

| Field | Value |

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.
Install the packages:
# zypper install openstack-swift-proxy python-swiftclient \
python-keystoneclient python-keystonemiddleware \
python-xml memcached
Note
Complete OpenStack environments already include some of these packages.
Edit the /etc/swift/proxy-server.conf
file and complete the
following actions:
In the [DEFAULT]
section, configure the bind port, user, and
configuration directory:
[DEFAULT]
...
bind_port = 8080
user = swift
swift_dir = /etc/swift
In the [pipeline:main]
section, remove the tempurl
and
tempauth
modules and add the authtoken
and keystoneauth
modules:
[pipeline:main]
pipeline = catch_errors gatekeeper healthcheck proxy-logging cache container_sync bulk ratelimit authtoken keystoneauth container-quotas account-quotas slo dlo versioned_writes proxy-logging proxy-server
Note
Do not change the order of the modules.
Note
For more information on other modules that enable additional features, see the Deployment Guide.
In the [app:proxy-server]
section, enable automatic account creation:
[app:proxy-server]
use = egg:swift#proxy
...
account_autocreate = True
In the [filter:keystoneauth]
section, configure the operator roles:
[filter:keystoneauth]
use = egg:swift#keystoneauth
...
operator_roles = admin,user
In the [filter:authtoken]
section, configure Identity service access:
[filter:authtoken]
paste.filter_factory = keystonemiddleware.auth_token:filter_factory
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = swift
password = SWIFT_PASS
delay_auth_decision = True
Replace SWIFT_PASS
with the password you chose for the swift
user
in the Identity service.
Note
Comment out or remove any other options in the [filter:authtoken]
section.
In the [filter:cache]
section, configure the memcached
location:
[filter:cache]
use = egg:swift#memcache
...
memcache_servers = controller:11211
