Openstack Object storage solution has been developed under the project called “swift”. It’s a multi-tenant object storage system and highly scalable one. It can manage large amounts of unstructured data at low cost through a RESTful HTTP API. swift-proxy-server service accepts OpenStack Object Storage API and raw HTTP requests to upload files, modify metadata, and create containers. It also serves file or container listings to web browsers. swift-account-server service manage accounts defined with Object Storage. swift-container-server service manages the mapping of containers /folders, within Object Storage. swift-object-server service manages actual objects,such as files, on the storage nodes.
For tutorial simplicity , we will configure the swift proxy service on Openstack controller node. For your information , you can run swift proxy on any node which are in storage node network. To improve the object storage performance , you should have multiple proxy nodes.
Configure Controller node for Object Storage:
1.Login to the Openstack Controller node.
2.Create the swift user for identity.
root@OSCTRL-UA:~# keystone user-create --name swift --pass swift123 +----------+----------------------------------+ | Property | Value | +----------+----------------------------------+ | email | | | enabled | True | | id | 47f4941be9fd421faa1cd72fb7abbb78 | | name | swift | | username | swift | +----------+----------------------------------+ root@OSCTRL-UA:~#
3.Add the admin role to the swift user.
root@OSCTRL-UA:~# keystone user-role-add --user swift --tenant service --role admin root@OSCTRL-UA:~#
4.Create the service entity.
root@OSCTRL-UA:~# keystone service-create --name swift --type object-store --description "OpenStack Object Storage" +-------------+----------------------------------+ | Property | Value | +-------------+----------------------------------+ | description | OpenStack Object Storage | | enabled | True | | id | 233aa2e309a142e188424ecbb41d1e07 | | name | swift | | type | object-store | +-------------+----------------------------------+ root@OSCTRL-UA:~#
5. Create the Object Storage service API endpoints.
root@OSCTRL-UA:~# keystone endpoint-create --service-id $(keystone service-list | awk '/ object-store / {print $2}') --publicurl 'http://OSCTRL-UA:8080/v1/AUTH_%(tenant_id)s' --internalurl 'http://OSCTRL-UA:8080/v1/AUTH_%(tenant_id)s' --adminurl http://OSCTRL-UA:8080 --region regionOne
+-------------+---------------------------------------------+
| Property | Value |
+-------------+---------------------------------------------+
| adminurl | http://OSCTRL-UA:8080 |
| id | 7f9042c48a5f401c8dd734e4047ced96 |
| internalurl | http://OSCTRL-UA:8080/v1/AUTH_%(tenant_id)s |
| publicurl | http://OSCTRL-UA:8080/v1/AUTH_%(tenant_id)s |
| region | regionOne |
| service_id | 233aa2e309a142e188424ecbb41d1e07 |
+-------------+---------------------------------------------+

6. Install the swift Controller node components and swift proxy.

8.Edit the “/etc/swift/proxy-server.conf” file on the below sections.
In the default section,
[DEFAULT] ... bind_port = 8080 user = swift swift_dir = /etc/swift
In the “pipeline:main” section.
[pipeline:main] pipeline = authtoken cache healthcheck keystoneauth proxy-logging proxy-server

[app:proxy-server] allow_account_management = true account_autocreate = true use = egg:swift#proxy
In “filter:keystoneauth” section,
[filter:keystoneauth] use = egg:swift#keystoneauth operator_roles = admin,_member_
In “filter:authtoken” section,
[filter:authtoken] paste.filter_factory = keystonemiddleware.auth_token:filter_factory auth_uri = http://OSCTRL-UA:5000/v2.0 identity_uri = http://OSCTRL-UA:35357 admin_tenant_name = service admin_user = swift admin_password = swift123 delay_auth_decision = 1
In “filter:cache” section,
[filter:cache] use = egg:swift#memcache memcache_servers = 127.0.0.1:11211
We have successfully configured the Object service for controller node. In the next article, we will see that how to configure the swift storage server.
