.. _swift-controller:
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 <http://docs.openstack.org/developer/swift/deployment_guide.html>`__.
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. However, for simplicity, this guide references the Identity service
in :doc:`keystone`. 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:
.. code-block:: console
$ . admin-openrc
#. To create the Identity service credentials, complete these steps:
* Create the ``swift`` user:
.. code-block:: console
$ openstack user create --domain default --password-prompt swift
User Password:
Repeat User Password:

| name | swift |
+-----------+----------------------------------+
* Add the ``admin`` role to the ``swift`` user:
.. code-block:: console
$ openstack role add --project service --user swift admin
.. note::
This command provides no output.
* Create the ``swift`` service entity:
.. code-block:: console
$ openstack service create --name swift \

Create and distribute initial rings
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Before starting the Object Storage services, you must create the initial
account, container, and object rings. The ring builder creates configuration
files that each node uses to determine and deploy the storage architecture.
For simplicity, this guide uses one region and two zones with 2^10 (1024)
maximum partitions, 3 replicas of each object, and 1 hour minimum time between
moving a partition more than once. For Object Storage, a partition indicates a
directory on a storage device rather than a conventional partition table.
For more information, see the
`Deployment Guide <http://docs.openstack.org/developer/swift/deployment_guide.html>`__.
.. note::
Perform these steps on the controller node.
Create account ring
-------------------
The account server uses the account ring to maintain lists of containers.
#. Change to the ``/etc/swift`` directory.
#. Create the base ``account.builder`` file:
.. code-block:: console
# swift-ring-builder account.builder create 10 3 1
.. note::
This command provides no output.
#. Add each storage node to the ring:
.. code-block:: console
# swift-ring-builder account.builder \
add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6002 \
--device DEVICE_NAME --weight DEVICE_WEIGHT
Replace ``STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS`` with the IP address
of the management network on the storage node. Replace ``DEVICE_NAME`` with a
storage device name on the same storage node. For example, using the first
storage node in :ref:`swift-storage` with the ``/dev/sdb`` storage
device and weight of 100:
.. code-block:: console
# swift-ring-builder account.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6002 --device sdb --weight 100
Repeat this command for each storage device on each storage node. In the
example architecture, use the command in four variations:
.. code-block:: console
# swift-ring-builder account.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6002 --device sdb --weight 100
Device d0r1z1-10.0.0.51:6002R10.0.0.51:6002/sdb_"" with 100.0 weight got id 0
# swift-ring-builder account.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6002 --device sdc --weight 100
Device d1r1z2-10.0.0.51:6002R10.0.0.51:6002/sdc_"" with 100.0 weight got id 1
# swift-ring-builder account.builder add \
--region 1 --zone 2 --ip 10.0.0.52 --port 6002 --device sdb --weight 100
Device d2r1z3-10.0.0.52:6002R10.0.0.52:6002/sdb_"" with 100.0 weight got id 2
# swift-ring-builder account.builder add \
--region 1 --zone 2 --ip 10.0.0.52 --port 6002 --device sdc --weight 100
Device d3r1z4-10.0.0.52:6002R10.0.0.52:6002/sdc_"" with 100.0 weight got id 3
#. Verify the ring contents:
.. code-block:: console
# swift-ring-builder account.builder
account.builder, build version 4
1024 partitions, 3.000000 replicas, 1 regions, 2 zones, 4 devices, 100.00 balance, 0.00 dispersion
The minimum number of hours before a partition can be reassigned is 1
The overload factor is 0.00% (0.000000)
Devices: id region zone ip address port replication ip replication port name weight partitions balance meta

#. Rebalance the ring:
.. code-block:: console
# swift-ring-builder account.builder rebalance
Reassigned 1024 (100.00%) partitions. Balance is now 0.00. Dispersion is now 0.00
Create container ring
---------------------
The container server uses the container ring to maintain lists of objects.
However, it does not track object locations.
#. Change to the ``/etc/swift`` directory.
#. Create the base ``container.builder`` file:
.. code-block:: console
# swift-ring-builder container.builder create 10 3 1
.. note::
This command provides no output.
#. Add each storage node to the ring:
.. code-block:: console
# swift-ring-builder container.builder \
add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6001 \
--device DEVICE_NAME --weight DEVICE_WEIGHT
Replace ``STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS`` with the IP address
of the management network on the storage node. Replace ``DEVICE_NAME`` with a
storage device name on the same storage node. For example, using the first
storage node in :ref:`swift-storage` with the ``/dev/sdb``
storage device and weight of 100:
.. code-block:: console
# swift-ring-builder container.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6001 --device sdb --weight 100
Repeat this command for each storage device on each storage node. In the
example architecture, use the command in four variations:
.. code-block:: console

Create object ring
------------------
The object server uses the object ring to maintain lists of object locations
on local devices.
#. Change to the ``/etc/swift`` directory.
#. Create the base ``object.builder`` file:
.. code-block:: console
# swift-ring-builder object.builder create 10 3 1
.. note::
This command provides no output.
#. Add each storage node to the ring:
.. code-block:: console
# swift-ring-builder object.builder \
add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6000 \
--device DEVICE_NAME --weight DEVICE_WEIGHT
Replace ``STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS`` with the IP address
of the management network on the storage node. Replace ``DEVICE_NAME`` with
a storage device name on the same storage node. For example, using the first
storage node in :ref:`swift-storage` with the ``/dev/sdb`` storage
device and weight of 100:
.. code-block:: console
# swift-ring-builder object.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6000 --device sdb --weight 100
Repeat this command for each storage device on each storage node. In the
example architecture, use the command in four variations:
.. code-block:: console
# swift-ring-builder object.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6000 --device sdb --weight 100
Device d0r1z1-10.0.0.51:6000R10.0.0.51:6000/sdb_"" with 100.0 weight got id 0
# swift-ring-builder object.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6000 --device sdc --weight 100
Device d1r1z2-10.0.0.51:6000R10.0.0.51:6000/sdc_"" with 100.0 weight got id 1
# swift-ring-builder object.builder add \
--region 1 --zone 2 --ip 10.0.0.52 --port 6000 --device sdb --weight 100
Device d2r1z3-10.0.0.52:6000R10.0.0.52:6000/sdb_"" with 100.0 weight got id 2
# swift-ring-builder object.builder add \
--region 1 --zone 2 --ip 10.0.0.52 --port 6000 --device sdc --weight 100
Device d3r1z4-10.0.0.52:6000R10.0.0.52:6000/sdc_"" with 100.0 weight got id 3

-----------------------------------
* Copy the ``account.ring.gz``, ``container.ring.gz``, and
``object.ring.gz`` files to the ``/etc/swift`` directory
on each storage node and any additional nodes running the
proxy service.

.. _swift-storage:
Install and configure the storage nodes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This section describes how to install and configure storage nodes
that operate the account, container, and object services. For
simplicity, this configuration references two storage nodes, each
containing two empty local block storage devices. The instructions
use ``/dev/sdb`` and ``/dev/sdc``, but you can substitute different
values for your particular nodes.
Although Object Storage supports any file system with
:term:`extended attributes (xattr)`, testing and benchmarking
indicate the best performance and reliability on :term:`XFS`. For
more information on horizontally scaling your environment, see the
`Deployment Guide <http://docs.openstack.org/developer/swift/deployment_guide.html>`_.
Prerequisites
-------------
Before you install and configure the Object Storage service on the
storage nodes, you must prepare the storage devices.
.. note::
Perform these steps on each storage node.
#. Install the supporting utility packages:
.. only:: ubuntu or debian
.. code-block:: console
# apt-get install xfsprogs rsync
.. only:: rdo
.. code-block:: console
# yum install xfsprogs rsync
.. only:: obs
.. code-block:: console
# zypper install xfsprogs rsync
#. Format the ``/dev/sdb`` and ``/dev/sdc`` devices as XFS:
.. code-block:: console
# mkfs.xfs /dev/sdb
# mkfs.xfs /dev/sdc
#. Create the mount point directory structure:
.. code-block:: console
# mkdir -p /srv/node/sdb
# mkdir -p /srv/node/sdc
#. Edit the ``/etc/fstab`` file and add the following to it:
.. code-block:: ini
/dev/sdb /srv/node/sdb xfs noatime,nodiratime,nobarrier,logbufs=8 0 2
/dev/sdc /srv/node/sdc xfs noatime,nodiratime,nobarrier,logbufs=8 0 2
#. Mount the devices:
.. code-block:: console
# mount /srv/node/sdb
# mount /srv/node/sdc
#. Create or edit the ``/etc/rsyncd.conf`` file to contain the following:
.. code-block:: ini
uid = swift
gid = swift
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
address = MANAGEMENT_INTERFACE_IP_ADDRESS
[account]
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/account.lock
[container]
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/container.lock
[object]
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/object.lock
Replace ``MANAGEMENT_INTERFACE_IP_ADDRESS`` with the IP address of the
management network on the storage node.
.. note::
The ``rsync`` service requires no authentication, so consider running
it on a private network in production environments.
.. only:: ubuntu or debian
7. Edit the ``/etc/default/rsync`` file and enable the ``rsync``
service:
.. code-block:: ini
RSYNC_ENABLE=true
8. Start the ``rsync`` service:
.. code-block:: console
# service rsync start
.. only:: obs or rdo
7. Start the ``rsyncd`` service and configure it to start when the
system boots:
.. code-block:: console
# systemctl enable rsyncd.service
# systemctl start rsyncd.service
Install and configure components
--------------------------------
.. include:: shared/note_configuration_vary_by_distribution.rst
.. note::
Perform these steps on each storage node.
#. Install the packages:
.. only:: ubuntu or debian
.. code-block:: console
# apt-get install swift swift-account swift-container swift-object
.. only:: rdo
.. code-block:: console
# yum install openstack-swift-account openstack-swift-container \
openstack-swift-object
.. only:: obs
.. code-block:: console
# zypper install openstack-swift-account \
openstack-swift-container openstack-swift-object python-xml
.. only:: ubuntu or rdo or debian
2. Obtain the accounting, container, and object service configuration
files from the Object Storage source repository:
.. code-block:: console
# curl -o /etc/swift/account-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/account-server.conf-sample?h=stable/mitaka
# curl -o /etc/swift/container-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/container-server.conf-sample?h=stable/mitaka
# curl -o /etc/swift/object-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/object-server.conf-sample?h=stable/mitaka
3. .. include:: swift-storage-include1.txt
4. .. include:: swift-storage-include2.txt
5. .. include:: swift-storage-include3.txt
6. Ensure proper ownership of the mount point directory structure:
.. code-block:: console
# chown -R swift:swift /srv/node
7. Create the ``recon`` directory and ensure proper ownership of it:
.. code-block:: console
# mkdir -p /var/cache/swift
# chown -R root:swift /var/cache/swift
# chmod -R 775 /var/cache/swift
.. only:: obs
2. .. include:: swift-storage-include1.txt
3. .. include:: swift-storage-include2.txt
4. .. include:: swift-storage-include3.txt
5. Ensure proper ownership of the mount point directory structure:
.. code-block:: console
# chown -R swift:swift /srv/node

The Object Storage services (swift) work together to provide
object storage and retrieval through a :term:`REST API <RESTful>`.
Your environment must at least include the Identity service (keystone)
prior to deploying Object Storage.
